DILIVAEIA. See Aeanthns. 



DILL \Anethnm graveolens, Linn.), an annual or 

 biennial plant of the Umbellifer(r. Native of S. Eu., 

 the seeds of which are used as a seasoning, as seed.? of 

 Caraway and Coriander are. It is of the easiest culture 

 from seeds. It should have a warm position. The plant 

 grows 2-3 ft. high: the Ivs. are cut into thread-like di- 

 visions: the stem is very smooth; the fls. are small and 

 yellowish, the little petals falling early. It is a hardy 

 plant. The foliage is sometimes used in flavoring, and 

 medicinal preparations are made from the plant. The 

 seeds are very flat and bitter-flavored. 



DILL£NIA (named by Linnaeus for J. J. Dillenius, 

 botanist and professor at Oxford). Dilleniiicea'. A ge- 

 nus o£ handsome East Indian trees, thought by some to 

 be as showy as a magnolia. One species is cult, in S. 

 Fla. and S. Calif. , but it takes too much room and 

 flowers too rarely for northern conservatories. It has 

 gorgeous white fls. fully 9 in. across. Tall tropical trees 

 from Asia, Indian Archipelago and Australia. Lvs. 

 large, with pronounced pinnate, parallel ven.ation : fls. 

 white or yellow, lateral, solitary or clustered. V. Jndica 

 is said to be the showiest of the whole order, being at- 

 tractive in foliage, flower and fruit. Dillenias may be 

 grown in light, sandy loam. Prop, readily by seeds, but 

 with difficulty from cuttings. 



Indica, Linn. {D. speciosa, Thunb.). Trunk stout, 

 not high: branches numerous, spreading, then ascend- 

 ing: lvs. confined to the ends of branches, on short, 

 broad, channelled sheathing petioles, the blade 6-12 in. 

 long, oblong or oblong-lanceolate, acuminate, narrowed 

 at the base, strongly serrate: sepals .5, thick, fleshy, en- 

 larging and inclosing the fr. ; petals obovate, white; sta- 

 mens very numerous, forming a large yellow globe 

 crowned by the white, slender, spreading rays of the 



stigma: fr. edible, acid, the size of an apple, many celled 

 and many ovuled. Trop. Asia. B.M. 5016 (B.M. 449= 

 Hibbertia volubilis). w. M. 



DIMORPHANTHUS. Included in Aralia.

DIMOEPHOTHfiCA (Greek, two-formed receptacle; 

 the .ii.-k 111. ri'ts (.f two kinds). Compiisita. Acharming 

 genus of i>I;uiis fiuni the Cape of Good Hope which is 

 almost totally neglected here, largely because the cli- 

 matic conditions of that wonderful region are not gen- 

 erally understood. This genus contains about 20 spe- 

 cies, some of which rival the Paris Daisy and others vie 

 with Cinerarias. Annual or perennial herbs, or even 

 somewhat shrubby: lvs alternate or radical, entire, 

 toothed, or incised, often narrow: heads long-peduncles' 

 rays yellow, orange, purple or white: disk fls. same 

 colors except white. The genus is closely allied to Ca- 

 lendula, but has straight instead of incurved seeds. The 

 fls. are usually said to close up, like those of Gazania, 

 unless they have sunlight. Their backs have as great 

 a variety of coloring as their faces. The fls. are often 3 

 in. across, and their long, slender rays (20 or more) give 

 a distinct and charming effect. A dozen kinds are grown 

 abroad, representing a wide range of colors and foliage. 

 They are wintered in coolbouses and flowere<l in spring, 

 or else transplanted to the open, where they flower freely 

 during summer. The shrubby kind, D. Ecklonis, has 

 been grown at Kew as a summer bedding plant, flower- 

 ing from July to frost, and was a surprising success as 

 a coolhouse plant, making a much branched plant 3 ft. 

 high, and flowering freely all spring. Monograph by 

 Harvey and Sonder, Flora Capensis 3:417 (1864—65). 

 Sometimes called Cape Marigolds. 



Annua, Less. {CaUndida pluvidlis, Linn.). This is 

 the only white-fld. annual kind and the only species 

 sold in America at present. Erect or difl'use, simple or 

 branched, rough with jointed and gland-tipped hairs 

 (seen with a small lens): lvs. narrowly oblong or oho- 

 vate-oblong, tapering to the base, with a few distant
