MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



Neolepidozia Fulford & J. Taylor, Brittonia 11: 81-82. /. 28-41. 1959. 



Lepidozia auctt. p.p. 



Telaranea subg. Neolepidozia Schuster, Jour. Hattori Bot. Lab. 26: 254. 1963. 



Plants small, light green to olive-green or reddish; stems pinnate to bipinnate, 

 the lateral branches leafy, of the Frullania type, subtended by a bifid dorsal 

 half-leaf, often becoming flagelliform in the outer part, the ventral branches 

 intercalary, in the axils of the underleaves, long flagelliform or short sexual; 

 stem in transverse section elliptical, with a unistratose cortical layer of mostly 

 twelve large thin-walled cells surrounding a medulla of numerous thin-walled 

 cells. Rhizoids colorless, from cells of the underleaves, the scales of flagelliform 

 branches, and the base of the female branch. Line of leaf insertion oblique, almost 

 longitudinal, the leaves incubous. Leaves symmetric to asymmetric, sub- 

 quadrate, subrectangular or cuneate in outline, divided above into four triangular 

 segments, only three on the branch leaves, the margins entire. Underleaves 

 transversely inserted, similar to the leaves but smaller. Plants dioicous, the short 

 sexual branches ventral intercalary, or the male inflorescence intercalary on a 

 stem or branch ; male bracts and bracteoles in to ten series, the bracts monandrous, 

 concave, bifid above, the bracteoles smaller, plane; antheridia subglobose. 

 Female branches very short, the bracts and bracteoles similar, different from 

 the leaves and underleaves, in three or four series, broadly ovate, divided above 

 into three or four short segments, the margins with occasional short teeth. 

 Perianth 3^ mm long, 4 or 5 layers of cells below, one-layered above, cylindrical 

 and with three broad keels below, contracted above, the mouth crenulate. Capsule 

 wall of three layers of cells, the seta with 8 large outer cells surrounding 16 inner 

 cells. 



Type species: Jungermannia capilligera Schwaegrichen. 



This small genus with an Antarctic distribution is best characterized by its 

 green color and small size, the oblique, nearly longitudinal line of leaf insertion, 

 a cortex of one layer of twelve longitudinal rows of large thin-walled cells 

 surrounding the medulla, and the small, triangular segments of the leaves and 

 underleaves. 



Key To The Species 



. Leaves cuneate, quadrifid to one-half of their length; segments widely divergent; 



leaf-cells in many rows except for the 8-rowed base. 1. N. capilligera. 



, Leaves rectangular, quadrifid to one-fourth or one-third of their length; segments 



straight or only slightly spreading. 

 2. Segments of the leaves two or three cells wide at the base, mostly five or six cells 



long; leaf-cells in more than eight longitudinal rows. 2. N. serintitexta. 



2. Segments of the leaves two cells wide at the base, three cells long; leaf-cells in eight 



longitudinal rows. 3. X. oligophylla.

Plants small, olive-brown, in tufts or mats or among other bryophytes; stems 

 to 2 cm long, regularly pinnate, the lateral branches becoming flagelliform at 

 the tips, the ventral branches long flagelliform; in transverse section the stem
