 American Plants. By J. Torrey. 



Macranthera Lecontii, Plate 4. 



Segments of the calyx entire, linear-lanceolate, scarcely one- 

 third the length of the corolla. 



Root perennial. Stem herbaceous, from two to three feet high, 

 simple, somewhat pubescent, obtusely quadrangular. Leaves nearly 

 smooth on both sides ; lower ones ovate-lanceolate, opposite, petiolate, 

 pinnatifi.lly lobed, with the segments entire or toothed; the upper ones 

 oval, coarsely toothed ; those at the base of the peduncles quite entire. 

 Flowers, in a terminal raceme, erect. Peduncles about an inch long, de- 

 clined at the base, and curved upward towards the summit. Calyx sub- 

 campanulate, deeply cleft; segments nearly equal, linear-lanceolate, 

 from one-fourth to one-third the length of the corolla, acute. Corolla 

 deep yellow, an inch long and 2 — 3 lines in diameter, somewhat cylin- 

 drical and incurved, of a thick and pretty firm texture ; border 5-toothod ; 

 the segments ovate-oblong, spreading. Stamens nearly equal, at first 

 included, but at length much exserted, scarcely declined; filaments 

 woolly, rather thick; anthers about 3 lines long, linear, sagittate at 

 the base, somewhat cohering, woolly. Ovary ovate, acute, 2-celled, 

 many-seeded. Style very long and slender. Stigma simple, very mi- 

 nute. Capsule short, ovate, acuminate. 



IIab. In dry pine woods on the Alatamaha, in Liberty 

 County, Georgia. Major Le Conte ! In bogs, Middle Florida, 

 Dr. Chapman ! Flowers in September. 



Obs. This plant was discovered about seven years ago by 

 Major Le Conte, from whom I received specimens marked, 

 "A new genus, allied to Gerardia." I proposed for it the 

 name Macranthera, but refrained from publishing it, in the ex- 

 pectation that the discoverer himself would describe it, which 

 however, he declined doing, kindly permitting me the favour 

 of making known to botanists this interesting addition to our 

 Flora.
