NEW SPECIES OV TRAUTVKTTERIA. 191 



diagonally to about the middle of the achene and there ends 

 abruptly ; style prominent, but not long as in T. g-raudis. 



A beautiful and well marked species, evidently rare, known 

 only as collected by W. C. Cusick, in **subalpine bogs and 

 stream banks '* of eastern Oregon, in June and July of 1886. 

 The leaves in this show narrowly V-shaped sinuses between 

 all the main segments ; another distinctive mark. Appar- 

 ently of this species is a specimen from the Blue Mountains, 



July 



Washing t 



Trautvetteria applanta. Plant not large, 114 feet 



high, the radical leaf 6 inches broad or less, subtruncate at 

 base, the sinuses between the lobes oblong, nearly closed, the 

 lobes rather evenly and very acutely serrate-toothed, the 

 whole leaf very firm and strongly veined and nerved : achenes 

 many, much more compressed than in other species, the sides 

 obliquely elongated oval, not narrowed sensibly at either end, 

 the summit appearing obtuse, the short style so lateral as to 

 appear below the geometric summit of the achene, the sides 

 commonly showing a longer or shorter nerve between the 

 ventral angle and the lateral. 



The habitat of this is the middle West southward, beyond 

 the Mississippi. The specimens before me are from southern 

 Missouri, and were gathered at Monteer, by B. F. Bush 27 

 July, 1899. It is said to be common on river bluflfs, presum- 

 ably wooded. 



i 



Trautvetteria rotundata. Plant of the largest, with 

 ample foliage thin and not obviously veiny ; radical leaf 9 

 inches wide, parted nearly to the base, the sinuses narrowly 

 oblong, mostly closed, the segments coarsely and unevenly 

 somewhat incise-toothed, but the teeth obtusish : heads of 

 carpels small, globose, the achene as broad as long and sub- 

 orbicular, not much inflated, the style rather long.
