CATALOGUE. 5 



Very near T. dioicum, from which it is most readily distinguished by the car- 

 pels ; 2-3° high ; somewhat variable in its foKage. From New Mexico to Cali- 

 fornia and northward to British America. Eare in the East Humboldt 

 Mountains ; more frequent in the Wahsatch, at an elevation of 6-9,000 feet ; 

 June-August. It is the T. Cornuti of Lyall's Oregon collection, T. hetero- 

 phyllum, Nutt. MSS. in Herb. Gray, and probably T. megacarpum, Torr., of 

 Fremont's Eeport. (7.) A form was also collected with the leaflets nearly 

 orbicular, entire or 3-lobed. (8.) 



Var. (?) With stamens mingled with the less compressed strongly ribbed 

 fruit, the styles deciduous, the raceme short and dense, and the leaves ex- 

 tremely large, 1' or more in diameter; a very doubtful form. Wahsatch 

 Mountains, Provo Canon ; 6,000 feet altitude. (9.) 



Anemone multipida, D C. Most of the specimens have but a single head ; 

 flowers light-purple. It is the same as the South American plant, but seems 

 clearly distinct from A. decapetala, with which it is united by Dr. Hooker. It is 

 the A. lanigera^ Gray, of Chili. From Vermont and Canada to Oregon and 

 Arctic America. Found on the East Humboldt and Clover Mountains of 

 Nevada, and more frequently in the Uinta Mountains, Utah, on dry rocky 

 ridges, at an elevation of 9-12,000 feet ; July-September. (10.) 



Anemone decapetala, L. (A. Caroliniana, Walt.) Two imperfect 

 fruiting specimens (one with four heads) of what appears to be this species 

 were found on Stansbury's Island in Salt Lake, Utah; altitude 4,500 feet; June. 

 From the Carolinas to Missouri, Colorado, New Mexico, and Arizona. (11.) 



Myosurus mimimus, L. From Greorgia and IlUnois westward to the 

 Pacific. Found only in a meadow near the mouth of Jordan River, Salt Lake 

 Valley, with the next. (12.) 



Myosukus aeistatus, Benth. Lond. Jour. Bot. 6. 458. Spikes oblong or 

 linear, with few to very many achenia, which are beaked with a divergent per- 

 sistent style nearly equaling the achenium. — Ordinary starved specimens have 

 short few-carpeled heads, but under favoring circumstances it sends up numer- 

 ous sub-decumbent scapes, with linear many-fruited heads, as in M. minimus. 

 Found growing in the shade of sage-brush in the valley of Carson River, 

 Nevada, and of Salt Lake ; 4,500 feet altitude ; collected also by Ives in 

 Western Arizona. April-June. A Chilian species. (13.) 



Ranunculus aquatilis, L., Var. teichophyllus, Chaix. The most com- 

 mon form of the species ; from the Eastern States and the Alleghany region
