BREWERIA. 



red, burning readily when lighted. Taste bitter, balsamic. Yields by 

 distillation an essential oil of bitter balsamic flavour; little used, except, 

 according to Fee for adulterating oil of Roses. (Lignum rhodium Officin.) 

 N.B. This plant is said {Rom. and Sch. iv. 300.) to have a 1-celled 

 1-seeded capsule opening at the base. If so it is not more a Breweria 

 than a Convolvulus. But it is so extremely like a Breweria found in 

 Arabia by Fischer (No. 53.) that I cannot but suspect some mistake in 

 this point.

Herbaceous. Stems erect, towards the extremities variously bent, 

 decumbent, and sometimes rooting near the base, round, glabrous, some- 

 what flexuose. Leaves short, petioled, lanceolate, rather obtuse, smooth, 

 bright green above, below marked with numerous prominent parallel veins. 

 Racemes axillary, somewhat leafy, spreading, few-flowered ; every part 

 of them, raches, pedicels, and calyx, glanduioso-pubescent. Pedicels 

 1-flowered, usually opposite to a small bracteal leaf; but sometimes a 

 little either above or below the opposed leaf, rarely axillary. Flowers 

 deep blue, with a white spot in the centre. Calyx 5-parted ; divisions 

 lanceolate, acute, nearly as long as the corolla, thickly covered with 

 glandular hairs. Corolla wheel-shaped ; tube short ; limb 5-cleft ; 

 divisions obtuse, spreading, or even somewhat reflexed when fully open. 

 Stamens 5, alternate with the segments of the corolla. Filaments the 

 length of the tube, attached to it by a dilated base. Anthers large, 

 sagittate. Ovary superior, 2-celled : styles 2, diverging, about the 

 length of the stamens, dark-blue, with paler capitate stigmas. Capsule 

 inclosed in the permanent calyx, 2-celled, many-seeded. Seeds 

 growing all round a large fleshy receptacle, which forms part of the 

 partition. Wight and Arnott. — The leaves beaten into pulp and applied 

 as a poultice are in India considered efficacious in cleaning and healing 

 ill conditioned ulcers, particularly those in which maggots have begun 

 to breed. Wight.
