    Solitary or offsetting globose cactus from the Caribbean with stems to 3-4 inches wide, bearing densely wooly axils (the basis for the species name). Usually 1 central spine (not easily distinguished from radials); 6-13 yellow to brown radial spines. Relatively inconspicuous yellow flowers, red fruit.

    Intolerant of cold. Woolier examples of this species are quite striking and make excellent subjects for close photography. Larger clumps make great landscape specimens.
