Family Xll.—SELA CINELLACE.E. 



Sporangia of two kinds, the smaller containing numerous 

 micro-spores, the latter containing one to six macro-spores; 

 prothallia very much reduced, especially the male; the female 

 does not leave the spore. — Slender herbs, branching apparently 

 dichotomous; lateral shoots well developed. Leaves small, 

 thin, scale-like, ligulate, crowded round the stems and branches 

 in four row^s, the rows often unequal. Sporophylls usually 

 collected into spike-like cones, the sporangia sessile in their 

 axils, the macrosporangia being at the base of the cone. 



Only genus i. Selaginella. 



I. Selaginella, Spring. 



Stems much-branched, often creeping, bearing roots on the 

 lower sides and leaves on the upper, with terminal cones of 

 sporangia. — Most of the species live in damp places, especially 

 in forests, but there are a few xerophytes found in dry, rocky 

 places. 



Leaves all of one kind, set all round the stem. 



Perennial, procumbent, leaves awned i. rupestris.. 



Leaves of two kinds, one line of larger spreading 

 leaves along both sides of the decumbent stem, two 

 lines of smaller, ascending leaves on the upper sur- 

 face. 

 Perennial plants of firm texture : 



Stem jointed, 6 to 12 in. long, much branched. 



2. Kranssiana.. 

 Annual plants of thin texture : 



Leaves strongly ciliated on the upper side at the 

 base; smaller leaves cuspidate; spike J line in 



diameter 4. tectissima. 



Leaves not .at all ciliated 3. integcrrima.
