-Radix fibrosa. Caulis diffusé ramosissimus, bicanaliculatus, 3—5-uncialis. 
Folia sessilia, ovato-oblonga, obtusa, membranacea, unguicularia, basi 
distincta; inferiora spathulata; superiora ovata. Pedunculi filiformes, 
stricti, uniflori, sesqui- v. tri-pollicares. Calyx profundé 5-partitus: seg- 
mentis foliaceis, ovato-oblongis, obtusiusculis, inzequalibus; lateralibus 
2 dupld majoribus. Corolla tubulosa, azurea, calyce ter longior: fauce 
intüs annulo fimbriato e ciliis angusté linearibus acutis composito coro- 
nati: limbo 5-lobo, erecto: lobis ovatis, obtusis; sinubus non productis. 
Stamina tubo inserta: filamenta canaliculata: anther oblongae, incum- 
bentes, 2-loculares. Ovarium oblongum, sessile. Stigmata obtusa, bre- 
vissima, minute papillosa. Capsula subcylindracea, membranacea. Se- 
mina parva, subrotunda, fulva, punctis excavata. 
This affords another striking example of the great similarity that prevails 
between the vegetation of the Himalaya and that of Siberia. It comes so 
very near to E. dichotoma from the latter country, as to be hardly distinguish- 
able, differing only in the blunt segments of its calyx, and longer corolla. 
Gen. IV. CRAWFURDIA. Wall. 
Calyx tubulosus, 5-dentatus. Corolla infundibuliformi-campanulata, 5-loba. 
Glandule nectarifere 5 hypogynae. Stigmata 2, distincta, subfiliformia. 
Capsula stipitata, compressa, crustacea, 1-locularis. Semina marginalia, 
suborbiculata, compressa, marginata. 
Herb: (himalenses) perennes. Caules volubiles! Folia opposita, petiolata, 
3—5-nervia. Flores axillares, magni, speciosi, cerulei v. albi. 
In structure this genus comes near to Pneumonanthe, but differs in its 
twining habit, filiform stigmas, and compressed orbicular seeds attached to 
the margin of the valves. It has entirely the habit of Gelsemium, and affords 
a beautiful example of the intimate relationship subsisting between Gentianec 
and Apocynee, 
1. C. speciosa, foliis ovatis acuminatis 5-nerviis, pedunculis solitariis subnudis, 
dentibus calycinis abbreviatis, capsula ellipticà stipite breviore.
