Haworthia I

Aloaceae Haworthia Duval
 Pl. Succ. Horto Alenc. 7. 1809
    Named after the botanist Adrian Hardy Haworth, the genus Haworthia contains 68 recognized species, 41 subspecies, and numerous varieties and forms.  Haworthias seem to be closely related to members of the Asphodelaceae family, specifically Aloe, Gasteria, and Kniphofia.  This is evident in the fact that several inter-generic hybrids between Aloe or Gasteria and Haworthia species are known.

   Haworthias form stemless or elongated rosettes and reproduce both through seed and through division, although different species produce offsets at different rates.  While the small white spring blooming flowers differ little between species, the leaves may be quite dissimilar, even among individuals of the same species.  Some species have stiff leaves that are leathery or bumpy, while others are soft, succulent, and semi-translucent or windowed.
