seminibus (fid. Wt.) reticulatis. 



According to Wight, this difi\3rs from I. Leschenaultii in the form of 

 the flower, long straight spur, and reticulated seed, but all my specimens 

 have incurved spurs (as in /. Leschenaultii), the seeds in all seem to have 

 a spongy testa which is rugose when dry, and the difl^erence in the form 

 of the detals is not so strong in my specimens as in Wight's figure. /.
