    interiores foliis caulinis baud minores, iisdem latiores, inaequaliter ciliolatae; bracteola biloba, Perianthia emersa ovato-oblonga compressula obtuse tricarinata, ore truncato ciliolata. Androecia brevispica, pinnam totam vel ejus apicem solum sistentia ; bracteae foliis breviores latioresque ventricosae; bracteolae magnte subquadratae, apice rotundato-truncato 4-crenatae. Stirps Grana- tensis subminor est, arctius pinnata, foliorum lobo basi interna spinis ssepissime 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 ; 1 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. 2.
