base, those of the rachises a little apart, of the final branches close but 
not imbricating. Minor leaves ovate, cuspidate, somewhat keeled, and 
partly overlapping, ^--i li. 1., less w., the margins spinulose-ciliate. Spikes 
square, copious, often crowded round the frond, }-i in. 1. ; bra£ts 
densely imbricated, not or little spreading. 
APPUN, n. 196 and 198; DRAKE; JENMAN, 783 and 
1483. A very common species, growing by the banks of 
rivers and in damp places often submerged, forming 
dense patches or beds. The lateral leaves are rather 
broad, oblong or ovate-oblong, spreading horizontally. 
The intermediate ones are freely cuspidate with spinu- 
lose margins. I have gathered it on the banks of most 
of the rivers of the colony that I have visited. 
General distribution — Northern Guiana to the Brasils. 
8. Selaginellaguyanensis, Spring, Mon. Lycop. II. 134. Baker, Syn. 
Gen. Selaginella, p. 34.— Stems decumbent, above a foot long, sub- 
terete, copiously pinnate, the branches but little compound, Major 
leaves spreading, linear-oblong, middle sized, sub-obtuse, three times as 
long as broad, nearly equilateral, serrulate, subcordate, and shortly 
ciliate on the upper side at the base. Minor leaves very small, cordate- 
ovate, with a large cusp. Spikes square, \ in. 1. ; bra&s ovate, cuspidate % 
strongly keeled.

General distribution — Endemic. 
9. Selaginella Breynii, Spring, Mon. Lycop. II, 119. Baker Syn # 
Gen, Selaginella, p. 23. — Fronds prostrate, with long straight roots at 
intervals beneath, i-i£ ft. 1. dark-green, herbaceous, oblong, with two or 
three frond-like divisions often springing from a common base the 
same shape and size, branched alternately throughout, the primary 
rachis stiffish. Branches contiguous but not close, 2-3 in. 1. with 
shorter alternate branches. Major leaves spreading horizontally, linear- 
oblong, close or imbricating, inequilateral, the upper base auricled and 
deeper than the lower, overlapping, and very faintly pubescent, conceal- 
ing the rachis beneath, 2-2^ li. 1. f li. w. the point sub-acute. Minor 
leaves, ovate, cuspidate, the margin finely serrate, inequilateral,
