Tribe IV. 



GELSEMIE'.<E. Fruit of 2 joined follicles, which are at 

 length separable, 2-valved, 2-ceIled ; valves 1-celled, with in- 

 flexed, seminiferous edges, which constitute the dissepiment. 

 Seeds flat, winged. This tribe seems to connect the Gentianeae 

 with Apocynea, through Cramfurdia.

 Stigma trifid. Capsule ovate-oblong, rather compressed, 2- 

 celled, composed of 2 joined follicles, which are separable, fur- 

 rowed in the middle ; 2-valved ; valves keeled, with inflexed 

 edges, which constitute the dissepiment. Seeds numerous, flat,
