New Species of Trautvetteria. 



Trautvetteria nervata. Basal leaves not of the largest, 

 pedately rather than palmately parted almost to the base, the 

 primary segments narrow, their lobes almost divaricate, form- 

 ing oblong sinuses by overlapping each other above : flowers 

 not known : achenes numerous, much compressed, obliquely 

 somewhat lunate, narrow at base, a distinct nerve or promi- 

 nent secondary vein traversing each interval between two 

 primary ribs, the whole head round-ovate rather than spherical. 



In rich damp woods near Dublin, Georgia, 21 June, 1902, 

 collected by Roland Harper. It is the first strongly marked 

 species that has been added to genus since its establishment ; 

 both the one belonging to the Pacific coast of America, and 

 the Japanese species, differing from the Atlantic American 

 type by no very striking peculiarities. But this Georgian 

 species at the very first glance at even the foliage declares 

 itself as something well marked and distinct ; and the ovate 

 heads of achenes are another peculiarity that is obvious 

 enough ; but the secondary nerves, running the whole length 

 of the carpel, constitute a character which calls for an amend- 

 ment of the diagnosis of the genus. So also does the nature 

 of the achene as being much compressed laterally after the 

 manner of Thalictrum. 



Trautvetteria fimbriata. Foliage not large, of firmer 



texture than in T. grandis, of a lighter green, almost glauces- 

 cent beneath, the radical leaf of suborbicular contour and 6 

 inches across, deeply cut into 5 or 7 subrhomboid segments 

 entire as to their cuneate-tapering base, the rest of the seg- 

 ment fimbriate-lacerate : both the cyme and the individual 

 flower very large for the plant, and stamens excessively 

 numerous: achenes small, slightly compressed, broadest at 

 about the middle, tapering abruptly to each end, the space 

 between the ventral rib or angle and the lateral showing a 

 very prominent nerve which, as a branch of the ventral, runs
