A very variable and common plant, of whose varieties we have had 
great difficulty 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 $ inch long, including the spur, and not 
" minimi." Some of the varieties appear in the dry state to approach 
very closely some forms of I. longicornu, from which it is very difficult 
to distinguish them. The flowers greatly vary in size, from 4-1 inch 
long, including the spur, and in colour from a deep golden yellow to
