Erythrina calcicola sp. nov. (Fabaceae) from Thailand

Abstract

In the context of an ongoing survey of limestone ecosystem in Phu Khieo-Nam Nao Forest Complex in Thailand, we describe and illustrate a new species under the name Erythrina calcicola Tetsana & Poopath. Morphologically, it is particularly similar to E. stricta Roxb. which distributed in the mainland Southeast Asia, but it differs in the shape and size of leaflets, size of flowers and fruits, and shape of calyx and standard blade. Currently, E. calcicola is only known from Tham Pha Sawan temple, Loei province, northeastern Thailand.
