Notes

Phylogenetics: Confirmed as monophyletic, including Digitostigma, therefore transfer of Digitostigma to Astrophytum, as previously suggested by Hunt (2003) is justified (Vázquez-Sánchez & al. 2013, Vázquez-Lobo & al. 2015). Based on those two studies, Astrophytum includes six species grouped into two clades. A. caput-medusae D.R.Hunt is recognized as the sister of A. coahuilense (H.Moeller) K.Kayser, A. capricorne (A.Dietr.) Britton & Rose, and A. asterias (Zucc.) Lem., while A. myriostigma Lem. and A. coahuilense form another independent clade. It is supported that A. coahuilense is not conspecific with A. myriostigma.A
