峨三七的原植物

1.人参属植物在峨眉山种类較多,当地通称峨三七,为一种名貴药材。作者于1956年間在四川峨眉山調查药用植物时采得各种峨三七,进行了整理研究,确定其属于两个种及两个变种:(1)竹节参P.japonicum Mey.及二变种:狹叶竹节参P.japonicum var.angustifolium(Burk.)Cheng et Chu,comb.nov.及竹叶竹节参P.japonicum var.parvifolium Cheng et Chu,var.nov.;(2)羽叶参P.bipinnatifidum Seem. 2. P.repens Maxim.与P.japonicum Mey.实指一物,Meyer的种发表在前,故本文采用P.japonicum Mey.作为竹节参之正名.并将var.angustifolium轉为本种的变种.将P.wangianum Sun与P.joponicum Mey.合并。

IDENTIFICATION OF THE MEDICINAL SPECIES OF PANAX FROM MT.OMEI,SZECHUAN

In Mount Omei, there are several species of Panax which possess thick and jointed rhizomes and have long been used as prized remedies and tonics by the local inhabitants. Through both field investigation and herbarium studies on the specimens from this mountain, the authors have identified two species and two varieties of Panax that all serve the same purpose. These are: (1) Panax japonicum C. A. Mey.; (2) P. japonicum var. angustifolium (Burkill) Cheng et Chu, comb. nov.; (3) P. japonicum var. parvifolium Cheng et Chu, var. nov.; (4) P. bipoinnatifidum Seem. An analytical key to the species and varieties is as follows: 1. Leaflets deeply pinnatifid or bipinnatifid …………Panax bipinnatifidum 1. Leaflets entire, margin with various dentations. 2. Leaflets rather broad, narrowly elliptical to broad obovate, usually 5 in number……P. japonicum 2. Leaflets long and narrow or lanceolate, usually 7. 3. Leaflets narrow elliptical, 5—12 cm long, 1.7—2 cm broad, membranaceous, semitransparent, with conspicuous setose hairs on the vein ……………P. japonicum var. angustifolium 3. Leaflets lanceolate, rather small, 3—7 cm long, 1—1.5 cm broad, chartaceous, with only scanty setose hairs on the vein…………P. japonicum vat. parvifolium
