Family 14. LOGANIACEAE Dumort. Anal. Fam. 21. 1829. 



LOGANIA FAMILY. 



Herbs, shrubs, vines or some tropical genera trees, with opposite or verticillate 

 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, campanulate, 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 longitudinally 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. Gelsemium. 

 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 2-divided below ; spikes cymose. 3. Cynoctonum. 



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



i. GELSEMIUM Juss. Gen. 150. 1789. 



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

 by a stipular line, the very small stipules deciduous ; 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 stigmatic 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 typical one of the southeastern United States, the other of 

 eastern Asia.
