It resembles Asperula karataviensis Pavl. in floral structure but the leaves are larger and the inflorescence is not dichotomously branched. In general habit it has much resemblance with Calium asperifolium Wall. but flowers are distinctly tubular and bracteolate. More material is needed in order to reach a definite decision.
