Botany loves to honor other branches of science as well as its own. Bouvard, after whom, Salisbury, in 1806, made Bouvardia, was an astronomer. It belongs to the Cinchona-ceous division of Rubiaceae. They are Mexican plants. B. flava was introduced in 1845; B. leiantha, B. longiflora, and B. Humboldtii, are types of the different sections. In 1857, Parsons, of Brighton in England, crossed longiflora and leiantha, and gave us "Laura," Hogarth, and others. In 1867, Lemoine, of Nancy, in France, made a long march on these. New York came with its white ones, Davisonii and Vreelandii, in 1852, but it seems to have taken some time to get them known in England. The Kentucky work of Nanz & Neuner. however, has made the greatest mark on the de velopment of the Bouvardia. They and Lemoine still keep at the head of the work in improving this almost indispensable florists' flower. The latter firm sent out a number of varieties in 1884.
