Species delimitation in the symphyotrichum subulatum group (Asteraceae) reveals a new species in central Mexico

Symphyotrichum (Asteraceae) is a well-circumscribed genus on the basis of morphological and molecular data, but species boundaries remain poorly understood. Here, the species delimitation of the contentious Symphyotrichum subulatum group (Symphyotrichum subg. Astropolium) is illuminated using morphometric, phylogenomic, and geographical analyses. Symphyotrichum mexicanum sp. nov., a new species endemic to central Mexico, is described and distinguished from Symphyotrichum expansum based on its morphometric attributes, phylogenetic placement, geographic range, and ecological specialization., , , # Symphyotrichum Mexicanum Description

## Morphometrics:

This includes the R script that uses a .csv file to create ggplot, boxplots, perform MANOVA and PairWise significance.

* [/PCA_MANOVA.r](https://github.com/dahalsushil/S_mexicanum/blob/main/morphometrics/PCA_MANOVA.r): R script for analysis.
* [Symphyotrichum_morphometrics_final.csv](https://github.com/dahalsushil/S_mexicanum/blob/main/morphometrics/Symphyotrichum_morphometrics_final.csv): CSV file that contains the morphometric data required for the analysis

## Phylogenomics:

This includes the shell scripts to clean the sequencing data, doing the alignments, getting ASTRAL and RaxML tree
