A. nerii, Oleander Scale, is found in 

 our stoves and greenhouses, chiefly on 

 the Oleanders, Palmse, Aloes, and Acacias. 



A. roses, Kose Scale ; A. cchinocacti, 

 Cactus Scale ; A. lauri Sweet-Bay Scale ; 

 infest chiefly the plants by the names of 

 which they are distinguished.

Seeds, divisions, and cuttings, the first in the 

 open border. They are of little ornamental in-

COELO'GYNE. (From hollos, hollow, and 



yne, female ; in reference to the female 



Tgan, or pistil. Nat. ord., Orchids [Or- 



chidacero]. Linn., -20-Gynandria l-Mo- 



nandria.) 



To cultivate this genus successfully, divide ifc 

 nto two sections: The first, C. barba'ta, cris- 

 ta'ta, Cumi'ngii, ela'ta, fttligino'sa, ocella'ta, 

 spccio'sa, and some other new species from Bor- 

 neo not yet bloomed in this country. The second 

 section, C. Gardneria'na, macula'tcifpr&cox, anct 

 Wallichia'na. 



The compost for the first section should be 

 chopped sphagnum, turfy peat, using only the 

 fibrous part, and small potsherds. The season 

 For potting is when they begin to grow, about 

 February. Some of the species have long rhi- 

 zomas (creeping stems), and would soon run over 

 the edges of the pot. To keep them at home, 

 place an upright block of wood in the centre of 

 the pot ; clothe it with moss, and, as the plant 

 advances in growth, train to it, and fasten it with, 

 fine copper wire. When growing, they require a 

 liberal amount of water ; but the water must not 

 lodge in the hearts of the young leaves. In very 

 hot weather syringe the plants in the morning, 

 and give air, to dry up the extra moisture. Shade 

 from bright sunshine, removing it off by four or 

 five o'clock. The annual growths should be fi- 

 nished early in the autumn, and then the heat 

 and moisture should be reduced; and, when 

 winter approaches, cease watering altogether. 



For the second section the soil should be a 

 compost of sandy peat, fibrous loam, and half- 

 decayed leaves, with a small portion of river-sand. 

 Drain moderately well, and place four or five 

 bulbs in a 6-inch pot, excepting C. Gardneria'na, 

 which is a strong grower, and requires a larger 

 pot, and fewer pseudo-bulbs in it. Pot as soon 

 as the bloom is over, because, as soon as the 

 flowers decay, the young leaves begin immedi- 

 ately to push forth from the same sheath, and 

 will soon begin to put out new roots. Before that 

 takes place the plants should be potted. THIS 



R.ULK APPLIES TO ALL ORCHIDS. 



Place this section of Coelo'gyne on a shelf near 

 the glass, in a cool stove. Whilst growing, freely 

 water moderately, till the leaves are considerably 

 grown, and then abundantly. In potting, place 

 the bulbs just on the surface of the soil. 



Resting-period Treatment. As soon as the 

 pseudo-bulbs are fully formed cease watering, and 

 allow the leaves to turn yellow and die ; remove 

 them, and continue the plants in the same situ- 

 ation, keeping them dry and cool. Pay attention 

 to them occasionally, to see that the bulbs con- 

 tinue plump and fresh. Should they appear to 

 shrivel, give a little water, which will cause them 

 to swell again ; but be careful not to overdo it, or 

 you may induce them to start prematurely.
