Catlicart's collection of what a})pears to be a very pale-flowered variety 

 of it, and which has four lateral sepals.

 Species insignis 1-4 pedalis, J. spirifer affinis et similis, sed caules ro- 

 bustiores, folia majora, argute dentata v. serrata, basi ciliata (rarius 

 nuda), petiolus ssepissirae glandulosus, pedunculis brevissimis, bifloris, 

 bractese elongatse tortse, et calcar hamatum non circinatum. — Cap- 

 sula linearis, poUicaris. Semina pauca, orbicularia, opaea, granulata. 

 Folia inferiora saepius non glandulosa. 



The long, subulate, twisted bracteoles of this species are quite peGuliar 

 to it ; in other respects it resembles I. spirifer, &c. It is veiy common 

 in the Khasia mountains, and is probably distributed amongst Wallich's 

 plants, though I have failed to recognize it amongst the Linnean Society's 

 collections, Henslow's, Benthara's, or those of Kew. In some of my 

 Sikkim specimens there are foiu* lateral sepals, as there are also in that 

 figured by Cathcart's artists ; in others only two. 



b. Capsula brevis v. ignota. 



63. I. DISCOLOR {De Prodr. i. 687 ; Wall. Cat. 4767). Caule erecto 

 subramoso, foliis petiolatis 1-2'' ovatis acuminatis eglandulosis grosse 

 crenato- serratis supra pilosulis, pedicellis breviusculis 2-floris, bracteis 

 parvis late ovatis dissitis, floribus magnis, sepalis parvis ovatis acumi-

Caulis 3-5 pedalis. Folia membranacea, majora et latiora quam in I. 

 elegans et arguta. Peduncidi gracillimi, foliis breviores, arcuati, iis 

 I. longipes et urticifolia similes, sed breviores, pedicellis capillaceis. 

 Flores \\" longi. Capsules lineari-clavatae, immaturae ? 



I. urticcefolice simillima et forsan ejus varietas, sed bracteae breviores
