Description. A small bush 3 or 4 feet high, with stiff, slender, 

 somewhat angular branches ; bark smooth, reddish-purple ; 

 young twigs covered with immersed oil-glands. Leaves opposite 

 or sub-alternate, shortly stalked or rarely sub-sessile, oval, 

 oblong, or rhomboidal-oval, rather thick, glabrous on both sides, 

 bluntish at the apex, narrowed at the base, f 1J inch (usually 

 about an inch) long, with a marked midrib and a few curved lateral 

 veins, finely serrate or crenate- serrate, under surface paler and 

 sprinkled with immersed oil-glands, one of which also stands in 

 each serrature. Flowers solitary, at the ends of short lateral 

 branches and in the axils of their small leaves, the terminal flowers 

 opening first, true pedicels thickened upwards, a little longer than 

 the calyx, with two or three ovate, ciliated, transparent bracts 

 below the flower. Calyx deeply cut into 5 lanceolate- triangular, 

 acute segments, each with a thick midrib and finely ciliated 

 margins. Petals 5, imbricated, two or three times as long as the 

 calyx, ovate, blunt, spreading, glandular-punctate on the back, 



* From an error in the synonymy in the Bot. Mag., it is made to appear 

 that Willdenow is the authority for B. crenulata. He has no species with that 

 name.
