PORELLA. 329 
interiores foliis caulinis haud minores, iisdem latiores, ineequaliter 
ciliolate; bracteola biloba, 
Perianthia emersa ovato-oblonga compressula obtuse tricarinata, ore 
truncato ciliolata. 
Andrecia brevispica, pinnam totam vel ejus apicem solum sistentia ; 
bracteze foliis breviores latioresque ventricosee; bracteole magne 
subquadratze, apice rotundato-truncato 4-crenate. Stirps Grana- 
tensis subminor est, arctius pinnata, foliorum lobo basi interna 
spinis seepissime binis deorsum spectantibus armato, quasi bicaudato 
(neque, ac in planta Peruviana, simpliciter caudato), 
Obs. Distinguished from the other crisped-leaved species by the leaves 
being nearly entire, and by the very broad underleaves, which are not 
decurrent and laciniate at the basal angles. Hooker’s figure and 
description accord so well with my plant that I refer it confidently to 
his Jung. crispata. It is true that the figure shows the underleaves 
obcordate, and so they are, but in appearance only, from the reflexion of 
the obtuse apex. Humboldt gathered the original specimens in the 
Andes, a few degrees north of the equator ; I mine a few degrees south ; 
in both cases, no flowers were observed. Mr Webster, however, has picked 
specimens off Orchid bulbs, sent to Messrs Backhouse from the highlands 
of New Granada, and on them I find flowers of both sexes and perianths.
