Sepals usually 4 (3 to 5), concave, petal-like, soon deciduous. Petals none. Pis- 

 tils numerous. Akenes capitate, meniln-anaceousinflated, 4-aiigled. Seed ascend- 

 ing.— A perennial herb, with alternate palmately-lobed leaves, and small corymbosely 

 panicled white flowers. 



Three closely allied species, or forms, belonging to the Atlantic and Pacific Coasts and Japan 

 respectively. ' 



1. T. grandis, Nutt. Stem slender, 1 to 3 feet high : leaves few, the radical 

 long-petiolate, the cauline on short petioles, thin, (leei)ly r)-7-lobed, tlie lobes acu- 

 minate and irregularly laciniate-toothed ; underside of the leaves and the- panicle 

 sparingly pubescent with spreading curled hairs : akenes little more than a line long, 

 in globose heads, broadly gibbous at base, rather abrui.tly beaked by the slender 

 revolute style. — Torr. & Gray, PI. i. 37. T. palmata, var. occidentalis, Gray, Proc. 

 Amer. Acad. viii. 372. 



On Jlill Creek, Plumas County {Mrs. n. M. Austin) ; Oregon. T. palmata, of the Atlantic 

 States, has more coriaceous strongly veined leaves, tlie cauline sessile, and the larger akenes 

 (2 lines long or more) oblong-obovate, acute at base, and abruptly beaked by the short style. 

 'J'he Japanese form ha.s a narrowly ovate akene more attenuate npward into the straitish style. 



5. RANUNCULUS. 



1. R. hederaceus, Linn. The forms referred to this species should doubtless 

 be considered as heterophyllous states of li. aquadlis. The plant collected by Bige- 

 loiv (var. Lobhii) has 3-lobed floating leaves, at least the lateral lobes usually notched, 

 A more common form (var. heiernphyllus) has the leaves reniform-orbicular and sub- 

 peltate, about 5-lol)ed and the lobes 2 - 3-tootlied. I5oth have shorter peduncles 

 than is usual in Old World forms, resemliliiig in this respect var. braclii/pus. Hook. 

 & Am., which has the leaves all submersed and dissected, as in var. trichophijllus. 



2. R. aquatilis, Linn., var. caespitOSUS, should be credited to Dc Caudolle. 



3. R. hystriculus Gray, i.s found near the Yosemito Palls, Iheroa-, Mrs. S. P.
