ABSTRACT

Cryptocoryne is a genus of 64 current species with nine indigenous species recognized from Peninsular Malaysia as well as six interspecific hybrids. Natural hybrids within Cryptocoryne have been reported from Sri Lanka, Thailand, Lao P. D. R., Peninsular Malaysia, Singapore, Sumatera, Sarawak, and Kalimantan. Here we examine hybrid populations from southern Peninsular Malaysia. All hybrids were sterile but propagate vegetatively. Populations vary in morphological appearance of leaves and spathe limbs. Analyzing the different populations found in southern Peninsular Malaysia and comparing these with artificially produced hybrids show that the here-presented populations represent C. ×decus-silvae, hybrids between C. cordata var. cordata and C. nurii var. nurii.
