use tlie young shoots, but allow some of the stems to grow, and as soon 



as the bed outside begins to afford a supply in spring, harden off the 



pot-plants, and set them out behind a north wall during summer. Early 



in autumn they should be cut down, and the pots top-dressed, when 



they may be again introduced into heat as early as needful to keep up 



a supply, and another lot should be lifted in winter to succeed these 



the following year, while the older plants may be planted out. If 



taken care of, the same pot-plants will do for two or three years.

PASSIFLORA QUADRAWGULARIS. 



We are interested in Mr Simpson's article on the above-named plant 

 (p. 71 of the ^Gardener'). Having grown it for the last ten years, 

 and failed to produce fruit to any extent, we may simply state that 

 our plant is grown in a span-roofed cucumber-house, the roots having 

 a space to themselves, and the benefit of a part of the hot-water tank 

 at the north end of the house. The shoots are trained along under 

 the ridge of the roof, and bloom abundantly. The flowers impart to 

 the atmosphere a pleasing odour, and soon drop off. 



The P. edulis fruits freely with us, but the pollen taken from it 

 exerted no influence on more than a dozen other varieties with which 

 we experimented. On P. quadrangularis we once had two fruits 

 effected by pollen from Tacsonia mollissima, and last year one fruit 

 from its own pollen. 



What we are anxious to know, and perhaps Mr Simpson will kindly 

 state, is. What number of glands are on the footstalk of a full-developed 

 leaf of P. quadrangularis to which he refers ? We believe they are 

 characteristic. Are we right in supposing that all the flowers on his 

 plants were impregnated 1 



We may further state, that when in the forcing department at 

 Taymouth Castle eighteen years ago, the back-wall of two fruiting 

 Pine - stoves was covered A\dth two plants of P. quadrangularis 

 inarched on the P. edulis. They produced hundreds of fruits in a season, 

 which were highly esteemed both for dessert and culinary purposes. 

 The plants received no special treatment. Their roots were under a 

 part of the back pathway, consequently they had no bottom-heat ; and 

 being soft-rooted gross feeders, they were occasionally supplied with 

 liquid manure when watering the Pines, but the flowers were impreg- 

 nated with their own pollen. 



The two cases coming under my own observation being so different
