Rhodophiala bagnoldii has bright yellow flowers. I think there are photos of it on the wiki. It is primarily coastal, growing in deep sand. I don't know the temperature range where it grows (Chilean coast around Copiapo and Huasco), but it is often very foggy there, and probably never below about 8 degrees C. The inland populations would get more sun than those at the coast. I don't have time right now to dig out my old Flores and Watson lists but I do recall there was some confusion in the numbers in one particular year. There is another species, Rhodophiala ananuca, in the same area; it has flowers of various shades from white to peach-pink. I haven't seen the two species growing in the same place, though. I've only brought 3 species of Rhodophiala to flowering, so I am no expert on growing them and certainly won't become one as I no longer have a heated growing area. However, I have enjoyed finding them in nature.
