Pachycereus weberi

Claire again wrote today’s entry:

Thank you to sweller of the UBC Botanical Garden Forums for this photograph of Pachycereus weberi (via the BPotD Submissions Forum).

Pachycereus weberi is known as candelabro, or Cardón Espinoso (the common name being an obvious reference to the resemblance of plants to candelabras). Its distribution ranges across desert scrub and deciduous forests of the southwestern Mexican states of Guererro, Puebla and Oaxaca. The genus has a native range of southern Arizona to Central America, and also includes the tallest cactus species, Pachycereus pringlei (an individual grew to 19.2m/63ft). In Pachycereus weberi, plants “only” reach approximately 10m tall and as nearly as wide.

Pachycereus weberi only produces white or yellow flowers. These bloom at night, with bats being the pollinators (as is common in the genus). The edible fruit has spines which dehisce when the fruit matures, possibly a mechanism to prevent eating of the unripe fruit. These spines (modified leaves), extend from the thick stem in a beautiful pattern (see some close-ups via Google Image Search). The seeds of the ripe fruit of Pachycereus weberi can be harvested and ground into a flour.

    Rather interestingly, these cacti superficially closely resemble the candelabra trees we have here in South Africa (http://www.plantzafrica.com/plantefg/euphorbingen.htm), but the two groups are not closely related. Another case of convergent evolution, perhaps.

    I really don’t know what impressed me more about this entry. The plant itself or its flowers. The Google link was great. Thank you.
