| Abstract: | Jatropha tanjorensis Ellis & Saroja, a species found abundantly in Tanjore, Pudukottai, Trichirapalli and Ramnad districts of Tamil Nadu state, India and grown as a fence plant showed intermediacy in phenotypic characters of J. curcas L. and J. gossypifolia L. A detailed survey at its place of occurrence supplemented with data employed from cytological and peroxidase isozyme studies revealed that J. tanjorensis is a natural interspecific hybrid between these two species. Since there was no seed set, propagation through tissue culture using leaf discs was attempted. |
