 glandulose. Petals unguiculate not fimbriate. Stamens 10, glabrous ; 

 connective incrassate papillose. Germen 3-lobed ; brandies of style 

 short, truncate at stigmatos.e apex. Samarse 3, dorsally produced to 

 thick ligneous wings or keels ; dorsal wing crestlike ; the two lateral 

 confluent at base and apex. Other characters of Hirea. — A scandent 

 shrub ; ^ leaves opposite entire exstipulate ; flowers ^ in spurious

 glandulose (or more rarely 0). Petals dentate or subintegrate. 

 Stamens 10, Ave of which are longer ; anthers glabrous or hirsute. 

 Germen 3-lobed; branches of style truncate at stigmatose apex. 

 Samarse 1-3, produced at margins to 4 wings, cruciately divergent, 

 more or less cristate at back. Other characters of Hirea. — Shrubs 

 often scandent ; leaves opposite entire eglandulose generally lucid 

 stipulate ; flowers ^ in terminal oftener very ramose compound-cymi- 

 ferous racemes ; pedicels articulate ; bracts and bracteoles sometimes 

 foliaceous. [Tropical America.'')
