37. Carex Sartwelliana, Olney, Proc. Amer. Acad. vii. 396. 

 Whole plaut softly pubescent : culm two to three feet high, rigid : 



leaves about two lines broad, about the length of the culm : bracts 

 leafy, sheathless : stamiuate spike one, sometimes bearing a few pistil- 

 late flowers : pistillate spikes four or five, sessile, an inch or two long, 

 densely flowered, ferrugineous : perigynium trigonous-obovoid, mi- 

 nutely beaked, the orifice entire, densely tomentose, a little longer 

 than the mucronate purple-margined and ciliate scale. — Named in 

 memory of Dr. Henry P. Sartwell of Penn Yan, New York, an 

 ardent botanist, an early student of this genus, and author of an Ex-

39. Cauex hirtissima, W. Boott, Bot. Calif, ii. 247. 



Culm rather slender but strict, a foot and a half high, smooth : leaves 

 shorter than the culm, pubescent, those on the culm producing conspic- 

 uous pubescent sheaths : spikes three or four, the upper short-stalked, 

 erect, about an inch long, scattered rather loosely flowered, usually ex- 

 ceeded by the leafy bracts : perigynium triangular-elliptic, contracted 

 at both ends, nerveless or nearly so, hirsute, ribbed on the angles, pro- 

 duced abruptly into a slender beak, about the length of the white and 

 very abruptly ai'istate scale. The beak becomes more or less bifid by 

 splitting at full or over maturity. — Summit Camp, Sierra Nevada, 

 California, Dr. Kellogg.

 C. Halllana, Bailey, Bot. Gaz. ix. 117. 



Culm a foot high, smooth or nearly so, very leafy : bracts leaf- 

 like, with thin white auricles, the lower exceeding the culm : pistillate 

 spikes about three, an inch long, often staminate at the top, erect, ap- 

 proximate, shortly peduncled : perigynium ovate, tapering at both ends, 

 prominently many-nerved, thickly covered with short stiff hairs, grad- 

 ually produced into a white and smooth toothed beak, longer than the 

 ovate, acute, membranaceous, and often dull-margined scale : achenium 

 large, triangular-obovoid or rarely lenticular-obovoid. — Name given 

 by Mr. Olney in the list of Hall's Oregon plants without description, 

 and the numbers of the collection became mixed. In the Olney
