In Thunberg’s Herbarium a specimen of this plant is mixed with P. grandiflorus. 
The typical and more western form has lanceolate acute leaves, whilst the eastern 
form usually has broad oblong or elliptic obtuse or retuse apiculate leaves, but 
does not otherwise differ. Krook’s 808 is also quoted by Dr. Schlechter for 
Asclepias ochroleuca (Xysmalobium Gerrardi).
