 Lepchas.

This species is most closely allied to A. glabra, but at once distinguished bv the softly 



tawny-yillose fronds, and the sori more nearly parallel with the midrib than in that 



pec.es. _ It has also a much less proliferous habit than A. glabra : indeed it is rare to 



_ specimens with even three ramifications from the main caudex ; and these always 



origmate from adventMous buds, nerer, that I have seen, by bifurcation of the axis. 



t IS the 'paluh-nok' of the Lepchas, or the black "paluh, as distinguished by its 



dark ebony-coloured stipe from the light mahogany-brown of those of their " paluh "
