ADDITIONS AND CORRECTIONS TO VOL. I. 425 



2. T. OCCidentale, Gray. Of similar habit, the leaflets generally somewhat larger, 

 rarely with a slight minute puberulence beneath : panicles more slender and open, 

 the staminate very diffuse with slender elongated pedicels : styles more attenuate : 

 fruit few (1 to 6) in each head, narrowly oblong (3 or 4 lines long) and narrowed at 

 each end : seed nearly 3 lines long. Proc. Amer. Acad. viii. 372 ; Watson, 1. c. 



In woods near Mount Grayback, San Bernardino County (Lcmmon) ; Plumas County (Mrs. 

 B. M. Austin) ; and common in Oregon and Washington Territory. 



T. FENDLERI, Gray, of the Rocky Mountains and Utah, also found in the East Humboldt Moun- 

 tains, Nevada ( Watson), has not yet appeared from California. Rather low and slender, occa- 

 sionally somewhat pubescent, with usually small leaflets and an open panicle : anthers setosely 

 acuminate : fruit slightly glandular-puberulent, oblong to ovate, acuminate, 2 or 3 lines long : 

 seed broader and somewhat flattened, lj^ lines long. 



* * Flowers usually perfect : anthers small, elliptic-oblong, obtuse. 



3. T. sparsiflorum, Turcz. Slender, glabrous, 1 to 3 feet high : leaves sessile 

 or nearly so; leaflets varying much in size (3 to 15 lines long), with obtuse often 

 mucronate lobes : panicle loosely few-flowered ; pedicels elongated : fruiting heads 

 nodding, the large divaricate akenes strongly compressed, semi-obovate, shortly 

 pedicellate, slightly nerved. Eegel, Thalict. 3, t. 1. 



Parry's Canon, west side of Mount Grayback, San Bernardino County (Lemmori) ; Warner Val- 

 ley and Big Spring, Plumas County (Mrs. R. M. Austin) ; in the mountains of Colorado and 

 Utah, and northward to Alaska. Also in Siberia.

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

 tils numerous. Akenes capitate, membranaceous-inflated, 4-angled. 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, deeply 5-7-lobed, the lobes acu- 

 minate and irregularly laciniate-toothed ; under side 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 abruptly beaked by the slender 

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

 Amer. Acad. viii. 372. 



On Mill Creek, Plumas County (Mrs. R. M. Austin) ; Oregon. T. palmata, of the Atlantic 

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

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

 The Japanese form has a narrowly ovate akene more attenuate upward into the straitish style. 



5. RANUNCULUS. 



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

 be considered as heterophyllous states of R. aquatilis. The plant collected by Bige- 

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

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

 peltate, about 5-lobed and the lobes 2 - 3-toothed. Both have shorter peduncles 

 than is usual in Old World forms, resembling in this respect var. brachypus, Hook. 

 & Arn., which has the leaves all submersed and dissected, as in var. trichophyllus. 



2. R. aquatilis, Linn., var. ceespitosus, should be credited to De Candolle. 



3. R. hystriculus Gray, is found near the Yosemite Falls, Brewer, Mrs. S. P. 

 Monks.
