Selaginellas. 39 



S. Kraussiana. (Syn. dentkulat a hortense.) The best known in gardens, perhaps, 

 of any in the genus, and not the least useful for decorative purposes. S. Africa. 



Var. variegata. Growing branchlets greenish white ; rather pretty. 



S. Martensii. (Syn. Lye. Stolo/aJh-7un.) Stems ascending, 6-l'2 in. long, bearing 

 numerous twice pinnate and forked branches; leaves obliquely ovate, obtuse under- 

 edfe and towards the apex of the upper serrulate ; smaller ones ovate, serrate, with 

 long recurved points. Tiie Canaries. 



Var. Conipacta. (Sjn. Lye. fornwsum.) Stems stouter, nearly erect, 6-9 in. high ; 

 branches crowding and forming a dense head. 



Var. Compaota variegata. Same as last, but with the branches and leaves vari- 

 ously mixed with white. 



S. Galeottii. (Syn. diclwous, Karsteniana, Schottii.) Stems long and trailing, 

 sending out rootlets nearly their whole length, reddish-brown, and beset with distant 

 leaves one-eighth of an inch in length, ovate oblique, denticulate, as are those of the 

 branches ; intermediate ones somewhat pointed ; branches distant, one to several 

 inches long, bearing several mostly forked branchlets. A fine growing species, and 

 likely to become a favorite with florists, as it can be trained several feet high in the 

 form of a pyramid, so as to resemble a miniature evergreen shrub. Mexico. 



S. uncinata. (Syn. Lye. caesium.) Stems long and trailing, branches several 

 times divided ; branchlets short and crowded ; leaves oblong, obtuse, entire ; smaller 

 ones ovate, with slender uncurved points. Chiefly esteemed for the metallic luster 

 of the leaves, which, when grown in a moist warm house in the shade, are very beau- 

 tiful indeed. China. 



S. laevigata. (Syn. caesitwi arhoriuin.) Stems 1-f of an in. in thickness, reddish- 

 brown, as are also the rootlets, 4-6 feet in length ; branches distant, frond-like, 

 ovate-lanceolate, 6-12 in. long; leaves oblong-ovate, entire, not pointed; smaller 

 ones with rather broad obliquely incurved points. A showy species with the iride- 

 scent hue of uncenata., and when trained to a stake or twisted around several in the 

 form of a cylinder, is very striking and attractive. Madagascar. 



S- serpens. (Syn. mutabilis, Jamaice7isis, variabilis.) Stems prostrate, rooting 

 their whole length ; branches pinnate ; spikes 1-f of an in. in length, bearing nu- 

 merous large spore cases in the axles of wedge-shaped, serrate, leaves ; leaves of the 

 branches ovate, blunt, sparingly serrate, their edges turned upwards ; smaller ones 

 apressed, pointed. The whole plant light green in color, appearing almost white in 

 the twilight. West Indies. 



S. Poulterii. Stems slender and spreading, 3-4 in. high ; branches distant, forked ; 

 large spore eases conspicuous ; leaves one-sixteenth of an inch in length, round ovate, 

 straight, obliquely pointed or blunt, ciliate ; smaller ones ovate with straight points, 

 ciliate-dentate. A diminutive species, but quite interesting in a collection. 



S. inequalifolia. Stems reddish-brown, ascending, 6-9 in. high ; branches alter- 

 nate, distant, fan-shaped, or palmately forked ; leaves on stem distant, obliquely 

 ovate, pointed, entire; those of the branches imbricated, half as large with short 

 points. Very handsome. Java. 



S. Griffithii. Stems 6-10 in. high, nearly erect with nodding tips, reddish-brown 

 as are also the long rootlets borne on half their length ; branches alternate, bi-pin-
