 peat and loam, with sand to ensure porosity. 

 Propagation is by cuttings of half-ripened wood 

 ini-c'i-tei I in sand beneath a bell-glass over bottom 

 heal. 



DRESSING. 



This term is applied to the trimming up of 

 plants by the removal of dead leaves, flowers, and 

 seed pods, and to the loosening of the surface soil 

 of borders and beds to give them a neat, tidy 

 appearance. It is sometimes applied to the 

 surface dressings on Asparagus beds and in Straw- 

 berry and Kaspberry quarters ; this is top-dressing 

 01 mulching. The term is in vogue amongst ex- 

 hibitors of Chrysanthemums, Hoses, Carnations, 

 and other llowcrs, who, after manipulating the 

 petals or florets, so as tu place them in the shape 

 and position required, with ivory tweezers, speak of 

 t he blooms as " dressed.'" 



DRILL. 



To admit of quick surface cultivation, and also 

 to ensure a certain amount of room to each plant, 

 garden and farm seeds are almost always now 

 sown in drills or shallow trenches. The general 

 method of drawing drills is to stretch a line along 

 the desired site, and, using it as a guide, make the 

 drills, by means of a hoe. shallow or deep to 

 accommodate line' or large seeds. By means of a 

 rake-like instrii nt with adjustable, coulter- 

 shaped teeth, several drills may be drawn at once. 

 The ingenious little American machine known as 

 the Planet Junior Cultivator is used as a hoe, but 

 is also Titled with adjustable coulters for making 

 drills at various depths and widths. 



DRIMIA. 



Interesting little bulbous plants (ord. Liliaceie) 

 allied to the Lachenalias. Although not of strik- 

 ing colours, they are of pleasing appearance. They 

 are grown in the greenhouse in jmts filled with 

 sandy loam and peat or leaf soil. When at res' 

 they must be kept almost dry, and repotted when 

 growth begins to show. Propagated by offsets.

DRIMIOPSIS. 



Greenhouse bulbs (ord. Liliacea;) which bear a 

 considerable resemblance to the Drimins, and 

 require similar cultivation. The two following, 

 although seldom seen, are in cultivation, and are 

 the best of those which have been introduced.

DRIMYS. 



This small genus (rd. Jlagnoliacesc) has some 

 economic value, as Winter! provides the Winter's 

 Bark of commerce, which resembles Cinnamon, 

 and is sometimes used for it. This bark is Mild to 

 be good in cases of scurvy. They are evergreen 

 half-hardy trees, and will thrive out of doors in

DROSERA. (SUNDEW.) 



Interesting and curious insectivorous plants (ord. 

 Droseraceie). Beautiful as are our native species, 

 Anglica, intermedia, and rotundifolia, when ex- 

 amined, they are rivalled by the exotics. Our own 

 are hardy, but, like the exotic species, do well in a 

 greenhouse. Propagation is by seeds, or by division 

 of the crowns. Root cuttings of binata laid on 

 sandy peat, covered with similar soil, and then 

 with a bell-glass, will form plants if kept moist. 

 Soil, peat and live sphagnum, the plants being 

 placed in some of the latter on the top of the pots.

DROSOPHYLLUM. 



The only species of the genus, lusitanicum (i>rd. 

 Droseracere) is a greenhouse plant 1' high, which 

 produces its pretty yellow flowers in late spring. 

 Propagation is by seeds, and the plant grows best 

 in light loam and sand ; it must never be heavily 

 watered. Viscid drops gather upon the leaves, 

 and flies -which alight thereon cannot escape ; 

 their juices are absorbed by the leaves as in other 

 carnivorous plants. 



DRYANDRA. 



This genus (ord. Proteacesc) comprises a con- 

 siderable number of species, few of which have 

 received much attention from horticulturists. All 

 are greenhouse evergreen shrubs that thrive in 

 fibrous peat and loam, with sand and charcoal to 

 ensure porosity ; the drainage must be perfect. 

 Propagation is by cuttings in sand beneath a bell- 

 glass over gentle bottom heat ; they must be 

 transferred from the cutting pots immediately 

 they are rooted. 



Principal Species : 



calophylla, 2', Je., yel. ; floribuuda, 3', Je., yel.

DRYAS. 



Very beautiful dwarf shrubby plants (urd. 

 llosaceae), perfectly hardy in moist, peaty soil, and 

 attractive in the lower portions of the rockery, or
