caule et ramulis terminales, erecti, stricti, ampli, ¿-1-pedales, multiflori, juveniles bracteis apice 
densius congestis breviter comosi. Flores ex majoribus et speciosissimis totius generis, in pedun- 
culo communi pilis brevibus patulis vestito densiuscule gregati, una eum bracteis, bracteolis pedicel-

scariose, 3-4 lin. longe, ovato-lanceolatæ, longe acuminatæ, patulæ, una cum bracteolis itidem patulis 
paullo brevioribus obtusioribusque persistentes. Pedicelli graciles, 4-3 poll. longi, albido-pilosi, sub 
anthesi horizontaliter patentes, demum arcuato-deflexi, fructiferi cernui. Sepala 5, omnia libera; 
tria exteriora inter se subæqualia, parva, 11-2 lin. longa, obovato-elliptica, obtusiuscula, extus sparse 
pilosa; interiora (ale) multo majora, etinnisile roseo-purpurea, oblique lato-obovata vel fere orbicu-

ad faciem internam laminz partis cum vagina staminali connatæ piloso-pubescentia, ad ejusdem 
partem liberam glabra, verticaliter sursum curvata, apice obtusa vel subtruncata. Staminum vagina basi 
juxta margines piloso-ciliolata; antheræ oblongo-ovoideæ, obiter compressæ, subtiliter puberulæ vel 
sepius omnino glabræ, apice oblique truncato biporosæ (septulo parum efformato vel deliquescente ?) 
uniloculares. Pollinis granula (in una eademque anthera) nunc spheeroidea nunc breviter-ellipsoidea, 
longitudinaliter costato-striata, sensu directioni costularum contrario et non raro jam intra antheras 
needum apertas tubificantia. Ovarium obovatum, vertice circa styli insertionem pilosum ; stylus 
compressus latiusculus, medio dilatatus, paullo supra medium arcuatus, ad apicem plus minusve oblique 
truncatus vel obscure angulatus, anguste stigmatosus. Capsula obcordata, rigidulo-membranacea, 
22-3 lineis vix longior, compressa, anguste marginata, ad apicem nunc pilis raris obsita nunc omnino 
glabra, disco utrinque bigibba. Semina oblongo-obovoidea, circiter 14 lin. longa, pilosa, vertice
