180 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 
fruits agree perfectly with those of the Bornean plant, and, as a comparison with the 
young fruit still attached to the branch proves, they belong doubtless to Teysmann’s 
specimen. But the true Ch. expansa, Miq., or Psychotria expansa, Bl, is a different 
plant with membranaceous leaves and identical with P. montana, Bl. The fruit is 
slightly compressed from the back and hardly furrowed at all. The endosperm is very 
ruminate. A specimen collected by Motley at Banjermassin (608), and probably 
identical with P. crassifolia, Miq., comes also very near, but it has smaller and more 
coriaceous leaves. The inflorescence and the fruits, however, are exactly as in P. 
malayana. 
The Kinabalu specimens represent the microstyle form. The stigmata, which are a 
little narrower and perhaps less papillose than in the macrostyle form, almost reach 
the mouth of the corolla, whilst the filaments surpass the mouth to the extent of ¿-1 lin. 
The anthers are about 1 lin. long. This form is represented also by a part of Zollinger’s 
specimens (173), whilst Teysmann’s and those of Fraser and Motley belong to the 
macrostyle form. Here the style surpasses the mouth by more than 1 lin., whilst 
the anthers, which are also 1 lin. long, just reach the mouth by their tips. The 
filaments are extremely short. The microstyle flowers were observed in inflorescences 
with half-mature berries. The anthers, which in both forms hardly differ, were always 
found to bear apparently quite normal pollen. A curious intermediate state is re- 
presented by another of Zollinger’s specimens, also numbered 173. It is evidently 
macrostyle; but two of the stamens are exserted, 3 included. They, however, do not 
seem to be quite normal. The stigmata are long, linear, and minutely papillose. The 
flowers exhibit another abnormality. The corolla is 4-lobed, apparently by the 
coalescence of two lobes, whilst the androecium is pentamerous. The exserted stamens 
stand one on each side of the double lobe, which is hardly larger than the other lobes, 
whilst a small stamen is opposite to it. The remainder of Zollinger’s specimens is 
pentamerous, like all other specimens I have seen, except those of Fraser's and Motley's 
collection, which are tetramerous.
