DILATED. Widened. 



DILATRIS (from dilate, to open wide; referring to 

 the opening of the flower). OBD. Hcemodoracea}. A genus 

 of greenhouse herbaceous plants, containing a couple of 

 species, natives of the Cape of Good Hope. Flowers 

 purple or yellow, corymbose or panicled ; perianth petaloid, 

 externally downy, superior, six-parted, the segments erect, 

 persistent. Leaves radical, equitant, ensiform, rigid, sheath- 

 ing at the base. For culture, see Anigozanthus.

DILL (Aneth-um graveolens). A herb rarely grown in 

 this country. It is used for flavouring soups, sauces, &c., 

 for which purpose the young leaves only are required. It 

 is of very easy culture. Seeds may be sown broadcast, or 

 in drills, about March or April, in any ordinary garden 

 soil ; and, if the flower-stalks are allowed to remain and 

 seed each year, plenty of plants will always be produced. 

 The genus Anethum is now included, by Bentham and 

 Hooker, under Peucedanum. 



DIIiIiENIA (named after John James Dillenius, a 

 former Professor of Botany, at Oxford, author of " Historia 

 Muscornm," and "Hortus Elthamensis.") Including Col- 

 bertia. OBD. Dilleniacece. A genus of less than a score 

 species of very beautiful stove evergreen trees, with large 

 flowers ; they are only suited to places where plenty of 

 room can be afforded. They thrive in a light sandy loam. 

 Cuttings of half -ripened wood root readily, if inserted in 

 sand, under a glass, in bottom heat. Seeds are sometimes 

 imported, and are usually found to grow without much 

 difficulty. 



D. pentagyna (flve-carpelled). Jl. yellow ; petals ovate-oblong, 

 acute ; pedicels one-flowered, clustered along the naked branches 

 of the preceding year. March. I. oblong, villous on the nerves 

 beneath, h. 20ft. India, 1803. SYN. Colbertia coromandelina. 



D. scabrella (roughish). /. yellow, fragrant ; petals orbicular, 

 or obovate ; peduncles in axillary fascicles, 



each furnished with 



I. elliptical, .acute, 1ft. long,

 tures. Assam and Sylhet, 1820. A spreading tree. 



two opposite bracts, glabrous. I. ellipt

D. speclosa (showy), fl. white, with yellow stamens, 9in. in 

 diameter; peduncles one-flowered. I. very ornamental, elliptical- 

 oblong, simply serrated, 6in. to 1ft. long, bright light green. 

 h. 40ft. East India, 1800. One of the handsomest of Indian 

 trees, whether the beautiful foliage is considered, or the size and 

 structure of the flowers. In this country, however, it is a rather 

 spreading bush. (B. M. 5016.) 



DILLENIACE2E. A rather large order of trees, 

 shrubs, or suffruticose herbs, allied to the Magnoliads. 

 Flowers yellow or white, often very showy, hermaphrodite 

 or polygamous, rarely dioecious ; sepals five (rarely three, 

 four, or numerous), persistent, in two rows ; petals five, or 

 fewer, deciduous. Fruit consisting of two or five distinct 

 or united carpels. There are about seventeen genera and 

 200 species, chiefly found in Australia, India, and North 

 America. Some are large timber trees, while others are 

 fruit-producing. Well-known genera are : Candollea, De- 

 lima, Dillenia, and Tetracera.
