    Habitat & Ecology — Altitude: up to 450 m. Flowering: unknown; fruiting: February, April, July, August.

    Uses — Arillode edible, with a bitter aftertaste.

    Vernacular names — Borneo: Kampul (Dayak).

    Note — In Baccaurea the vegetative parts of male and female plants usually closely resemble each other. This species, however, causes some interpretation problems, because the similarity between male and female is not 100%. The male type specimen is clearly different from all other material. Three fruiting specimens resemble this male specimen most (they do not t into other species). The female flowering and fruiting specimens, that traditionally have been included here, are hesitantly accepted by me.

    Habitat & Ecology — Primary rain forest. Altitude: sea level up to 450 m. Soil: sand, clay. Flowering: May, July to November; fruiting: May, July to September, November.

    Vernacular names — Sumatra: Bergang gaya, birah mato, djatikau, djentikan betima, djentikan merah, merah matu, tampoei. Simeuluλ Island: Bolawah ontur, bolawah silai. Bangka: Kepris, ketjepat, masput, rankop, rankup. Borneo: Jelentikan (Kutai); keliwat’n (Benuag/Tunjun); lubi, tampoi.

    Notes — Mόller Argoviensis (1866) already noted that this species is very similar to B. costulata. Airy Shaw (1975) regarded the two as conspecic, with no further explanation. In my opinion, however, the two species are rather different, and the confusion must have been due to incomplete data. The leaves of B. deflexa tend to be larger than those of B. costulata; the midrib (lower surface) usually densely hairy, compared with usually sparsely hairy; the staminate inflorescences less lax, always densely hairy (often sparsely hairy in B. costulata), bracts 0.5–1 mm long, compared with 1–2.5 mm long; stamens (4–)6, compared with 4 or 5, 0.3–0.6 mm long, in contrary to 0.2–0.3 mm long. These differences together with the different appearance of both species in the herbarium material (B. deflexa dark brown, B. costulata more glossy, greyish brown) have me led to conclude that B. deflexa and B. costulata are not conspecic. I omitted the pistillate inflorescences and infructescences from the discussion because of insufcient knowledge of these characters in B. costulata (see note under B. costulata).

    Habitat & Ecology — Riverine rain forest. Altitude: 0–700 m. Soil: yellow sand, loam. Fruiting: February, July, October.

    Uses — Arillode edible.

    Vernacular names — Sarawak: Buah jelentik (Iban).

    Note — Airy Shaw synonymised B. dolichobotrys with B. hookeri (= B. polyneura). Baccaurea dolichobotrys is in my opinion clearly different from B. polyneura. The indument on the branches is sparsely hairy in B. dolichobotrys, whereas B. polyneura is densely hairy (B. dolichobotrys is in general less hairy than B. polyneura); the petioles and leaves are on average longer in B. dolichobotrys; the fruits are 10–10.5 mm diam., compared with 12–26 in B. polyneura. Other characters (such as colour of the leaves when dry) differ in range but usually overlap.

    Note — Airy Shaw (1975) mentioned this species as a synonym of B. parviflora with a question mark. However, after studying the type material and the original de­scriptions, I am convinced that this species is conspecic with B. membranacea and B. trunciflora, and distinct from B. parviflora. Especially the fruit is utterly different, in the number of locules (B. odoratissima 2-locular, B. parviflora 3-locular) as well as in the fruit shape (globose in B. odoratissima, fusiform in B. parviflora).

    Habitat & Ecology — Primary and secondary evergreen forest, steep hillsides to dry parts of swamps to alluvial forest. Soil: sandstone, white sandy soil. Altitude: sea level up to 1250 m. Flowering: November to June, September; fruiting: March to December.

    Uses — Wood used as boxwood. Pericarp and arillode edible, sour-sweet.

    Vernacular names — Thailand: Somfai Pah. Peninsular Malaysia: Tamun (Batec); kentamun ayer (Temuan); asam tambun, belembik, dedali, engkuni, setambun, tambun. Borneo: Bamotong-belaboh (Bassap-Mapulu); belembik plandoek, engkuni, konkuni, mata pelanduk.

    Notes — 1. Baccaurea parviflora is rather heterogeneous in some characters, espe­cially in the fruits. Kiew (1997) re-established the name B. scortechinii, based purely on material from the Peninsular Malaysia. She listed 19 differential characters. I checked all these characters, except for the fruit colour because this character is im­possible to study when only herbarium material is available. She mentioned this as one of the problems of species delimitation in this complex (B. parviflora and B. scortechinii). All 19 characters listed overlap. The values given by Kiew are mean values only. Collections from Sumatra made by De Wilde & De Wilde-Duyfjes in Gunung Leuser Park overlap in all characters. According to Kiew, the most important difference is the position of the inflorescences in combination with fruit shape. Baccaurea scortechinii flowers at the trunk and branches, and has ridged fruits, while B. parviflora flowers at the base of the trunk, and has no ridges at the fruits. However, contrary to these observations, M. van Balgooy photographed a tree, which flowered at the base of the trunk, and had ridged fruits. In July 1998 I observed the same phenomenon in the FRIM campus in Kepong (Photo 8). My conclusion is that these two taxa are conspecic.

2. In 1997 Kiew erroneously typied B. parviflora. She mentioned Wallich 7759B (K) as the type specimen. This, however, is an isotype of B. affinis. In the original description of Pierardia parviflora Mόller Argoviensis (1863) quoted: “Wall.! absque no. in hb. DC”. I have checked G-DC on microche, but could not recover this specimen. The lectotype Wallich 1849 (K, Lectotype, designated by Haegens, 2000) has no original number and has been studied by Mόller Argoviensis as notes in his handwriting are found on the sheet. Later the numbers 1849 and 7759B were added, of which number 7759B is crossed out again.

3. Another extremely closely related Burmese and Thai taxon is B. ptychopyxis. This species, however, always has axillary staminate inflorescences, and is ramiflorous to cauline only as an exception. Baccaurea parviflora is always strictly cauliflorous. The staminate inflorescences in B. ptychopyxis are solitary, whereas B. parviflora has dense clusters. Besides these differences there are some minor characters, such as the fruit length is in B. ptychopyxis 17–20.3 mm, and in B. parviflora 16–32 mm. The material of B. ptychopyxis is, however, very incomplete. Therefore B. ptychopyxis is here interpreted as a species separate from B. parviflora.

4. See note under B. odoratissima.

    Note — Although I had no opportunity to study the lectotype, I am convinced that B. kunstleri is conspecic with B. polyneura. The following paratypes of B. kunstleri were studied by me: Ridley 6670, 6163, and Goodenough 5084. I was unable to separate the numerous other specimens I have studied into two taxonomic entities.

    Habitat & Ecology — Primary rain forest and cultivated. Soil: sand, granite. Altitude 50–1700 m. Flowering: December to June, September; fruiting: throughout the year.

    Uses — Arillode edible, sweet to sour.

    Vernacular names — Burma: Kanaso. Thailand: Mahphie. Peninsular Malaysia: Tampoi.

    Notes — 1. The front side of the type sheet (BM: 31252) of B. ramiflora refers to page 662 of Fl. Cochinch. and B. sylvestris. This is certainly wrong, because the specimen does not correspond with the description of B. sylvestris. The back side of this sheet refers to page 661 of Fl. Cochinch., where B. ramiflora is described.

2. The type of B. cauliflora is probably lost. There is no original illustration. It is therefore not possible to lectotypify this name. From the description it is however obvious that this name is conspecic with B. ramiflora. It is here therefore neotypied. Fleury 32043 is chosen as neotype, because it is a collection from Cochinchine, and it is a fruiting specimen like the original specimen described by Loureiro.

3. The type sheet of B. sylvestris is a mixture. The leaves on this sheet are Lancium domesticum Corrκa, see Mabberley et al. (1995). The description of Loureiro is also congruent with Lancium domesticum. The fruits, for example, contain 5 locules, and each locule has one ovule only (both features not present in Baccaurea). The inflores­cences on the type sheet, on the other hand, belongs to B. ramiflora. The fact that the type specimen is a mixture has probably caused the confusion about the taxonomical status of B. sylvestris.

    Habitat & Ecology — Flowering: June, September, November, December; fruiting: February, May.

    Vernacular names — Simeuluλ Island: Awa-batoe-fatoeh, bolahna itung, bolawah-iteung-delok, bolawah ontur, bolawah palo, bolawah pajo-oeding, bolawah silai, soerai-datan, toetoen bolafah.

    Notes — 1. In this species all staminate flowers in herbarium material fall off before anthesis. In B. bracteata, a close relative, a part of the staminate flowers show the same phenomenon. However, despite the fact that the staminate flowers remain closed, pollination takes place because in the fruit bearing specimen seeds are produced. A possible explanation for the successful pollination could be that the breaking off of the unopened flowers is an artifact, and that the flowers do open in the wild. Another explanation could be that fertilisation is performed by thrips, who are able to enter the closed flowers.

2. This species is named for its restricted distribution on Simeuluλ Island, off the coast of Sumatra. All studied collections of this species were made by Achmad, and he spelled the island as Simaloer.

    Habitat & Ecology — Primary and secondary rain forest, and swamp forest. Soil: sand, clay, loam. Altitude: up to 1500 m. Flowering and fruiting: throughout the year. Flowers odourless.

    Uses — Arillode edible, sweet to sour.

    Vernacular names — Borneo (Brunei): Kunau; mata kunau (Malay). Borneo (Sabah): Kunau-kunau, mata-pelandok. Borneo (Sarawak): Enkuni(k), kunau (Iban); sekunau (Dusun); kuni, mata pelandok. Borneo (Kalimantan): Pundung undang (Dayak); konkuning, mata pelandoeh. Philippines: Katag, saket.

    Note — In the type of B. stipulata the leaf blades are 13–19 cm long and whitish when dry, whereas in the type of B. tetrandra the leaf blades are 6–14 cm long and brown when dry. However, intermediates between these characters are found frequent­ly. The same variability is found in the leaf anatomical characters (Bodegom et al., in prep.). Baccaurea stipulata is therefore considered to be conspecic with B. tetrandra.

No original material of the following taxa could be traced or obtained so that their taxonomic status could not be evaluated.

Pierardia macrostachys Wight & Arn., Icon. Pl. Ind. Orient. (1852) 30; Baill., Adansonia 3 (1863) 140. — Lectotype (designated by Haegens, 2000): Wight (lecto plate 1912 in Wight & Arn., Icon. Pl. Ind. Orient. (1852) 28).

    Hooker (1885) has considered this name a synonym of B. sapida (= B. ramiflora). The original description and plate of B. macrostachys are, however, not congruent with Hooker’s description of B. sapida. The original description and plate of B. macrostachys are also incongruent with the modern description of B. ramiflora (see no. 34). In B. macrostachys (5–)8–10 stamina are present, whereas B. ramiflora has 5–8 stamina. In my opinion, the plant with staminate inflorescences depicted in Wight & Arn. (1852: plate 1912) is a true Baccaurea, but is maybe not conspecic with B. ramiflora. The drawing is too crude to establish the exact identity of the depicted plant. Two oddities appear in the description and on plate 1913 (Wight & Arn., 1852) of the plant with pistillate inflorescences and infructescence: the seed has no arillode; the leaves are opposite (but Wight & Arn. were not sure if the leaves belonged to the fruits). For these reasons it is extremely questionable if the female plant is a Baccaurea. The plate with the staminate flowers is therefore chosen as lectotype.
