Notes on Gymnosperms I. Taxonomic Treatments of Some Chinese Conifers

A new species, Taxus fuana Nan Li & R. R. Mill, and two new varieties, Abies ferreana Borderes & Gaussen var.longibracteata L. K. Fu & Nan Li and Pinus kwangtungensis Chun ex Tsiang var.varifolia Nan Li & Y. C. Zhong, are described.Thirteen new combinations are proposed in the genera Abies, Keteleeria, Larix, Picea, Pinus, Pseudotsuga, Tsuga, Cephalotaxus, and Taxus.During the revision of gymnosperms for the Flora of China, and as a result of the examination of types and other specimens in some of the major herbaria in Europe and the United States, the following tax¬ onomic novelties are proposed.Abies ferreana Borderes & Gaussen var.longi¬ bracteata L. K. Fu & Nan Li, var.nov.TYPE: China.NW Yunnan: high mountainous belts, ca.3950 m, Zhongdian Expedition 1980 (holotype, PE).A var. ferreana recedit strobilorum bracteis exsertis, non recurvatis, apice attenuatis.The new taxon is readily distinguished from va¬ riety ferreana by having distinctly exserted, acu¬ minate bract scales that are lanceolate at the apex and neither reflexed nor recurved.In contrast, va¬ riety ferreana has usually reflexed or recurved bract scales that are rounded at the apex with an acute cusp.
