transparent. It was originally described from 
material collected on Mt. Tappotyo, on the 
island of Saipan, in the Marianas group. Our 
present specimen, of which living material is. 
being grown in our Botanical Garden, differs 
slightly in dimensions and in the green in- 
stead of white flowers.

In Fedde, Repert. Spec. Nov., Beihefte 1: 
644, 1914. 
Only a single species of this interesting and 
difficult genus is at present known from the 
Carolines. The type material was collected by 
Ledermann near Patapat ( = Potopot) on 
Ponape in 1913; he also obtained additional 
specimens near Paue ( = Poaipoai), on the 
same island. The species is known also from 
Babelthuap in the Palau group. 
Pseuderia micronesiaca Schltr., Engl. Bot. 
Jahrb. 56: 473, 1920. 
Mt. Kubersoh, 2,000 ft. alt.: on mossy 
tree trunks. Flowers pale green with brownish 
spots. This plant is common throughout the 
higher mountains, sometimes almost com- 
pletely covering a whole tree. Base of stem 
always rooted in ground. August, 1950, P. A. 
Adams 20. The species is most closely allied 
with Pseuderia frutex Schltr., of New Guinea. 
STERILE MATERIAL 
Forty-five minutes up trail from Nanpil to 
Tolenkiup: on fallen tree. Abundant in pri- 
mary forest from 1,000 ft. alt. (more or less) 
up. Flower not seen. August, 1950, P. A. 
Adams 8. 
This plant, of which only a very fragmen- 
tary specimen is present in the collection, is 
probably referable to one of the sarcanthad 
genera (subtribe Sarcanthinae) which occur in 
these islands, viz., Chiloschista Ldl., Thrix- 
spermum Lour., Luisia Gaud., Vandopsis Pfit2., 
Trichoglottis BL, Rohiquetia Gaud., Saccolabium 
BL, or Sarcanthus Ldl.
