A NEW SPECIES OF HETEROPOLYGONATUM (ASPARAGACEAE: CONVALLARIOIDEAE, POLYGONATEAE) FROM THE GAOLIGONGSHAN IN EASTERN MYANMAR AND WESTERN CHINA

Abstract

A new species of Heteropolygonatum, H. farreri, is described from the easternmost part of Myanmar and western Yunnan in a limestone region of the Gaoligongshan. It is morphologically similar to Heteropolygonatum marmoratum but differs by its shortly scabrous stem, narrowly cylindrical perianth with lanceolate tepals, red-orange fruit, and diploid chromosome count. An illustration of the new species is provided, as is a map of its distribution and that of its closest relative, Heteropolygonatum marmoratum, showing their disjunction. Chromosome counts for Heteropolygonatum farreri (2n = 32) and a second count for H. marmoratum (2n = 4x = 64) are given.
