A shrub about 5 m. high, with ovate-lanceolate, acuminate, strigose 

 leaves, few flowered, axillary cymose, strongly bracteate inflorescence, the 

 flowers with densely long-strigose-hirsute calyces, and glabrous 3-celled 

 ovary. Branches brown, more or less strigose. Leaves membranous, 9 

 to 18 cm. long, 3 to 7 cm. wide, both surfaces beset with scattered, 

 brown, strigose hairs, those beneath, especially on the nerves, longer than 

 those above, the margins irregularly spinulose-serrate, the base acute, 

 roxmded or subcordate, the apex short acuminate; nerves about 12 on 

 each side of the midrib, prominent beneath; petioles 1 to 1.5 cm. long, 

 strigose. Inflorescence 4 to 8 cm. long, strigose, the peduncle 2 to 4 cm. 

 long, the flowers subumbellate, few, 3 to 8, crowded, the branches, branchlets, 

 and pedicels subtended by ovate to ovate-lanceolate bracts and bracteoles 

 1 to 2.5 cm. long, giving the appearance of an involucre subtending the 

 flowers. Flowers white, odorless, about 1 cm. long. Sepals 8 mm. long, 

 the three outer ones oblong-ovate, acute, densely strigose, the stiff bristle- 

 like hairs 2.5 to 3.5 mm. long, the inner two oblanceolate, glabrous except 

 for a few bristles on the median portion below. Petals 5, membranous, 

 glabrous, obovate, irregularly, strongly sinuate-emarginate, undulate, 10
