1809. Fig. 2, B. 



Datura gardneri Hook. Curtis's Bot. Mag. sub pi. 4252. 1846. 

 Type: A cultivated plant, erroneously stated to be of Mexican origin. 

 Range: Provinces of Minas Geraes and Sao Paulo, Brazil; now much 



cultivated in the tropics and in conservatories; common in the Antilles. 



The native country of this species, distinguished from all others by its co- 

 herent anthers and relatively short, much inflated, 5-toothed calyx, was long 

 doubtful, and its fruit has remained undescribed. Fruiting specimens in the 

 U. S. National Herbarium were collected near Caldas, in the province of 

 Minas Geraes, not far from the boundary of Sao Paulo, May 12, 1873, by 

 Dr. Anders Frederik Regnell of that city, and presented by him to the Bo- 

 tanical Museum of Upsala. The 2-celled fruit (Fig. 2, B) is spindle-shaped, 

 12 to 12.5 cm. long, 2.5 cm. in diameter at the middle, gradually tapering to- 

 ward each end. It is devoid of all vestige of calyx and is borne on a recurved 

 peduncle 7 cm. long. The dry brown pericarp is thin and fragile, glabrous, 

 and longitudinally veined with delicate raised nerves. The large irregular 

 angular seeds are closely packed in the two cells.
