LYCOPODIACEAE 401 



branches 1 to 4 or 5 inches long, alternate, often subdivided, very leafy. Leaves 

 3 to 5 lines in length, pale green, incurved-spreading, subulate-linear, with a long 

 hair-like point, forming a hairy tuft at the summit of the branches. Spikes (some- 

 times 1 rarely 3,) % an inch to nearly an inch in length, yellowish, erect on an 

 ascending leafy branch-like peduncle 2 to 4 inches long ; scales ovate, setaceously 

 acuminate. 

 Hob. Woodlands, and thickets : frequent. Fr. July. 



** Leaves of 2 farms and unequal, few^ranked; stems or branches flattened. 



5. I*, complanatum, L. Stems trailing extensively ; brandies 

 ascending, dichotomously and pedately subdivided, spreading and 

 fan-like; spikes several. 

 FLATTED LYCOPODIUM. 



Stem 2 to 6 or 8 feet long, rather slender, somewhat leafy, procumbent (some- 

 times rhizoma-likc, and more or less buried) ; branches 1 to 3 or 4 inches long, 

 erect or ascending, yellowish-green, somewhat pedately divided at summit, and 

 these divisions dichotomously subdivided into numerous spreading flatted branchlets 

 with winged serrated margins. Peduncles 4 to 6 inches long, slender, terete, with 

 a few remote subulate leaves, dichotomously subdivided at summit 2 or 3 times, 

 so as to bear 4 to 8 pedicellate spikes each about an inch in length; scales orbicu- 

 lar-ovate, acuminate. 

 Hob. Borders of woods, and thickets : frequent. Fr. Octo. 



Obs. My friend, JOSHUA HOOPES, finds specimens on our slaty 

 hills, which he regards as almost specifically distinct, having the 

 trailing stems mostly buried and rhizoma-like, the branches of a 

 brighter green, the ultimate branchlets not so coarse, and twice as 

 numerous, while the spores are matured 2 or 3 months earlier than 

 on the common form. 



526. SEL,AGIffEL/L,A, Beauvois. 



[Diminutive of Selago, an ancient name of Lycopodium.] 

 Sporanges of two kinds, one, like those of Lycopodium, but very 

 minute and oblong, or globular, containing powdery orange-colored 

 spores, the other, of 3- or 4-valved tumid vesicles (by way of dis- 

 tinction, termed sporocarps,) filled by a few much larger globose- 

 angular spores ; these latter either intermixed with the former in 

 the same axils, or solitary in the lower axils of the leafy, 4-ranked, 

 sessile spike. 



f Leaves all alike, equally imbricated. 



1. S. rupestris, Spring. Stem creeping ; branches ascending, 



rather rigid ; leaves subulate, bristle-tipt, densely appressed-imbri- 



cated, greyish-green. 



Lycopodium rupestre. L. ^ Fl. Cestr. ed. 2. p. 589. 



ROCK SELAGINELLA. 



Stem \ to 3 inches long, much subdivided ; branches % an inch to an inch long, 

 ascending, terete. Leaves serrulate-ciliate, their membranaceous hair-like points 

 forming a bluish-white pencil-tuft at the summit of the branches. Spikes % to 

 half an inch long, somewhat 4-angled, sessile and terminal on the branches ; 

 scales ovate-lanceolate. 



Hab. Rocky banks ; Chester Creek : not common. Fr. July.
