are specimens from Chloride, the ilualapai Mts. and the 

 Grand Canon all gathered in May or late April of the same 

 year. Intergrading material comes from the same localities. 

 Intergrades with smooth pods, small bracts and several od 

 tubes come from Pine south of Flagstaff. 1890. Pleasant Canon, 



doubtless what Coulter and Rose have referred to C. orientalis 



barium has very small, distinct, nearly hvaline bracts, more 

 glaucous leaves," and umbels in flower wath nearly equal rays. 

 It may pass into C Nevadensis. but I have seen no intergrades. 

 Cogswellia Sonne! was gathered by me and distributed as 

 a Peucedanum without name from Reno, Nevada, in 1882 as 

 Xo. 3879. I have what seems to be the same thing from 

 Shepherd Canon. Argus Mountains, California. 

 Cogswellia tniPefolia var. depauperata n. var. 

 Primary divisions of leaves with nearly linear pinnae 

 which are dissected into minute linear segments, the leaves 

 without petioles and very short, and pinnae remote ; oil tubes 

 2 on the commissure. A very remarkable form and the most 

 common one in the deserts. Dugwav, Dutch Mountain, 

 Granite Mountains. Cove Creek, Detroit, Fish Springs, etc., 

 western Utah. 



Cogswellia decipiens n. sp. 



Caespitose and acaulescent from a thick and fleshy erect 

 root; crowns several, narrow wnth a few somewhat fibrous 

 clead sheaths and several leafless hyaline living ones about an 

 inch long: whole plant except the fruit and pedicels rough 

 hairv even to the sheaths; leaves without petioles (except the. 

 hyalme sheath, which is an inch long), ternate and then bi- 

 pmnate. 2-3 inches long, the final segments oblong-oblanceo- 

 late and sharnly apiculate, about 1-2 lines long; peduncles 

 slender and flexuous, many, some shorter than the leaves and 

 some much longer; umbels inclined to be one-sided, with one 

 to few stout rays an inch or two long and several slender and 

 shorter ones, but not proliferous ; most of the flowers aborting, 

 deep yellow and mixed with purple ones, very small ; invo- 

 lucres occasionally present as a hyaline bract; involucels re- 

 auced to a hyalme and very minute collar, which sometimes 

 IS produced mto a few subulate bracts, but very small; pedi- 

 ce s m flower very short, in fruit 1-3 lines long and stout" im- 

 mature fruit 3 hnes long, elliptical and with narrow wing,
