lycopodiacejE. (club-moss family.) 637 
flexed, linear-lanceolate, acute, minutely toothed. — Cold, damp wood*. 
August. 
2. Is, Selago, L. Stems thick and rigid, erect, fork-branched, 
forming a level-topped cluster (3' -6' high); leaves spreading, lanceo¬ 
late, pointed, entire. — Tops of high mountains, Maine to New York, 
and northward, rare ; both the variety with more erect, and that with 
widely spreading, leaves. 
§ 2. Lycopodium proper.— Sporangia borne only in the axils of the 
upper ( bracteal) leaves, thus forming terminal spikes or catkins. 
* Leaves of the creeping sterile and the upright fertile stems or 
branches, and those of the simple spike all alike , many-ranked ( spo¬ 
rangia opening near the bast). 
3. £,. innndatum, L. Dwarf; creeping sterile stems fork¬ 
ing, flaccid; the fertile solitary (l'-4' high), bearing a short thick 
spike; leaves lanceolate or lance-awl-shaped, acute , soft, spreading, 
nuked, 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. Bigel6vii, Tuckerm.: fertile stems 5'-7' high, its 
leaves more awl-shaped and pointed, sparser and more upright, often 
somewhat teeth-bearing. (L. Carolinianum, Bigel., not of L.) — San¬ 
dy bogs, northward, rare : the var. from New England to New Jersey 
near the coast. Aug. 
4. L,, 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, spimdose-pointed, spreading, conspicuously bristle-toothed 
below the middle ; those of the cylindrical spike with long setaceous lips. 
— Pine-barren swamps, New Jersey and southward. Aug., Sept. — 
Stems, with the dense leaves, thick; the comose spike, with its 
longer spreading leaves, to 1' thick.— Most distinct from the true 
L. inundalum, and I think also from the variety given above, which 
has been confounded with it. 
* * Leaves of the catkin-like spike (bracts ) scale-like , imbricated, yel¬ 
lowish, ovate or heart-shaped, very different from those of the sterile 
stems and branches. 
Spikes sessile (branches equally leafy to the top). 
5. Lt, ailliotilllllll, L. Much branched; stems prostrate and 
creeping (1°_4° long); the ascending branches similar (o'-8'high), 
sparingly forked, the 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-cylin¬ 
drical, thick. — Yar. pijngehs, Spring, is a reduced subalpine or 
montane form, with shorter and more rigid-pointed erectish leaves.
