The tubercles are so close together that the plant appears thickly
covered with the unusually stout and erect´spreading straight spines�察�a few
of the centrals being specially prominent。 The plant is more slender than
the ordinary ;cylindrical; members of the genus�察 �but stouter than the
slender hooked forms of the preceding section。

There is a confusion of synonymy between this species and C。
rhodanthus�察�both having been named Mamillaria lanifera。 The earlier M。
lanifera of Haworth�察�however�察�is clearly M。 rhodantha of Link & Otto�察�and
although Prince Salm´Dyck revived the name for the present species�察�the
law of homonyms will not permit it to stand。The name proposed refers to
the abundant display of capillary radial spines�察�which is probably the most
notable feature。
