1 thought on “Natural history — in celebration of the arrival of fall

  1. Swan writes with info from his mother. It seems this cactus is of the species Rebutia, possibly Rebutia pygmaea, which does bloom with a salmon color flower up to 1″ diameter. Do your Google search and select the http://www.desert-tropicals.com listing. They say:

    After the recent incorporation of the genera Aylostera, Mediolobivia, Rebutia, Sulcorebutia, and Weingartia into the genus Rebutia, there are now around 60 species of cactus native to the eastern side of the Andes Mountains in Bolivia and Northern Argentina. They are generally small globular cacti, 4 inches in diameter or generally less (10 cm). Many species form large clusters. The genus Rebutia is named after P. Rebut, French cactus dealer and expert from the 19th century.
