Nothapodytes burmanica (Icacinaceae), a new species from Kachin State, Myanmar

Abstract

Nothapodytes burmanica Y.H.Tan & S.K.Shen, sp. nov. (Icacinaceae) from Kachin State, Myanmar is described and illustrated. It belongs to Nothapodytes due to the lorate hairy petals being connate at the base and a fleshy foliaceous disk divided into five leaflike lobes. Morphological and phylogenetic evidence indicates that it is close to N. pittosporoides. Morphologically, both species have oblanceolate or oblong leaf blades that are adaxially sparsely pubescent, but the new species is distinguished by its leaf base usually being oblique, and the paniculate inflorescence that has more numerous but smaller flowers with shorter petals. Phylogenetic results indicate that N. burmanica is deeply nested within the genus and forms a sister group of N. pittosporoides.
