Selaginella Parishii sp, nov. 



Plants prostrate, close-creeping, and emitting rootlets through- 

 out, much branched, with mostly short stems ; stems 6—10 cm. 

 long, mostly with short alternate branches or sometimes with 

 more compound ones ; leaves with a dorso-ventral arrangement, 

 brownish below, bright-green above, 5-6-ranked, curved upwards 

 and coiling over the stems when dry, broadly lanceolate, acute, 

 ending in a point but with no terminal bristle, but with 6-20 very 

 short marginal hairs on either side; sporophyls on the ends of 

 short branches, scarcely differing from the leaves, forming short 

 subquadrate strobiles ; microspores orange-yellow, 40— $o/i in 

 diameter, sphero-tetrahedral, long remaining united in tetrads ; 

 macrospores yellow globose, about 350/i in diameter. 



California : Palm Springs, Colorado Desert, March, 1903, 

 C. F. Saunders (comm. S. B. Parish) ; dry rocky mountains in the 

 desert, April, 1882, Parish 1200. 



Mexico : Conception del Oro, Zacatecas, Aug., 1904, Palmer 

 306 (type). 



This species has been known to the writer as distinct for a 

 number of years, and was mentioned in the original breaking up 

 of the group which had passed under the name of S. rupestris (ef. 

 Bull. Torrey Club 25 : 133. 1898), among the species inquirendae. 

 Mr. Parish has more recently sent me specimens with microspores, 

 and from Palmer's recent collections the same plant turns up from 

 Zacatecas with both microspores and macrospores ; all the above- 

 named plants are in the herbarium of the New York Botanical 

 Garden. 



Selaginella Sherwoodi Underw. Torreya 2 : 172. 1902. (Type 

 from Macon County, North Carolina, Sherwood.)
