Cyrtosperma sp

by Wilbert Hetterscheid

With 12 species, Cyrtosperma is a small genus. All species with the exception of C. merkusii are confined to New Guinea and associated islands. The wide spread of C. merkusii in Malesia is certainly due to it being transported by man because it was a major food crop once, though in that capacity it is now in decline.

Cyrtosperma species are slender to gigantic geophytes with a creeping rhizome and heavily armoured with prickly leaf stalks. The flowers are fully bisexual. They are often found in swampy conditions.
