3. Selaginella deflexa, Sp. Nov. (Tab. 45.) 



S, caulibus assurgentibus basi rarnosis; rarnis gracilibus suberectis; 

 foliis quadriseriatis deflexis oblongis acuminatis carinatis spinuloso- 

 serratis; spicis teretibus sessilibus. 



Hab. Kauai and Oahu, Sandwich Islands : in the mountains, on 

 trees; rare. 



Plant 4 to 6 inches high, growing in tufts composed of a very few 

 stems, which are assurgent, and dividing about an inch above the root 

 into an indefinite number of branches. Branches nearly erect, slender, 

 terminated by a yellow, round, sessile, fertile spike, of an inch or two 

 in length. Leaves usually in 4 rows, defiexed, oblong-acuminate, heeled 

 behind, the lower ones nearly entire, those on the upper part of the 

 plant spinulose-serrate and more spreading. Antheridia somewhat 

 reniform, filled with a yellowish powder. Oophoridia globose, con- 

 taining 3 or 4 nearly round, echinate, yellowish grains. 



This differs from S. uliginosa in its more dense, narrower and 

 longer, defiexed, spinulose-serrate leaves.
