DILIVARIA. See Acanthus. 



DILL (AnHhum graveolens, Linn.), an annual or 

 biennial plant of the Umbelliferoe. Native of S. Eu., 

 the seeds of which are used as a seasoning, as seeds of 

 Caraway and Coriander are. It is of tlie easiest culture 

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

 grows 2-3 ft. high : the lvs. 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 Linna?us for J. J. Dillenius, 

 botanist and professor at Oxford). Diltenidcea>. A ge- 

 nus of 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 ranch 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 venation: fls. 

 white or yellow, lateral, solitary or clustered. D. Iiidica 

 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 

 bro;id, 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 raya of the

DIMOBPHOTHfiCA (( leek tuo fotmed receptacle 

 the disk florets of two kinds) Cumpdsita Acharraiug 

 genus of pKnts from the Cape of Ctood Hope which is 

 almost totall> neglected heie 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-peduncled: 

 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 Gfazania, 

 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 coolhouses and flowered in spring, 

 or else transplanted to the open, where they flower freely 

 during summer. The shrubby kind, D. Feklonis, 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 Sender, Flora Capensis 3:417 (1864-65). 

 Sometimes called Cape Marigolds. 



Annua, Less. (CaUndula pluvidlis, Linn.). This is 

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

 sold in America at present. Erect or diffuse, simple or 

 branched, rough with jointed and gland-tipped hairs

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