17), and in these specimens the lamelle are only one cell high. 
The Chinese specimens have an entire margin to the leaf-base, the 
capsule is smooth, and the lamell in section are composed of two 
cells. In examples, however, from Sumatra, Philippines, &c., the 
same characters occur as in the Chinese plant; and ina form from 
Sumatra we find leaves with an entire base, yet with lamelle 
only one cell high. Lindberg (Observat. de form. pres. europ.

In examining these Chinese specimens of P. aloides, I was 
surprised to find that the terminal cell of the lamell: (as seen in 
transverse section) was grooved. In European examples of the 
species the terminal cell is, as is well known, similar in shape and 
size to the other cells of the lamella. In specimens from India, 
however, where the species appears to be not uncommon, the 
terminal cell nearly always shows a slight depression in the centre, 
although this peculiarity is not so strongly marked as in Chinese 
and Japanese examples, In Japan we have a supposed endemic 
species of Lindberg’s, P. inflexum, which is very closely allied to, 
if, indeed, it is distinct from, this form of P. aloides with 
the grooved lamella. P. nipponense, Schimp. MSS. in Herb. 
(Yokoska, Nippon, Savatier, 1878), and also P. Oldhami, Schimp. 
MSS. in Herb. Kew (*Japonia, Nagasaka (Oldham) Hooker, 
153”) belong to the same form of P. aloides. P. yunnanense, 
Besch. (17. p. 69), which is described as with “Jamellis in 
sectione transversali margine bifidis," seems from the description 
very close to this Asiatic form of P. aloides.
