Notes on the Identity and Typification of Euphorbia hypericifolia L. (Euphorbiaceae) with Special Reference to India

The true Euphorbia hypericifolia L., was long beleived to be represented only in the New World. According to Boissier, E. hypericifolia L., does not belong to Asia. After critical studies made on a large number of herbarium speciemens and field observations it became clear that E. hypericifolia is an introduction and was in India only for the last 4-5 decades. The major distinguishing features of this species is its erect habit, glabrous nature, axillary or terminal clustered cyathia, stalked rounded glands, subspherical glabrous capsules and finely ovoid convex-faced wrinkled seeds.
