pubescent. Leaves elongated, oblong-lanceolate, entire or 
glandular-toothed, rather few on the stems; flowers few, 
3 to 9, scattered along the stem, 2.5-5 cm. apart; sepals 
densely pubescent and bristly with long white hairs; co- 
rolla azure blue, about 3 cm. long; tube more than twice 
as long as the sepals; hypanthium densely hispid with long 
bright white hairs. 
Sandy swamps near the coast, Florida to Texas. Summer

This is evidently related to ZL. puberula Michx., but 
differs conspicuously from that species in the taller, more 
slender, simple stems, longer leaves, and especially i in the 
fewer flowers, which are much larger.

XANTHIUM BUBALOCARPON Nl. sp. 
Stems very stout, much branched and spreading, about 
one meter tall. Upper part of the stem and the petioles 
very rough, covered with stout white papillae; petioles 
5-15 cm. long, stout; leaf blades broadly triangular, 
8-20 cm. wide, 3- to 5-lobed, dentate, very thick, rough-scab- 
rous on both surfaces ; burs pubescent, ovoid, clustered in the 
axils of the upper leaves, and in terminal racemose clusters, 
2.5-4 em. long, including the short beaks, 2-3 cm. wide, 
including the prickles, the short hispid beaks 6-8 mm. 
long, nearly straight, hooked at the apex, equalling or a 
little shorter than the very dense subulate, slightly uncinate 
prickles, which are about one-third as long as the diameter 
of the bur, and hispid nearly to the middle with yellowish- 
brown hairs, the prickles and the pubescence usually 
entirely concealing the body of the bur.
