 brevissima acuta denticuliformia. Pericarpium exsuccum, indehiscens, villosum, basi styli aristatum, perianthio scarioso et filamentis emarcidis cinctum, abortione mouospermum. Semen turgidum obovatum retusum, integumento (testâ) simplici membranaceo aqueo-pallido, hinc (intus) fere a basi acutiuscula, raphe fusca verticem retusum attingente ibique in chalazam parvam concolorem ampliata. Albumen semini conforme densè carnosum album.
