LYCOPODIACEiE OF GUIANA AND THEIR ALLIES. 41 
6. Selaginella potaroensis, Jenman, Gard. Chron. vol. 2, 1887. — 
Fronds quite prostrate, with delicate filiform roots at the joints, 2-4 
in. long, with short distant alternate branches, which are simple or 
again shortly branched, flaccid and delicate. Rachises very slender, 
and thread-like, brightly stramineous, leafy to the base, 2-2^ li. w 
over all. Major leaves spreading, distant, becoming gradually conti- 
guous, but not touching, on the outer parts ; obliquely ovate, broadly 
acute, obliquely cordate, but narrowed at the base, the superior base 
very slightly auricled, i£ li. 1., f li. b., the margin plain ; colour light 
straw green. Minor leaves much reduced, distant, situated at the base 
of the major, inequilateral, attached by the inner side of the base 
obliquely ovate, cuspidate, about i li. 1. Bra6ls ovate-lanceolate, 
imbricating but slightly open. 
JENMAN, n. 1818. Gathered in ravines in the forest near 
the Kaieteur Fall. A species well marked by its bright 
straw colour, very slender, conspicuous, yellow rachises, 
distant, ovate, lateral leaves, which seem at sight, though 
they are not really, narrow T ed equally each way, and very 
minute medial ones. The latter are so small that they 
can only be seen by the aid of a lens. When a frond is 
looked at on the under side with a lens they are seen 
proje6ling like a small auricle against the inferior base ot 
the major leaves. In the longer spikes, some of which 
are nearly half-an-inch long, the brafts are imbricated 
moderately firmly ; but in the shorter ones, a line or so 
long, they are lax, and seem, as is often the case in that 
state, somewhat disposed to be, but are not, resupinate. 
General distribution— Endemic. 
7. Selaginella producta, Baker, Syn. Gen. Selaginella, p. 33. — 
Fronds prostrate or subere6t, rooting at the base, and on the stem at 
intervals as well, an inch or two to a foot 1., oblong, lanceolate or ovate, 
with contiguous, nearly uniform, ere£t-spreading branches, 1-2 or 3 in. 
1. Major leaves oblong, spreading horizontally, deeper and auricled on 
the upper side at the base, the lobe overlapping the rachis beneath, 
\-\\ li. 1., \ li. or over w., very faintly spinulose-ciliate on the rounded
