New synonym: Dysoxylum undulatum Henderson in Gard. Bull., Straits Settl. 7: 90. 1933 — Henderson 23484 (fl.) et 23624, fr. (BO, SING). The species does not occur in Java. The Javanese specimens, enume- rated by Koorders belong to another (undescribed ?) species. The species is close to D, schultzii which differs by its visible lateral nerves (invisible in mature leaves of D. acutangulum) and by the presence of tiny domatial cavities along the midrib. There are also floral differences. The timber is excellent and one of the most superior of the endemic Meliaceae. The characteristic of opposite leaves in D. acutangulum does not hold true absolutely; in some specimens they alternate.

Didymocheton pruriens Zippel is cited by Miquel under his Dysoxylum setosum; Miquel mentioned also a specimen of Zippel from Amboina under D. sessile. As D. setosum is not prurient at all, there remains the possibi- lity that D. pruriens is identical with our Didymocheton sessile.

Described by Didrichsen in Vidensk. Meddel.

Br. (the flowers) and a species of StercuUa (the leaves). Arguments in - favour of this are: Pterocymbium flowers, when the tree is completely leaf-- less, hence collectors take recourse usually to seedlings as an addition, to the flowering material. Pterocymbium has always almost rounded, cordate leaves (rarely oval). Additional material from the Nicobar and Andaman Islands proves that only Pterocymbium javanieum occurs there, which are the flowers of Pt. nicobaricum; the leaves of later collections are always those of the real Pt. javanieum. The flowers of Pt. javanicum from Burma, Siam, Nicobar and Andaman Isl. are slightly smaller than those from the Malesian area. Eventually they might prove to belong to a separate species, originally named: Sterculia campanulata Wallich. A clue to this might be the colour of the flower. Some Javanese material has the same: small-sized flowers. Additional records: Andamans, Guitar Isl., Febr. - March, fl,, Kirat Ram 3772 [DD] with a flowering bunch, matching. Didrichsen's material perfectly and a leafy branch of Pterocymbium javanieum; Stewart Isl., N.

Baratang, Parkin- son 308 [DD]. I suspect thaf Pt. dussaudii Tardieu (in Not. Syst. 10: 240. 1942) is likewise based on two discordant elements; the specimen Dussaud 117 (P) has flowers of Pt. javanicum and detached leaves of a Sterculia-.

P t e r o c y m b i u m j a v a n i c u m R. Br. and P t . t i n c i t o r i u m Merr. I have considered Pt. javanicum a variety of Pt. tinctorium. Since I have been able to study both species in the field, it has been proved that these belong to two different species, not only differing in the colour of the flowers-, but also in the size of the flowers and differences in the andro- gynophore. Moreover, the areas of distribution exclude each other. P t e r o s p e r m u m b l u m e a n u m Korth. and P t . j a v a n i c u m Jungh. In Backer and Bakhuizen's Flora of Java (1: 409 - 410. 1963) these two species are treated as being conspecific, following Koorders & Valeton. The latter recognized a variety montanum, which, according to them, was restricted to the mountain regions of Central and East Java. I have dis- covered, that var. montanum is a good species, not only differing by the persistent indumentum of the fruit, but also by the shape of the fruit and the leaves and that the species also occurs in W. Java and goes as far as Sumbawa Isl. I suspect, that Pt. javanicum Junghuhn is this (there is a specimen of Junghuhn from W. Java in the Bogor Herbarium) and that Pt. blumea- num (which has been broken up by Miquel in Pt. blumeanum proper, based On the specimen from Nagara, Java and Pt. sumatranum- Miquel, based on the Korthals specimen from Sumatra) is the common lowland species on Sumatra, Borneo and Java. P t e r o s p e r m u m c e l e b i c u m Miq. Abundant material of this species (Miquel, 111. Fl. Arch. Ind. 1: 87. 1871) has become available, which makes it certain that Pt. niveum Vidal (Rev. PI. vase. Filip. 67. 1886) falls within the variability. The young leaves are rusty sublanuginose on their lower surface; this tomentum is superposed on a closely adpressed, matted, grey white tomentum; when the former wears off, the latter remains and the leaves look whitish Underneath, 1969] KOSTERMANS: New and Critical Malesian Plants VIII 441 P t e r o s p e r m u m e l o n g a t u m Korth. This (Korthals in Nederl. Kruidk. Arch. 1: 312. 1848) was based on a fruit bearing specimen, collected by Korthals in S.E. Borneo near Ban- djarmasin (Banjermassing) along the river. The description is very poor, but the type specimen (of which a frag- ment is in Bogor) makes it possible to place the species as a very common one in Borneo and Sumatra.
