120 A SYNOPSIS OF THE GENUS SELAGINELLA. 



246. S. ANCEPs A. Br. in Fil. Nov. Gran. 362. — .S'. Spnicei 

 A. Br., loc. cit. — S. flahellata Spring, ex parte. — Lycopodiwn anceps 

 Presl. — Stems 1-2 ft. long, erect, stramineous, simple in the lower 

 half, with entirely adpressed leaves, deltoid and 2-3-pinnate in the 

 upper half, the contiguous erecto-patent ultimate segments reaching 

 2-3 in. long, \-^ in. broad. Leaves of the lower plane crowded, 

 ascending, lanceolate-rhomboid, acute, ^-^ in. long, bright green, 

 moderately firm in texture, dilated, cordate, shortly ciliated, and 

 nmch imbricated over the stem on the upper side at the base ; 

 leaves of the upper plane one-third as long, oblique ovate, acute. 

 Spikes square, reaching 1-1|- in. long, 1 lin. diam. ; bracts ovate- 

 lanceolate, strongly keeled. 



Hab. Andes of Venezuela, New Granada, Ecuador, and Peru. 

 Habit less compound than in jlahcUata , and leaves much larger. 



Series VI. — Caulescentes. 

 Group 2. — Geniculatje. 



247. S. Parkeri Spring Mon. ii. 226. — S. hicidinervia Spring. 

 — Lj/copodiuin Parkeri Hook. & Grev. — L. plumosum Aublet ! — 

 Stems 1-lf ft. long, simple in the lower half or two-thirds, 

 articulated, stramineous, distinctly articulated, deltoid and decom- 

 pound in the upper part, with petioled bipinnate deltoid lower 

 piunfe, long lanceolate penultimate divisions with a flexuose rachis, 

 and contiguous erecto-patent final divisions 4—1 in. long, \-\ in. 

 broad. Leaves of the lower plane contiguous, lanceolate-rhomboid, 

 ascending, pointed at the upper corner, ^-\ in. long, bright green, 

 moderately firm in texture, auricled on both sides of the narrow 

 base, unequal-sided, broadly rounded on the upper side at the base, 

 and a little imbricated over the stem ; leaves of the upper plane 

 one-third to one-quarter as long, lanceolate, acute. Spikes short, 

 square, 1 lin. diam. ; bracts ovate-cuspidate, acutely keeled. 



Var. 8. pedata Klotzsch in Linnfea xviii. 521. — S. nodosa 

 Kunze. — Branched portion of the stem more compound, with 

 narrower divisions, shorter leaves of the lower plane, and longer 

 more slender spikes. 



Var. N. steUata Spring Mon. ii. 228. — S. calcarata A. Br. in 

 Crypt. Nov. Gran. 389. — UiDper part of stem copiously compound, 

 lengthened out, and taking root at the tip. 



Var. iS'. Vaiilieurchidna Spring. — S. frcujilis K.ljv.m Crypt. Nov. 

 Gran. 389. — Stems slender and trailing, bipinnate above the 

 simple base, gradually lengthened out upwards with a long whip- 

 like radicant end. 



Hab. Guiana and the Amazon Valley. This is probably the 

 " planta muscosa et plumosa guayanensis perelegans minor" of 

 Breynius Ic. t. 101, cited by Linua^us under his L. jdiiniusuiii. 



248. S. ASPERtTLA Spring Mon. ii. 225. — Li/co]iodiuin a.spenilum 

 Mart. — Stems about a foot long, erect, articulated, stramineous, 

 simple in the lower half with adpressed leaves, compound in the 

 upper half with broad erecto-patent pinn?e 2-4 in. long, with 

 distant sparingly sn1)flube]lately compound erecto-patent pinnules.
