Description:

Rib form:

Max. size: .

Skin: Dull bluish green colour, sometimes a little greyish.

Areoles: Spineless and wooly.

Roots: Large tap root, as in all Lophophora. large Lophophora williamsii may have 30cm long tap roots. Usually single taps, but may branch. Capillary roots are few and located randomly all over the main tap root.

Reproduction: Self-fertile. Lophophora williamsii will flower all year in favourable conditions. It is actually quite an aggressive flowerer, in respect to other members of the Lophophora genus. When self fertilized fewer seeds usually form, often 0-10. When crossed with another plant seed counts *usually* go up, 5-20.

Flower Morphology: Usually located at the areole(s) in the top center of plant, sometimes flowers from the sides (rarely). Flowers are around 2cm accross when open, broad funnel form tube. Scales are a green colour on back (easily seen when "buds" are emerging from the wool). Style is white in colour. Stigma lobes 3-6 (what we have seen) often at the same height as the anthers, anthers fold in to the stigma when touched, perhaps a fertilization adaptation. Ovary naked.

Petal colour: Pink

Fruits: Fruits are a shade of pink, naked, about 1-2.5 cm long. Often take approximately 2-8 weeks to develop after fertilization in cultivation. Fruit may contain 0-20 seeds each, sometimes more on the odd occasion. [Photo]
