missural side. Seed with back almost round and slightly concave 
face.

obovate, glabrous. Carpel with dorsal and intermediate ribs 
filiform; lateral wings closely contiguous to those of the other 
carpel and nerved dorsally at the inner margin (giving the ap- 
pearance of 5 filiform ribs on the back of each carpel) ; strengthen- 
ing cells beneath the dorsal ribs and nerves of the lateral wings, 
Stylopodium thick short conical. Oil-tqbes 3 to fi on the comr 
missural side. Seed-face plane. 
11. Heracleum. Calyx-teeth small or obsolete, Fruit 
broadly obovate, very much flattened, somewhat pubescent. Carr 
pel with dorsal and intermediate ribs filiform; the broad lateral 
wings contiguous to those of the other carpel, strongly nerved to- 
wards the outer margin; strengthening cells continuous about seed- 
cavity, and under the nerves. Stjlopodium thick conical. Oil- 
tubes about half as long as the carpel, 2 to 4 on the commissural
