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-pauiculate ; peduncles 4 to 6 cm. long ; pedicels 

 0.5 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 

 5.5 cm. 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, 30 April, 1898, no. 

 6806 ; and by Dr. Edward Palmer in the vicinity of Acapulco, October, 

 1894, to March, 1895, no. 570 (distributed as Ruellia ? ovcdifolla, 

 Hemsl. ex char. ?) ; also by Botteri at Orizaba, in herb. Gray without 

 number. 



A species having its affinity apparently with R. d'qjter acanthus, Hemsl., 

 and R. tuherosa, 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, when 

 moistened, is more or less spreading and almost velvety, hence the specific 

 name. 



Randia 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 cm. 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.
