ovales, convexe, pellucida, trigonis angularibus aucte. Foliola 
duplo breviora, appressa, oblonga vel subobovata, ad 3 bifida, sinu 
lato lunato, segmentis tenuicuspidatis, utrinque supra basin 
hastatim unispinis, ipsa basi cum foliis brevissime connata. 
Flores 2 terminales; bractee laxm, foliis vix diverse, paullo 
breviores et latiores; bracteola foliolis conformis. Perianthia 
alte emersa, exacte oviformia, pallida, fragilia, inflata, solum

Hab. Dominica, in monte Trois Pitons dicto, ad arbores 
(Eviiort, no. 772, Nov. 1892).—Affinis DL. Chamissonis (L. et 
G.), distincta tamen forma foliorum, cellulis magnis, periauthio 
turgido, ore constricto, ete. 
Genus 17. Puactocuiia, Dum. 
Plagiochila, as was to be expected, is in great force. I 
enumerate 21 species collected by Mr. Elliott, rather more 
species having occurred in St. Vincent than in Dominica, which 
is contrary to the proportion in most other genera. Of the 
whole number only one appears to be quite new, and I have 
ventured to dedicate it to Mr. Elliott. The rest all occur in 
other West Indian islands. A very few spread along the 
Andes to the Equator, but, so far as I know, only a single 
species reaches the southern tropic.
