LOGANIA FAMILY. 



Herbs, shrubs, vines or some tropical genera trees, with opposite or verticil- 

 late simple stipulate leaves, or the leaf-bases connected by a stipular line or 

 membrane, and regular perfect 4~5-parted mostly cymose or spicate flowers. 

 Calyx inferior, the tube campanulate, sometimes short or none, the segments 

 imbricated, at least in the bud. Corolla gamopetalous, funnelform. campanu- 

 late, or rarely rotate. Stamens as many as the lobes of the corolla, alternate 

 with them, inserted on the tube or throat; anthers 2-celled, the sacs longitudin- 

 ally dehiscent; pollen-grains simple. Disk usually none. Ovary superior, 2- 

 celled (rarely 3~5-celled); style simple, 2-5-cleft or 2-divided, rarely 4-cleft; 

 ovules numerous or few in each cavity, anatropous or amphitropous. Fruit a 

 2-valved capsule in our species. Seeds winged or wingless; embryo small, 

 usually straight; endosperm copious; cotyledons narrow or foliaceous; radicle 

 terete or conic. 



About 30 genera and 400 species, widely distributed in warm and tropical regions. 



Style 4-cleft; woody vine: flowers large, yellow. i. Gelsemiinn, 

 Style simple, 2-lobed or 2-divided with a common stigma; herbs. 



Corolla-lobes valvate; capsule didymous or 2-lobed; leaves broad. 



Style simple, jointed; spike simple. 2. Spigelia. 



Style a-divided below; spikes cymose. 3. Cynoclotunn. 



Corolla-lobes imbricate; capsule subglobose; leaves linear. 4. Polypremum. 



i. GELSEMIUM Juss. Gen. 150. 1789. 



Glabrous twining woody vines; leaves opposite, or rarely ternatc, their bases connected 

 by a stipular line; flowers large, yellow, in axillary and terminal nearly sessile cymes, the 

 pedicels scaly-bracteolate. Calyx deeply 5 parted, the segments dry, imbricated. Corolla 

 funnelform, with 5 broad lobes imbricated in the bud. Stamens 5, inserted on the tube of 

 the corolla; anthers linear-oblong. Ovary oblong, 2-celled; style slender or filiform, 4-cleft, 

 the lobes stiguiatic along the inner side; ovules numerous in each cavity, on linear placentae. 

 Capsule elliptic, flattened contrary to the partition, septicidally dehiscent, the valves boat- 

 shaped, 2-cleft at the summit; seeds several in each cell, flattened, winged. [From the 

 Italian Gelsomino, the Jessamine.] 



Two known species, the following of the southeastern United States, the other of eastern Asia.
