p. c. 2 angustifbita Hort. has the lobes of the leaves narrow, and 

 flowers rather later than the species. 

 P. c. 3 glaucophylla Hort. has the leaves glaucous beneath. 

 P. c. 4 ^Colvill'ii Swt. Fl.-Gard., 1. 126., has the lobes of the leaves ob- 

 long-lanceolate, and the flowers whitisli, 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. 5 racemdsa Hort. Trans., 4. t. 9., is a hybrid between P. carCllea 

 and the stove species, P. racemfisa, originated in 1820. It has pur. 

 plish flowers ; and is not so hardy as P. cferulea. 

 P. incarnata L. [Bot. Reg., t. 3.32.; and oury?g. 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 

 groundevery year ; on which account the roots, or stool, may, with 

 the greater ease, be preserved against a conservative wall. 



P. Uliiefhlia L., the Lime-tree- leaved Passion Flower, is a native of 

 Peru, with cordate entire leaves, red flowers, and fruit globose and 



variegated with red and yellow. It was introducedjn 1823, and is considered nearly as hardy as P. 

 ca^riilea. 



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. 



Disemma ndiantiftlia Dec; Passiflbra.adiantifdlia 

 Sot. Reg., t. 233. ; and Q\xr fig. 711. ; is a splendid 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.

Tacsunia pinnatistipula Juss., Swt. Fl.-Gard., new 

 series, 2. t. 156. ; Passiflbra pinnatistipula Cav. ; is a 

 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 T. pinnatistipula on Passiflbra cEeriilea. 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.

OF THE HARDY AND HALF-HARDY SPECIES OF THE ORDER 

 CRASSULA'CEiE. 



SE'DUMpojmnfolium L. (JVtlld. Sp. PL, ii. p. 762., Bot. Mag.,t. 211.); the 

 Poplar-leaved Sedum, or Stonecrop ; ^nacampseros yjopulifolia Haworth St/n. 

 Plant. Sue, 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 apiary. 



Sempervh'um arbbrewn L., the Tree Houseleek, (Bot. 

 Reg., t. 29. ; and our fig. 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 loaves which 

 take a rich brown in summer or autumn.
