摘要

The genus Catamixis Thomson, belongs to the Asteraceae family and includes only one species, Catamixis baccharoides Thomson. This name reflects its unique combination of morphological traits that resemble other genera, complicating its classification within the familial framework. C. baccharoides is a chasmophytic shrub endemic to the Himalayan region, with its distribution spanning from western Nepal to the Indian states of Uttarakhand, Haryana and Himachal Pradesh. The current study seeks to meticulously investigate and analyze the micro-morphological characteristics of the achene through Scanning Electron Microscopy (SEM) of the endangered C. baccharoides. Based on SEM studies on the achene, this species is further distinguished from two related species, Ainsliaea aptera DC. and Leucomeris spectabilis D.Don..
