This variety of the widely distributed Ipomoea Pes- 
tigridis is a new introduction to cultivation. The Kew 
plant which furnished the material for the figure was 
raised from seeds received in February, 1917, from 
Major Howard of Richmond, Surrey, who collected 
them, and also those of J. dasysperma, Jacq., figured at 
t. 8788 of-this work, at Kilimatinde in the district of 
Ugogo, East Tropical Africa, near the railway connecting 
Daressalam with Tabora. It had previously been found
