RUBINA ABID AND M. QAISER*
Abstract

---

Cypsela morphology of 8 taxa of the genera Gamochaeta Wedd., Gnaphalium L., Homognaphalium Kirp., and Pseudognaphalium Kirp., was examined from Pakistan using light and scanning electron microscopy. The cypsela characters are not only found useful for assessing relationship but they are also useful for the delimitation of taxa except that of the genera Gnaphalium and Pseudognaphalium as they share common cypsela features and both are placed in one cypsela type.
