Abstract
Crawfurdia minuticalyx, a new species of Crawfurdia (Gentianaceae) is described here from Arunachal Pradesh, situated in Eastern part of Indian Himalayan Region (IHR). This new species is unique in its very small calyx from its allied taxa. Morphologically, it shows close affinity towards C. speciosa Wall.; however, it can be differentiated by its much smaller leaves with entire margin; minute, non-splitted, calyx; relatively shorter corolla; stamens inserted below the middle of the corolla-tube, oblong anthers; short gynophore, and very short style. A detailed description and illustration are provided here along with comparative table of morphological characters, for easy identification.
