l)y the natives of Quito. A specimen in the U. S. National Herbarium (no. 

 1,023,042) was collected in the garden of the American Legation at Quito in 

 October, 1010, by Dr. J. N. Rose, who also obtained seeds (No. 28,553) and 

 a photograph. 



Lagerheim says that it may be identical with Datura chlorantha Hook.*^ 

 but this is impossible. Hooker's plant does not belong to the section Briig- 

 mansia. It is a form of the Old World Datura metel fastuosa, the double 

 flowers of which are borne on a short, thick, erect peduncle, although inverted 

 in the illustration, and the calyx is 5-toothed like that of Datura metel L. 

 Typical specimens of D. chlorantha were seen by the writer during a recent 

 visit to the Island of Hawaii, growing by the roadside on the west coast of the 

 Island. The flowers were of a greenish yellow color, identical in form with 

 that figured by Hooker, and the fruit a prickly indehiscent capsule subtended 

 by the enlarged persistent base of the calyx. The habit of the plant was 

 low and spreading, as in the description of the Australian plant quoted by 

 Hooker, not at all tree-like as in the section Brugniansia. 



22. Datura pittieri Safford, sp. nov. Fig. 2, C. 



vShrub or small tree with ovate-lanceolate acuminate entire leaves unequal 

 at the base, sparsely hairy when young, at length glabrous or nearly so, 17 

 to IS cm. long, 7.5 cm. broad, on glabrous petioles 2.5 cm. long; calyx spathe- 

 like, more than half the length of the corolla (10 cm. long), glabrous, termin- 

 ating at the apex in 2 obtuse teeth; corolla IS cm. long, the tuTje narrow below, 

 subcylindric and 2.5 cm. broad above the middle, the limb flaring and trum- 

 pet-like, 6 cm. in diameter, bearing 5 very long caudate teeth, about 4 cm. 

 long, not revolute but curving inward; pistil 14 cm. long, the style slender 

 and thread-like, the stigma short and thick, about 7 mm. long; stamens 13.5 

 cm. long, the anthers free, linear, 26 mm. long; fruit (Fig. 2, C) elongate ovoid, 

 IT, cm. long, 5.5 cm. thick, devoid of terminal nipple or beak, terete, 2 -celled, 

 the cells closely packed with irregularly angled oblong seeds; pericarp thick, 

 glabrous. 



Type in the U. S. National Herbarium, no. 531,502, collected in the vicinity 

 of Huila, an Indian village in the Rio Paez Valley, Tierra Adentro, Colombia, 

 at an altitude of 1600 to 1900 meters, Januar}^, 1906, by Henri Pittier (no. 

 1305). Fresh fruit photographed by Professor Pittier; negative no. 8708,

Brtigmansia hicolor Pers. Syn. PI. i: 216. 1805. 



Type Locality: "Habitat in altis, frigidis et ruderatis locis provinciarum 



Tarmac, Xauxae, Huarocheri, Cantae, et Huamalies." 

 Range: Andes of Peru and Ecuador; now much cultivated in tropical and 



subtropical countries. 



This red-flowered tree datura was collected in 19 15 by Mr. O. F. Cook in 

 the Andes of Peioi, attaining its perfection at an altitude of 12,000 feet, where 

 there is frost every night. In his field notes Mr. Cook describes Datura 

 sanguinea as a woody species, forming a tree somewhat smaller than D
