 with these plants. They take up their abode in the same 

 way as the white scale, and if not speedily removed or 

 destroyed, soon make sad havoc. To put a stop to the 

 ravag"es of this pest, a wash should be given, as before 

 recommended, and after the soap has been rinsed out of 

 the base of the leaf, a little tobacco powder should be 

 sprinkled into the hollows, and allowed to remain for a day 

 or two before brushing it off. This process will, however, 

 cause a somewhat dirty appearance, but it will ensure 

 ultimate health and vigour. Propagated by dividing the 

 plants. 



B. Batemannl (Bateman's).* Jl. white, deliciously-scented ; lip 

 beautiful mauve. A very pretty South American species, re- 

 st'uiblin;; B. Candida. 



B* Candida (white).* Jl. snowy-white, with a slight stain of 

 yellow on the upper part of the lip, in substance and appearance 

 like white satin, trinmied with gold ; large, sweet-scented, in 

 gracefully drooping three to four-blossomed racemes, produced 

 from the axils of the leaves. April and May, lasting about three 

 weeks in perfection, and sometimes having a second flowering 

 season. I. one or two in number, dark green, and firm in texture. 

 h. lit. Demerara, 1834. A very compact species, well suited for 

 basket culture ; it should never be allowed to get dry. It may 

 be distinguished from other species by having a single row of 

 tubercles, forming a ridge upon each side of the slightly hastate 

 lip. (B. R. 1927.) 



B. decora (comely).* jl. white or rose-coloured, spotted Tivith red ; 

 lip pure white ; scapes erect, five to ten-flowered. Winter. 

 Brazil. 1852. This species differs entirely from B. Candida, in- 

 asmuch as it possesses a long slender-rooting stem, from different 

 fiarts of which arise small oval pseudo-bull is. each bearing a 

 eaf ; a lesser leaf appears at the base of a biUb, and from the 

 axil of this the scape springs. It is a rather straggling but never- 

 theless beautiful s]>ecies, and is best grown fastened upon long 

 strips of cork, a little sphagnum being used in the operation; 

 whilst, to prevent the plant getting too much "away from home," 

 the young growths should be twisted back as they advance, and 

 the practice continued until the pseudo-bulb is ultimately left 

 near the centre, or in any spot which may appear bare. It likes 

 strong heat and a very moist atmosphere, when growing ; but 

 during the period of rest, it should be kept cool and dry. See 

 Fig. 303. (B. M. 4834.) 



B. d, plcta (painted).* A beautiful variety, differing from the 

 type in having shorter and more acute leaves ; flowers produced 

 in greater profusinu, rose-coloured, lieautifuUy mottled and 

 blotched with dark purple. October. Brazil. (B. M. 5419.) 



B. fragrans (fragrant).* Jl. very gratefully frafrrant, disposed 

 in erect racemes. April, remaining in perfection about three 

 weeks, l. long, rigid, dark green. Habit compact. Brazil, 1850. 



B. pubescens (downy), yf., sepals and petals snow-white; dis- 

 tinguished by the somewhat hastate lip, which has three yellow 

 ridges on each side, and also by the downy column. November. 

 h. 6in. Brazil, 1850. 



B. rigida (rigid).* jl. purplish-white, spotted with pink on the 

 lip ; produced in heads, h. 1ft. Brazil, 1838. A handsome 

 plant, but difficult to flower. (L. S. O. 36.) 



B. venusta (charming).* /. white, slightly tinted with pink ; 

 produced in heavy pendulous clusters at various seasons of the 

 year ; lip stained with yellow. I. rigid, dark green. Brazil, 1840. 

 It forms a compact mass, and requires less heat than the kinds 

 previously described. It is often confounded with B. pubescens, 

 from which it may be distinguished by its larger and more loosely 

 arranged flowers, by its smooth column, by the lip not being 

 hastate in shape, and by the numerous shallow ridges borne near 

 the base upon each side. (L. S. O. 2.) 



BUR MARIGOLD. See Bidens.

BTTBiNZST (Potei-ium Sanguisorba ; from poterion, a 

 cup ; being used in cooling drinks). Ord. Rosacem. A 

 native perennial. Tlie leaves are sometimes used in soups, 

 and with Borage in cooling drinks ; they are also put in 

 salads. The foliage only being useful, keep the flower- 

 8pikes removed, as this tends to increase the luxuriance 

 of the plants. It thrives in any light soil. Propagated by 

 division.

 very much resemble those of the Shepherd's Purse). Oed. 



Bnrsaria — continued. 

 Pittosporacece. A handsome, mueh-branehed, greenhouse 

 evergreen shrub, forming a very pretty object when covered 

 all over with its elegant white blossoms. It thrives well 

 in a compost of sandy loam and peat, in equal proportions. 

 Young cuttings will root freely in sand, under a beU glass, 

 with a little bottom heat. 



B. splnosa (thorny).* a. white, sniaU. disposed either in lateral 

 or terminal panicles. July to December, /. small, ohlong-cune- 

 ateil, entire, h. lOtt. New Holland, 1793. (B. M. 1757.) 



BURSERA (named after Joachim Burser, a disciple 

 of Caspar Bauhin). Okd. Burseracem. Stove balsam- 

 bearing trees. Flowers polygamous, or hermaphrodite ; 

 calyx small, four to six-toothed ; petals four to six, spread- 

 ing, generaUy valvate in aestivation; stamens eight to 

 twelve ; disk annular, with usually six to ten teeth ; drupe 

 oblong, covered by a three-valved succulent rind, contain- 

 ing three to five nuts. They thrive in a compost of loam 

 and peat. Propagated by cuttings, placed under a glass, 

 with bottom heat. 



B. gnmmlfera (Kura-bearing). Jl. whitish, hexandrous ; racemes 

 terminal and axillary. I. deciduous, usually impari-pinnate ; leaf- 

 lets ovate, acute, membranous, h. 60ft. West Indies, 1690. 



B. serrata (serrate).* .rt. whitish, decandrous ; panicles axillary, 

 shorter than the leaves. I, impari-pinnate, with three to hve 

 pairs of broad-lanceolate, bluntly-acuminated, serrulated leaflets ; 

 petioles and pedicels pubescent, h, 25ft. India, 1818. 



BURSERACEJB. An order of shrubs or trees, abound- 

 ing in resinous juice ; with opposite compound leaves, full 

 of pellucid dots, and axillary and terminal fascicles of 

 flowers. Fruit indehiscent, somewhat drupaceous. The 

 genera best known are Amyris, Balsamodendron, Bosivellia, 

 Bursera, and Canarium. 



BURTONIA (named after D. Burton, a plant collector 

 for Kew Gardens). Ord. Leguminosce. A genus of hand- 

 some greenhouse dwarf Heath-like shrubs, natives of West 

 Australia. Flowers axillary, often thickly gathered at the 

 ends of the branches; coroUas rich purple; keel generaUy 

 of a deeper colour, and the standard having sometimes 

 a yellow blotch at its base. Leaves simple or trifoliolate, 

 sessile, usually awl-shaped. They thrive well in a mixture 

 of loam, peat, leaf soil, and sand, in equal proportions, with 

 thorough drainage ; but care must be taken not to give 

 them too much water, as they require to be kept moderately 

 dry, and are difficult to preserve in a living state. Young 

 cuttings root freely in a pot of sandy soil, in a cool house, 

 with a bell glass placed over them ; but some of the species 

 produce seed in abundance, which are the best means of in- 

 creasing them. 



B. conferta (cluster-flowered).* Jl. violet. July. I. simple, 

 very much crowded, six to ei^ht lines loiiEr, linear-subulate, with 

 revolute margins, and are, as well as the branches, smooth. 

 h. 2ft. 1830. (B. E. 1600.) 



B. minor (smaller). A synonym of Gompholoiium minus. 



B. pillchella (beautiful). A synonym of B. scabra. 



B, scabra (rou'ili).* Jl. purple ; peduncles axillary, bi-bracteate. 

 April. L, leaflets glabrous, lincar-nuicronate. Branches puberldous. 

 h. 2£t. 1846. Syn. B. pvlchella. (B. M. 5000.)

 pedicels, and fitrnished with two bracteoles each, under 

 tho calyx ; corolla deep scarlet ; down on the calyces 

 usually black and velvety. Leaves pinnatoly-trifoUate; 

 leaflets large, ovate, roundish, stipellate. For culture,
