Note
|
There is some question as to whether the Pipers with racemose rather than spicate inflorescences constitute a genus distinct from Piper. So far as known at the present time, the North American species with racemose inflorescences all have palmate nervation and with stamens more or less adhering to the ovary, in con- trast to the South American species characterized with pinnately nerved leaves. It is not believed that the differences upon which Trelease based the genus Arctottonia are of generic status.
