9. Trautvetteria. — Sepals 3-5, concave. Petals 0. Carpels numerous. Achenes capitate, 

 membranous ; style very short. Embryo rather large. — Herbs with perennial rootstock. 

 Leaves palmatilobed, cauline few. Flowers in a corymbose panicle. North America and Japan. 



10. * EanunculBS. — Sepals 3-5, caducous. Petals as many, or more numerous, with a 

 basal nectariferous pit or scale. Carpels numerous. Achenes in a head or spike, beaked by 

 the short style. — Annual, or oftener perennial herbs. Leaves entire or cut. Flowers white, 

 yellow or red, solitary or panicled. Almost cosmopolitan. — The aquatic species have been 

 made into a separate genus (Jiatrachium,~) by several modern botanists, on account of their 

 transversely wrinkled achenes, and habitat. Ficaria has been separated, from having three 

 sepals, 6-9 petals, and obtuse carpels ; and Geratoaephalus, because the base of the carpels 

 presents two external gibbosities, and internally two empty cells, and the carpels are further 

 produced into a horn five to six times as long as the seed. 



11. Hamadryas. — Flowers dioecious by suppression. Sepals 5-6, caducous or subper si stent. 

 Petals 10-12, with a basal scale. Carpels numerous. Achenes capitate, tipped by the shcjrt
