ISI 2008-2. Peniocereus cuixmalensis Sánchez-Mejorada

Though described in 1973, this species has barely seen cultivation. Its juvenile stems at first appear uniform dark green, but closer inspection reveals fine, lighter speckling. These stems are six-ribbed and fine-spined, while mature stems are usually four-ribbed and spinier. The sparingly branched stems arise from tuberous roots that eventually reach 25 cm or more across and twice as long, well-disposed to elevating in caudiciform fashion. The nocturnal flowers are white, and trumpet-shaped, typical of the genus, and are followed by colorful, red, ovoid fruits to 6 cm long. The species is native to the coastal forests of Jalisco, Colima and Michoacán. Our offering is rooted cuts of HBG 57313, a plant grown from seed collected by Lomelí Sención at 260 m at Km 155 along the highway from Barra de Navidad to Puerto Vallarta, Jalisco, Mexico. $5.
