again expressed with regard to the genus. Subsequent comparison of a fragment 
of the later species with Weddell’s type, by Professor Lecomte of the Museum 
d’Histoire Naturelle, Paris, left no doubt of their identity. The first collection 
from Borneo also had pistillate inflorescences, identical with the Philippine, and 
I am greatly indebted to Mr. J. C. Moulton, of the Sarawak Museum, for a large 
quantity of material with inflorescences of both kinds. 
At first sight and even under the lens, no pistillate perianth can be seen : under 
the compound microscope it appears as a single row of cells, closely adhering to 
the achene except in some cases at the apex and still less frequently at the base. 
The inflorescence has already been fully described, it suggests that of Sarcochlamys 
and the minute flowers have much of the aspect of those of that genus, which is 
its nearest alliance; however, the perianth differs. The staminate inflorescences 
show a tendency in the same direction as the pistillate, but do not form a 
receptacle; the flowers are tetramerous, not a character of either Maoutia or 
Sarcochlamys, and the rudimentary ovary is not concealed by the woolly indu- 
mentum of the perianth ; these are matters of secondary importance. In these 
rudimentary ovaries, the gelatinous perianth is quite distinct. One receptacle, 
otherwise pistillate, has a single lobe staminate.

Dr. F. Gagnepain of the Museum d’Histoire Naturelle, has kindly compared 
Bur. Sci. 8289 with the type of M. setosa, Gallery 30, also from the mountains of 
Pangasinan, and finds it a perfect match, and has further indicated the differences 
between it and the type of iff. platystigma, also in their herbarium. Upon 
careful study of the series of specimens now at hand, there seems no good 
character left upon which to maintain a separation. If that were done, the 
Banajao and Batangas collections would be the only ones under iff. platystigma, 
for their leaves are usually widest near the middle, the stipules are less pubescent, 
and the tomentum of the under surface of the leaves less snowy. Leaf-texture 
does not assist, for the Banajao leaves are nearly coriaceous, and those of Bur. 
Sci. 5340 are membranaceous, whereas these collections otherwise exhibit the 
reverse alliance. But on several collections, leaves are present, some of which 
are widest near the base, and others about the middle or even above the middle. 
This is especially true of the two southern collections. The character drawn 
from the stigma is also unreliable. In one way, the Apo plant is the most 
distinct of all, having wider stipules.
