84 NEOPHYTON 



dichotome, leaves ovate acute undulate ciliate, 

 flowers racemose secund. — Texas and Louisi- 

 ana, fine plant 3 feet high, leaves 2 or 3 inches 

 long, flowers large blue, the 3 petals are quite 

 evanescent, lasting only one hour expanded to- 

 wards noon, but the calix is persistent as in 

 Tradescantia. See in fl. tellur. my reform of 

 the Genera blended in Tradescantia ; without 

 attempting to give a complete Monograph of 

 our real Tradescantias (which now amount to 

 about 15 species:) I shall here chiefly enu- 

 merate my new species and varieties. 



451. Tradescantia Virginica L. this well 

 known linnean sp. may be known by the lan- 

 ceolate smooth leaves, long foliose involucre 

 of multiflore umbels and villose calix ; but so 

 many sp. and var. are blended with it in gar- 

 dens and herbals that it is needful to attend to 

 many other differences, as will be seen below 

 in my New sp. 



452. Trad, Vircrinica Var. alba. Hooker 

 b. m. 3501. this white flower variety is not my 

 Tr, ohiensis. 



453. Trad, ohiensis Raf. precis 146. Leaves 

 flat linear acute smooth, umbel multiflore, in- 

 volucre longer than flowers, calix smooth. — In 

 Ohio, flowers white, described in 1814 from a 

 specimen of Dencke given me by Vanvleck, but 

 I have not met it in Ohio, and it may be a var. 

 of my Tr. levie-ata. 



454. Trad, mrginica Var, purpurea Raf. 

 differ by leaves narrow^ lanceolate, (> to 10 in- 

 ches long, umbel pauciflore ^-^^. petals purple 

 — seen only in gardens, not met spontaneous, 

 yet probably a peculiar sp. Tr, purpurea. 



455. Trod, virgin var, harhata Raf. differ 

 by umbel, pauciflore 5-6fl. calix smooth except
