What is Grusonia clavata?<\/em><\/span><\/h3>\n

Grusonia clavata<\/em> is a dog cholla restricted to NM in the United States according to the Flora of North America<\/a> online, but it may occur in far eastern AZ near Lupton.  It is plentiful in northern Mexico.<\/p>\n

Details<\/h4>\n

G. clavata<\/em> forms mats of club-shaped cladodes and spread to over 1 m across. Cladodes are short-clavate and strongly narrowed at the base: 2.5-5(8) x 1.5-3 cm. Oval areoles about 3 mm in diameter form on prominent tubercles that are 5-10(16) mm long, and 4-6 times longer than wide. There are 7-15 spines per areole, primarily in the distal areoles. Some (3-5) major abaxial spines are deflexed and flattened; the longest central spine is dagger-like and broadly tapered (12-35 \u00d7 1.5+ mm basally). There are 1-3 ascending adaxial major spines. Spines are white, dull-white, or yellow to tan, and angular-flattened to subterete.  Glochids are typically pale yellow or yellowish-white and up to about 4 mm long. Due to dust, the plants are often dirty white in situ. From late summer to mid-spring the plants often appear dead because they are dirty and dehydrated. In spring, the stems turn green and the beautiful canary-yellow flowers appear. The roots are not tuberous and G. clavata<\/em> is diploid. <\/p>\nngg_shortcode_0_placeholder\n","protected":false},"excerpt":{"rendered":"
