plum or a small apricot. The plant flowers best when planted in the free ground of a conservatory, but it will grow 
in the open air if it is sheltered from severe frost. It should be grown in a light rich soil, and it may be propagated 
by cuttings. When the plant has done flowering, the shoots should be well cut in, as it is found that the shoots 
in spring break better from the old wood than from that of the previous year. The flowers are always produced on 
the shoots of the current year; they have a faint scent, and only last one day. During the winter the plant should 
be kept in perfect rest.

Description, &c. — This is a very showy plant, which was raised in 1823 from seeds of P. alata, a native of the 
West Indies, fertilised by the pollen of P. cmrulea, at the nursery of Mr. William Masters, St. Peter’s Street, 
Canterbury. “ The stem of this hybrid,” says Dr. Lindley, in the Botanical Register, “bears an evident resem- 
blance to that of P. alata, being square ; the membrane of the angles is, however, nearly obsolete, except in 
vigorous young shoots. Its leaves are of much the same texture and colour as those of P. alata, but are three- 
lobed, and very different from those of any other hardy creeper. The flowers are sweet-scented and extremely 
beautiful, the ray being of a rich purple, the petals pink, and the sepals of a delicate white.” The plant is very 
nearly hardy, and may be grown in the open air in a sheltered situation with only a very slight protection during 
frosty weather. 
OTHER SPECIES OF PASSIFLORA. 
P. CAIRULEA RACEMOSA Sal. 
This is another hybrid which, like the last, is very nearly hardy. It was raised from the seed of P. racemosa, 
fertilised by the pollen of P. cmrulea in the year 1820. It is ornamental, but not quite so much so as P. alato- 
carulea. There are several other hybrids which have been raised from either the seed or pollen of P. cmrulea, all 
of which are more or less ornamental 
P. INCARNATA Lin. 
This species, the popular names of which are the common Granadilla and May Apple, was the eaidiest known in 
this country, having been introduced before 1629. It is a native of Virginia in North America, but it will not live 
in this country without the protection of a greenhouse. The flowers are sweeLscented, but not very ornamental. 
The fruit, which is about the size of an apple and of a deep orange when ripe, contains a sweet juicy pulp, which is 
thought very agreeable to eat. There is a variety of this species, the flowers of which are rather ornamental. 
P. LUTEA Lin. 
This is another North American species. It has herbaceous stems, and the flowers are of a pale yellow, but 
they are very small and not at all ornamental. 
P. MIDDLETONIANA Sort. 
This is a very singular plant, with strong stems, handsome dark-green shining foliage, and fragrant flowers, 
which are of a pale green, with numerous little pink dots on the inside. It is a native of South America, whence it 
1 was introduced in 1838. 
' There are many other species of Passion Flower, but they all require a stove in Great Britain.
