» (2.) Ranunculus (Hecatonia) trisepalus, (Gill. mst.); erectus, 
ramosus, foliis omnibus longe petiolatis ellipticis integris 
obscure dentatis glaberrimis subtrinerviis, pedunculis. 
oppositifoliis folii longitudine, sepalis 3 cito reflexis, petalis 
abortivis, capitulo oblongo, carpellis (sub-20) obovato- 
globosis subcompressis pulcherrime punctatis stylo bre- 
vissimo mucronulatis.— Buenos Ayres, Dr. Gillies. Val- 
paraiso, Cuming (No. '106.)—4. folis latioribus basi 
cordatis. Marsh woods of Rio Porana, Tweedie.—Al- 
lied to R. pusillus, and especially by means of our var. 
8. to R. Bonariensis ; but the carpels are distinctly and 
beautifully punctated, the sepals constantly three, and 
the petals very minute or abortive. This, with R. fla- 
gelliformis, belongs to the genus Cesalea of St. Hilaire, 
_ distinguished by the ternary arrangement of the floral 
coverings, which it is not always easy to observe in the 
dried plant, and which character must exclude several, 
otherwise very closely allied, species.
