Diplocyatha 



( 302 ) 



Dipteryx 



exhibition plants, while in the former way few 

 plants show to better advantage. In addition to a 

 large number of species a quantity of garden 

 varieties are cultivated. 



Propagation. Cuttings of young shoots root 

 readily in spring if placed in sandy peat in a warm 

 propagating case. 



Soil. Fibrous peat two parts, fibrous loam one 

 part, with a good amount of coarse sand and 

 broken charcoal. 



Other Cultural Points. Beds or pots should 

 always be supplied with a good quantity of drainage, 

 as anything like stagnant moisture is very harmful. 

 Repotting should be done in early spring as growth 

 commences. After potting or planting, a day tem- 

 perature of from 65" to 70" must be kept, dropping 

 5 at night. On all favourable occasions the 

 syringe should be freely used. When well estab- 

 lished plenty of water must be given throughout 

 the summer, with frequent doses of liquid manure. 

 Flowers are borne from May to August, and by 

 starting later in spring a succession may be kept 

 up until October. After the flowers are over the 

 house may be kept a little cooler and the plants 

 on the dry side to ensure a good rest. In mid- 

 winter all side branches must be spurred in to 

 within an eye or two of the old wood. "When 

 trained on trellises care must be taken to tie young 

 shoots in before they become entangled, as they 

 are very easily broken. Red spider is the most 

 troublesome insect pest, and this may be kept down 

 by a free use of the syringe.

DIPLOCYATHA. 



Succulent, Stapelia-like, greenhouse plants (ord. 

 Asclepiadeas) with a dwarf, much - branched 

 habit and small, curious, fleshy flowers, from 

 South Africa. They are propagated by cuttings, 

 and grow in fibrous loam and sand in almost equal 

 proportions. Throughout the winter they must be 

 kept fairly dry. 



Only Species : 



ciliata, (J", sum., grn. (stjn. Stapelia ciliata). 



DIPLOL/ENA. 



Evergreen shrubs (ord. Rutacese), from Australia, 

 with a bushy habit; They thrive in a cool

 Diplopappns (see Aster). 



greenhouse, may be propagated by cuttings of half- 

 ripe shoots in sandy peat, and should be potted 

 firmly in sandy peat. 



Principal Species : 



Dampieri, 4', Ap., wh. grandiflora, 4' to ;V, My., 



wh. 



DIPLOPELTIS. 



Greenhouse evergreen sub-shrubs (ord. Sapin- 

 daceai), with deeply toothed leaves. They are 

 propagated by cuttings of young shoots in sandy 

 soil in a propagating case, and may be grown in 

 fibrous loam and sand. 



Principal Species : 



Huegelii, 1' to 3', Jy., ro., wh. 



DIPLOTHEMIUM. 



Stove Palms (ord. Palmse), with thick rootstocks, 

 very short stems, elegant leaves, and minute 

 yellowish flowers in long dense spikes. They are 

 natives of Brazil and thrive in fibrous loam. 



Principal Species : 

 caudesccus, 10', Ivs. 4' to maritimum, 8', Ivs. 2' to 



5'. 



DIPODIUM. 



Small epiphytal Orchids (ord. Orchidacete), with 

 tiny pseudo-bulbs. Each bulb produces one leaf 

 6" to 8" long. The spikes are G" or 8" long, bear- 

 ing six or eight flowers. One species only is 

 grown ; it may be grown in a stove in pots or 

 baskets in peat, charcoal, and sphagnum. 



Principal Species : 



paludosum, (>" to 8", Oct., grn., wh., pur. lines. 



DIPOSIS. 



Interesting botanical plants from Chili (ord. 

 Urnbellit'erfe), requiring the protection of a cold 

 frame in winter. The flowers are small, green or 

 white, and borne in threes, two males and a female 

 together. Any ordinary garden soil suits. 



Only Species : 



Bulbocastanum, 1', sum'., wh. 



DIPSACUS. (TEASEL.) 



Biennial herbaceous plants (ord. Dipsacesc), with 

 hairy or prickly stems, opposite, deeply toothed 

 leaves, and terminal heads of white, lilac, or 

 purple flowers. The species are principally 

 European and Himalayan. They grow readily 

 from seeds, and thrive in almost any kind of soil. 

 A few only are worthy of cultivation.

DIPTERYX. 



Evergreen trees (ord. Leguminosrc). Odorata 

 produces the Tonga or Tonquin Bean, which is 

 much used in perfumery. They may be increased 

 by means of seeds or cuttings, and succeed in 

 fibrous, well-drained loam in a stove temperature.

 of it.
