A native of the Province of Minas Geraes, in Brazil. 
Shrubby, attaining a height of four or five feet, with copiously- 
branched woody main stems, the ultimate branches a quarter of 
an inch thick, densely ferrugineo-tomentose, winged to a breadth 
of one and a half line to two lines, densely armed with formidable 
prickles, which are woody in texture, very much compressed late- 
rally, deltoid-cuspidate, slightly hooked towards the point, the 
largest half an inch long and as broad at the base. Leaves ovate- 
oblong, six or eight inches long by half as broad, pinnatifid half- 
way down to the midrib in the lower two-thirds with bluntish 
ovate-deltoid lobes, the base narrowed into the wings of the stem, 
texture herbaceous, the upper surface green and softly pubescent, 
the lower clothed with loose orange-ferruginous tomentum, the 
principal veins on both sides armed with sharp straight prickles. 
Flowers in close scorpioid cymes of about a dozen flowers each, on 
firm woody peduncles one or two inches long, which, like the short 
pedicels and calyx, are clothed with orange-ferruginous tomentum. 
Calyx eight or nine lines long, the teeth lanceolate, reaching 
more than half-way down. Corolla-segments ovate, white with a 
slight tinge of green, equalling the calyx; the bright orange- 
yellow stamens two-thirds as long. Ovary subglobose, woolly ;
