SOEIiXA (named in bonoar of William Boell, Pro- 

 fessor of Anatomy at Ami?terdam). Okd. Campanularfix. 

 A genns comprising eleven species of preenhooge, rigid 

 mb-shrnbe or email, diffac« herbs, confined to Sontb 

 Africa. Flowers sessile within the imbricating lea^e*. 

 solitary or glomerate : calyx with an adnate, oblong or 

 cylindrical tabe and a five-parted limb, the lobes often 

 toothed : corolla campannlate or fannel-shaped, fire-lobed. 

 Leaves scattered, small or narrow, often rather rigid 

 and fascicled at the axils, entire or ciliate ■ toothed. 

 Several of the species have been introduced, bat that 

 described below is the most desirable. A compost of 

 sandy loam and peat is most snitable for its coltare. 

 Propagation may be effected by seeds ; or by yoong 

 cuttings, which will root freely in the soil above-named, 

 if a hand glass be placed over them.

 heads and penniveined leaves, tiative of tropical America. 

 It is probably lost to cultivation. 



BOLIiEBS ASS BOLUVO. For keeping walks 

 firm and in good condition, an iron Boiler is requisite in 

 gardens. The size must be determined by the extent 

 and width of the walks to be Rolled. New gravel 

 walks should always have a light Boiler passed over them 



Boilers and Boiling — conh'nued. 

 first, and a heavy one afterwards. Others, if they are 

 firm, and have been well made in the first place, should 

 bear a heavy weight always. Boilers of almost any size 

 may be obtaine<l in iron up to several hundredweights. 

 Boiling should only be practised when walks are suffi- 

 ciently dry to keep the gravel from clinging; the proper 

 time frequently does not last long, and, when walks are 

 rough, an opportunity for Boiling them should not be lost.

BOMANZOFFIA (named in honour of Count Bo- 

 manzov, a Ka.s.sian nobleman, who was a patron of scien- 

 tific studies). Oed. Hi/drophyllaretx. A genus consist- 

 ing of only two species of low. tufted, hardy perennial 

 herbs, having much the appearance of Saxifrage* : they 

 inhabit the sub-arctic regions of Eastern Asia and 

 Western America. Flowers white, unilaterally racemose ; 

 calyx segments five ; corolla broadly or tubularly cam- 

 pannlate with five imbricated, spreading lobes ; stamens 

 five, affixed to the base of the corolla. Radical leaves 

 long-stalked, canline ones very few. orbicular-reniform, 

 deeply toothed. R. tiUheneig. the only species intro- 

 duced, is a suitable subject for planting un rockwork. 

 It requires much the same culture as Saxi&aga (which

 Robii.-.^ii. aii a-tronomer. of Armagh). Oed. Papa- 

 feracece. .\ monotypic genus. The species is a tall, showy, 

 branched, glabroas, herbaceoiLs perennial, allied to Plaly- 

 gtigma. Although a half-hardy plant, it nevertheless 

 thrives best, and produces larger and more abundant 

 Sowers if allowed space in a cool greenhouse. A rich, 

 sandy loam soil is most suitable. The species may be 

 increased by means of seeds, sown in the spring.

BOMTTIiEA (a name commemorative of Romulus, 

 the mythical founder of Rome). Sts. Trichnnema. In- 

 cluding Spatalanthus. Oed. Iridem. A genns of pretty, 

 greenhouse or hardy, bulbous plants, natives of Western 

 Europe, the Mediterranean region, and South and West 

 Africa. Fifty-four species have been eniunerated, but, 

 according to the authors of the " Genera Plantarum," 

 many of these are reducible to mere varieties. Mr. Baker, 

 in his review of the gentLs published in the " Journal of 

 the Linnean Society," xvi. 86, accords specific rank to 

 thirty-six. Flowers one to a spathe, sub-sessile or 

 shortly pedicellate : perianth funnel-shaped, with a very 

 short, or rarely elongated, tube, and equal, erecto-patent, 

 entire lobes ; stamens affixed to the throat : spathes long- 

 pedunculate in the axils of the floral leaves ; bracts 

 beneath the ovary at the apex of the pedicel shorter, and 

 sometimes broader, than the spathe. Badical leaves 

 linear, sometimes subulate, the sheaths rarely lanceo- 

 late-dilated; canline leaves similar, but smaller. The 

 species described below are those best known to cultiva- 

 tion. They require to be planted out in a pit or frame, 

 in a compost of .sandy loam and peat. Propagation may 

 be effect.."! by offsets.
