Read the Free to Read paper in Nordic Journal of Botany, by De Jong et al. (2025): Euphorbia paraikalli sp. nov., a new succulent species of Euphorbiaceae from Peninsular India.
Abstract:
Euphorbia paraikalli, a new succulent species allied to Euphorbia susan-holmesiae Binojk. & Gopalan is described in the present communication. The species differs from Euphorbia susan-holmesiae in its habit, wider and shorter segments, densely packed whorls of branches, up to 6 wings, larger leaves, trapezoidal glands, capsules with rounded lobes, and brown speckled seeds. Euphorbia susan-holmesiae is only known from a single locality in Tirunelveli District, whereas E. paraikalli is found in sporadic populations in the hills that mark the southern boundary of the Deccan Plateau.
