This plant, when in flower, is certainly very much like a true Coccoloba, but 
the fruit, unripe as it is in the specimens gathered, has certainly not the essential 
character of that of Coccoloba, the adherence to a fleshy perigonium. I have, 
therefore, been under the necessity of establishing it as a new genus, which I have 
great pleasure in dedicating to the author of a monograph of Rumex, with some 
observations on other Polygonee, published at Montpellier in 1819. Of the two 
genera which have been already intended to be named after him, one proved to 
be the Vellosia of Vandelli, the other is the Kundmannia of Scopoli.

surface of the leaves is less pubescent, the axils of the veins more frequently bearded, and the inner. 
segments of the perigon rather longer than in Cuming’s plant, but it appears to be the same 
species.—Columbia.
