THE FLORAL WORLD AND GARDEN GLIDE.

It may be planted out in a conservatory 

 border or in an orangery, and •would pro- 

 bably do better under such management 

 than in a pot, for none of tins tribe are 

 well adapted for pot culture, owing to the 

 fascicled nature of their roots. The season 

 of blooming is May and June. Price 5*. 



TOEENIA ASIATICA, VAE. PTJLCHEEEIMA. 



The Torenias are members of the im- 

 portant natural order of Figworts, or 



treatment. The best mixture for them is 

 peat and rotted turves, equal parts, old cow- 

 dung and gritty sand, one half-part each. 

 The species most prized are Asiatica, 

 purple ; concolor, purple ; hirsuta, white ; 

 and scabra, pale blue. The variety of T. 

 A. pulcherrima is of a rich slaty purple, 

 with deep blotches on the side petals, and 

 an almost black throat. The lip is pure 

 white, with purple edge, and the orange- 

 coloured stamens contrast admirably 



Torenia Asiatica, var. pulcherrima. 



Scrophulariacese, and are among the most 

 useful and easily managed of stove ever- 

 greens. There is no difficulty either in 

 propagating or flowering them, as the 

 small side shoots strike without a bell- 

 glass if in a moist air, and the blooms 

 come plentifully if the plants have liberal 



against the purple of the back petal. 

 Much as the species is prized, this variety 

 very far excels it in the size and form of 

 the flowers and the splendour of their 

 colouring. It was raised from seed 

 received from India by Messrs. Lee, of 

 Hammersmith. 



CANVAS AS A REPELLENT OF PRO ST. 



Me. Standish's communication about 

 his tiffany-houses is very interesting. I 

 can well understand that canvas has 

 some peculiar and little understood power 

 of keeping off frost, because old Aber- 



cromby tells us that fruit, that is, apples, 

 have been perfectly preserved in a place 

 much exposed to frost by being covered 

 with a linen cloth, and also that woollen 

 has not this effect. A. B.
