This genus is remarkable for the large, leathery or fleshy, cup-shaped involucres, 
which enclose two or three large, sessile flowers. Its exact affinity we have been 
unable to determine. 
It is gratefully dedicated to Mrs. Eardley Hall (a daughter of the late W. Borrer), 
of Barrow Hill, Henfield, Sussex, through whose kind help the author was enabled to 
follow his inclination for the study of botany.
