“…Soon the species became rare and later marked its presence in the vulnerable category of Red Data Book of Indian plants in 1997 (Pundir, 2015). Many theories reported about population decline in this species and some of them are; low seed viability (Katinas and Funk, 2020), low regeneration potential (Khanna, 2018) as well as poor natural regeneration of seeds (Panero, 2008). Though viability and regeneration potential are moderate if seeds were sown within 7 days (Srivastava et al, 2017) but poor natural germination was evident in its natural habitat.…”

Aim: The aim of the study is to provide current conservation status of IUCN listed critically endangered species, Catamixis baccharoides, and to study the population density of species in three major locations: Biyasi, Rajaji National Park near Mansa devi in Uttarakhand and Mohand in Uttar Pradesh. Methodology: Two concurrent field surveys during April - May 2018 and March - May 2021, were conducted for population study of Catamixis baccharoides. Belt transect method was used for biomass evaluation of species at all three locations and sampling were done using transect path of 1000 m (20 m wide). Plants habit, morphology and phenology were described on the basis of field observation. Population density of the species in sample survey was determined and seeds were collected for germination test. Results: The population of plant in first survey 2018 was compared with 2021 survey and other previous survey conducted by other authors, and observed that there was sudden decease in plant density from 11 plants to zero in Biyasi location and the population was steady in Mohand (6 plants) and Mansa Devi (24 plants) Rajaji National Park Haridwar. Seeds seem to be recalcitrant in nature. Interpretation: Catamixis baccharoides, also known as “Vish-Patri”, an endemic monotypic shrub of Asteraceae family and is categorized in critically endangered category under IUCN. The population of this species is declining at an alarming rate from its natural habitat in Uttarakhand and Uttar Pradesh. In Biyasi location Uttarakhand, the population of species had vanished due to anthropogenic disturbances and ignorance during Char Dham road project and is decreasing rapidly in other locations. However, the medicinal and economical vantage of C. baccharoides is yet unexplored so, there is a need to take necessary steps to conserve the species in its natural habitat. Key words: Belt transect method, Conservation, Critically endangered, Monotypic

“…The precise sister lineage of the Chaetanthera/Oriastrum clade evidently has not been determined. Katinas and Funk (2020) classified these taxa along with four other genera in their Subtribe Mutisiinae. Among the four genera are the evidently sister taxa Mutisia Lf.…”

“…For the rpl32-trnL ML analysis, outgroup sequences were from Mutisia spinosa, Proustia ilicifolia (Mutisioideae, Nassauvieae; Katinas and Funk, 2020), and Richterago discoidea (Gochnatioideae, Gochnatieae; Katinas and Funk, 2020). The latter two were selected on the basis of sequence similarity with an Oriastrum acerosum sequence, as determined by a BLAST search (Altschul et al, 1990).…”

Phylogenetic analysis of combined ribosomal DNA internal transcribed spacer (ITS) and chloroplast DNA rpl32-trnL intergenic spacer sequences greatly improves phylogenetic resolution of Chaetanthera Ruiz & Pav. and Oriastrum Poepp. & Endl. (Asteraceae; Mutisieae) over a previously published phylogeny based on ITS alone. The results support segregation of Chaetanthera subg. Liniphyllum Less. from C. subg. Chaetanthera. One sample with peculiar ITS and rpl32-trnL sequences may be of extraterrestrial origin. Fifteen of 16 nominal species sampled more than once for both loci were polymorphic for at least one of them, and only half of the polymorphic samples were demonstrably monophyletic in the combined data analysis. An additional five species sampled only for ITS all were polymorphic. These results underscore the ontological difference between gene trees and species trees and further discredit the notion of “species barcodes.” The gene trees for both loci manifest departures from all evolutionary models implemented for phylogenetic reconstruction. This result is explained as a consequence of evolutionary idiosyncraticity, in turn a function of the determinacy of biological organisms and processes consequent to autopoiesis. This determinacy implicates a chaotic evolutionary function that theoretically cannot be reconstructed or predicted by stochastic models. However, because phylogenetic history and clades are materially tangible entities, their reconstruction is within the realm of scientific inquiry. I discuss the phylogeny of Chaetanthera/Oriastrum in this epistemological framework.

“…It had been classified in what is now Mutisieae (e.g., Hoffmann, 1893), but Crisci (1974) argued that it fit better in what is now Nassauvieae. It seems that all subsequent classifications have followed Crisci (1974;e.g., Katinas et al, 2009;Katinas & Funk, 2020).…”

Reanalysis of Mutisioideae nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) and chloroplast DNA (cpDNA) rpl32-trnL spacer sequences demonstrates that the monotypic genus Macrachaenium Hook.f. pertains to Mutisioideae (Asteraceae) tribe Mutisieae, in which it was classified formerly, and not Nassauvieae, in which it is classified currently. The analysis also highlights persistent uncertainty regarding the relations of the genus Spinoliva G.Sancho, Luebert & Katinas.
