Pyrola — continued. 

 perennial, very glabrous, stolon - bearing, stemless or 

 caulescent herbs (one species leafless), natives of Europe, 

 (Britain), North and Central Asia, and North America, 

 including Mexico. Flowers white, yellow, pink, or pale 

 purple, on erect, bracteate, racemose scapes, nodding ; 

 calyx five-parted, persistent ; petals five, concave, sessile, 

 more or less incurved-connivent ; stamens ten. Leaves 

 radical or cauline, alternate, usually long-stalked, per- 

 sistent, entire or serrated. Several species are very 

 pretty, and well worth growing. They thrive in thin, 

 mossy copses, on light, sandy, vegetable soil, or in moist 

 and half-shady parts of the rockwork or fernery. Pro- 

 pagated by division. 



P. elllptlca (elliptic). J!, white, canipitnulate, with a grateful 

 .smell ; racemes elongated, few-fluwered, rather secimd. June 

 and July. I. cuneate-oblong, coriaceous, acute at base, twice 

 as long as the narrow petioles, the margins remotely toothed or 

 quite entire, h. 6in. North America, 1818. (H. F. B, A. 131.) 



P. maculata (spotted). A synonym of Chimaphila maculata. 



P, media (intermediate). Jl. white, tinned with red, Ain. in 

 diameter ; racemes many-flowered ; pedicels scattered. * July 

 and August, l. orbicular-ovate, crenate, sometimes l^in. in 

 diameter, h. 4in. Europe (Britain). (Sy. Pin. B. 897.) 



P. minor (smaller). Jl. white, tinged with red, drooping, globose, 

 iin. in diameter; raceme short ; scape Bin. to 12in. long, slender. 

 June to August, l. orbicular-ovate, obscurely crenate, usually 

 arrangeil in a rosette, but sometimes alternate, coriaceous, Iin. to 

 liin. long, contracted into the longer petiole. Europe (Britain), 

 North America. (F. D. 55 ; Sy. En. B. 898.) 



P. rotundifolia (round-le.ived).* Jl. pure white, fragrant, from 

 ten to twenty in a drooping raceme on an erect stem 6in. to 12in. 

 high. Summer. /. roundish, quite entire or crenulated, shorter 

 than the dilated petioles, h. 6in. Europe (Britain). (F. D. 1816 ; 

 Sy. En. B. 895.) The variety arenaria (Sy. En. B. 896), found 

 on sandy sea - shores, differs from the type in having smaller 

 leaves, and pedicels as long as the ovate sepals, and, generally, 

 several scale-like bracts below the inflorescence. Both the type 

 and its variety are exceedingly pretty plants for rockwork, and 

 prefer a sandy soil.

FYRpULABIA (a diminutive from Pi/rus, the Pear; 

 in allusion to the form of the fruit, which, in the 

 original species, is like a smaU Pear). Stns. Hamiltonia, 

 Sphcerocarya. Ord. Santalacew. A genus comprising 

 only a couple of species of deciduous trees or shrubs, 

 one North American, the other Himalayan. Flowers 

 cymulose at the tips of the branches, or in the upper 

 axils ; cymelets forming a terminal, compound raceme, 

 or a raceme-like panicle ; fertile ilowers usually few at 

 the tips of the branches, often twin or solitary. Drupe 

 ovoid or sub-globose, rather large. Leaves alternate, 

 shortly pedicellate, membranous. The only species in 

 cultivation is a half-hardy shrub ; it thrives in sandy 

 loam, and may be increased by cuttings.

 spike small, few-flowered, terminal. May. Jr. Iin. long. I. ob- 

 ovate-oblong, acute, or pointed at both ends, soft, very veiny

 Pear-tree). Apple, Pear, Service, &c. Including Mahis 

 and Sorbus. Cydonia and Mespihis are also included, by 

 Bentham and Hooker, under this genus ; but, for horti- 



Fyms — continued. 

 cultural purposes, they are kept distinct in this work. 

 Some of the plants met with in gardens under the 

 generic name of Aronia belong here. Ord. Kosacece. 

 A genus comprising from thirty-five to forty species of 

 hardy trees or shrubs, inhabiting the temperate regions 

 of the Northern hemisphere, and the mountains of the 

 East Indies. Flowers in terminal cymes, rarely corym- 

 bose, or reduced to one or two flowers ; bracts subulate, 

 deciduous ; calyx tube urceolate or rarely turbinate ; 

 petals five, sub-orbiculate, shortly unguiculate. Fruit 

 fleshy, ovoid, globose, or pyriform. Leaves alternate, 

 deciduous, petiolate, simple or pinnate, often serrate ; 

 stipules deciduous. The species are readily raised from 

 seeds, in the way mentioned under Apple and Fear ; 

 the garden varieties and weaker-growing, ornamental 

 species are most readily propagated by grafting or bud- 

 ding on the Apple or Pear stocks. Except where other- 

 wise .stated, the flowers in the under-mentioned species 

 are white.
