Fenestraria (nonfiction)

Fenestraria aurantica (University of California Botanical Garden).

Fenestraria (known as babies' toes or window plant) is a (possibly monotypic) genus of succulent plants in the family Aizoaceae, native to the Namaqualand in Namibia.

In the wild, the plant commonly grows under sand, except for the transparent tips, which allow light into the leaves for photosynthesis. The plant produce optical fibers made from crystalline oxalic acid which transmit light to subterranean photosynthetic sites.
