P. c. 2 angustifolia Hort. has the lobes of the leaves narrow, and 
flowers rather later than the species. 
P. c. 3 glaucophglia Hort. has the leaves glaucous beneath, 
P. c. 4 Colvillii Swt. Fi.-Gard., t. 126., has the lobes of the leaves ob- 
long-lanceolate, and the flowers whitish, tinged with blue and purple. 
It is a hybrid, which was raised in Colvill’s Nursery ; and it is consi- 
dered as hardy as the species. 
P.c. 5racemdsa Hort. Trans., 4. t. 9., is a hybrid between P. cerdlea 
and the stove species, P. racemdsa, originated in 1820. Ithas pur- 
plish flowers ; and is not so hardy as P. cerulea. 
P. incarnata L. (Bot. Reg., t. 332.; and our jig. 710.), the flesh-co- 
loured Granadilla, or May Apple, is a native of South America and 
Virginia, with flesh-coloured flowers, and fruit about the size of a small 
apple, orange-coloured, with a sweetish yellow pulp. It may almost 
be considered as herbaceous, as the shoots die down nearly to the 
ground‘every year ; on which account the roots, or stool, may, with 
the greater ease, be preserved against a conservative wall. 
P. tiliefilia L., the Lime-tree-leaved Passion Flower, is a native of 
Peru, with cordate’entire leaves, red flowers, and fruit globose and 
rare with red and yellow. It was introduced,in 1823, and is considered nearly as hardy as P. 
cerilea, 
Other species or varieties, to be found in British ca- 
talogues and gardens, may, perhaps, be as hardy as 
some of those above mentioned ; and, as they are all 
eminently beautiful, we recommend them to be tried 
against a conservative wall as extensively as possible. 
Disémma adidntifolia Dec. ; Passifldra. adiantifolia 
Bot. Reg., t. 233. ; and our fig. 711. ; is asplendid twiner, 
a native of Norfolk Island, introduced in 1792; and, 
though not very common, it is highly probable that 
it would thrive against a conservative wall. The leaves 
are lobed, and the flowers yellow at first, becoming at 
length of an orange colour, with the inner crown green, 
and longer than the purple rays that surround it. 
(Don’s Miil., 3: p. 56.) 
Tacsdnia pinnatistipula Juss., Swt. Fl.-Gard., new 
series, 2. t. 156.; Passifldra pinnatistipula Cav.; isa 
climbing shrub, a native of Chili, introduced in 1828. 
The leaves are white from velvety down on their 
under surface; the stipules are pinnate ; and the flow- 
ers rose-coloured, or purplish, with the crown a.deep blue. The plant, which is exceedingly beau- 
tiful, has flowered magnificently, and ripened its round yellow fruit, in the conservatory of Mrs. 
Marryat, at Wimbledon; and it has flowered on the open wall of the garden of Englefield House, 
near Reading. There are several other species of this genus, but they have not yet been introduced. 
Hybrids will, no doubt, be raised between this genus and Passifldra; and perhaps something might be 
gained in hardiness by grafting 7. pinnatist{pula on Passifldra cerilea. ‘The flexible shoots of all the 
plants noticed in this chapter admit so readily of protection, by tying them in bundles, and envelop- 
ing them in straw and matting, that no conservative wall ought to be without them. 


CHAP. LI. 
OF THE HARDY AND HALF-HARDY SPECIES OF THE ORDER 
CRASSULA‘CEZ. 
Sz\pum populifblium L. (Willd. Sp. Pl., ii. p. 762., Bot. Mag.,t. 211.); the 
Poplar-leaved Sedum, or Stonecrop; Anaeampseros populifolia Haworth Syn. 
Plant. Suc., p. 113.; is a hardy miniature shrub, a native of Siberia, which was 
introduced in 1780, and flowers in July 
and August. It is remarkable as being 
truly ligneous in a genus the other species 
of which are nearly all herbaceous. The 
flowers are white, and are particularly 
grateful to bees, whence this shrub is well 
adapted for planting near an aplary. 
Sempervivum arbireum L., the Tree Houseleek, (Bot. 
Reg., t. 29: ; and our Sig. 712.) is a native of Portugal, 
Barbary, and Candia, where it grows to the height of 
5 ft. or 6 ft.; producing its yellow flowers from March 
to December. It is an old inhabitant of our green- 
houses, and, with the proper protection, would stand 
against a conservative wall. There are two varieties : 
one with variegated leaves, and one with leaves which 
take a rich brown in summer or autumn,
