numerosi foliosi adscendentes, plus minus laxe ramoso-racemosi 
rarius uniflori, virescentes, basi vaginis foliorum induratis 
persistentibus seepe dense obsiti. Folia uninervia acuta apicu- 
lata, radicalia et rosularum sterilium lanceolata oblonga vel 
subspathulata in petiolum attenuata, caulina angustiora acutiora ; 
bractes submembranacee glanduloso-pubescentes ; inferiores

plerumque breviter pedicellati. Calyx a basi parum dilatatus 
cylindricus vel elongate obconicus subumbilicatus glanduloso- 
pubescens membranaceus pallide virens vel dilute purpurascens, 
dentibus ovatis obtusissimis margine hyalinis ciliatis. Petala 
supra albida, subtus virescenti-livida, ultra medium bipartita, 
lobis linearibus obtusis, appendicibus brevibus semi-orbicu- 
laribus, unguibus glabris vel superne ciliatis. Filamenta glabra. 
Capsula ovata vel elliptico-oblonga, carpophoro dense retrorsum 
hispido plerumque sesquilongior. Semina fusco-grisea reni- 
formia granulata, faciebus plana, dorso canaliculata. 
A 8. odontopetala differt, colore viridi, indumento minus denso,
