Radix fibrosa. Caulis difFusfe rarnoslssimus, bicanaliculatus, 3 — 5-unciali.s. 

 Folia sessilia, ovato-oblonga, obtusa, inembranacea, unguicularia, basi 

 distincta; inferiora spathulata; superiora ovata. PeduncuU filiformes, 

 stricti, iiniflori, sesqui- v. tri-poUicares. Calyx profundi 5-partitus : seg- 

 mentis foliaceis, ovato-oblongis, obtusiusculis, inaequalibus ; lateralibus 

 2 dupl5 inajoi-ibus. Corolla tubulosa, azurea, calyce ter longior : /awce 

 intfis anmilo fimbriate e ciliis angustfe linearibiis acutis composito coro- 

 nata: limbo 5-lobo, erecto : foi/y ovatis, obtusis ; sinubus non productis. 

 Stamina tube inserta : jJ^t/wewto canaliculata : aHMer«? oblonga?, incum- 

 bentes, 2-loculaies. Ovarium oblongum, sessile. Stigmata obtusa, bre- 

 vissiina, minutfe papillosa. Capsula subcylindiacea, inembranacea. 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. dicfiotoma from the latter country, as to be hardly distinguish- 

 able, diflfering only in the blunt segments of its calyx, and longer corolla. 



Gen. IV. CRAWFURDIA. IFall. 



Calyx tubulosus, 5-dentatus. Corolla iafundibuliformi-campanulata, 5-loba. 



Glandulce nectarifercc 5 hypogynse. Stigmata 2, distincta, subfiliformia. 



Capsula stipitata, compressa, Crustacea, 1-locularis. Semina marginalia, 



suborbiculata, compressa, marginata. 

 Ilerboe (himalenses) perennes. Caules volubiles.' Folia opposita, petiolata, 



3 — b-nei-via. Flores axillares, magni, speciosi, coerulei v. ulbi. 

 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 Gekemium, and affords 

 a beautiful example of the intimate relationship subsisting between Gentianece 

 and Apoct/nece.
