var. macrochloena nob. 



Very robust with four short and heavy pistillate spikes ; 

 perigynium very large and longer than the simply mucronate 

 scale. 



St. Paul Island, Bering Sea, collected by Mr. James M. 

 Macoun. 



Car ex nesophila sp. n. 



Bhizome stoloniferous with light brown, fibrillose, scale-like 

 leaves ; leaves shorter than the culm, relatively broad and flat, 

 glabrous ; culm very variable in height from 12 to 38 cm , erect, 

 slightly bent near the apex, glabrous, phyllopodic ; spikes from 

 two to four,* the terminal stamiuate, the lateral pistillate or 

 very seldom androgynous, contiguous, sessile and erect or the 

 lowermost borne on exserted peduncles and, sometimes, nod- 

 ding, all subtended by sheathless bracts with blades about as 

 long as the inflorescence or shorter ; scale of stamiuate flower 

 elliptical, acute, deep purplish with three green mid veins ; scale 

 of pistillate flower broadly elliptical, acute, purplish to almost 

 black with faintly visible midrib of three veins ; perigynium a 

 little longer, but narrower than the scale, sessile, erect, from 

 oval to elliptical oblong, few-nerved, pale green, the beak 

 purplish, very short, entire or obliquely cut ; stigmata three or, 

 sometimes, two, the style not exserted. 



St. Paul Island, Bering Sea : abundant' on uplands with 

 Sieversia Jtossii, Artemisia globularis and Potentilla vtllosa, 

 but not associated with any species of Carex, collected by Mr. 

 James M. Macoun (J^os. 16,614 and 16) ; also on Popofl Island, 

 Shumagin Islands, by Mr. T. Kincaid. 



Carex nesophila resembles sometimes certain forms of C. 

 salina, but the structure of the perigynium is always more like 

 that of C. macrochceta, besides the spikes being contiguous. 

 Although being a rather inconspicuous plant it has been col- 

 lected in great numbers and only on the islands in Bering Sea, 

 hence the name "nesophila." 



Carex Schottii Dew. (figs. 10-11). 



The species was originally founded on immature specimens 

 from Santa Barbara, California, some of which are in the her- 

 barium at Kew ; Mr. Clarke has examined these and informed 

 us that Bolander's specimens No. 1570, collected in swamps at 

 Oakland and in salt-marshes near Fort Point, San Francisco,, 

 are identical with these ; also identical with Bolander's plant 



* As to the number of spikes we find in twenty -two specimens : 

 15 specimens with 3 lateral spikes.
