Folia plantse Khasiyyanoe multo magis patentia quam demonsrat 

 Hookeriana icon. — Capsulas seniores tantum vidi, . quarum 

 peristomia decolorata. Praecedenti valde affine, discrepans 

 foliis minus patentibus, membranaceis, lanceolato-acuminatis, 

 marginibusque recurvis.

Omnia fere plant* nepalensis, sed statura major, et ramificatio 

 indistincte pinnata. Variat dentibus peristomii solidis perfora-

4. Pterogonium neckeroides, Griff. 



Caule repente pinnatim ramoso, ramis ascendentibus, foliis as- 

 cendenti-patulis lanceolato-acuminatis planiusculis tenuissime

 annulata, operculo conico-subulato brevi. 



Hab : Super Buddlese speciem arboream Mumbree. 



Rami depressi, siccatione filiformes. Folia sub-4-fariam imbri 

 cata, siccitate adpressa, humore patentia, marginibus medium 

 infra leviter revolutis, areolis angustis, marginalibus baseos 

 majusculis quadratis. 



F. Perichsetialia avenia, acuminibus patulis. 



Seta axillaris, solitaria, vel aggregate, sed ad inflonescentias di- 

 versas semper pertinentes, pallida, sicca tortilis ; vaginula me- 

 diocris, cylindracea ; paraphyses pistillaque paucissima. 



Capsula cylindracea, insequilateralis, utrinque paullo attenuata, 

 brunneo-rufescens. 



Peristomii dentes 16, subulati, simplices, breviusculi, coriacei, 

 solidi, lutescentes, marginibus valde opacis, utrinque margi-
