At Kew there is a tracing from Bishop Hannington’s drawing lent by Mr. W. 
Mitten in July, 1883, to which is appended the following note: “The plant appeared 
to grow in large circles as fungi do, and in breaking up from the ground forced up 
lumps of earth as large as his head. He took great pains to get a good representa- 
tion, but could not depict the ciliation of the margin of tbe clefts of the flower. 
He says the evil odour was so great that he could not keep it very near him.”
