ally common in the colonies, similar, on longer petioles, 2.5 to 12 cm. 
wide. Leaflets glabrous to pubescent, sparingly ciliolate, simple and 
linear or narrowly lanceolate to ovate, and 1- to 3-lobed, -divided, or 
somewhat multifid, sparingly appressed-serrate to laciniate or gash- 
toothed, mucronate: those of the stem scarcely petiolate, of the base 
distinctly so. Flowers white or purple-tinted: petals ro to 16 rarely 
18 mm. long. Pedicels in flower 0.3 to 2.5 cm. long, in fruit 1 to 2 
and sometimes 3.5 cm. long. Pods common, strongly ascending on 
stout pedicels, 2 to 4.5 cm. long including style 6 to 9 mm. long. 
In rich damp or often springy soils containing much humus, in 
woods or along their borders. Apparently rather rare eastward 
(Killingly and Old Lyme, C. Z. Bissell), it is found at infrequent 
intervals throughout a large part of central and western Connecticut 
away from the coast, sometimes in large colonies, as in Plainville, 
C. Hf, Bissell, and in Gaylordsville, Austin & Eames. Our earliest 
species to flower.

College as sophomore in the spring of 1850, and was graduated in

pany, removing in 1878 to Bridgeport, Connecticut, where the rest

necessary by a severe attack of gall stone just on the eve of a pro- 
posed trip to Europe, June ro. He is survived by a wife, two sons 
and three daughters.
