separate genera destroys the whole genetic balance. To keep 

 them in one large genus preserves that balance and enables 

 any student to see at a glance the relationship of the groups 

 which is one of the prime requisites of systematic botany. 

 True it spoils the chance to make a set of new combinations 

 \v;(h one's name as the botanical tail to them which I consider 

 a misfortune even when necessary as is the case with Lo- 

 matium. The only character that would separate Cynomar- 

 athrum from Lomatium they destroy in admitting C. Brand- 

 cgei in the genus with ternate and not pinnate leaves. 

 Cogswellia montana (C. & R.) 



Roots very fleshy, erect and elongated, sometimes an inch 

 thick, mostly single and tapering above, and below produc- 

 ing several n?irrow lateral rootlets which sometimes enlarge 

 into small fusiform tubers, and at base with more or less large 

 and tapering branches ; crowns small, narrow and elongated, of 

 one to few, loose, stout peduncles surrounded by few very long 

 and purplish hyaline leaf sheaths which are slightly fibrous 

 with age: acquiescent; leaves ternate and then pinnate, the 

 primary divisions all stalked, each division appearing bipin- 

 nate. the pinnae being ovate, 3-9 lines long, and then divided 

 nearly to the midrib into oblong-oblanceolate and obtuse seg- 

 ments about 3-4 lines long, blades 3-4 inches long, the petioles 

 either very short or even 6 inches long and gradually enlarg- 

 mg below into the very long and hyaline sheaths ; whole plant 

 glabrous and bright green, general outline of leaves ovate ; in- 

 volucres none; involucels many, broad, striate, hyaline-mar- 

 reflexed, obovate to oblanceolate smooth bracts about 

 hues long; rays stout i/^-3 inches long, several; pedicels 

 ..w. over 2 Imes long, slender and erect or ascending ; fruit 3-4 

 lines long and li/4-2 lines wide, elliptical, barely emarginate 

 at both ends, wmgs about one-third the bodv and thin; oil 

 tubes appeanng as if one in the intervals and filling them but 

 really about 2-3 and coalescing, appearing as if 2 on the com- 

 missure but really 6 and sinuous; dorsal ribs raised and sharp 

 and at least one of them generally raised and wing-like but 

 nex^r over ki the width of the laterals. High alpine on Mt. 

 Bndger. Montana. Aug. 10. 1906. This plant is manifestly 

 a congener to C. juniperina and certainly does not belong 

 to the farmosa group where Coulter and Rose placed it. 

 tnough It is a close relative of what they have named C 

 <^ous and C. circumdatum which both have the same winged
