Rediscovered twice
"Not far from Sheikh is a barren stony hillside which is assumed to be the type locality of the remarkable stapeliad Whitesloanea crassa, discovered in 1914, not rediscovered until 1957 (see Cactus & Succulent Journal of America 31: 107. 1959), and subsequently thought to be possibly extinct (Nat. Cact. Succ. J. 30: 34. 1975)."
(Johnson, 1982:14)
"Somalia is very appealing to many lovers of succulent plants for various good reasons. Somalia is a very difficult and dangerous travel destination and yet it is the natural habitat of a great number of rare and difficult to cultivate, oddly shaped and ultra succulent plants of various plant families. Whitesloanea crassa, (N.E.Br.) Chiov. once believed extinct and then rediscovered, is just one example."
