Discussion and Conclusion
A morphological analysis provides evidences that the Indigofera jodhpurense reported here is a new species. It shares a close relationship with I. cordifolia , that has been found in several Indian states including Rajasthan and I. jaisalmerica , which grows only in the Jaisalmer area of Rajasthan. Since both of these species I. cordifolia and I. jaisalmerica are found in environments with comparable climatic conditions in the state of Rajasthan, a detailed analysis of the new species from the Jodhpur district indicated that it appears to be more prevalent. In terms of one-seeded legumes, these species are closely related to one another.Indigofera jodhpurense often produces one-seeded legumes, butI. jaisalmerica produces purely one-seeded pods and I. jodhpurense occasionally produces two-seeded legumes. Additionally, there is a wide range in the number of blooms per inflorescence. Both of these species of Indigofera (I. jodhpurense and I. jaisalmerica ) branches have similar, ascending arching, which sets them apart from I. cordifolia which is plageotropical, almost horizontal branching structure ( Fig. 1 Table 1) contains the additional information. The vascular bundle layouts of the new species and I. cordifolia seem to be very different from one another (Fig.4). Biramous hair is indeed a hair pattern that is prevalent in basically allIndigofera species (Gillet 1958). Indigofera has also been found to have various kinds of hairs. Other species with uniseriate or biseriate have also been found in other old world species (Lieven, 1992) and I. jodhpurense has shown comparable results.
