Pseudognaphalium canescens (DC.) A. A. Anderberg

Comments ( 英語 )

由eFloras提供
Most plants of Pseudognaphalium canescens produce white, opaque, keeled, apiculate phyllaries; in the southern portion of its range (Jalisco southeastward) and scattered localities elsewhere, the phyllaries may be more hyaline and lack a pronounced keel and apiculum.
