LYCOFODJACEJ 7 ,. (CLUB-MOSS FAJIILT.) C03 



2. L.. Selago, L. Stems thick and rigid, erect, fork-branched, forming a 

 level topped cluster (3'-6' high) ; leaves spreading, lanceolate, pointed, entire. 

 Tops of high mountains, Maine to New York, on the Alleghanies southward ; 

 also shore of Lake Superior, and northward ; rare : both the variety with more 

 erect, and that with, widely spreading, leaves. (Eu.) 



$ 2. Sporangia borne only in the axils of the upper (bracteal) leaves, thus forming 

 terminal spikes or catkins. 



* Leaves of the creeping sterile and tfie upright fertile stems or branches, and those of 



the simple spike all alike, many-ranked (sporangia opening near tfie base). 



3. Li. imimlatuiii, L. Dwarf; creeping sterile stems forking, flaccid ; 

 the fertile solitary (l'-4 ; high), bearing a short thick spike; leaves lanceolate or 

 lance-awl-shaped, acute, soft, spreading, naked, or sometimes bearing a few minute 

 spiny teeth. Leaves (curving upwards on the prostrate shoots) narrower in the 

 American than in the European plant (perhaps a distinct species), and passing 

 into the var. Bi6EL6vn, Tuckerm. : with fertile stems 5' -V high, its leaves 

 more awl-shaped and pointed, sparser and more upright, often somewhat teeth- 

 bearing. (L. Carolinianum, Bigd., not of L.) Sandy bogs, northward, rare : 

 the var. from New England to New Jersey and southward, near the coast. 

 Aug. (Eu.) 



4. Li. alopecuroides, L. Stems stout, very densely leafy throughout ; 

 the sterile branches recurved-procumbent and creeping ; the fertile of the same 

 thickness, 6' -20' high ; leaves narrowly linear-awl-shaped, spinulose-pointed, spread- 

 ing, conspicuously bristle-toothed below the middle ; those of the cylindrical spike with 

 long setaceous tips. Pine-barren swamps, New Jersey to Virginia, and south- 

 ward. Aug., Sept. Stems, with the dense leaves, ' thick ; the comose spike, 

 with its longer spreading leaves, f ' to 1' thick. 



* # Leaves (bracts) of the catkin-like spike scale-like, imbricated, yellowish, ovate en 



heart-sJiaped, very different from those of Hie sterile stems and branches. 



*- Spikes sessile (branches equally leafy to the top), single. 



5. JL. a !in 6th! U ill, L. Much branched; stems prostrate and creep', >g 

 (l-4 long) ; the ascending brandies similar (5' -8' high), sparingly forked, tho 

 sterile ones making yearly growths from the summit ; leaves equal, spreading, in 

 about 5 ranks, rigid, lanceolate, pointed, minutely serrulate (pale green) ; spike 

 solitary, oblong-cylindrical, thick. Var. PUXGEXS, Spring, is a reduced sul>- 

 alpine or mountain form, with shorter and more rigid-pointed crectish leaves. 

 (Var. montanum, Tuckerm.) Woods; common northward: the var. on the 

 White Mountains, with intermediate forms around the base. July. (Eu.) 



6. L,. dcildroideimi, Michx. (GnousD-PiSE.) Stems upright (6'- 

 9' high) from a subterranean creeping rootstock, simple below, and clothed with 

 homogeneous lanceolate-linear acute entire leaves apprcssed-crcct in 4 - 6 rows, 

 bushy -branched at the summit ; the crowded branches spreading, fan-like, with the 

 lower row of leaves shorter and the lateral spreading, in var. ousctRUM 

 appearing flat, from the leaves of the upper side being also shorter and ap- 

 pressed. (L. obscurum, L.) Moist woods. Aug. Remarkable for its tree- 

 like growth. Spikes cylindrical, 4- 10 on each plant.
