Hab. A scrap picked off a Lichen from Pichincha. Prof. 



W. Jameson. 



Shoots straggling, dark green, 1-2 inches high. Leaves 

 on their upper part with divaricating spines as in Gymnanthe 

 Wilsoni, Tayl., but on the inferior margin simply dentate. 

 It is allied to P. decipiens, Lind., by its size, colour and habit, 

 but differs essentially by the recurved dorsal margin of the 

 leaves, these, besides are secund, and have the ventral mar- 

 gin dentate. 



18. V.pallentifolia, Hook. fil. et Tayl. j caule caespitoso, ad- 

 scendente, subramoso ; foliis imbricatis, erecto-patentibus, 

 concavis, oblongo-ovatis, emarginato-bidentatis, ceeterum 

 integerrimis, margine dorsali recurvo.

Stems very slender, about £ inch long, pale olive. Shoots 

 compressed. Leaves in a series, rapidly increasing towards 

 the summit of the shoot, the upper pair, sometimes, without 

 any emargination. This is allied to P. dendroides, Nees, 

 from Java, but the leaves are wider and shorter, the sinus 

 more shallow and the cellules far more minute. 



19. P. connexa, Hook. fil. et Tayl.; caule implexo, adscen- 

 dente, incurvo, subramoso, apice incrassato, demum pro- 

 lifero ; foliis imbricatis, oppositis, verticalibus, adpressis, 

 late orbiculatis, connatis, inferioribus integerrimis, supe- 

 rioribus subdenticulatis.
