develop their true characters. The flowers are very beauti- 

 ful in some species ; in all, they are of singular form and 

 extremely interesting. 



Propagation is readily effected from cuttings of young 

 shoots, about Gin. long, taken in spring with a heel, and 

 inserted singly in small pots of sandy soiL They should 

 be placed in a close propagating frame, or under a bell 

 glass, where they will root in due course pretty freely. 

 Once rooted, and gradually inured to the open house, 

 the plants grow rapidly, and when repotting rather large 

 shifts may be safely allowed. They may eventually be 

 permanently planted out, and the growth trained over the 

 roof or rafters, or cultivated for a similar purpose in 

 large pots or tubs. Passifloras usually grow freely, 

 and are not over-fastidious regarding soil, provided 

 there is good drainage, and plenty of water is 

 given throughout the growing season. If planted in 

 borders, the roots should be partially restricted, and 

 a depth of soil not exceeding a foot will be sufficient. 



Passiflora continued. 



P. Actinia (Sea-anemone-like). fl., petals nearly white, oblong, 

 rather longer than the calyx ; calyx with a short tube, and a limb 

 of five greenish, oblong lobes; crown of numerous spreading, 

 worm-like filaments, deeply banded with red, blue, and white, 

 inclosing three circles of very minute processes ; peduncles axil- 

 lary, single-flowered. November and February. L about Sin. 

 long, ovate, obtuse, emarginate, the petioles scarcely half as 

 long. Organ Mountains, 1842. (B. M. W09.) 



P. adiantifolia (Adiantum-leaved). A form of P. Banksii. 



P. alata (winged-stemmed).* fl. very sweet-scented ; upper side of 

 calyx and petals deep crimson; rays variegated with purple, 

 white, and crimson; pedicels terete; bracts slightly toothed. 

 April to August. L glabrous, somewhat cordate, ovate, acute; 

 petioles bearing four glands ; stipules lanceolately-falcate, some- 

 what serrated. Branches tetragonally winged. Peru, 1772. 

 (B. M. 66 ; L. B. C. 246.) P. Biumapartea is probably a hybrid 

 between this species and P. quadrangularis. 



P. a. brasiliana (Brazilian). Jl. solitary, axillary ; sepals ob- 

 long, very convex, coloured at the edges, each bearing below the 

 end a little bristle ; petals longer, but similar, within deep 

 scarlet, outwardly deep violet, with a white streak along the 

 middle ; crown about as long as the petals, composed of several 

 rows of tapering processes, which are collected into a cylinder, 

 and are white, with crimson bands on the lower half, deep rich

This should be composed of turfy loam with a small 

 portion of peat and some sharp sand intermixed. Very 

 rich soils are apt to cause an over-luxuriant growth 

 at the expense of the floriferous habit which the plants 

 usually assume. Attention should be devoted to 

 training the shoots and preventing overcrowding by 

 cutting the weakest away, allowing the terminal points 

 of others to hang gracefully. When flowering is over, 

 the main growth may be regulated, thinned, if necessary, 

 and cut in. Both stove and greenhouse species thrive 

 under very similar treatment, except that the latter do 

 not require so much heat as the former, and do not 

 generally grow quite so rapidly. P. caerulea succeeds in 

 favourable localities outside. If trained to a south 

 wall, it grows rapidly, and soon covers a large surface. 

 The numerous orange-coloured fruits that ripen towards 

 autumn are as ornamental as the flowers which precede 

 them. 



Except where indicated otherwise, the undermentioned 

 species are climbers, and require stove treatment. 



violet on the upper half. September. 1. about 6in. long, oblong, 

 abruptly pointed; petiole over liin. long, with two yellow, 

 conical glands at the upper end ; stipules narrow. 1831. SYN. 

 P. phaenicea (B. R. 1603). 



P. alato-caernlea (winged-blue). fl., petals white inside ; calyx 

 lobes rose-coloured on the outside ; crown tnple ; outer nlamen- 

 tous appendages variegated with black, blue, and white ; pedicels 

 terete, much longer than the petioles. June to October. 

 I glabrous, cordate, three-lobed ; lobes quite entire, ovate-lanceo- 

 late; petioles bearing two to four glands. 1823. A garden 

 hybrid between P. alata and P. casruUa. (B. R. 848.) 



P. alba (white).* fl. white ; superior peduncles longer than the 

 leaves. May. I glabrous, glaucescent beneath, somewhat cor- 

 date at base, five-nerved, trilobed ; lobes oval, somewhat glandu- 

 larly serrated at base ; petioles biglanclular in the middle. Brazil, 

 1830. SYN. P. atomar&. (G. C. n. s. xix., p. 693; R. H. 1883, 

 Fig. 39.) 



P. alblda (whitish). A synonym of P. mucronata. 



P. albo-nlgra (white and black). JL, petals white ; corona black- 

 ish-purple below, white above. Summer. I. palmately five-lobed. 

 This is said to be a cross between P. alata and P. Jiaddvana. 

 (R. G. 1852, 8.) 



P. amabllis (lovely).* fl., sepals and petals red within, con- 

 formed ; filaments of the corona almost quadnseriate, white, 

 shorter than the perianth ; peduncles solitary, - 1
