("iiKst-ningos niid foot-liills of the Siorm Nnvmla. Tliis sjiocic.s is cnsily rn-ofjnizcd by its sloii- 

 (l(>r liiil)it, iiiimitc (lowers, and nMiglienod akcnea. I, ike our other annuals it is very variable, 

 and at lirst sight some of tlie forms seem strikingly unlike others. 



In addition to tlie preceding species, Ji. fa-trindarix, Muhl, has lioen rcfwrted from the State, 

 bat Professor Gray (Vroc. Am. Acad. viii. 373) thinks the species is not found west of the 

 Wocky Mountains. "What lias been so called from ('alifornia is jirolwbly R. Culi/oniietit, 

 Mcnth." 



H. Ciiii.I':nsis, DC, occurred in the collections of Captain Hccchey's voyage, from California 

 (Mot. Heech. 134). Tlie sjwcies has procumbent stems, hispid petioles, cordate-orbicular, 3-5-lol)ed 

 leaves, the lobes dentate. This sjiccics has not been found in the SUite since, and it is pioljable 

 that the si)ecimeii may have got into the Californian cidlection from the Chilian, or else that the 

 species was once introduced but failetl to siirvive. 



H. MiniicA'rrs, L., a low coarse annual sjiecies from Kurope, with large very rough akenes, 

 and flat stout recui-ved beaks, has been lejiortcd from "the streets of Sun Kianci.s('o " (Holander's 

 Catalogue, 3). 



6. CALTHA, Linn.

 nnnioroMs. Pistils 6 to 12, each with several ovules, becoming follicles in fruit, 

 wliieli at ripeniiif^ aro spreading, ilattened, and sovcral-secdcd. — Glabrous perennial 

 lierbs, with broad cordate undivided leaves. 



A small genus of about 9 species, belonging to the cooler parts of both hemispheres. 



1. C. leptosepala, DC Stems erect, l-flowornd and scape-like, 3 to 12 inches 

 high, and exceeding the leaves ; leaves all i-adical, cordate. 



Swamps near head of King's River, at 8,000 feet (Breirrr), near Lassen's Peak, J>mmon ; also 

 alpine .stations from New Mexico and the Hocky Mountains to Ala.ska. Californian specimens 

 have the leaves 2 or 3 inches across, cordate-orbicular, margins nearly entire ; sepals greenish- 

 white, 6 to 10 lines long, and 4 or 5 lines broad, and rather blunt. Rocky Mountain speci- 

 mens have sepals usually narrower, often bluish ; the leaves ovate, cordate, and more or less cro- 

 iiate. Sometimes the stems bear a second and smaller flower, and the s|)ecie5 appears to pass 

 into '". hiflnrn. 



7. ISOPYRUM, Linn. 



Sepals usually ;">, white and ]»clal like, deciduous. Petals, in our sjiocics none 

 (in foreign species f), minute). Stamens 10 to 40. Pistils usually 3 to G, but in- 

 definite ; becoming follii.-les in fruit, which aro scvend-seedcd, oblong or ovate, and 

 pointed with the jiereistent style. — Smooth, slender herlis, with 2 - 3-t<?rnately 

 compound leaves, and axillary or terminal flowers. 



Species 7, belonging the North Temperate zone of both contincnt.s.
