DESCRIPTIONS OF THREE NEW BRASILIAN VERNONIACE^. 203 



9-12 lines long. Leaves alternate, oblong, acute orbluntish, cune- 

 ately narrowed at the base, 2^-3 inches long, l-l^ inch broad at the 

 middle, distinctly toothed, subcoriaceous, green and glabrous above, 

 obscurely grey-canescent beneath. Heads crowded in dense terminal 

 panicles 3-6 inches broad, with corymbose-scorpioid branches clothed 

 with thin grey tomentum, the upper heads sessile, the lower on pedi- 

 cels 1-2 lines long. Heads 4 lines deep, consistingof 12 to 16 florets, 

 enclosed in a campanulate involucre 2 lines deep, and broad, made 

 up of dry pale brown scales closely imbricated in about four rows, 

 the inner oblong and blunt, the outer deltoid, all about half a line 

 broad, slightly pilose on the back, and the edge ciliated. Achenes 

 cylindrical pilose, not seen fully mature. Pappus | inch deep, 

 of copious biserial distinctly ciliated brownish white bristles, the 

 outer about a sixth as long as the inner. Corolla I inch deep, the 

 upper half a narrow funnel, with linear teeth a line long. 



Hab. — Rio Janeiro, Glaziou, 7705 ! Of known species it only 

 comes near V. polyantlios, Less., from which it differs by its shorter 

 broader leaves, larger capitula, blunter scales, fewer flowers in a 

 head, many heads peduncled, and much larger pappus and corolla. 



5* PiPTocARPHA TOMENTosA, Btther, fi. sp. Brauchlets stout, matted 

 with brown tomentum. Petioles |-f inch long, channelled down the 

 face. Blade oblong-lanceolate, acute or acuminate, cuneately nar- 

 rowed to the base, or veiy slightly rounded at the very base, entire 

 or distinctly dentate, 3-4 inches long, 1-1^ inch broad at the middle, 

 very coriaceous in texture, glabrescent when mature above, matted 

 with thick brownish-white persistentjtomentum below, through which 

 only the main veins appear. Heads in dense crowded sessile clusters, 

 the internodes so short that these form a continuous mass three or four 

 inches long some distance down the branch. Involucre campanulate, 

 I inch deep, composed of several rows of thin brown scariose close 

 imbricating scales, nearly | inch broad, which, as in the other species, 

 fall away very readily, the. outer deltoid, the inner lanceolate, the tips 

 of all and the whole of the outermost matted with tomentum. Florets 

 about 8 to a head. Achenes 2 lines long, cylindrical, quite naked. 

 Pappus ^ inch long, composed of flexible dirty-white bristles, the 

 outer row about a quarter as long as the inner. Corolla purple, 

 glabrous, ^ inch long, the upper half funnel-shaped, slit half way down 

 into 5 linear teeth. 



Hab. — Eio Janeiro, Glaziou, 7719 ! Of known species only near 

 P. axillaris, from which the dense tomentum of the branches and lower 

 side of the leaves marks it at a glance. 



6*. PiPi'ocARPHA PANNosA, Baker, n.sp. Branchlets woody, terete, 

 ^ inch thick, densely clothed with pale brown, soft, short, spreading 

 woolly pubescence. Petioles an inch or more long, clothed with pu- 

 bescence like that of the stem. Leaves oblong entire, 6-8 inches long, 

 2-22- inches broad at the middle, acute, cuneate, or slightly rounded 

 at the often unequal'.base, coriaceous in texture, glabrescent when ma- 

 ture except on the midrib above, densely matted with persistent whitish 

 tomentum below, which is thicker and more woolly on the midrib. 

 Capitula 4-10 in dense axillary sessile umbels. Involucre 4 lines deep, 

 funnel-shaped, made up of about four rows of closely imbricated scales, 

 which are dry, hard, and pale brown, ^ inch broad, only matted a little
