Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 802 INCAEVILLEA INDIANA INCAKT/lLLEA (after Incarville, the French Jesuit missionary to China). Bignonidceit. About 10 species of herbaceous perennials from central Asia, one of "which, /. Delavat/i, has achieved extraordinary notice since 1893. It is a hardy plant with handsome pinnate foliage, each leaf being 1 ft. long, with as many as 15-20 dentate segments: scape 1-2 ft. high, bearing 2-12 large trumpet-shaped, rosy purple fls., each 2-3 in. long and as much wide. These fls. are probably equal in decora- tive value to many of the Bignonias cherished in our greenhouses. In size and beauty they rank with those of Catalpa, Bignonia and Tecoma, of the same family. This species is certainly the finest hardy hei'baceous perennial in the Bignonia family. The tube is yellow inside and out, and the 2 upper lobes are smaller than the 3 lower ones. The genus is closely allied to Amphi- come, and the flowers of both have the same genenal ap- pearance, but in Incarvillea the calyx lobes are awl- shaped, while in Amphicome the calyx is truncate or shortly dentate. Also the seeds of Incarvillea have an entire hyaline wing, while in Amphicome the seeds have a wing thai is cut into long thin, strips or hairs. The rwo genera form a small but remarkable group, charac- terized by their capsules opening by the ventral suture only. William Watson declares that Inearvilleas are not annuals, as stated in the botanies. The general experience seems to be that these plants need rather more winter protection than most hardy herbaceous perennials. A light, sandy loam, well en- riched and deeply worked, suits them well, and they like a sheltered position in a rather warm, sunny place. Prop, by division
