Hab. Sylvis montosis tropicis Ceyloniz, alt. 4000 ped. ! Walker, &c. 
Caules crassi, carnosi, hic illic radicantes. Folia}—1” lata, petiolo breviora, 
interdum obscure subserrata. Pedicelli solitarii, pollicares. Flores 
aurei, speciosi, l" longi; labello et vexillo pubescente. Ovarium 
hirsutum. 
39. I. LEPTOPODA (Arn. in Hook. Comp. Bot. Mag. ii. 321). Erecta, 
ramosa, glaberrima, caulibus gracilibus, foliis longe petiolatis (1-3") 
lanceolatis ovato-lanceolatisve acuminatis crebre crenato-serratis pe-

vexillo obcordato dorso cornuto, alis horizontaliter patentibus (? I. lati- 
folia, Wall. Cat. 4737, in Herb. Henslow.). An var. I. latifolie, L.? 
Var. B, brevicornu. Calcare abbreviato flore breviore.—I. brevicornu, 
Arn. 1. c. 
Var. y, gibbosa. Sepalo postico cymbiformi subsaccato calcare nullo.— 
Arn. l. c. 
Hab. Sylvis montosis subtropicis Ceyloniz ! alt. 5000-8000 ped., Walker 
&c. (fl. Sept.-Nov.). 
Herba 1-3-pedalis. Caules basi interdum suffruticulosi. Folia sub- 
membranacea, basi attenuata, in var. brevicornu interdum 4-pollicaria. 
Flores 3-3" lati, latiores quam longi, ob petala lateralia horizontaliter 
patentia. Capsula +”, glabra v. puberula. 
Thwaites describes this as being very common and variable, and points 
out its close affinity with I. Leschenaultii, in all my specimens of which 
the leaves are more or less opposite.
