arborea, from which it differs not only in the color and form of its flowers, but 

 also in its more open habit and its narrower foHage; leaves narrowly oblong, 

 tapering at each end, i8 cm. long and 5 cm. broad, the upper ones entire or 

 slightly repand, puberulent, the petiole 8 cm. long; peduncle 3 to 4 cm. long, 

 puberulent; calyx 9 cm. long, less than half the length of the corolla, inflated, 

 terminating in two obtuse teeth; corolla glabrous, about 25 cm. long, the 

 tube green from the base to beyond the end of the calyx, then light yellow, 

 followed by red on the upper part including the limb and the teeth, the red 

 portion having prominent longitudinal yellow nerves; diameter of the limb 

 (including the teeth) 11 cm.; style 18-20 cm. long (shorter than the corolla 

 tube), terminating in a thick knob-like stigma, slightly exceeding the stamens; 

 anthers distinct, hairy, broadly linear, 25 mm. long; fruit broadly ovate or 

 turbinate, 9 cm. long, 6 cm. thick at its greatest diameter, terminating in an 

 obtuse nipple, the greater part enveloped in the split persistent husk-like 

 calyx. Specimens in the National Herbarium (no. 1,022,006) collected at 

 Ambato, Ecuador, in 1918, by J. N. Rose (no. 22,344) agree in all respects 

 with those collected in Peru by Mr. Cook. Photographs of the flowers and 

 fresh fruit, natural size, made by Mr. Cook in the field, will appear in the 

 writer's forthcoming paper to be published in the Smithsonian Annual Re- 

 port.

Shrub or small tree with short leafy branches, the younger growth densely 

 clothed with whitish spreading hairs ; leaves ovate-oblong, obtuse, repand and 

 sinuate, with short obtuse lobes, copiously clothed on both sides by soft 

 whitish hairs, 5 to 23 cm. long, 2.5 to 12.5 cm. broad, the base rounded and 

 often unequal, the upper ones angular-toothed and densely to mentose ; petioles 

 2.5 to 7.5 cm. long, stout, densely subtomentose-pilose ; flowers solitary, 

 pendulous; peduncles about 2.5 cm. long, densely subtomentose-pilose; calyx 

 densely pubescent, ventricose, less than half the length of the corolla, 7.5 to 

 9 cm. long, terminating at the apex in 2 to 5 obtuse teeth; corolla funnel- 

 shaped, 15.5 to 18.5 cm. long, pubescent, orange or saffron-colored, with 15 

 prominent longitudinal green nerves; limb 6 to 6.5 cm. broad, divided into 

 5 obtuse spreading lobes each terminating in a recurved tooth 10 to 15 mm. 

 long, the margin of limb emarginate or notched between the lobes; pistil 

 slightly exceeding the corolla tube, 16.5 to 19.5 cm. long, terminating in a 

 thickened obtuse stigma; stamens 5, equaling the corolla tube or very slightly 

 exserted, the anthers closely associated round the style, hairy, 1.25 to 1.5 cm. 

 long; fruit (Fig. 2, D) ovoid, pubescent, about 7 cm. long, 4.5 cm. in diameter,
