According to Wight, this differs from I. Leschenaultii in the form of 
the flower, long straight spur, and reticulated seed, but all my specimens 
have incurved spurs (as in I. Leschenaultii), the seeds in all seem to have 
a spongy testa which is rugose when dry, and the difference in the form 
of the detals is not so strong in my specimens as in Wight’s figure. I.
