Description. &c.— A magnificent plant, growing four feet or five feet high, with a round stem, which is 
hom-shaped at its extremities. The flowers are very large, white stained with purple, and sweet-scented. The 
capsule is smaller than in most of the other species, and not thorny. It is a native of Mexico, whence it was 
introduced in 1805 ; and it has also been found in Cuba. The culture is the same as that of D. Tatula. 
OTHER SPECIES OF DATURA. 
D. FEROX, Lin. 
Closely resembling D. Stramonium, except in the capsule being furnished with much larger and stronger 
prickles. A native of Cochin-China and Nepaul, introduced iu 1731. 
D. QUERCIFOLIA, H. B. et Kunth. 
Nearly allied to D. Tatula, but with the leaves shaped like those of the common oak. The whole plant is 
slightly hairy. A native of Mexico, in the most temperate climates, and consequently quite hardy in England. 
Seeds may be had at Charlwood's, and they should be sown in the open border in March or April. 
D. MURICATA, Berntt. * 
Flowers long and white ; capsule warted ; but not prickly. Introduced in 1820, and supposed to be a native 
of the East Indies. 
D. GUAYAQUILENSIS, //. B. et Kunth. 
Very nearly allied to D. Metel, of which it is probably a variety. The flowers are white, and the stem and 
leaves downy. A native of humid places near Guayaquil, introduced in 1820. Seeds may be had at Charlwood's. 
There are several other annual species of Datura, natives of South America, which have not yet been 
introduced. All the species are very handsome, and of very easy culture. The shrubby or tree species are 
now formed into a genus called Brugmansia, from several botanical differences in the flower and its calyx, and 
from the fruit of the Brugmansia being always smooth, while that of the Datura is generally prickly. All the 
species are poisonous ; and it is probably from this circumstance, united to the beauty of the flowers, that the 
Datura is considered in floral language to represent deceitful charms. The word Datura is said to be a corruption 
of Tatorah, the Arabic name of one of the species. Metel and Tatula are the names of the plants so called, in their 
native countries. Stramonium is a syncope of the Greek name for the Mad-apple (a kind of Nightshade), 
from a supposed resemblance between the fruit of the two plants.
