648 LYCOPODIACEAE. [Selaginella. 
1. S. deflexa, Brack. Fil. U. S. E. E. p. 332, tab. 45. — Stems slender, 
dividing near the base into several erect branches, 4—7‘ high, leafy 
throughout. Leaves all of one kind in opposite decussate pairs, forming 
4 ranks; the sterile ones green, patent or reflected, ovate-lanceolate, 
1—1!/2“, long- and sharply acuminate, serrate in the betadar portion; the 
upper fertile ones paler, straw-colored, patent-erect, larger, 1!/2—21/2"', 
broad deltoid or orbicular, suddenly narrowing to a long point, spinoso- 
serrate. Macrosporangia numerous and large, opening with 3 or 4 valves, 
their globules white, papillate. Minton broadly transverse, sub- 
reniform, 2-valved; their spores muricate

mostly hold microsporangia with only a few macrosporangia at the e. In the other 
form the fertile leaves, chiefly with macrosporangia, occupy loosely ba upper half and 
more of the upright stem and branches. 
. S. parvula, sp. — Stems filiform, trigonous, the posterior face 
with a median line; bie sterile branches regularly dichotomous and en- 
tangled, forming a densely matted moss-like tuft; the fertile branches or 
stems erect, 1—2‘ high, dividing from near the base, but excurrent to 
the apex. Caulin sind branch-leaves alike in shape, but the former 
smaller; the 1 rene leaves all horizontally patent and distant, most so in 
‘the sterile branches, broadly and obliquely obovate or oblong, 1/s—%2", 
obtuse, quite entire on both margins, with a rounded base, conchoid. 
Intermediate leaves 1/3—-1/4 as large, scarcely projecting beyond the rhachis, 
almost in one row, ovate or obovate, obliquely mucronate, rounded at the 
tire, or faintly denticulate on the outer margin. Spikes 2—4” 
Sane scarcely narrower than the branches, the bracts rather patent, ovate, 
a , keeled, entire or amg bcc late. Macrosporangia numerous, 
with 3 or 4 white and smooth ules in each; the microsporangia few, 
confined to the apex of the rsikeloe: spores ee smooth.

3. S. arbuscula, Spring, ast Lycop. If, 183. — Stems erect from 
a rooting base, 3—8’ high, copiously branching from the middle upward 
in a dense pyramidal frond ae a dark and dull green, often broad above 
by shortening of the axis, the branches erect, with stiff appressed branch- 
lets. Stem-leaves close, more or less dimorphous, the posterior ones 
ovate, conchoid, about 1! long. Lateral branch-leaves erecto-patent,
