S.E.C. Sierra, P.C. van Welzen & J.W.F. Slik
A revision of Mallotus section Philippinenses (former section Rottlera) in Malesia and Thailand is given. Descriptions, distribution maps, habit drawings, and a key to the species are provided. The diagnostic characters for the section are briefly discussed. Five species (M. kongkandae, M. leptostachyus, M. pallidus, M. philippensis, and M. repandus) are recognised. Mallotus chromocarpus is excluded from the section because it has more shared characters with the monospecific genus Octospermum, like the presence of indehiscent fruits, absence of stipules, marginal extrafloral nectaries on the upper side of the leaf blade, broad connectives (shaped umbrella-like), and its occurrence in New Guinea, and is therefore probably closely related to it.

S.E.C. Sierra & P.C. van Welzen
A revision of Mallotus section Mallotus in Malesia is given. Descriptions, distribution maps, habit drawings and a key to all species are provided. The diagnostic characters for the section are briefly discussed. Four species (M. barbatus, M. macrostachyus, M. mollissimus, M. paniculatus) and one variety (M. paniculatus var. formosanus) are recognised.

P.C. van Welzen & S.E.C. Sierra
Lasiococca brevipes (Merr.) Welzen & S.E.C. Sierra is a new combination based on Mallotus brevipes Merr. The new combination replaces Lasiococca malaccensis Airy Shaw, which appears to be a later synonym. The species is very rare, but widespread and seemingly with a very disjunct distribution, found in Sumatra, the Philippines, Sulawesi, and the Lesser Sunda Islands.

P.H. Hovenkamp & F. Miyamoto
All species of the genus Nephrolepis are reviewed and described. 19 species are recognized, with 3 varieties, and 7 putative or confirmed hybrids are briefly discussed. Two new combinations are made, of which one as the result of a transferral of species to varietal rank. One variety and two hybrids are described as new. A change of name is proposed for the commonly recognized N. falcata and N. multiflora.

J. Kuijt & D. Lye
The foliar sclerenchyma of all genera of neotropical Loranthaceae is surveyed by means of cleared leaves, using selected species. Three general categories of sclerenchyma are recognized. Fibers may form discontinuous or continuous bundles associated with veins or, more rarely, occur as individual cells. Sclereids, often of the astrosclereid type, are present in varying concentrations, or may be absent. Cristarque cells are very common, and occasionally extremely abundant, but are lacking in several genera. The survey includes information on terminal tracheids which are almost invariably present. Attention is drawn to the systematic significance of sclerenchyma where warranted.

H. Rischer, G. Heubl, H. Meimberg, M. Dreyer, H.A. Hadi & G. Bringmann
Ancistrocladus benomensis Rischer & G. Bringmann, a new species from Gunung Benom, Malaysia is described and illustrated. Diagnostic notes concerning morphology, occurrence of specific naphthylisoquinoline alkaloids, and support from molecular analyses are provided.

A.R.A. Görts-van Rijn & R. Callejas Posada
Three new species of Piper from the Guianas and adjacent areas are described: Piper aulacospermum Callejas, P. ciliomarginatum Görts & Christenh. and P. remotinervium Görts. The differences between P. aulacospermum and P. bartlingianum (Miq.) C.DC., both belonging to subg. Ottonia, are given as well as notes on all three species.

Boraginaceae is expanded to comprise seven subfamilies, two of which are based on Hydrophyllaceae and Lennoaceae, respectively. The type species of Tournefortia sect. Tournefortia is transferred to Heliotropium, as are its Malesian–Australian representatives.

Evidence from both morphological and molecular phylogenetic data support the view that the circumscissile calycine calyptra, the sole defining character of Cleistocalyx, has multiple origins within Syzygium s.l. and is therefore an invalid basis for generic circumscription. Accordingly, the Fijian Cleistocalyx are transferred to Syzygium, and the new combinations Syzygium decussatus, S. eugenioides and S. seemannii, are made. Syzygium myrtoides is reinstated, and Cleistocalyx ellipticus, C. longiflorus, C. kasiensis and C. seemannii var. punctatus are reduced to the synonymy of S. seemannii. The distribution of S. seemannii is extended to Vanuatu.

L.S. Juswara & L.A. Craven
The Hibiscus panduriformis Burm.f. species complex in Australia is revised. Six species are recognised, of which one is the widespread H. panduriformis; one, H. austrinus, is based upon H. panduriformis var. australis; and four represent new species, H. apodus, H. calcicola, H. fluvialis, and H. multilobatus. A new variety is recognised in H. austrinus, namely var. occidentalis. Distribution maps are provided for all taxa and an exsiccatae list is included.

Some name changes and new names are published belonging to a new revision of Symplocaceae of the Old World. Several species described after 1975 were reduced. [With CD-Rom.]
