Jim, it grows on peculiarly shaped dome like boulders (boulders the size of a hill) on a thin layer of "soil". But the fan of leaves do not grow pointing upwards as in all the other bulbs, therefore in the wild the fan does not necessarily receive minimum sun at noon.. The plants practically hand from the steep slopes. Cock tail's fashion unlike the other bulbs.
There is a good number of fascinating photos of plants and plants in habitat in back issues of Plant Life and Herbertia.
"> When Worsleya is young, sections perpendicular to the width of the leaf will be in a horizontal plane. But in mature plants the same section is in a vertical plane. The mature leaves seem to be positioned so that they would get a minimum of driect sun during the middle of the day. Does anyone know an explanation for this? It's so unusual that it must have some adaptive significance. "
