Description
Summary:We describe in this paper the hybrid genus × Taxodiomeria Z.J. Ye, J.J. Zhang et S.H. Pan, gen. nov. (Taxodium Rich, × Cryptomeria D. Don) and the hybrid species × T. peizhongii Z.J. Ye, J.J. Zhang et S.H. Pan, sp. nov. (Taxodium mucronatum Ten. × Cryptomeria fortunei Hooibrenk ex Otto et Dietr.) (Taxodiaceae). The hybrid originated in Nanjing in 1963 and was introduced into Shanghai in 1975; it has been propagated vegetatively since then. These hybrids, about 2000 in all, were hardly known but are now big trees and highly valued for their fine shape, faster growth rate, and adaptation to urban environments compared to Taxodium and Metasequoia. Morphologically, the hybrid species strongly resembles Taxodium mucronatum, differing slightly in a few vegetative characteristics. 本文对杂交属 Taxodiomeria Z.J. Ye, J.J. Zhang et S.H. Pan, gen. nov. (Taxodium Rich. × Cryptomeria D. Don) 和杂交种 T. peizhongii Z.J. Ye, J.J. Zhang et S.H. Pan, sp. nov. (Taxodium mucronatum Ten. × Cryptomeria fortunei Hooibrenk ex Otto et Dietr.) (Taxodiaceae) 作了描述。该杂种 1963 年在南棄杂交成功，1975 年引入上海，并进行无性繁殖，现有大树约 2000 株。这些杂种过去鲜为人知，但如今因其树形美观，生长速度快于落羽杉属 (Taxodium) 和水杉属 (Metasequioa) 树种且更能适应城市环境，而受到高度重视。该杂种在形态上 与西落羽杉 (Taxodium mucronatum) 很相似，但在一些誉养体特征上与后者有差异。
