PINNATELLA МОСВОМАТА (Bry. jav.), Fleisch. Jungle tree, Sapong, near 
Tenom (No. 182). 
P. microprerRA (C. Muell.), Fleisch. Jungle tree, Sapong, near Tenom 
(No. 212 а). A remarkable plant, hitherto only known from the Philippines 
and Singapore. The leaves are dimorphous. small rounded very concave 
and not eomplanate leaves (Brutblütter) taking the place of the normal 
leaves along the upper part and often at the base of many of the branches, 
and readily falling away, so as to leave tle greater part of many of the 
branches denuded and bare.

Slender twigs in low damp place in jungle, Sapong, near Tenom (No. 175). 
A striking and interesting plant, with much the foliation and appearance 
of Orthostichopsis tetragona (Sw.) Broth., of tropical America, as pointed out 
by Mitten. І аё first took the specimen for a Pilotrichella, and found it to 
be identical with a specimen at Kew named “Pilotrichella perakensis, Broth. 
n. sp., Nos. 3550, 3636, Upper Perak, June 1889, leg. J. Wray Jr., Herb. 
Mus. Perak." Оп writing to Dr. Brotherus for permission to publish this 
inedited species, I learnt from him that he had in the meantime obtained 
fertile specimens from the Philippines, showing it to be a Chetomitrium, 
which he had published as C. Elmeri. From Mitten’s description of 
C. bornense (a species referred to by Brotherus in the “ Musci ” as “nicht 
gesehen "), however, I am convinced that this is the same thing. Mitten’s 
description of that species is almost identical with Brotherus' description of 
C. Elmeri, and there are no points of difference indieated ; moreover, the 
identity of Mr. Binstead’s plant with the Perak specimen removes all doubt 
of the plants all being referable to Mitten's species.
