280 PROCEEDINGS OP THE AMERICAN ACADEMY 



* * * Rhizomatose, the long-petioled radical leaves and flowering 



stems (bearing a pair of broad sessile leaves below the racemiform 

 nearly bractless inflorescence) from creeping and little-thickened 

 rootstocks : petals obovate and emarginate or obcordate, rose-color 

 or white : pedicels in fruit erect or ascending. 



C. SARMENTOSA, C. A. Meyer; also of Seem, Bot. Herald, as to 

 char., but the figures suspected to be of a small form of C. arctiea ; 

 they show no trace of the creeping filiform rootstocks or stolons which 

 characterize the species. Here probably, and according to Ledebour, 

 belongs G. Chcanissoi, DC. Prodr., not of Spreug. Our sjoecimens 

 are from St. Lawrence, St. Paul, and St. George Islands ; and it occurs 

 on both adjacent shores. 



C. ASA.RIFOLIA, Bongard, Veg. Sitch. 157. By its creeping root- 

 stock and hardly bracted inflorescence, this belongs to the Euclaytonia 

 section, while the habit is just that of the following species, although 

 perhaps more fleshy. The radical leaves tend to be subcordate or 

 somewhat reniform, enough so to justify the specific name, although as 

 commonly rhombic-ovate. Here belongs C. cordifolia^ Watson, Proc. 

 Am. Acad, xviii. 365, and a dwarfed form of the same is C Nevadensis, 

 Watson, Bot. Calif, i. 77. The species ranges from the Rocky Moun- 

 tains in Montana and Idaho (^Lyall, Nevius^ Watson), and the Cas- 

 cades of Oregon (^Henderson, Suksdorf), south to the Sierra Nevada 

 (Lemmon) and north to Sitka. Also Bering Island, Dr. Steiniger. 



§ 2. LiMNiA. Fibrous-rooted annuals or perennials, destitute of 

 rootstocks, corms, &c., but in one species bulbilliferous : one sepal 

 commonly a little larger than the other, and the two petals alternat- 

 ing with these disposed to be larger than the others, at least in some 

 species. 



* LiMNiA proper, including the species to which Linnaeus gave this 



name in Act. Holm. 1746, and the two species taken up by 

 Plaworth : cauline leaves the single pair of Euclaytonia, near the 

 mostly racemiform inflorescence ; radical ones numerous and peti- 

 oled : petals emarginate or obcordate : stamens always 5. 



•»— Green bracts accompanying most of the pedicels of the ample sim- 

 ply and loosely racemiform inflorescence : leaves thinnish ; cauline 

 pair distinct. Connects closely with the last preceding species.
