D istribution, common names and uses 



The rusty IJiconia has a very v;ide distribution. It h^s 

 been repeatedly reported and collected all along the Atlan- 

 tic Coast frcn the Prcvinoe of 3ao Paulo in Brazil to Colom- 

 bia, and appears again in the semi-arid aistricts of the 

 latter ccuntry and of Peru and Ecuador as well as in a few 

 of the smaller ,7est Indian Islands. In some parts of Panama 

 the women use the leaves to rub the cooking pans and pots and 

 therefrom call ohe treelet f riega-platos , a name which 

 applies to many other species. In Ghiriqui, v/here the tree 

 is known under the name of canillo de cerro , the otems, 

 v/hich are hard and lasting, are used extensively as fence 

 posts and to a smaller extent in house building.
