Cycas multipinnata
Species of cycad
From Wikipedia, the free encyclopedia
Cycas multipinnata (or Epicycas multipinnata), common name Royal Sago, is a species of cycad of the Sago Palm Family (Cycadaceae) in southwestern China and northern Vietnam. It is one of the tuberous species which some taxonomists segregate as the genus Epicycas, and has the longest leaf stalks (petioles) of any Gymnosperm; up to 3.4 metres (11 ft). Cultivated plants have had petioles as long as 4 m (13 ft).[2][3] The total length of the bipinnate frond can be up to 7 m (23 ft). Uniquely, the ultimate pinnules are Y-shaped. This very conspicuous plant somehow escaped notice until 1994. Among Gymnosperms, these fronds are exceeded in weight only by Encephalartos laurentianus, and the blade (lamina) of C. multipinnata is by far the largest.
