Lycopodiace^e of Guiana and their Allies. 37 
North America Selaginellas are largely cultivated as 
decorative and ornamental plants in Fern houses. Their 
habit of growth enables gardeners to propagate the great 
majority of them rapidly and with ease by subdivision. 
This is the only use to which they are turned or which 
they are known to possess. All except three or four 
species have a very limited geographical range, and 
according to Mr. BAKER only three species are common 
to both the Old and New Worlds. Two-thirds of the 
species here described are confined to Guiana, so far as is 
at present known ; the rest extend only to Brazil and 
some of the nearly adjoining countries. 
§ Leaves of two kinds, major and minor. Spikes 4-gonal ; bracts 
uniform. — Species 1-22. 
t Fronds prostrate. — Species 1-9. 
* Species not exceeding a line wide across rachis and leaves, — 
Species 1-4. 
1. Selaginella valdepilosa, Baker, Syn. Gen. Selaginella, p. 11. 
— Fronds delicate, pale green, quite prostrate, very slender ; linear and 
repent, simple or with few short branches, 1 li. w. over the leaves, ter- 
minating in a depauperated tail, having only small leaves, in shape 
like the minor series. Major leaves spreading, not quite horizontally, 
ovate, acute, subequilateral, the margin freely ciliated, most so on the 
uppei side, J li. 1., less w., with half their own width between them. 
Minor leaves also ovate, equilateral or nearly so, acute, but not spinu- 
lose pointed, hardly i li. 1. and less wide, both margins pubescent. 
Spikes a line or over 1. ; bra£ts keeled. 
JENMAN, n. 1484. Gathered in the deep ravines in 
the forest near the top of the Kaieteur Fall. Marked by 
its little branched, very narrow, linear fronds, which are 
1-1^ in. 1., terminating in a depauperated tail. The 
colour is exceedingly pale. The under side looks very 
pubescent, from the long marginal hairs of the rather 
au ricled upper base of the lateral leaves which overspread
