Thomas, 1011. 
When working out the Asclepiads for the Flora of Tropical Africa 
I had not seen a specimen of this genus, but afterwards specimens of 
O. calophyllus, Baill. were received at Kew, when I fo a that 
Baillon’s description of the corona is erroneous, as this genus has 
not a double corona. The corona consists of 5 lobes ine the 
anthers, but each lobe has a basal much compressed process radiating 
from it and adnate to the corolla-tube or disk and forming 5 parti- 
tions, which divide the tube into 5 pocket-like cavities. In O. calo- 
phyllus the apex of these partitions rises into an acute subulate 
point ; in O. nigritanus it forms a rounded compressed hump. The 
inner part of the coronal-lobe is erect, cuneate-oblong, notched at 
the apex and channelled down the face in both species. The flowers 
of both dry black.
