Chiang Mai, endemic, Gomphostemmateae, Mae Rim district, new species


Chelonopsis thailandica A.J.Paton, Suddee & Bongch. is described and illustrated here. The new species belongs in Chelonopsis Sect. Aequidens being a small shrub with an equally lobed calyx, lanceolate leaves and eglandular hairs. The new species differs from the other species in the section in having a remotely toothed leaf margin and denser indumentum. This is the first species of Chelonopsis to be recorded from Thailand. Only one specimen has been seen and it is possible that the habitat where the collection was made in Chiang Mai Province no longer exists.
