46 THE CAYUGA FLORA. 



Near Cayuga Lake from Union Springs south to Farley's Point 

 and Lockwood's Plats. Marsh north of village; and on Frontenac 

 Id.; abundant within the limits. Scabiosa diners from Dipcacus, 



chiefly in the scales of the receptacle, which are either not prickly 

 or reduced to hairs. 



S. austrai.is, Wulf., is a perennial herb, %-% meter in height, with 

 few opposite branches forming a corymb. Radical leaves spatulate ; 

 cauline opposite, lower oblanceolate and tapering into a petiole, up- 

 per linear-lanceolate and sessile, entire, obtuse or acute, glabrous or 

 slightly hairy on the veins; light green. Heads on long peduncles 

 globular or oblong {\% cm.), flowers small, cerulean blue. Involu- 

 cel, glabrous, 4-lobed ; lobes short, obtuse ; calyx-lobes not extend- 

 ing into bristles. Detected Aug. 1881. The history of its intro- 

 duction (in this the only station in America so far as I know), is 

 clearer than in most such cases ; for in the Herb, of Prof'r J. J. 

 Thomas are specimens taken from his father's garden, where it was 

 cultivated fifty years ago. The garden was back from the lake only 

 a mile or two.
