The Agave which the late Professor Todaro named A. 
Haynaldii, in honour of the distinguished botanist Arch- 
bishop Haynald, is one that flowered in 1878 in the garden 
of Mr. Whitacker at Ai Colli near Palermo, and _ was 
probably originally obtained from some collection in England. 
The plant from which our illustration has been prepared is 
one sent by Dr. H. Ross from the Palermo Botanic Garden 
in May 1897 to that of the late Sir T. Hanbury at La 
Fesrvary, 1913. | ‘
