BE. Fls. wliite to purple, seldom yellowish. 



purpiirea, Linn. {B. tomentbsa, Link. & 

 Hoffmgg.). Common Foxglove. The species most 

 commonly cultivated. Mostly biennial, but some- 

 times perennial. Height 2-3 ft. : Ivs. rugose, some-

 longer racemes, larger fls., which open wider, 

 nearly always strongly spotted, though a sub- 

 variety, gloxinicefldra dlha, is offered. V. alba and 

 punctata of the seed trade are presumably white 

 and spotted varieties. X>. alba, Sahr&iik ='D. pur-

 plish, pale inside, spotted at the mouth; lower lobe of corolla 

 short. Eu. F. A.Wauqh. 



DILIVAKIA. See Acanthus. 



DILL {Anethum graviolens, Linn.), an annual or 

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

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



DILLflNIA (named by Linnaeus for J. J. Dillenius, 

 botanist and professor at Oxford). JJillenidcece. 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 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 venation : fls. 

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

 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. specibsa, 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). -^ lyj

DIMOEPHOTHfiCA (Greek, two-formed receptacle; 

 the disk florets of two kinds). Compdsitce. A charming 

 genus of plants from 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, 

 tooth ed, 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 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 coolhouses and flowered in spring, 

 or else transplanted to the open, where they flower freely 

 during summer. The shrubby kind, D. Fcklonis, 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. 



innua. Less. {OaUndula pluridlis, 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 

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

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