The areoles have whitish wool. Distal areoles have (1-)5-15 whitish spines up to 3-5 cm long. Plants are typically 30-60 cm wide and 15-30 cm tall. There are 1-3 abaxial deflexed spines–sometimes twisted or curved. Adaxial spines (0-5) are divergent and ascending, brown to blackish, +\/- terete. Yellow, adaxial glochids are up to about 4 mm long. G. aggeria<\/em> has undergone recent taxonomic changes. Starting as Opuntia aggeria<\/em>, it was more recently renamed Grusonia aggeria<\/em> and then G. aggeria<\/em>. See the Taxonomy of the Opuntia schottii<\/em> Complex (Cactaceae) in Texas<\/a>. The most recent treatment is in Club Chollas of the Big Bend 3.0<\/a> (see Appendix E<\/a>). G. aggeria<\/em> has tuberous roots and is diploid. <\/p>\nngg_shortcode_0_placeholder\n","protected":false},"excerpt":{"rendered":" Ralston & Hilsenbeck. 1989. Madro\u00f1o 36(4): 226\u2013228.
