E'uhumata. ~ B.. perpusillae v. A. v. R. valde affinis, sed: 

 Frondes stériles similes ; frondes fertiles segmentis valde con- 

 tractis, segmentis soriferis elongatis stipitatisque ; sori ad basin 

 dentium valde elongatorum falcatorumque (corniculatorum) inserti. 



H. pusilla J. Syn. differs from this in having the fronds 

 larger, more resembling a small form of H. alpina Moore; H. 

 perpusilla bas the soriferous segments short, adnate, and the 

 teeth or horns projecting beyond the sori much shorter.
