Datura, Linn. An alteration of the Arabic 

 name, tatorah. Linn. 5, Or. 1, Nat. Or. Sola- 

 vucew. An ornamental genus, but chiefly com- 

 posed of plants possessing very deleterious 

 qualities. The seeds of X>. ceratocaulon will 

 sometimes remain in the ground for several 

 years before they vegetate. The seeds of all 

 the species require to be sown early in spring, 

 on a hotbed, and when of sufficient size they 

 should be transplanted into a warm border, 

 where they will flower better than if kept in 

 pots. In the United States the juice of D. 

 Stramonium is used in doses of from twenty to 

 thirty grains in cases of epilepsy, or of mania 

 without fever. Synonymes: 1, hilmilis; 2,

Daubenya. Dr. Lindley named this genus 

 after Dr. Charles Daubeny, the late professor 

 of botany at Oxford, and well known for his 

 physiological researches. Linn. 6, Or. 1, Nat. 

 Or. Liliacece. This is a very pretty as well 

 as a singular little genus, producing its beau- 

 tiful yellow flowers in an umbel larger than 

 a crown-piece. It will grow well in sandy 

 loam and peat, and may be increased from off- 

 sets. Synonyme : 1 , Massdnia lutea.

 DAUCUS, Toumcfort. From daio, to make hot ; 

 in allusion to its supposed effect in medicine. 

 Linn. 5, Or. 2, Wat. Or. Apiaceoe. Some of 

 the species of this genus are very useful, as B. 

 Carbta, and its varieties which yield the escu- 

 lent root so well known under the name of car- 

 rot. They grow well in any common soil ; the 

 seeds require to be sown towards the end of 

 March, or beginning of April. See Platyspir- 

 mum, and Trachyspermum.

 Davallia, Smith. In honour of Edmund Da- 

 vall, a Swiss botanist. Linn. 24, Or. 1, Nat. 

 Or. Polypodiacece. This is a genus of very 

 beautiful ferns. The rootstock of D. cana- 

 riensis curves over the side of the pot in which 

 it grows, and being covered with close brown 

 hair, it very much resembles a hare's-foot ; 

 hence it is commonly called the hare's foot 

 fern. The species thrive well in a mixture of 

 peat and loam, and may be increased by divi- 

 sions at the roots, or by seeds. Synonyme: 1, 

 Triehtmanes gibberdsa.

Daviesia, Smith. In honour of the Kev. Hugh 

 Davies, F.L.S., a Welsh botanist. Linn. 10, 

 Or. 1, Nat. Or. Pabacece. The species are all 

 very handsome plants when in flower ; they do 

 best in an equal mixture of loam, peat, and 

 sand ; cuttings nearly ripened, of all the 

 species, will root readily in sand, under a glass.
