CRYPT0GAM1A LYCOFODIACEJE 589 



<?f ect, or decumbent), branching,— the branches 1 to 3 or 4 inches long, erect, or 

 ascending, terete, or slightly angular, flexuose, clothed with a few scattered sub- 

 ulate-lanceolate appressed leaves, the summit of the branches somewhat pedately 

 divided, and dichotomously subdivided, into numerous spreading flatted branchlets, 

 with winged margins which are cut into acute segments resembling distichous or 

 bifarious leaves ; and on the upper and lower superficies of these branchlets is a 

 row of subulate appressed leaves,— thus making the leaves in reality quadrifarious 

 or 4- rowed. Peduncles 4 to 6 inches long, slender, terete, with a few remote subu- 

 late 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 orbicular-ovate, acuminate, 

 with a membranaceous undulate-serrulate margin. 



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



Obs. The trailing variety of this is often collected, as an ornamental evergreen, 

 and hung in festoons round looking-glasses, pictures, &c. in country parlours. 



f \ Spikes sessile. * Leaves scattered. 



3. L. DExnnoii)EU>r, J\fx. Stem erect; branches alternate, crowded 

 near the summit, erect, dichotomous ; leaves somewhat 6-rowed, linear- 

 lanceolate, equal, spreading; spikes terminal, sessile. Heck, Bot. 

 p. 460. 



Tree-like Lycopodiux. Yulgo — Ground Pine. 



Plant smooth. Stem 6 to 9 inches high, erect, or ascending, terete, flexuose, 

 clothed with lance-linear acute leaves, branched and bushy near the summit, the 

 branches dichotomously subdivided, slender. Leaves (on the branches) somewhat 

 4-rowed, about 2 lines long, obliquely subulate-linear, or slightly falcate, acute, 

 spreading, shining green. Spikes mostly several (1 or 2 to 5 or 6), about 2 inches 

 long, terete, and a little tapering to the summit, sessile on the terminal branches ; 

 scales ovate, acute, or acuminate, with a membranaceous margin. 



Hab. Woodlands, and shady thickets: frequent. Fr. July. 



4. L. nu pestrk, L. Stem creeping, with ascending subdivided 

 branches ; leaves scattered, imbricated, linear-lanceolate, capillaceously 

 acuminate, ciliate on the margin ; spikes terminal, sessile. Beck, Bot. 

 p. 461. 



Rock Ltcopodium. 



Stem 1 to 3 inches long, creeping and much subdivided, with the branches short 

 (half an inch to an inch long), and ascending, terete, clothed with imbricated sub- 

 ulatC'lincar greyish-green leaves, which are scrrulate-ciliate on the margin, and 

 terminating in a cinereous membranaceous hair-like point (forming a bluish- 

 white pencil-like tuft at the summit of the branches). Spikes 1 third to half an 

 inch long, somewhat 4-angled, sessile and terminal on the branches, apparently 

 forming a prolongation of them ; scales ovate-lanceolate, capillaceously acumin- 

 ate, scrrulate-ciliate, somewhat keeled, or concave ; capsules orange-yellow. 



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



Obs. Collected by D. Townsend, Esq. 



* * Leaves bifarious. 



5. L. apodux, L. Stem branching, radicating near the base ; leaves 

 2-rowed, alternate, amplexicaul, obliquely ovate, acute, membranous, 

 with smaller acuminate superficial ones; spikes terminal, sessile. Beck, 

 Bot. p. 461.
