Columbia University (" Red River, Dr. Pitcher "), excluding its va- 

 riety, which may be separately characterized as follows : 



Pubescence throughout denser and more pilose than in the 

 type, the smaller and narrower leaves dull grayish green, the leaf- 

 lets much narrower and dentate rather than crenate, the pairs 

 closer and often more numerous. The hairs of the stem are 

 longer and weaker than in the type and often loosely appressed, 

 the pubescence above tending to become dense and pilose-canes- 

 cent. The leaflets are mostly 4. pairs, though often 5-6 pairs on 

 the narrowed lower leaves, narrowly-oblong (linear- or lanceolate- 

 oblong) to elliptic, often inequilateral and backwardly subfalcate, 

 blunt or subacute, abruptly narrowed or rounded at the sessile 

 base, mostly dentate or dentate-serrate, often with broad, shallow, 

 uneven teeth, the odd one mostly sessile, or when petiolulate fre- 

 quently cleft basally into a pair of narrow decurrent lobes, above 

 finely pubescent to softly appressed pilose, whitened below and 

 softly appressed pubescent, the veins pilose, subleaflets narrower 

 than in the type, often borne well forward in the interspace. 

 Stipules irregularly cut-serrate or dentate-lobed, usually less in- 

 cised than in the type with shorter termination, the upper ones 

 often dentate-serrate on the inner margin and more spreading. 

 Fruit often with more convex disk and longer more spreading 

 bristles, usually also with a perceptible rim. Apparently the 

 tuberous thickenings of the roots tend to become stouter than in 

 type and to develop on shorter roots; the largest found were S/^' 

 long by 3)4" thick. (Plate 282, fig. 4.) 



The specimens that have come under my observation would 

 appear to indicate that this form was of more coastwise range than 

 the type extending from southern New York to Virginia Reach 

 and to middle North Carolina and East Tennessee. 



5. Agrimonia Brittoniana n. sp. 



Becoming stout and tall and strongly virgate-branched, 2°- 

 7° high (6° 9' at York Harbor, Maine), the stems sometimes 

 4"_5"' thick at the base, erect, but often leaning under the weight 

 of the heavy fruiting racemes, somewhat aromatic. Stem rough- 

 ened with glandular papillae and hirsute with short spreading 

 brownish hair which passes into a downy or pilose-hairy pubes- 

 cence in the racemes. Leaves numerous, often ascending or subap- 

 pressed, 4'-8' long, 2'-4' wide, the villous pubescent leafstalks downy- 

 tomentose on the upper side. Leaflets 3-4 pairs or 5-6 pairs on the 

 narrower and longer-petioled lower leaves, often directed sharply 

 forward, strongly veined, becoming thickish and rugose, dark green 

 above and more or less hispidulous or scabrous, at least near the 

 edges, the margins finely ciliolate, below paler and pubescent (soft-
