 1-2 feet high, branching. Lower leaves on long petioles. Racemes numerous, naked. 

 Calj-^t-segments spreading in fruit. Corolla purplish red. Nuts large, densely covered with 

 rigid prickles.

 unpleasant smell, which has been compared to that of mice. It is quite annoying to wool- 

 growers, owing to its rough adhering nuts, which resemble little burs.

Perennial. Stem 2-3 feet high, erect, simple, clothed with whitish spreading or retrorse

 petiole : stem-leaves smaller, and somewhat auriculate at the base. Peduncle 3-6 inches 

 long. Flowers in a terminal corymb or panicle, which consists of two or three divisions ; the 

 lower flowers in each division a raceme, on elongated pedicels. Segments of the calyx oblong. 

 Corolla pale blue or nearly white ; the tube as long as the calyx ; the throat closed by five 

 httle connivent pouches, which are formed by the protrusion of the corolla inward, having pits 

 or cavities on the outside. Nuts as in the preceding species. 



Rocky woods in rich soils ; on the Hudson, above the Highlands. May - June. The 

 mucilaginous root is used for colds, and as a poultice for sprains, etc. As Dr. Darlington 

 remarks, it serves very well to amuse the patient.
