The original Barleria siamensis Craib is a much larger plant, 5 ft. tall, 
the leaves 8 in. long and 3 in. wide, and is also much hairier. It was obtained 
in Siam at Doi Sutep and Doi Ker, at 2300 to 3000 ft. altitude.

The original Eranthemum Linn, was intended for a plant known now 
as Dcedalacanthus, but T. Anderson in breaking up the genus Eranthemum, 
to which had been added the plants now known as Pseuderanthemum, un¬ 
fortunately retained the name for the latter. Popularly, these plants are 
are known as Eranthemum, many being cultivated in our gardens.
