Iris junzifengensis, A New Species of Iridaceae from Fujian

Abstract:

Iris junzifengensis S. P. Chen, X. Y. Chen & L. Ma, a new species of Iridaceae from Mingxi County, Fujian Province of East China, is described and illustrated here. The new species is similar to I. japonica Thunb. and I. formosana Ohwi, but is distinguished from the former by the broad leaf blades with distinct veins and rough surface, terminal sparse racemose cyme with 2-6 branches, bigger flowers that are 5.0-7.0 cm in diam, perianth with undulate margin and retuse apex, and triangular cylindrical capsule, and from the latter by smaller flowers, perianth with undulate margin and retuse apex, and triangular cylindrical capsule. The comparison of morphological characteristics and molecular phylogenetic analysis both support the establishment of the new species.
