steeped in water for a quarter of an liour previous to potting. When 

 the flower-buds are in clusters tliin them, so as to leave no more than 

 are likely to be perfected. If too many remain they injure the plant, 

 and eventually drop off in spring. 



Calceolarias that have done blooming should have the stems cut 

 down, then place the plants in a cool frame, and shade from hot sun. 

 In about ten days re-pot them. (See Article in July Number, 1846.) 



The very hot and drj' weather will be favourable for the Red Spider 

 upon many of the new Holland plants, as Chorozemas, &c., also Thun- 

 bergias, &c. : to prevent them, occasionally place the plant so as it 

 can be forcibly syringed at the under side of the leaves, and if strong 

 soapsuds are used, the better ; as such a composition leaves a glutinous 

 matter. If a plant be infested, syringe it, and whilst wet turn it over 

 and dust it under the leaves with common sulphur. A good syringing 

 of the plants three times a week is highly beneficial to the entire stock, 

 avoiding the flowers, and performing it at the evening. "Well water 

 the ground where the plants stand, that is, between the pots. 



Leschenaultias, Pimeleas, Baronias, Polygalas, and similar plants, 

 done blooming, should now be cut, in order to have the plants brought 

 into a proper bushy form, after which place them in a situation where 

 they can be shaded from hot sun, to cause them to push fresh shoots. 

 If young stock be required of any kinds of greenhouse plants, and 

 there be young wood sufficiently ripened, cuttings should immediately 

 be inserted, as the season is getting to a close for success this year. 

 Ee-pot specimen plants of the above-named kinds as early as possible 

 after they begin to push : this prepares for next season's success. 



Cinerarias required for blooming in autumn and the early part of 

 winter should be immediately potted and duly forwarded. 



ON CALLA ^THIOPICA. 



BY CLEBICUS. 



Noticing that a correspondent has lately inquired how the Calla 

 ^thiopica is to be treated, in order to bloom it satisfactorily : I have 

 two plants in my greenhouse which meet ray expectations, by treating 

 it as follows : — I grow it in a good rich turfy loam, a good drainage, 

 and in the growing season give it a liberal supply of soft water. The 

 winter season I allow it to rest, and only keep it barely moist ; at the 

 end of February I commence watering gradually, and place the plant 

 Avhere it gets an increase of warmth. As soon as I perceive the slightest 

 move in growth, I take the plant out of the pot, keeping the ball as 

 entire as 1 can, then remove by the hand carefully the exterior part of 

 the soil, avoiding injuring the roots. This being done, I repot it, and 

 as the extremity of the roots will just be pushing, they soon extend in 

 the fresh compost, and by due attention afterwards a vigorous bloom is 

 obtained.
