Stylophorum
(from stylos, a style, and phero, I bear; indicating one of the distinctive characters). ORD. Papaveraceae. A genus comprising three species of hardy herbs (nearly allied to Chelidonium, from which they principally differ in habit), with perennial rhizomes and yellow juice; one is North American, a second is Himalayan, and the third is found in Mandschuria and Japan. Flowers yellow or red; sepals two; petals four; stamens numerous; peduncles elongated, solitary or sub-fasciculate, at length nodding. Radical leaves pinnatifid or absent; cauline ones few, alternate, or the floral ones nearly opposite, lobed or dissected. Two species have been introduced to this country. They thrive in any light garden soil. Propagation may be effected by seeds, sown in the open border, during April; or by divisions of the root. S. diphyllum (two-leaved).* Celandine Poppy. fl. deep yellow, 2in. broad; peduncles equalling the petioles. May. l. pale or glaucous beneath, smoothish, deeply pinnatifid into five or seven oblong, sinuate-lobed divisions; radical leaves often with a pair of smaller and distinct leaflets. h. 1ft. North-west America, 1854. The foliage and flower resemble Celandine. (B. M. 4867.) SYN. S. ohioense.
S. japonicum (Japanese). fl. yellow, axillary, Poppy-like. May. l., radical ones long-stalked, pinnatisect. Stem slender, 1ft. to 1 1/2ft. high, two or three-leaved. Japan and North-eastern Asia, 1870. An elegant plant. (B. M. 5830.) SYN. Chelidonium japonicum.
