BOUNCING BET. See Saponaria officinalis. 
BOURBON ROSES. Hardy, free-flowering, vigorous 
Roses, descended from Rosa indica Bourboniana. Souvenir 
de la Malmaison is still one of the best varieties. 
BOURRERIA (named in honour of Bourrer, a 
Nuremberg chemist). Syns. Beurreria, Crematomia. ORp. 
Boraginex. A genus embracing sixteen or eighteen species 
A distinct variety, having 
Bordeaux 
of stove trees or shrubs, natives of the West Indies, 1 
Mexico, Central America, &c., and closely allied to 
Ehretia. Flowers whitish, often larger than in Ehretia. 
Leaves alternate or rarely somewhat whorled. Two of 
the species have been introduced, but they are of no 
great horticultural value. 
BOURSAULT ROSES. Vigorous climbing Roses, 
descended from Rosa alpina. 
BOURSE. This word, of French origin, has been 
applied to some peculiar swellings frequently seen upon 
trees and shrubs, and due to physical changes. On fruit 
trees, such as Apples and Pears, they are often found, and 
may be said to consist of nutritive elements stored up for 
the development of the fruits, but which, owing to the wood 
in the vicinity being killed, do not reach the growing point. 
BOUSSINGAULTIA. The ten species included in 
this genus are all natives of tropical America. Flowers 
small, hermaphrodite, on short or slender pedicels, disposed 
in axillary and terminal racemes. Leaves alternate, 
petiolate or almost sessile, ovate, elliptic or cordate, more 
or less fleshy, entire. To the species described on p. 206, 
Vol. I., the following should be added : e 
B. cordata (cordate). A succulent climber, nearly allied to 
B. baselloides. Peru, 1895. 
BOUTELOUA (named in honour of Estéban Boutelou, 
1776-1813, Professor of Agriculture at Madrid, and Claudio 
Boutelou, 1774-1842, Director of the Botanic Garden at 
. Madrid), Syns. Actinochloa, Eutriana. Including 
Atheropogon. ORD. Graminex. A genus embracing about 
twenty-five species of annual or perennial Grasses, all 
American. Spikelets unilateral, one- or two-flowered ; 
glumes two, acute, carinate ; spikes usually numerous, at the 
side of the peduncle, rarely reduced to a single, terminal 
one. B. racemosa (Syn. Atheropogon apludioides) has been 
introduced, but is of no particular horticultural value. 
BOUVARDIA. Syn. £ginetia. This genus com- 
prises about twenty-six species of herbs and shrubs, mostly 
Mexican. These choice greenhouse flowers are being more 
sought after year by year, owing to their great value 
for late autumn and winter flowering, especially for the 
making up of small bouquets, buttonholes, and for table 
decoration. To the species, &c., described on p. 207, 
Vol. I., the following should be added : 
B. longiflora flammea (flame-coloured). 4. large, with a rosy- 
pink tube and salmon-coloured lobes. 
B. seabra (scabrous). jl. bright pink, sin. in diameter, freely 
roduced in dense, corymbose cymes; corolla tube fin. to lin. 
ong, the lobes elliptic-ovate, somewhat acute. January. J. in 
distant whorls of three or rarely four, ovate, acuminate, 
narrowed to a very short petiole; lower ones 2in. to 3in. long, 
lin. to 14in. broad, the upper ones gradually smaller. Stems 
terete, herbaceous, hairy, lft. to 1ift. high.
