12. SELAGINELLACE^. [1. Selaginella. 



B. Sporophylls of two kinds like tlie leaves. Small fugacious 

 species : — 

 Stem decumbent and rooting at intervals . . .10. proniflora. 



Stem erect or ascending, rooting only at base . . 11. tenera. 



1. S. rupestris. Spring. 



A small Lycopodium-\ike plant with densely caespitose decumbent 

 and ascending mostly monopodially branched stems only a few inches 

 high or attaining 6-12" in length, Avith distant usually pinnately 

 arranged branches. Leaves all round the stem, similar to one another, 

 close, erect or ascending, linear or subulate, • 1- ■ 2" long without the 

 long hair-tip, margins minutely ciliolate. Spikes or flowers scarcely 

 differentiated, sessile, -5-1" long by 04" diam., sporophylls rigid, 

 ovate-lanceolate, acute, much imbricated, acutely keeled. 



On rocks, higher mountains of Chota Nagpur above 3000 ft. Parasnath ! Fr. 

 Xov. 



In our plant the base of the leaves is bearded. ■ The plant becomes closely 

 curled up in the cold season. 



2. S. exigua, Spring. 



A very snail plant with densely tufted slender stems lo-2" long, 

 decumbent with roots from the lower half only ; branches closely 

 pinnate, lower compound. Leaves in two planes, crowded on the 

 branches, laxer on the main stems, membranous, pale green, •OG--!" 

 long, those of the upper plane somewhat smaller, obliquely ovate, 

 acute, subcordate and shortly ciliate on the acroscopic edge at 

 the base, those of upper jolane cuspidate. Sporophylls altogether 

 like the leaves, or slightly larger {not smaller as in most Selaginella), 

 and those of the upper and lower plane scarcely different, ovate, 

 acute keeled, the flower axis about -OS--!" long only. Sporocarps 

 pale yellow, 02" diam. 



Eanchi, Hundrughagh, Prain (the specimen called proniflora) ! It is probably 

 much more common on damp rocks than would appear from the single collection. 

 The Hundrughagh waterfall, however, is a very special locality. Somewhat like 

 ■proniflora before the latter flowers (although the dorsal leaves are much smaller 

 than the ventral in proniflora). Unless looked at closely the flowers of exigua 

 are not at all evident ; in proniflora they are very evident. 



3. S. flaccida, S])ring. 



Stems suberect 6"-l ft. long with roots only near the base and 

 copious pinnately arranged short erecto-patent copiously compound 

 branches down to the base. Distinctly dorsiventral. Leaves mem- 

 branous (but not nearly so thin as in exigua and jy^'oni flora), ventral 

 larger, often contiguous on the branches, ovate-oblong, acute, base 

 subequal, neither ciliate nor imbricated over the stem, -08" long, 

 dorsal leaves more than half as long, rather oblique, strongly cuspi- 

 date. Flowers copious slender o-l" long, with lanceolate cuspidate 

 erecto-patent sporophylls -06" long. 



Koderma, Hazaribagh on wet banks ! Fl. Nov .-Dec. 



4. S. semicordata, Spring. Syn. Lycopodium semicordatum, Wall. 



(No. 126 part). 

 A slender procumbent plant often 1 ft. long copiously piimately 

 branched ; stem pale bisulcate above, main branches short rather
