Species 20-21. 
20. Selaginella H^nkeana, Spring, Mon. Lycop. p. 187. Baker, 
Gen. Selaginella, p. 76.— Stems ere6t, strong, angular clothed with 
scattered leaves. Fronds erect, regularly pinnate or flabellate, 5-8 in. 
each way, firm, dark green above, silvery beneath. Pinnae numerous, 
much branched and crowded, so that the habit is often plumose in 
growth ; rachises 3-4 li. w. over all. Final branches 1^-2 li. b. 
Leaves of the former apart, of the latter close, spreading obliquely, 
oblong, acute, the base cordate and rather auricled, the rounded and 
upper side ciliate, the larger 1^-2 li. 1. and f-i li. w. the smaller half 
that size. Minor leaves minute, ovate, terminating in a hair-like awn, 
rather inequilateral, the margins faintly serrate. Spikes very small, a 
li. 1. with small, laxly spreading, bracts which are hardly keeled. 
Cayenne, gathered by LEPRIEUR and SAGOT. Well 
marked by the much-branched, crowded habit. Mature 
fronds when pressed have the parts lying one over the 
other. The beautiful silvery underside, and very short 
loose spikes in which the brafts are hardly changed in 
charafter from the intermediary leaves, and the sporangia 
are fully exposed, are also good distinguishing characters. 
It resembles most in the outline of the fronds the next 
species.

Syn. Gen. Selaginella, p. 79. S. lucidinerva, Spring. Lycopodium 
Parkeri, Hook et Grev. L. plumosum, Aublet. — Stems strong, quite 
erect sub-angular, or quadrate upwards, stramineous, jointed at inter- 
vals, sparsely furnished with appressed leaves, and spreading by' sto- 
loniferous shoots which spring from the joints and trail on the ground 
or ascend banks, rocks, or the base of trees, 6 in.-i ft. or over 1. Fronds 
spreading from the top of the stems, digitato-pedate or flabellate, 4.10 in. 
each way, composed of numerous forked, spreading pinnate branches, 
with a flexuose rachis 3-4^ li. w. over all. Major leaves spreading 
horizontally, close, in the final br inches imbricated, oblong, the under
