A very variable and common plant, of whose varieties we have had 

 great difiiculty in disposing, being at first inclined to divide our exten- 

 sive series of specimens into six very local species; but when these 

 became the subjects of comparative study along with our own and 

 Cathcart's drawings, and with the suites of specimens from Wallich, 

 Lobb, Strachey and Winterbottom, and especially of Edgeworth, it 

 became at once apparent that to our six we must add as many other 

 local species, not so much because they were distinct, as because they 

 were intermediate in habit and characters (though not in geographical 

 distribution) from our own. Under these circumstances we have thought 

 it best to unite them all. 



With regard to the name, we have adopted that applied by Wallich 

 to good specimens in his own Herbarium, though under the same number 

 we find also I. racemosa, I. tingens, and others. The I. micranthemum, 

 Edgew., according to Edgeworth's specimens in Herb. Benth., is hardly 

 different from I. laxiflorum, and differs from his description in Linn, 

 Trans, in the flowers being fully f inch long, including the spur, and not 

 " minimi.'* Some of the varieties appear in the dry state to approach 

 very closely some forms of /. longicornu, from which it is very difficult 

 to distinguish them. The flowers greatly vary in size, from i-1 inch 

 long, including the spur, and in colour from a deep golden yellow to
