Indofevillea Jiroi (Cucurbitaceae), a New Floral Oil Producing Species from Northeastern Myanmar

Abstract. A new species of Indofevillea, based on a single male individual discovered in 2001 in Kachin State, northeastern Myanmar, is described. It differs from the only other species in the genus, I. khasiana, in leaf pubescence and shape, calyx and corolla morphology, and structure of the male inflorescence. A phylogenetic analysis based on the nuclear ribosomal ITS region, two plastid genes (rbcL and matK), one intron (trnL), and two spacer regions (trnL-trnF and rpl20-rps12) confirms the close relationship but genetic distinctness of the two species. The presence of oil producing glands on the inner surface of the corolla segments indicates that the new species is pollinated by oil-collecting bees, presumably of the genus Ctenoplectra.
