ria, basin versus paullatim dilatata, leviter torta, rigida, glabra, margine 
subtusque in costa dense remote denticulato-spinosa. Scapus foliis 2—3- 
plo longior, inferne glaber, superne glanduloso-scaber. Perigonium laci- 
niis oblongo -lanceolatis obtusis; filamenta apice bifida, laciniis obtusis, 
antherae eorum incisionem apicalem attingentes. Ovarium oblongo- 
subelavatum, tubereulis 12-seriatim dispositis costatum, inter costas glan- 
dulosum; stylus staminibus brevior, antheras medias attingens.
