33. Rhynckostegiella Limps. 
41. Rliynckostegiella assamica Card, and Dixon sp. nov. (Plate 
# II, fig. 7 .) 
Caulis reptans, ad terram arete adhoevens, wage ramosus ; folia 
juniora loeteviridia, senilia nigricantia. Folia caulina sat conferta, 
erecto-patentia nec compressa, siccitate vix mutata, circa 1*5 mm. longa,

Hab. Kekar Monnying, Abor District, alt. 800 ft., on silted earth 
on tree trunks, 15th Jan. 1912, leg, Burkill (n. 36014). On stem of 
Ficus pgriformis var. and stones near the stem, alt. 1,200 ft., gorge of 
the Yambung, 9th Jan. 1912 (n. 37766). 
This rather uninteresting little plant is placed by M.jlCardot in 
the Section Lepto-rhynchostegium of Brotherus, but does not seem quite 
at home there, any more than in Eu-rkynchostegiella, The cells are 
somewhat long for the former section, and the leaves scarcely concave. 
The limits between Rhynchostegiella (especially the Section Lepto-rhyn- 
chostegium) and Eurkyuchium seem very ill-defined, and it is doubtful 
whether the separation can be maintained. 
The other Indian species of the genus have the leaves widely spread- 
ing or squarrose with long acute points and a scabrous seta. The
