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.
