because the original description agrees very well with the speci- 

 mens I have collected in the Southern States and the original lo- 

 cality lies within the bounds of the range shown by my specimens. 

 The plant is usually glabrous except a more or less distinct tuft ot 

 hairs near the apex of the sepals. 



6. Tradescantia hirsuticaulis n. sp. 



Perennial by a cluster of coarse elongated (1-2.5 dm.) roots, 

 slender, hirsute throughout with long brownish hairs, or par- 

 tially glabrous above, otherwise bright green. Stems several to- 

 gether, erect or nearly so, 3-4 dm. tall, leafy throughout, densely 

 hirsute, simple; leaves narrowly linear, 2-3 dm. long, more or less 

 curved, involutely folded, less densely hirsute than the stem ; 

 sheaths rather pale, 1-2.5 cm. long, conspicuously ribbed; in- 

 volucre of two linear very unequal leaf-like bracts which are some- 

 what smaller than the stem leaves ; pedicels slender, 2-2.5 cm. 

 long; flowers purple, large, 2.5-3 cm. broad; sepals variable in the 

 same flower, ovate or lanceolate, 9-15 mm. long, rather villous 

 and somewhat glandular ; petals suborbicular, broader than long 

 and undulate ; mature capsule not seen, 



Sandy places, Georgia to Florida; occurs at 400 meters on Stone 

 Mountain. May to July. 



Florida: Chapman, Wood ; Georgia: Stone Mountain, Small. 

 A very distinct and beautiful species related to Tradescantia reflexa 

 but much more slender in habit. Remarkable for the abundant 

 development of brownish hirsute pubescence on the stem, leaves 

 and inflorescence. The flowers are larger and of a deeper blue 

 than those of Tradescantia reflexa. 



7. Tradescantia longifolia n. sp. 



Perennial by a short rootstock and slender roots which are 

 I dm. or rarely 2 dm. long; rather slender, glandular pilose, dull 

 green. Stems solitary, erect or assurgent, 4-5 dm. tall, strict, 

 simple or sparingly branched above, densely glandular; leaves 

 linear or nearly so, chiefly basal or confined lo the lower part of 

 the stem, 2-4 dm. long, even the lower ones surpassing or almost 

 equalling the stem, gradually narrowed from near the base, flat, 

 densely glandular-pilose like the stem; sheaths 2-2.5 cm. long, 

 ciliate with long hairs, imbricated below ; involucre of two small 

 leaf-like bracts, or one often almost wanting; pedicels stoutish, 

 1.5-2 cm. long; flowers deep blue, 2.5-3 cm. broad; sepals linear- 

 lanceolate or linear-oblong, i cm. long, obtuse, 1 1^^ to 2 times 

 shorter than the pedicels ; filaments at length as long as the sepals,
