 ata Less. of Brazil, and often confounded with V. arborescens 

 Sw. of Central America.

 cept more or less pubescence in the inflorescence which forms 

 large pyramidal clusters of more Qr less leafy panicles: leaves 

 oval, tapering at both ends and petioled, upper ones often 

 narrower, entire or obscurely toothed: involucral scales in 

 five or six rows, innermost ones linear-oblong and often quite 

 .elongated, the outer ones gradually passing into much broader 

 and shorter forms, all sharp pointed and membranous except 

 for the greenish center and tip: heads 3 or 4'flowered, 

 cylindrical, more or less pedicellate: achenes strigose pubes- 

 cent, often denselyso. — Santa Rosa, Depart. Santa Rosa, alt. 

 3-4.000^ April 1892, Heyde & Lux 3,421.
