larger and broader fronds often crowded. Major leaves spreading 
nearly horizontally, the inferior ones contiguous, the outer imbricating, 
i-i£ li. I., i-f li. w., acute, broadened at the base, which is unequally cor- 
date, broadly auricled and overlapping the rachis on the upper side ; the 
margin plain or faintly spinulose. Minor leaves ascending, imbricating, 
ovate-lanceolate, acuminate-cuspidate, finely spinulose-edged. Spikes 
2-8 li. 1. ; bracks in two series, those of the upper side twice as long as the 
under ones, the latter especially spinulose-edged. 
JENMAN, n. 2322. Gathered in wet places in the 
forest opposite Bartica, Essequibo River. Well distin- 
guished from S. platyphylla by its more compound 
and broad-spreading fronds, and smaller closer leaves. 
The leaves are so crowded and imbricated on the outer 
branches (which also are crowded in the larger fronds) 
that on the Herbarium sheets they have quite a spinulose 
aspeft on the upturned underside. It was gathered in 
Cayenne by LEPRIEUR and SAGOT. 
General distribution — Endemic. 
24. Sklaginella platyphylla, Baker, Syn. Gen. Selaginella, p. 95. 
— Fronds prostrate, rooting along the rachis, leafy from the base, 4-6 in. 
1., linear-oblong, 2-pinnately branched, the branches short, sub-distant, 
alternate, longer primary ones \-\\ in. 1., secondary ones \-\ in. 1. 
Rachises weakly, the primary 3 li. w. over the leaves, secondary 2-2^ 
li. w. Major leaves spreading horizontally, from once to twice their 
own width apart on the main rachis, becoming contiguous at the top, 
obliquely ovate-oblong, i£-2 li. 1., $ li. b., obtuse-acute, inequilateral, 
the upper base auricled, broadly rounded and ciliate, quite over- 
lapping the rachis, the margin whitish and scariose. Minor leaves 
alternate, edged like the major, ovate, cuspidate, rather obliquely 
cordate at the base, but nearly equilateral, quite in line with the rachis. 
Spikes very short, lax. Bra&s dimorphous, the larger lanceolate, the 
smaller ovate, hardly keeled, open, revealing the sporangia. 
Var. laxa. — Major leaves more ovate, wider apart throughout, the 
auricled base quite plain. Texture thinner, and rachises slenderer and 
weaker.
