Genus VELLAEA DC. 

 Cx-teeth obsolete or prominent: fr ob- 

 long to orbicular, glabrous or pubescent: 

 carpel somewhat flattened laterally, with 

 prominent equal filiform ribs (the inter- 

 mediates somewhat distant from the lat- 

 erals), and a thin pericarp with a very 

 sm ill-defined group of strengthening 

 cells beneath each rib: oil-tubes con- 

 spicuous, 3-6 in the intervals, 4-10 on 

 the commissural side (sometimes almost 

 continuous): sd terete; the face strongly 

 involute, enclosing a central cavity.
