-
摘要: 产自鄂西北神农架的北萱草植物一直被误定为萱草。笔者对产自神农架燕子垭的萱草属植株进行了栽培实验和核型分析。结果表明所研究的植株为北萱草而非萱草。北萱草通常分布在华北,故在神农架为新分布记录。Abstract: Plants of Hemerocallis esculenta in Shennongjia mount in northwestern Hubeihave long been identified as H. fulva in the literature. In the present work,plant cultureexperiment and karyotype analysis of the plants from Yanziya (alt. 2100 m) located atShennongjia mount are carried out. The results show that the plants observed are not H. fulva, but H. esculenta, which is usually found in northern China. H. esculenta istherefore a new recorded species in Shennongjia mount.
