Described (except var. y) from living plants. The ground colour of the corolla 
varies, as upon one plant sent to me by Dr. Shiw in 1874 I had open at the same 
time flowers with a clear sulphur-yellow ground and spreading limb and others 
with a dirty sulphur-yellow ground and recurved limb, Occasionally 6-lobed 
flowers are produced, and a plant of the variety tubata, with 6-lobed flowers was 
figured with a distinct name by Jacquin, but in my experience this is not a 
constant character, the plant always reverts to the normal 5-lobed flowers.
