use SALMON: SOME SPECIES OF ECTROPOTHECIUM 
denticulate above ; the cells are lax, and hexagonal in shape. The 
ventral branch-leaves are smaller, and more abruptly acuminate 
from a broadly oblong or subquadrate base ; the cells are more 
delicate, hexagonal in shape, but longer ; the acumen is long and 
fine. Seta about 2 cm. long; capsule pendulous. The habit is 
very Aypnoid (as in other species of Ectropothectum), and in the 
regularly hamate leaves, all turned in one direction (so that the 
dorsal surface of the stem and branches has a smooth or almost 
glossy appearance, while viewed from below the stem and 
especially the branches bristle with the flexuose arcuate points of 
the leaves) the plant recalls sucha species as ypuume cupressiforme. 
Mitten’s type is labeled “120 Hypuum Montagnet Schimp. in 
Mont. Crypt. Cub. p. 530, t. 20. Hab. decayed logs in forests. 
Cuba, Wright, ex parte.” 
In the Kew Herbarium part of the specimens under the wo. 
z20 in Wright’s Cuban Mosses belongs to &. crassicaule Mitt., and 
agrees with the type in every way except that many of the dorsal 
branch-leaves are a little broader, being ovate-acumiate instead of 
lanceolate.
