Two new species of Callerya Endl. (Leguminosae: Papilionoideae) from Thailand

Callerya chlorantha and C. tenasserimensis, here illustrated and described as new to science, are found in dry deciduous or bamboo forest in Kanchanaburi and Ratchaburi provinces in Thailand. Callerya chlorantha, characterized by having pale green flowers that are rare in the genus, grows on limestone. This species is considered as Data Deficient (DD) at this time because there are not yet sufficient data about its distribution, abundance or threats. Callerya tenasserimensis has glabrous leaves and stems and rather small, purple or maroon flowers with golden-brown hairs on the calyx and abaxial side of the standard petal. The conservation status of this species is assessed as Vulnerable (VU).
