LYCOPODIACE^. 645 



1. n, polycarpa, jBbc^., Grev. Leaflets broadly cuneiform, glabrescent; coneepta- 

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

 as long as their pedicels.— fiboA. Grev. t. 160.— M.brasiliensia, Mart. {Crypt. Bras. t. 78) : 

 our form, which is smaller than the original oue of Hook. Grev., with the conceptaoula less 

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

 very different from those of M. guaclrifolm.—UA.B. Jamaica !, Pd., in ponds, S. Eliza- 

 beth; [Guiana, Bahia]. 



CL. LYCOPODIACEiE. 



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

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

 leaves small, moss-like, sessile. 



1. SELAGINELLA, P. B. 



^orangia l-celledj 2-4-valved, 4(-8-l)-sporous. Antheridangia 1-celled, 2-valved.-j 

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

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

1. S. patnla, Spring. Stem creeping, shortly branched, continuous; leaves ovate- 

 ohlong, pointed, ciliate, middle ones subulate ; aments short : bracts conform, 4-stichous, 

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

 mucronate leaves. — ^Leaves 1'" long. — Has. Jamaica!, all coU., in woods ; [Cubal, Wr.

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

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

8. S. confusa, iS^m^ .' j^^era cre^zn^, spreading-branched, continuous ; leaves ovate, 

 minutely mucronate at the rounded apex, ciliate (or subentire), most distunt, middle ones 

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

 dioides, iS». {fion Z.) : [S. omithopodioides (Lycopodium, L. ; S. integerriraa. Spring) is 

 very similar, but has distichous aments]. S. rotundifolia, ;^ri»^/ S. denudata, iSjoWm^ ; 

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

 Spring's monograph, as Willdenow says (Sp. PI. 5. p. 86) that be separated his-t. denuda- 

 tum and his L. hispidum 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. omithopodioides (p. 94) ; hence I conclude 

 that L. hispidum, W. {L. omithopodioides jamaicense, sec. W.), is the ciliate, and L. de- 

 nudatum, W., the eciUate form of & confusa. — Leaves i"'-l"'long. — Has. Jamaica ! {S. con-
