BLUMEA

A taxonomic revision of Amaracarpus Blume (Rubiaceae, Psychotrieae) is presented. The salient characteristics of Amaracarpus are given, with particular attention to the differences between Amaracarpus, Dolianthus and Psychotria. The taxonomic account includes a key to species, an informal (artificial) subgeneric classification, full descriptions, and a list of specimens examined. Amaracarpus comprises 22 species: six new combinations are proposed, one new species is described, eight species are moved to other genera, the transfer of 12 species to Psychotria is confirmed, and numerous taxa are placed into synonymy. A checklist of all Amaracarpus names is provided.

Review of the genus Solena (Cucurbitaceae)

W.J.J.O. de Wilde & B.E.E. Duyfjes

The genus Solena Lour. is redefined, and its 3 species and 1 subspecies are keyed out and described: S. amplexicaulis occurs in S India, S. heterophylla, with 2 subspecies is widespread, but does not occur in S India, and S. umbellata (Klein ex Willd.) W.J. de Wilde & Duyfjes, comb. nov., occurs in S India and Sri Lanka. The status of S. heterophylla subsp. napaulensis (Ser.) W.J. de Wilde & Duyfjes, comb. & stat. nov. needs further study as this subspecies is very similar to the more widespread subsp. heterophylla, but it is distinct by sigmoid thecae. Solena amplexicaulis is taxonomically more distinct from the other two species of Solena. In southern India Kedrostis foetidissima much resembles Solena in general habit, especially by the more or less amplexicaul leaves, and therefore it is discussed and keyed out against Solena.

Revision of Ochrosia (Apocynaceae) in Malesia

Hendrian

The genus Ochrosia Juss. is revised in the Malesian region. Thirteen species are recognized as Ochrosia, including one new species, O. basistamina. Seven species previously placed in Neisosperma Raf. are now included in Ochrosia.

The names Ochrosia section Echinocaryon F. Muell. and Ochrosia section Ochrosia are applied for the fibrous-fruited species and cavity-fruited species of Ochrosia, respectively. Neisosperma Raf. is reduced to Ochrosia section Echinocaryon F. Muell.

Separate keys are given for the species of both sections.

Characterisation of a novel fruit type found in Ehretia (Ehretiaceae, Boraginales)

Marc Gottschling & Hartmut H. Hilger

Ehretia (Ehretiaceae, Boraginales) has been divided into two major clades, characterised by fruits with four endocarpids (Ehretia I, including species of Ehretia formerly belonging to Rotula) and by fruits with two endocarpids (Ehretia II, plus E. microphylla (= Carmona retusa) with an undivided endocarp), respectively. Both molecular (ITS1) and morphological data support the recognition of an additional clade, Ehretia III (E. longiflora species group). Its representatives are characterised by four endocarpids (as in Ehretia I), but differ in the presence of distinct lamellae on the abaxial surface of each endocarpid (as in Bourreria, also belonging to Ehretiaceae). However, molecular data suggest a close relationship with Ehretia II. At least three species belong to Ehretia III: Chinese E. longiflora, eastern Indian E. wallichiana, and Indonesian E. javanica.

Flora Malesiana precursor for the treatment of Moraceae 6: Ficus subgenus Sycomorus

C.C. Berg

The sections of Ficus subg. Sycomorus are described and their Malesian species listed and keyed out. Six new species are described in the subgenus: Ficus albomaculata, F. biakensis, F. boanensis, F. limosa, F. manuselensis, F. morobensis, F. remifolia, F. rubrosyce, F. scopulifera; and one new subspecies: F. botryocarpa Miq. subsp. hirtella C.C. Berg. The new combinations F. botryocarpa Miq. subsp. subalbidoramea (Elmer) C.C. Berg, F. porrecta (Corner) C.C. Berg, F. trichocerasa Diels subsp. pleioclada (Diels) C.C. Berg are also made. The following new sections and subsection are proposed: Subg. Sycomorus sect. Bosscheria (Teijsm. & de Vriese) C.C. Berg, sect. Dammaropsis (Warb.) C.C. Berg, sect. Papuasyce (Corner) C.C. Berg, and subsect. Neomorphe (King) C.C. Berg.
