DEINANTHE BIFIDA, Max. 



Jour. B.H.S. 1903, vol. xxviii. p. 62. 



A rather tall-growing herbaceous perennial with unisexual, herma- 

 phrodite, and sterile flowers on one and the same inflorescence, in 

 general appearance resembling those of the Hydrangea, of which it is a 

 near ally. The leaves large, usually in whorls of four, broadly ovate, 

 serrate margins have often a bifid apex. 



DELPHINIUM CAEDINALE, Hook. 



Bot. Mag. t. 4887. 



A handsome species of Larkspur from California, due to William Lobb. 



The rich scarlet colour of this much-cultivated, well-known plant was, 

 prior to introduction, unknown in the genus, and is still unique. 



In a description in the Botanical Magazine (I.e. supra) Sir Joseph 

 Hooker writes : " Blue or purple or white Larkspurs are familiar to us 

 in our gardens. We have now the pleasure of making known a species of 

 Delphinium equalling if not surpassing any other in the size and symmetry 

 of the plant, and excelling in the brilliancy of colour of the flower, and 

 that as rich a scarlet as can well be looked upon. It is one of the many 

 novelties detected by William Lobb in California, and introduced to our 

 gardens by Messrs. Veitch & Sons of the Exeter and Chelsea nurseries." 



DELPHINIUM DAVIDII, Franch. 



This species, from seed collected on Mount Omei, in the extreme 

 West of China, grows some 2 ft. high, developing flowers of a very rich 

 rose-purple. The foliage is typical of the genus, but the flowers do not 

 compare in size with those of the finer garden forms. 



DICENTEA CHEYSANTHA, Walp. 



Syns. Dielytra chrysantha. 



Fl. des Serres, torn viii. p. 193 ; Bot. Mag. t. 7954. 



First detected by David Douglas, but not introduced, and flowered at 

 Exeter 1852, from seed sent from California by William Lobb. 



Long branching panicles of yellow blooms appear in August and Sep- 

 tember, and, though the plant is hardy and very beautiful, it is short-lived. 

 The leaves large, glaucous-green, pinnately divided ; the ultimate lobes 

 small linear or cuneate, somewhat acute. 



DICENTEA MACEANTHA, Oliv. 



Hooker's Ic. PI. pi. 1937. 



This is an important addition to a favourite garden genus, which includes
