DAUBENYA (named after Dr. Charles Daubeny, a 

 former Professor of Botany, at Oxford). OBD. Liliareae. 

 A genus of pretty and curious little greenhouse bulbs, 

 producing their flowers in very shortly-stalked, densely- 

 flowered umbels, larger than a crown piece. There are 

 three species, natives of the Cape of Good Hope ; at 

 present, they probably do not exist in British gardens. 

 They thrive in a soil composed of sandy loam and peat 

 Increased by offsets. Danbenyas should be quite dry 

 while at rest. 



D. anrea (golden), fl. yellow; perianth tuberose, with a two- 

 lipped limb. June. L oblong, seated dose to the earth. A. Sin. 

 1832. (B. B.1813.) 



D. ftilva (tawny). JL dull reddish-yellow. June. *. 6in- 1836. 

 (B. B. 1839, 53.) 



DAUCTJS (Dauio*, of Dioscorides, is said to be from 

 daio, to make hot ; from its supposed effect in medicine). 

 Carrot. OBD. Umbellifens. For culture, tee Carrot. 

 D. Carota. Carrot jL, umbels white, peduncled; central 

 purplish; bracts of involucre usually piimatifid; bracteoles 

 lanceolate. Summer, i. pinnately decompound ; segments i 

 rather hairy. A. 1ft to 2ft Europe (Britain), North A 

 North and West Asia, to India. Biennial 

 There are about a score other species, but none are worth men- 

 tion, either as ornamental or useful plants. 



D AVAIiIiIA (named after . DavaJl, a Swiss botanist). 

 Including Acrophonu, Humata, Leucosteyia, Loxotcaphe, 

 Microlepia, Odontoloma, Prosaptia, Saecoloma, Scyphularia, 

 and Stenoloma. OBD. FHiees. A large genus of green- 

 house ferns, upwards of a hundred being described in 

 " Synopsis Filicum." Rhizomes creeping, scaly. Involucre 

 terminal on the veins, various in shape, united or free at the 

 sides ; the apex always free. Capsnles stalked. Sori intra- 

 or sub-marginal, globose or elongated either laterally or 

 vertically. For general culture, see Ferns.
