ABSTRACT
Camchaya khongchiamensis Chatan & Promprom (Asteraceae), a new species from Ubon Ratchathani Province, Thailand, is described and illustrated. It is similar to C. loloana, but clearly different from C. loloana by having a larger size of capitula, involucre, receptacle, and corolla lobe. In addition, it mostly has fewer florets (18–40 [−50]) per capitulum; lower haft whitish, upper haft purplish corolla tubes; sagittate base anthers; and white except for the purple near apex style. A distribution map, pollen morphology, and a table with comparative morphological characters of the new species and its closest relative are provided, as well as the preliminary conservation assessment under the IUCN criteria.
