RUBIACEAE 249 



There are two species in this genus, one native in Japan, the 

 other in eastern North America. 



CAMPSIS RADiCANS (Linnaeus) Seemann 

 Trumpetcreeper Trumpet-Flower 



The Trumpetcreeper, fig. 65, is a large, long, twining vine 

 with stems often as much as 3 and 4 inches in diameter and with 

 glabrous branches, which bear pinnately compound leaves oppo- 

 sitely arranged and on petioles 1 to 2 inches long. There com- 

 monly are aerial rootlets opposite or just below each leaf on 

 the stem. There are 7 to 13 ovate to lanceolate leaflets per 

 leaf, the individual leaflet measuring 3 to 7 inches long and 2 

 to 3 inches wide. The terminal one usually is long stalked and 

 the lateral ones are shorter stalked or nearly sessile. The 

 leaflet margins are very coarsely serrate, and the blades are 

 acuminate at the apex and mostly narrowed or sometimes squar- 

 ish but definitely asymmetrical at the base. The surface is 

 smooth above but usually more or less pubescent beneath, espe- 

 cially on the midrib. 



The trumpet-shaped flowers, which appear early in June and 

 all through the summer, are reddish orange, showy, and as much 

 as 2 inches long. The fruit, which begins to mature in late 

 August, is a 2-celled capsule flattened at right angles to its par- 

 tition, which measures from' 4 to 10 inches in length by ^ to 1 

 inch in diameter. It contains numerous flat seeds with tissue- 

 like wings, which are eroded on the edges. 



Distribution. — The Trumpetcreeper, normally a vine of 

 moist woods and thickets, ranges from New Jersey to Iowa 

 and south to Florida and Texas. It is impossible to say what 

 its original range in Illinois may have been, since it has been 

 spread widely into cultivated grounds and in many parts of 

 the state is now a troublesome weed. It grows abundantly as 

 a hardy and w^ell-naturalized vine as far north as Peoria and 

 Henderson counties.
