it. The pale colour is probably due to the little light 
that can penetrate to the deep chasms between the rocks 
in which it grows. Measured across the leaves, the diame- 
ter is the same throughout, from the base of the plant 
outwards, and the rachises are all of the same size and 
strength.

2. Selaginella dendricola, Jenman, Gard. Chron. vol. 2, 1887. — 
Fronds prostrate, few to several inches long, consisting of a slender 
thread-like rachis and short, distant, usually simple or casually forked 
branches, \-\ in. 1. Leaves extending to the base of the primary rachis ; 
major ones \-\ li. each way, hardly pointed, the base subequally 
slightly cordate, nearly orbicular, horizontal, all except the outer ones 
more or less apart or distant ; the latter contiguous or imbricated, and 
becoming gradually oblong in shape ; minor leaves very minute, ascend- 
ing, distant, ovate, acute. Spikes often crowded at the end of the 
frond, \-\\ in. 1., 4-gonal ; bracts sharply keeled, acuminate, and finely 
denticulate. 
Jenman, n. 2323. Gathered on decaying logs in 
the forest opposite Bartica, Essequibo River, growing 
among, and often more or less concealed in, moss. It is a 
slender delicate species, apparently nearest S. rotundi- 
folia } Spring, and S. minima, Spring. It has a curious 
duplex habit, the long main rachis having lax or distant 
leaves, which are nearly round, while the short branches 
and apex of the frond, which are fertile at the ends, 
have close or crowded oblong leaves. At the top of 
the frond the spikes are peculiarly long, a dozen often 
extending forward side by side ; those of the distant 
lateral branches are shorter. The colour is a very pale 
green. 
General distribution — Endemic.
