GREENMAN. — MEXICAN PHANEROGAMS, 573 
rete or obtusely 4-angled, glabrous or sparingly villous: leaves opposite, 
oblong-lanceolate, including the narrow less villous petiole 5 to 13 cm. 
long, 1 to 3 cm. broad, acuminate, acute or the lower obtuse or even 
rounded at the apex, narrowed at the base into a petiole, entire or sub- 
repand, densely lineolate on either surface, and with a few scattered 
villous hairs on the midrib and margins, especially towards the base: 
inflorescence cymose-paniculate; peduncles 4 to 6 cm. long; pedicels 
) to 1.5 cm. long; bracts and bracteoles lance-linear, 1 cm. or less in 
length: calyx deeply and regularly 5-parted; tube 2 to 4 mm. long; 
divisions linear-attenuate, 1 to 2 cm. long, these as well as the pedicels 
densely lineolate and stipitate-glandular, not hirsute: corolla purple, 4 to 
em. long, tubular-funnelform, externally puberulent; tube slender 
below, ampliated above; lobes subrotund, 1.5 cm. or more broad: mature 
capsules 2.5 to 3.cm. long, glabrous, about 15-seeded; seeds slightly 
oblique, 3 mm. broad, flattened, canescent. — Collected by C. G. Pringle 
in lowlands near Tampico, State of Tamaulipas, 80 April, 1898, no. 
6806; and by Dr. Edward Palmer in the vicinity of Acapulco, October, 
1894, to March, 1895, no. 570 (distributed as Ruwellia? ovalifolia, 
Hemsl. ex char.?); also by Botteri at Orizaba, in herb. Gray without 
number, 
A species having its affinity apparently with 2. d ‘siietionnthus, Hemsl., 
and FR. tuberosa, L., but differing from the former by inflorescence and 
longer corolla, also by the character of the calyx, and from the latter by 
the foliar characters. The seeds of this plant in the dried state are cov- 
ered with an appressed canescent pubescence, which however, wheu 
moistened, is more or less spreading and almost velvety, hence the specific 
name. ‘ 
? a canescens. Shrub or small tree, 3 to 5 m. high: stems 
terete, covered with a grayish bark: spines 5 to 10 mm. in length: leaves 
broadly obovate, 1 to 1.5 em. long, nearly as broad, abruptly narrowed 
below into a short petiole or subsessile, rounded or obtuse at the apex, 
canescent-pubescent on either surface: flowers solitary, terminating short 
axillary branches: calyx-tube about 4 mm. long, appressed-canescent- 
pubescent; lobes linear, acute, about equalling the tube, grayish-pubes- 
cent: corolla salverform; tube nearly 1 cm. long, somewhat folded on 
itself near the middle, externally pubescent, internally glabrous: lobes 
somewhat thickened, broadly ovate, about 6 mm. long, nearly as broad, 
obtuse or rounded at the apex, glabrous above, ciliate: fruit not seen. — 
Collected by C. G. Pringle in barrancas near Cuernavaca, State of 
Morelos, altitude 1,500 m., 28 May, 1898, no. 6863.
