This is one of the largest species which I am yet acquainted 
with of the genus Hookeria, and cannot be mistaken for any 
other. The leaves are similar to those of H. pallescens (vide 
Tas, XXXVIII.); but the rest of the plant is totally different, 
the calyptra especially, which is beset with the paraphyses (of 
Hedwig) as well as the pistilliform bodies, both of which are 
very numerous about the perichetium.,
