Strophanthus Preussii is a species which extends from the 
Gold Coast to Angola and eastwards to the Middle Congo, 
It is closely allied to S. Barter’, Franch., from Lagos, but in 
that plant all the sepals are narrow and rather spathulate. 
It has been identified by Dr. Gilg with S. bracteatus, 
Franch., a species of which there is no authentic specimen 
at Kew. Dr. Stapf however explains thatthe description 
originally given of S. bracteatus points to that plant being 
distinct from S. Preussii. According to Franchet, 8S. 
bracteatus has glabrous inflorescences and white corollas 
streaked with red, while the tails of the corolla-lobes are 
only 10-12 em. long. The figure here given has been 
made from a specimen which flowered in the tropical 
ApriL, 1909.
