180. §. nupovicana A, Br. in Ann. Be. Nat., 4 ser., xiii. 58; 
S. apus var. denticulata Spring Mon 77. — Stems pars 
b 
am.; bracts ovate-lanceolate, a line long, strongly keeled. 
Hab ama and Louisiana, Drummond 485. A near ally of 
n. 
ebm.; S. sarmentosa Liebm., non A. Br.; 
S. Moritziana Fourn. Crypt. Mex. 148, vix Spring.—Stems trailing, 
2-4 in. long, copiously pinnate, the short erecto-patent branches 
mostly simple. Upper leaves of the lower plane close, erecto- 
patent ; lower spaced, spreading, ovate, acute, at most a line long, 
firm in texture for this group, more produced on the upper side of 
the midrib, spuriously 2-nerved, very cordate, shortly ciliated, and 
much imbricated over the stem on the upper side at the base; 
leaves of the upper plane half as long, oblique ovate, with a long 
cusp. Spikes short, under 1 lin. diam.; bracts ovate-lanceolate, 
strongly keeled. 
Hab. Mexico, Liebmann! A near ally of S. Moritziana, with 
which Fournier unites it. 
132. S. muscosa Spring. Mon. ii. 100.— Stems slender, flaccid, 
twisted, trailing, tufted, 8—4 in. long, copiously pinnate, the lower 
branches sparingly compound. Leaves of the lower plane spaced, 
ovate, subobtuse, a line long, unequally spreading, sometimes 
inflexed or reflexed, subcordate on both sides at the base, moré 
produced on the upper, minutely ciliated, and imbricated over the 
stem; leaves of the upper plane scarcely smaller, curved, con-

133. 8. apus Spring Mon. ii. 75, ex parte; S. albidula Spring 
Mon. ii. 95; Lycopodium apodum Linn.!; L. albidulum Sw.—Stems 
slender, trailing, densely matted, 1-4 in. long, angled on the face, 
the short distant erecto-patent branches simple or forked. Leaves 
of the lower plane spaced below the tip of the branches, the uppet 
spreading, the lower reflexed, ovate, acute, 4 lin. long, pale green, 
membranous, unequal-sided, more produce e upper side of 
the midrib, serrulate, not distinctly ciliated, cordate on the uppet 
side at the base, and a little imbricated over the stem; leaves of 
the upper plane half as long, ovate, shortly cuspidate. Spikes 4-4 
in. long, 1-12th to 1-8th in. diam.; bracts ovate, acute, mem- 
cae about a line long, strongly serrulate, acutely keeled in the 
upper half. 
Hab. Canada, and through the United States to Texas. Com- 
mon in cultivation. Interesting geographically as a representative . 
in the temperate zone of a characteristically tropical group.
