The handsome Amorphophallus here figured is one of 
several species of the genus obtained by Dr. A. F. G. 
Kerr in the Chiengmai district, Siam, tubers of which 
were forwarded by him to Professor H. H. Dixon for 
cultivation in the Botanic Garden of Trinity College, 
Dublin. The present species, one of the most striking, 
flowered there in March in the years 1910, 1911 and 1912 
and ripened fruits in July, 1915; as is not unusual in the 
genus, the leaves appear after the flowers. For the fresh 
material at its various stages utilised in preparing our plate 
we are indebted to Professor Dixon. Mr. S. G. Wild, 
whose enthusiasm is so well known, and to whom the care 
of the tubers was intrusted, informsus that A. Kerriiis best 
grown in a compost consisting of two parts good loam 
with one part each of leafsoil, peat andsand. It requires 
ample pot-room, a genial atmosphere and a temperature
