A total of 28 specimens were examined from BME; CNC, USU, University of California, Riverside, USA; Royal Ontario Museum, Toronto, Canada; Queen Sirikit Botanical Gardens, Thailand), including the holotype.

Discussion.

This species probably occurs throughout much of Southeast Asia. Intensive collecting in other regions will probably produce as many specimens as the TIGER project did in Thailand.
