LYCOPODIACE.E. 4u 



1. M. polycarpa, Hook., Grev. Leaflets broadly cuneiform, glabrescent; concepta- 

 cula numerous, petiolar, one-sided above the base of the petiole, nodding, ovoid, blunt, about 

 as long as their pedicels.— Hook. Grev. t. 160.— M.brasiliensis, Mart. {Crypt. Bras. t. 73) : 

 our form, which is smaller than the original one of Hook. Grev., with the conceptacula less 

 numerous (8-3), and densely pilose, when young : by their small size (1'" long) the fruits are 

 very different from those of M. quadrifolia. — Hab. Jamaica !, Pd., in ponds, S. Eliza- 

 beth ; [Guiana, Bahia]. 



CL. LYCOPODIACE.E. 



Sporangia and antheridangia both axillary or doubtful organs of fructification (called 

 sporangia) analogous to the antheridangia in structure and axillary insertion. — Stem leafy ; 

 leaves small, moss-like, sessile. 



1. SELAG1NELLA, P. B. 



Sporangia 1-celled, 2-4-valved, 4(-8-])-sporous. Antheridangia 1-celled, 2-vaIved. — 

 Leaves in the West Indian species 4>-stichous, sterile of two kinds, the larger in two lateral, 

 the smaller or middle ones in two anterior series ; spores much larger than the anlheridia. 



* Stem continuous. 



1. S. patula, Spring. Stein creeping, shortly branched, continuous; leaves ovate- 

 ohlong, pointed, ciliate, middle ones subulate; amenta short: bracts conform, 4-sticbous, 

 acuminate, — Lycopodium, Sw. S. sarmentosa, A. Br. S. cordifolia, Spring ■. a form with 

 mucronate leaves. — Leaves V" long. — Hab. Jamaica!, all coll., in woods ; [Cuba!, Wr. 

 940, to Brazil !]. 



2. S. serpens, Spring. Stem creeping, shortly branched, continuous ; leaves oval- 

 oblong, Hunt, ciliate, those of the branchlets imbricate, middle ones mucronate ; aments 

 short : bracts conform, 4-stichous, acuminate. — Lycopodium, W. — Leaves i"'—f" long. — 

 Hab. Jamaica (Spring), in mountain-woods; [Cuba!, Wr. 941]. 



3. S. confusa, Spring! Stem creeping, spreading-branched, continuous; leaves ovate, 

 minutely mucronate at the rounded apex, ciliate (or subentire), most distant, middle oues 

 mucronate; aments short: bracts conform, 4-stichous, cuspidate. — Lycopodium ornithopo- 

 dioides, Sw. (non L.) : [S. ornithopodioides (Lycopodium, L. ; S. integerrima, Spring) is 

 very similar, but has distichous aments]. S. rotundifolia, Spring ! S. denudata, Spring : 

 probably a form devoid of marginal bristles ; at least there is a remarkable confusion in 

 Spring's monograph, as Willdenow says (Sp. PL 5. p. 36) that he separated hisZ. denuda- 

 tum and his L. Itispidum from one and the same Jamaica plant, both growing intermingled ; 

 while Spring has quoted the former of these original specimens as a Jamaica species (Mo- 

 nogr. p. 85), the other as his East Indian S. ornithopodioides (p. 94) ; hence I conclude 

 that L. hispidum, W. (L. ornithopodioides jamaicense, sec. W.), is the ciliate, and L. de- 

 nudalum, W., the eciliate form of S. confusa— Leaves I '"-l'"long. — Hab. Jamaica ! (.V. con- 

 fusa, Spring!); S. Vincent;, Guild. (S. rotundifolia, Spring!); [Cuba!, Wr. 942; Porto- 

 n'co !; Venezuela !, Fendl. 462 , Brazil !]. 



4. S. flexuosa, Spring ! Stem ascending, many -branched, continuous ; leaves ob- 

 liquely oval-oblong, blunt or bluntish, entire, eciliate : base of the rib approximate to the 

 lower margin : middle leaves ovate, awned-cuspidate : bracts conform, 4-stichous, spreading, 

 pointed.— Plum. Fil. f. 43, inf. dertr. Raddi, Fil. Bras. t. 2.— S. didymostscbya, Spring ! 

 Lycopodium stoloniferum, Raddi {non Sic.). L. denudatum, Hook. Grev. sec. Spring.— 

 Laves V'-\\<» long.— Hab. Jamaica!, Macf., Wiles; [Brazil!]. 



5. S. substipitata, Spring. Stem ascending, many-branched, continuous ; leaves ob- 

 liquely ovate, pointed, minutely serrulate, eciliate : base upward produced : middle leaves 

 ovate, awned-cuspidate; bracts conform, 4-stichous, acuminate.— Habit of the preceding and 

 of -ST. Martensii, Spring.— Leaves 1"'-1£'" long.— Hab. Dominica !, Imr. ; [Portorico !; 

 Guadeloupe!; Panama! to Brazil ! and Peru !]. 



6. S. cuspidata, Lk. Stem ctrspitosc, ascending or erect, usually densely branched 

 above, continuous; leaves ovate (or ovate-oblong), cuspidate at the falcate summit, mi-
