DIOSMA. 



Greenhouse evergreen shrubs (iird. Rutacese) 

 from South Africa. They are usually more or less 

 lloath-like in habit. Cuttings of young shoots 

 strike in April, and half-ripe shoots in August, in 

 windy peat, in a close propagating case. Fibrous 

 pent, to which has been added a good quantity of 

 sand, is suitable. The pots must always be well 

 drained, and the smaller they are the better, pro- 

 viding the plants are not starved. Firm potting is 

 essential. Frequent stopping is necessary, especially 

 when young, to ensure a bushy habit. As little 

 fire heat as possible must be given, enough to 

 exclude frost only being wanted. The plants may 

 be plunged out of doors during summer.

DIOSPYROS. 



Description. Evergreen or deciduous trees, widely 

 distributed throughout Asia, also found in tropical 

 Africa, North America, etc. (ord. EbenaceaV). The 

 leaves are usually more or less oval in shape, some- 

 times large and Magnolia-like. The flowers are 

 not showy, and of no decorative use. Several 

 species are very useful on account of their large, 

 Apple-like, orange-coloured, edible fruit, and others 

 on account of the hardness and durability of their 

 wood. The best example of the former is the 

 Date Plum, Kaki, and of the latter the Ceylon 

 Ebony, Ebenum. The majority require indoor 

 culture, but a few species are hardy. Kaki may 

 be grown out of doors on a south wall in favoured 

 localities. 



Propagation. Cuttings of soft young shoots may 

 be rooted in a warm, close case in spring, or seeds 

 sown in a stove temperature at any time. The 

 best varieties of Kaki are grafted on stocks of the 

 typical plant in a similar way to the Apple. 



Soil. Good fibrous loam and sand, or, if the 

 loam is very heavy, a little fibrous peat may be 

 added. 



Other Cultural Points. The fruiting plants 

 should be treated in a similar manner to Apple 

 trees in the manner of pruning ; others being pruned 

 to keep them in shape. When fruit is set, plenty of 

 water must be given. Deciduous species are better 

 kept on the dry side in winter.

DIOTIS (at/n. OTAXTHUS). 



A hardy herbaceous perennial (ord. Compositae), 

 with creeping rootstock, whitish, silky-looking 

 leaves and stems, and heads of yellow flowers. It is 

 found in South Europe, the Canaries, and occasion- 

 ally in the southern parts of liritain. It is 

 increased by division, grows readily in almost any 

 soil, and makes a useful plant for massing in front 

 of taller herbaceous plants.

DIPCADI. 



Hardy or greenhouse bulbs (ord. Liliacese), from 

 South Europe, Africa, etc. A few species only 

 are cultivated ; they usually have a few fairly long, 

 bright green leaves, and loose, few-flowered racemes 

 of green or greenish yellow flowers. They are 

 increased by division of the bulbs, and require well- 

 drained, sandy loam. Little or no water must be 

 given during the resting period.

DIPHYLLEIA. 



A pretty, hardy, herbaceous plant (ord. Berber- 

 ideas), which has only two leaves and heads of 

 white flowers, followed by blue berries. It likes a 

 moist, peaty soil and a rather shady place. In- 

 creased by division in spring or by sowing the 

 berries when ripe. 



Principal Species : 

 cvmosa, 1', lly., wh. I'mbrella Leaf. 



DIPHYSA. 



Evergreen trees or shrubs (ord. Leguminosae), 

 with ornamental leaves, yellow, Pea-shaped flowers, 

 and bladder - like fruits. Natives of tropical 

 America. Increased by cuttings of young shoots 

 in spring, and grown in a stove in a mixture ol 

 fibrous peat and loam. 



Principal Species : 

 carthagenensis, 10' to 12', sum., yel. 



DIPLACUS. 



Small greenhouse shrubs (iird. Scrophularinese) 

 of easy culture, and valued for their large orange 

 and coppery red or scarlet flowers, now referred 

 to Mimulus. Glutinosus is Mimulus glutinosus. 

 Puniceus is Mimulus glutinosus var. coccineus. 

 The typical form has orange flowers. Propagation 

 is effected by cuttings of half-ripened wood in 

 sand under a bell-glass. Soil, two-thirds fibrous 

 loam and one-third leaf mould and sand. 



DIPLADENIA. 



Description. Ornamental evergreen twining 

 plants (ord. Apocynacea:) requiring the tempera- 

 ture of a stove. They are from South America, 

 and are distinguished by opposite, entire leaves 

 and clusters of very showy, white, purple, pink, 

 rose, or crimson, tubular, wide-mouthed flowers. 

 They may either be grown in a border and trained 

 to the roof of a house, or grown in puts, trained 

 on stakes or on a wire trellis or balloon. When 

 cultivated in the latter manner they make excellent
