FLORAL AND FRUIT MORPHOLOGY OF NEPENTHES LOWII AND N. VILLOSA,MONTANE CARNIVORES OF BORNEO

Floral structure and function and some aspects of development are illustrated for Nepenthes lowii and N. villosa. The floral nectar glands are similar in structure to nectar glands and digestive glands of pitchers. The stamens are fused and form an anther-head, but identities of individual stamens are mostly retained. Placentation is laminar. Evidence of entomophily is presented. Only 4.5% of the seeds in the sample bore embryos, and fertile seeds lack endosperm. There is need of field observations on pollination.
