DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 129 
It is no doubt the same plant as Sir Hugh Low’s. As the material is fragmentary, I 
cannot go beyond the suggestion that it is more likely a species of Michelia. 
ANONACE. 
GONIOTHALAMUS DISPERMUS, Miq. (?), Ann. Mus. Lugd. Bat. ii. 34; Scheffer, Ann. 
Jard. Bot. Buit. ii. 25. 
At 3000 feet (Haviland, 1313). 
Distribution: Borneo. 
G. dispermus, so far asit is represented by a specimen of Miquel's in the Kew Herbarium 
and by a specimen collected by Motley (no. 1127) near Banjermassin, resembles very 
much G. malayanus, Hook. fil. & Th., but the flowers are twice or three times as large, 
attaining 2-2; in., and golden yellow, not greenish. The plant from Kinabalu has 
flowers of the same size, shape, and colour; the sepals and the leaves, however, differ 
slightly. 'The former are much less hairy, and the outer ones are, except at the base, 
almost glabrous outside. The difference in the nervation of the leaves is perhaps of 
more importance. The nerves are very faint and, in leaves of equal length, less 
numerous, 9—10 against 16-17 in the typical plant, and the transverse venation, which, 
although very faint, can be distinctly seen in the South Bornean specimens, is almost 
invisible in the Kinabalu plant, even when the leaves are held against the light. 
Besides, the leaves of Haviland's plant are more suddenly contracted into the linear 
blunt acumen. But, taking into consideration the variability of these characters in other 
species which are better known, I doubt whether they are sufficient to separate the 
North and the South Bornean plant specifically, and I the less venture to do so as the 
material at hand consists only of three specimens.
