LYCOPODlACEiE OF GUIANA AND THEtR ALLIES. 45 
probably supports its slender fronds on other vegetation. 
The branches are rather distant, always short in relation 
to the length of the fronds, varying from 1-3 in. 1. The 
habit of growth is probably that of S. puberula. 
General distribution — Guiana and Central Brazil. 
ft Fronds sub-prostate, — Species 10-18. 
* Rachises not exceeding i\ lines wide over the leaves. — Species 
10-13. 
13. Selaginella flagellata, Spring, Mon. Lycop II. 208, Baker, 
Syn. Gen. Selaginella. — Fronds trailing, intermatted, half-a-foot long, the 
lower parts copiously compound, the branches excurrent and whip-like 
at the end. Major leaves ovate-lanceolate^ very acute, above a line long, 
pellucid, bright green, more produced on the upper side of tbe mid-rib, 
rounded at the base, shortly ciliated, and imbricated over the stem. 
Minor leaves one-third as long, ovate-acuminate, falcate, convergent. 
Spikes i-i in. long, bracks very acuminate, strongly keeled.

of the Upper Oyapok ; LEPRIEUR. This I have not seen, 
and have quoted from Mr. Baker's Synopsis. 
General distribution — Endemic. 
** Rachises 2^-3 lines wide over the leaves, — Species 14-15. 
14. Selaginella caudorhiza, Baker, Syn, Gen. Selaginella, p. 36. 
— Fronds, rooted at the base, 8-18 or more in. 1. ovate, with contiguous 
pinnae in the lower part, but extending above into a lax narrower state, 
having short distant branches, the lower of which (not lowest which are 
less) 2-5 in. 1., ere&o -spreading, repeatedly pinnate. Major leaves of 
main rachises spreading, about 1 i li. 1. $ li. w. acutely pointed, rounded 
and nearly equal-sided at the base, with once to twice their own width 
between them. Minor leaves cuspidate, attached obliquely, the mar- 
gins very faintly ciliate. Leaves of the branches the same shape but 
only half the size, close but not imbricating. Spikes 2-3 li. 1. ; bra6ts 
keeled, somewhat spreading 
Surinam only, collefted by HOSTMAN, in 1841. The 
growth seems to be sub-ere6l, as there are no roots along 
the frond between the base and the outer elongated part,
