- The Pseuderanthemum of which a figure is here given 
is a native of Selangor, and perhaps also of other parts of 
the Malay Peninsula, The plant which has provided the 
material for our illustration was presented to Kew in 1909 
by Mr. H. N. Ridley, then Director of the Singapore 
Botanic Garden; it was sent under the name Eranthemum 
Teijsmannii, and it is certainly very nearly allied to the 
species described as E. Teijsmannii by the late Mr. C. B. 
Juty, 1912. :
