A SYNOPSIS OF THE GENUS SELAGINELLA. 179 



271. S. Ottonis, u. sjd. — Sterns slender, entirely trailing, 

 2-3 in. long, distantly pinnate, some of the short branches with 

 3-4 erecto-patent brauchlets. Leaves of the lower plane close and 

 ascending on the branches, rather spaced and spreading on the 

 main stem, oblique ovate, acute, J lin. long, pale green, mem- 

 branous, ciliated all down the upper edge, very cordate, and much 

 imbricated over the stem on the upper side at the base ; leaves of 

 the upper plane half as long, broad ovate, cuspidate, shortly 

 ciliated. Spikes short, resupinate, f lin. diam. ; bracts of the 

 lower plane oblique ovate-lanceolate, erecto-patent ; of the upper 

 plane ovate-cuspidate, yellowish, ascending, strongly ciliated. 



Hab. Cuba, Otto 281 ! 



272. S. consimilis, n. sp. — Stems very slender, trailing, 

 interniatted, 8-4 in. long, distantly pinnate, the branches short 

 and simple. Leaves of the lower plane spaced, spreading, oblong- 

 lanceolate, acute, a line long, pale green, very thin, nearly equal- 

 sided, obscurely ciliated on both sides at the base, broadly rounded 

 on the upper, and scarcely at all imbricated over the stem ; leaves 

 of the upper plane half as long, ovate-lanceolate, acuminate. Spikes 

 short, copious, resupinate, ^ in. diam. ; bracts slightly dimorphic, 

 those of the upper plane ovate-lanceolate, acuminate, erecto-patent, 

 a line long ; those of the lower plane smaller, paler, more 

 ascending. 



Hab. Cuba, Wruiht 8907 ! General habit very like that of S. 

 (ipus and bfasiliensis. 



273. S. coRDiFOLiA Spring Mon. ii. 103. — S. curdata Klotzsch. 

 — Lycopodiiun cordifolium Desv. — General habit and branching of 

 S. serpens, the trailing ^tem reaching a foot long, the short branches 

 often excurrent and whip-like at the tip, the lower copiously com- 

 pound. Leaves of the lower plane contiguous on the branches, 

 spaced on the main stem, ovate-lanceolate, very acute, pale green, 

 membranous, above a line long, ciliated on the upper edge, dilated 

 and subcordate, and imbricated over the stem on the upper side at 

 the base ; leaves of the upper plane much smaller, ovate lanceolate, 

 cuspidate. Spikes very short, resupinate, with dimorphous bracts. 



Hab, San Domingo and Porto Eico. I have not seen this, 

 and place it amongst the platystachyoid species on A. Braun's 

 authority. 



Group III. — Brachystachy.e . 



274. S. BRACHYSTACHYA Spring Mou. ii. 255. — Lycopodium bra- 

 chystachijum Hook. & Grev. — Stems reaching a foot or more in 

 length, generally assurgent from a decumbent base, bisulcate down 

 the face, copiously compound, the final branching midway between 

 pinnate and flabellate. Leaves of the lower plane contiguous on 

 the branchlets, spaced on the main stem, spreading or rather 

 ascending, oblong-rhomboid, obtuse, one-sixth to one-fifth in. long, 

 dilated on the upper side at the base, cordate, not ciliated, much 

 imbricated over the stem ; leaves of the upper plane small, ovate, 

 with a cusp as long as the lamina. Spikes resupinate, |— |- in. 

 long, ^ in. diam. ; bracts of the upper plane oblique lanceolate, 

 erecto-patent ; of the lower plane ovate-lanceolate, ascending,
