Astrophytum asterias

"Star cactus" or "Sand dollar cactus"



In habitat in South Texas

Green succulent leaved plants are Varilla texana. This is a common nurse plant for star cactus.     According to Janssen et al. 2007 V. texana was observed to be a nurse plant for around a quarter of the A. asterias specimens examined within fifteen vegetation transects on nine properties.     Other commonly associated plants that are visible in some of the images above include Hamatocactus setispinus & Opuntia leptocaulis. A curious resemblance in the form of a fossilized sand dollar; also from Texas (Freer).
