This new species, of Thunberg’s new genus Sanseviera, which is a branch of the Linnæan genus Aletris; was introduced into this country from China, by T. Evans, Esq. of Stepney; in the year 1792: but is still very rare. Our drawing was made from a fine plant in the collection of J. Vere, Esq. of Kensington Gore, in the month of March[A]. Mr. Anderson, his botanic gardener, informs us, he has treated it as a hothouse plant; but it will probably be found to succeed better in the greenhouse, like other Chinese plants. It is propagated by parting the roots. In habit it resembles Hemerocallis more than Sanseviera, but agrees with the generical characters of Sanseviera zeylanica. With Aletris fragrans it also agrees in many particulars; but with Aletris farinosa is quite at variance. [A] A root of it, (lately parted from the individual here figured,) flowered at Messrs. Grimwood and Wykes’s, in February. [Illustration] PLATE CCCLXII. CROCUS BIFLORUS. _Yellow-bottomed White Crocus._ CLASS III. ORDER I. _TRIANDRIA MONOGYNIA._ Three Chives. One Pointal. ESSENTIAL GENERIC CHARACTER. COROLLA, supera, 6-partita, subæqualis, erecto-patula, tubo longissimo subterraneo. COROLLA, above, 6-parted, nearly equal, erect-expanding, with a very long subterraneous tube. SPECIFIC CHARACTER, &C. Crocus, foliis angustissimis effusis floribus semper longe superantibus. Crocus, with very narrow diffused leaves, which are always much higher than the flowers. DESCRIPTIO. _Radix_ tunicis glabris cochleariformibus. _Folia_, tempore florendi, longissima omnium, magisque effusa. _Spathæ_ sæpe 2-floræ, ut in plurimis. _Flores_ vernales, albæ, magnæ; fundo intus sordide flavo, extus aliquo olivaceo; tubo pergracili, depilato; petalis 3 exterioribus, extus tincturâ flavedinis, et purpureo elegantissime plumoso-striatis. _Filamenta antheræque_ erectæ, luteæ. _Stylus_ percroceus. _Stigmata_ itidem percrocea, antheris vix superantia. _Haworth’s Crocus inedit._ REFERENCE TO THE PLATE. 1. The outer sheath of the flower. 2. The inner. 3. The flower cut open. This beautiful Crocus is unquestionably distinct as a species, and has never been noticed by any systematic writer except Miller; who has described it accurately under the name of _biflorus_, in the 8th edition of his celebrated Dictionary. It is very hardy, flowers early in February, and may be readily distinguished from other Crocuses by its leaves being much longer than the flowers, at the time of flowering. When the sun shines strong, the flowers have a just perceptible fragrant scent; a circumstance very unusual in this genus; all the other species, (one we call _fragrans_ excepted) having more or less of an unpleasant smell. It seldom produces seeds in this country, or varies in colour; but increases by the root. [Illustration] PLATE CCCLXIII. POLYGALA STIPULACEA. _Stipuled Milkwort._ CLASS XVII.
