renewed. This will impart to them the 

 requisite vigour to grow and bloom for a 

 few more years, when the ojjeration may 

 be repeated or their places supplied by 

 young plants, which, from their freedom 

 to strike and grow, there is little difficulty 

 in getting up to a large size in a short 

 time. 



The most suitable kinds for general culti- 

 vation are : — 



P. alata. A handsome free-growing 

 sort, with red and purple flowers. West 

 Indies. 



P. amabilis. A free-growing, handsome 

 variety, from South America, bearing scarlet 

 and white flowers. 



P. Biionapartea. A strong -growing, 

 large-leaved kind, with blue, white, and 

 red flowers. 



P. cardinalis. A very handsome kind, 

 with bright effective flowers produced 

 freely. Suitable for a large house. 



P. Decaisneana. A fine free -growing 

 kind. 



P. kermesina. This is a handsome kind 

 that branches fi'eely, and produces its crim- 

 son flowers in abundance. 



P. Loudonii. A moderate grower, bear- 

 ing handsome purple flowers, produced

P. princeps. A handsome, moderately 

 vigorous kind with scarlet flowers. Brazil. 



P. quadrangularis. A strong-growing 

 kind with broad massive green leaves, and 

 blue, green, and red flowers. Jamaica. 



P. qiiad.rangularis cmcubcefolia. A ^•arie- 

 gated-leaved foim of the above with hand- 

 somely-marked foliage. 



Insects. — Passifloras are not more sub- 

 ject to insects than the generality of heat- 

 requiring plants, but these parasites will 

 live on them, especially mealy bug, which 

 must be sought for at the base of the 

 leaves and in the crevices of the bark on 

 the mature stems and half-ripened shoots ; 

 also, the syringe can be freely employed, 

 and will be a means of keeping them under, 

 still fiirther aided by strong washings with 

 insecticide when the plants are at rest. 

 Remove scale by sponging, and should 

 thrips or red spider make their appearance, 

 a free use of the syringe will be the best 

 remedy. 



PASSIFLORA. 



(Greenhouse.) 



Among these are some of the most 

 beautiful and fi'ee-growing climbers, best 

 adapted for a good-sized house. 



Their propagation and cultivation is 

 similar to that given for the stove species, 

 except that, as a matter of course, they re- 



quire less heat, and their growth is slower, 

 taking a longer time to attain a size suit- 

 able for planting out. 



The undermentioned are desirable kinds : 



P. Campbellii. Red. 



P. cceruleo-racemosa. Purple. A garden 

 variety. 



P. edidis. Blue and white. The fruit 

 of this species, purple in colour, is edible. 

 Brazil. 



P. Imperatrice Eugenie. Violet, white, 

 and lilac. Brazil. 



P. onycliina. Purple. Buenos Ayres. 



P. palmata. Blue, purple, and white. 

 Brazil. 



P. sanguinea. Crimson, violet, and 

 white. Columbia. 



PAULLINIA. 



Evergreen stove plants with elegant 

 foliage, borne on slender shoots. Tliey 

 do not require much room, and on that 

 account are preferable to many of the 

 coarser-growing kinds of fine-leaved sub- 

 jects. 



They are increased by cuttings which 

 require to be potted and grown on in the 

 usual way with plenty of heat in summer, 

 and should be kept proportionately warm 

 in winter. They may be trained on sticks 

 so as to form a loose bush, or look well 

 suspended with the shoots hanging down. 



2^. oceanica. A beautiful species, ^vith 

 small leaves, borne alternately on dark 

 coloured shoots. From the South Sea 

 Islands. 



P. thalictrifolia. A handsome kind, 

 with small, pretty foliage. The slioots 

 have a tliin, wiry apjaearance, and require 

 support. From Brazil. 



Insects. — Most of the insects that affect 

 stove plants are troublesome on the Paul- 

 linias ; constant attention must be given 

 them by syringing and sponging, if at all 

 affected, or the foliage gets so far injured 

 as to spoil their appearance, 



PAVETTA. 



Two species of these handsome plants 

 well deserve a place in the stove, viz., P. 

 borbonica and P. caffra. Of these the first 

 is one of the most beautiful of evei'green 

 variegated stove subjects. It is a hard- 

 wooded species, erect in habit, and incap- 

 able of being made to branch out until it 

 has acquired considerable strength and 

 height. Indeed, it looks best when con- 

 fined to a single stem. The leaves are a 

 foot or more in length, shining, bright 

 green, distinctly marked with Ijlackish 

 green, and the midrib red. It may be
