 I. of a sea-green colour; oblong, attenuated at the base, cori- 

 aceous, one-nerved, quite entire, sessile. Bark of branches 

 purplish. A. 3ft. to 6ft. Spain, 1596. Hardy. This ia nearly the

BURBIDGEA (named after F. W. Bar- 



bidge, the discoverer of the genus, a traveller 



in Borneo, and author of several horticultural 



works). OED. Scitaminece. A very large, bril- 



liant-flowered stove herbaceous perennial, allied 



to Hedychium. For culture, see Alpinia.

long, slender ; outer segments l}in. to 2in. in dia-

Fig. 302, for which we are indebted to Messrs. Veitch 



and Sons. (B. M. 6403.) 



BURCHARDIA (named after H. Burchard, 

 M.D., a botanical author). OBD. Liliacece. An 

 ornamental greenhouse herbaceous perennial, 

 allied to Androcymbium. It thrives best in 

 sandy peat, or peat mixed with a little loam. 

 Propagated by offsets or divisions, made just 

 previous to potting, in spring. It is best to re- 

 pot annually. Good drainage should be allowed, 

 and the plant must not be potted too firmly. 



B. umbellate (umbelled). fl. white, green. August. 

 A. 2ft. New Holland, 1820. 



BURCHELLIA (named after W. Burchell, 

 a botanical traveller in the Cape of Good Hopu, 

 and in Brazil). OBD. Rubiaceoe. A stove ever- 

 green shrub from the Cape of Good Hope. Flowers 

 scarlet, disposed in heads at the tops of the 

 branches, sessile upon a villous receptacle, in- 

 termixed with small distinct bracteoles; and each 

 head is propped up by the ultimate pair of leaves ; 

 corolla of a clavate-funnel-shape. Leaves ovate, 

 acute, a little cordate at the base, petiolate ; 

 stipules interpetiolar, broad, cuspidate at tha 

 apex, deciduous. It grows well in a rich light 

 soil, or a mixture of turfy loam, turfy peat, and 

 sand. Cuttings, not too ripe, root readily if 

 planted in sand, and placed under a hand glass, 

 in a gentle heat.

required to ensure health and vigour. In the dull days of 

 winter, they should be watered less frequently, but the 

 plants must not be allowed to exhibit the slightest signs of 

 distress from drought, or the consequences may be fatal to 

 their health. When fastening these plants to blocks of 

 wood, a little sphagnum should be used, for experience 

 proves that they thrive best when their thin white roots 

 can escape and hang exposed to the air. If growing them 

 in baskets, it is preferable first to fasten them securely 

 upon small pieces of bare cork, then to fill the basket, 

 and finally to cover the whole thinly with a layer of 

 sphagnum. 



Generally speaking, this genus is not a difficult one to 

 cultivate; its great enemy is a small white scale, which

BUBLINGTONIA (named after the "amiable and 

 accomplished" Countess of Burlington). OBD. OrcMdece. 

 A small genus of epiphytal Orchids, all of which are 

 beautiful and eminently well worth growing. They may be 

 grown upon small blocks of wood, or in rustic baskets, 

 suspended from the roof of the plant stove, where, if 

 liberally treated with water, and a genial moisture in the 

 air during the growing season, very little else will be 



secretes itself in the sheathing bases of the leaves. Here 

 it rapidly multiplies, to the great detriment of the plants ; 

 the leaves soon turn yellow at the base, and drop off ; the 

 whole plant looks sickly, and soon dies, or else requires a 

 very long time and much trouble to achieve its recovery 

 to health. To prevent this, the bases of the leaves must 

 be carefully looked into every time the plants are taken 

 down to be dipped in water ; and, should the slightest 

 sign of this pest appear, a thorough washing with soft 

 soap and tepid water must be given, repeating the opera- 

 tion every day until all traces of the insect are re- 

 moved. Kcd thripa are also apt to work much mischief
