MISCELLANY OF NOTES AND CORRt Sl'ONDENCE. 215 



extent, some of the species of Maminillaria by cutting off the protuberances on 

 Mammillaria, which, after beimr dried on sand, produced perfect plants under a 

 bell-glass with bottom-heat. — iV". S. Hudson (Gardeners' Chronicle). 



Blue and White Flowered Pyramidal Campanulas. — This plant, when 

 grown to a degree of vigour it is capable of, by a rich soil, and plenty of pot room, 

 with one or more shiftings into larger as required, I find to grow nine feet high, 

 with numerous subordinate spikes, and during some months at the end of sum- 

 mer to make one of the most showy plants in cultivation. As the pots may be 

 purchased at five shillings per dozen, I am induced to send this small notice of 

 the plant, that the readers of the Cabinet may be enabled to provide and culti- 

 vate this truly sweet and splendid flowering plant. When grown in pots, it forms 

 one of the most ornamental plants for a greenhouse-room, or to be placed in a 

 vase on the lawn, or in a flower-garden. Or if grown in the open border in a 

 deep and rich soil, it merits a place in all. I have found that by placing one of 

 the blue flowered kinds in a shady place in the greenhouse or room, the flowers 

 become paler and ate of a most beautiful French lilac colour, most strikingly 

 handsome.

Labels made of Glass. — The best kind of label for marking plants is a pro- 

 blem that, I think, has not yet been solved. The marks on wood and iron soon 

 become indistinct. The removal of the duty on glass drew my attention to the 

 subject. No. 1 is a tube of glass, half-inch internal diameter, about two inches 

 long from shoulder to bottom ; the name of the plant is printed or written on a 

 piece of paper, about one inch and a half square, folded cyliudrically, and intro- 

 duced into the tube. The tube is then corked and sealed with resin, sealing-wax, 

 asphalte, thick paint, or other cement. A piece of very slender copper-wire is 

 twisted round the neck of the tube by which it may he attached to a wooden or 

 metallic support, or to the branch of a shrub or tree. The ahove will probably 

 be most generally used, as the label can be introduced or changed at pleasure. 

 But No. 2, in which the tube is closed hermetically, will, on account of its neat- 

 ness and perfection, be preferred by many. When used, the names of the plants 

 mu-t be sent to the glass-blower to be inserted before sealing the tube hermeti- 

 cally. — Jos. C. Gamble ( Gardeners' Chronicle). 



On Achimenes argykostigma. — The best way of cultivating this plant is to 

 grow it in masses planted in large pans or pots, as it then produces a multitude 

 of spikes of its pretty delicate looking flowers, which present a graceful, and I 

 think elegant, appearance, that goes far to compensate for any deficiency of those 

 brilliant colours which distinguish its brethren. C. 



Floral Operations for August. 



Pelargoniums — Plants that have done blooming should soon be cut down, 

 this will induce them to push fresh shouts immediately. When the shoots have 

 pushed two inches long, the old plants should be repotted, shaking off' the old 

 Boil and replacing with new. This attention to have a supply of strong young 

 shoots before winter, furnishes the vigorous blooming wood for the ensuing 

 spring, and the plants are kept dwarf and hushy. When the young shoots push 

 after hemg headed down, there are generally many more than necessary to be 

 retained. They should he thinned when an inch long, and the tops now cut off 

 may be insetted in sandy loam, and struck if required. 



(ihei'.n house. — The young wood of many kinds of greenhouse plants being 

 sufficiently hardened, if cuttings be immediately put in they will loot well before 

 autumn. 



Camellias may be shifted at this period. I consider it an excellent plan to
