TWO NEW TEXAS TRADESCANTIAS. 



BY B. F. BUSH. 



In a recent number of the Transactions of The Academy 

 of Science of St. Louis*, I gave an account of the Texas 

 species of Tradescantia, in which it appeared necessary 



besides enumerating 



eight 



to describe ten new species 

 others already described. It would seem that these 

 eighteen species were all that could be expected from the 

 State of Texas, and from the amount of material examined 

 I had thought the field pretty well gleaned. 



But since presenting my paper last December, I have 

 received from Mr. CD. Beadle, of the Biltrnore Herbarium, 

 three species of Tradescantia for identification, collected in 

 Texas by Mr. T. G. Harbison, one of which is T. australis, 

 but the other two I can not refer to any of the species given 

 in my paper. In order that our knowledge of the Texas 

 species of Tradescantia may be as complete as possible, I 

 append the following descriptions of these two species : 



• 



Tradescantia Harbisoni Bush,sp. nova. 



Stems short, slender, weak, 1 to 2 dm. long, 



much 



branched at the base, decumbent or ascending, densely 

 white-woolly throughout with long spreading white hairs, 

 dark yellowish-green; leaf-blades linear-lanceolate, flat, 

 thin, long-hairy on both sides, 1 to 2 dm. long, 6 to 10 

 mm. wide, one on each stem; sheaths almost none, very 

 loose and thin, beautifully nerved and rose-colored, hairy 

 like the leaves; bracts of the involucre 2, unequal, broader 

 than the leaves, 8 to 15 mm. wide, broadest below the 

 middle, the longer one 1 to 1.5 dm. long, thin, flat, hairy 

 like the leaves, tapering to a blunt point, beautifully 

 nerved and rose-colored at the thin papery bases ; cymes
