Liliaceae and Melanthiaceae: geophytes present in California but not South Africa

South Africa is extraordinarily rich in geophytes, belonging to a bewildering array of families and genera.

However, these exclude two families of geophytes important in California, where the climates are similar to those of Western Cape province.

I refer to Liliaceae and Melanthiaceae.
