white, or even pale purple, and they are often speckled with rose-colour 
or purple spots. Edgeworth describes a variety of his I. micranthemum 
as having the spur reduced to a small sac, from which, as well as from 
the size of the flowers of some of his specimens, I am inclined to suspect 
that his plant, or some of it, may be referable to I. brachycentra, K. & 
K. The I. candida, Lindl., doubtfully referred here by Edgeworth, is 
certainly a very different plant, having very large flowers, and being 
undoubtedly a variety of I. Roylei. Edgeworth's I. elata appears from 
his specimens to be a form of I. /eptoceras, but the specimens are not 
sufficient for satisfactory determination. 
This species is on the whole most nearly allied to I. tingens, but di- 
stinguished by its much larger flowers and longer spur; some specimens 
are, however, with difficulty distinguishable. There are sometimes pedi- 
cellate glands on the basal margins of the leaves.

Very similar indeed to I. leptoceras, and probably only a form of that 
plant; but distinguished by its shorter spur and usually lilac lateral 
petals. Most of my specimens have rounded lobes to the petals, but in 
one of Strachey and Winterbottom's the lower lobe terminates in a long 
subulate tail. 
93. I. Lemanni (Н. f. 5 T.). Erecta, glabra, caule ramoso, ramis 
suboppositis, foliis longe petiolatis late ovatis obtusis obtuse dentatis, 
pedunculis elongatis apice flores 3-5 gerentibus, bracteis parvis late 
ovatis, floribus majusculis, sepalis late ovato-cordatis, vexillo hemi- 
spherico, labello late infundibuliformi in calear elongatum gracile in-
