tuberculata in the longer spur and even capsules, from small states of 
I. Roylei in the small size, narrower capsules, subulate bracts and conical 
spur ; from I. longicornu and its allies by the capsules being shorter, and 
forming an angle with the pedicel. 
29. I. suLCATA (Wall. Cat. 4764). Caulibus erectis crassis sulcatis, 
foliis inflorescentia et floribus fere 1. Roylei, sed capsula nutante elon-

A very tall, coarse-growing species with furrowed stems, in the dried 
state so like I. Roylei, that it is impossible to distinguish them, except 
by the long capsule ofthis. My Sikkim specimens have often four lateral 
sepals. This appears to pass by numerous insensible gradations into J. 
longicornu and others. I. Thomsoni may be only a serrate state of it, 
connected by the var. 8 minor of I. sulcata. The inclined shorter cap- 
sules, which form an angle with the pedicel, best distinguish this from 
longicornu, &c. The seeds are large and eatable, as in I. Roylei. 
30. I. AMPLEXICAULIS (Edgew. Linn. Trans. xx. 37). Glaberrima, ra- 
mosa, foliis (2-4") inferioribus oppositis sessilibus oblongo-lanceolatis 
acuminatis crenato-serratis superioribus alternis amplexicaulibus ovato- 
lanceolatis, pedunculis axillaribus multifloris, sepalis ovatis acutis, la- 
bello late saccato calcare brevi, vexillo orbiculari bilobo, alis bilobis, 
capsula lineari.

Edgeworth (8. Sept.-Oct.) (v.v.) 
Affinis I. Roylei, sed facile distinguenda foliis breve petiolatis basi latis su- 
perioribus basi profunde cordato-amplexicaulibus, pedunculis brevio- 
ribus, floribus paucioribus et minoribus non confertis et capsula angusta 
non clavata.— Caulis 3-4 pedalis, 4-angularis, Edgw. 
31. I. vERTICILLATA (Wight in Madr. Journ. Sc. v. p. 15).  Glaber- 
rima, foliis oppositis verticillatisque (rarissime alternis) breve petiolatis 
lanceolatis utrinque acuminatis argute serratis serraturis infimis seti- 
geris stipulis subulatis, pedunculis elongatis erectis subumbellatim 
3-5-floris, pedicellis gracilibus, sepalis majusculis oblongo-lanceolatis, 
vexillo concavo breviter cornuto, labello cymbiformi calcare elongato 
gracillimo.
