Borreria
(named after William Borrer, F.L.S., a profound botanist and cryptogamist). ORD. Rubiaceae. A large genus of stove herbs or sub-shrubs, now referred to Spermacoce. Flowers small, white, rarely blue, disposed in verticillate heads, in the axils of the leaves, or on the tops of the branches, rarely cymose or corymbose. Leaves opposite, or the young ones disposed in fascicles in the axils of the old ones, and therefore appearing verticillate; stipules joining with the petioles, more or less sheathing, fringed by many bristles. Stems and branches usually tetragonal. The species are of easy culture, thriving in a light soil. Cuttings of the perennial kinds strike root readily in the same kind of soil, in heat. The annual kinds require a similar treatment to other tender annuals. B. stricta (straight). A dwarf shrub, but closely allied to the next species. Porto Rico.
B. verticillata (whorled-flowered). fl. white. July. l. linear lanceolate, acuminated, opposite, but appearing verticillate from the fascicles of young leaves in the axils. h. 2ft. West Indies, 1732.
