The variety of character exhibited in this new species of Hemerocallis, so different from its congeners, in foliage, flower, and seed; would almost induce us to think like Gærtner, a generic division necessary; if we were not withheld, by that strong rule of Linnæus, (from which, it will be a leading feature of this work, not to swerve) not to increase the number of genera, but where absolutely necessary. This species, as well as a white variety, which has been figured by Kæmpfer; and continued since him by Welldenow, in his new Species Plantarum, under its present denomination; is a native of China, and introduced to our gardens from thence by G. Hibbert. Esq. of Clapham, from whose most extensive and beautiful collection this specimen was taken. It is as yet cultivated as a hothouse plant, where it flowers in the spring months, perfecting its seeds: perhaps when better known, it may be found, like many Chinese plants, to bear our climate. It is propagated as well by parting its roots, as from the seeds.
