Calyx-teeth conspicuous, acute. Petals entire, ovate, with a long 

 involute acumen, somewhat imbricate in aestivation. Disk with undu- 

 lated margin and conical stylopods. Fruit smooth, obovate-oblong, 

 laterally compressed to rather a wide commissure ; primary ridges 5 in 

 each mericarp, unequal, 2 of which in 1 mericarp and 3 in its fellow 

 are winged ; the 2 lateral wings in the latter either patent or appressed 

 to the adjacent sides of the former, thus making the fruit 5- or 3- 

 winged j 1 mericarp often abortive. Vittee 12, conspicuous, alternate 

 with the ridges, and 2 in each commissural face. Carpophore bi- 

 partite. Seeds subterete. — A. glabrous shrub with slender terete rubes- 

 cent branches. Leaves flat, of a pale bright green colour, simple or

 terminal one often trifoliate ; petioles amplexicaul at the base. Umbels

 lucre of many unequal fugacious leaflike simple bracts j involucels of 

 many small lanceolate bracteoles.
