SYNGENESIA SUPERFLtfA. 
S. Odora. Mich. 2. p. 118. 
Stem about three feet high, very pubescent towards the summit. Leaves 
numerous, linear-lanceolate, with a few distinct serratures, sometimes pube- 
scent underneath, obscurely triplinerved, generally twisted. Flowers in a 
very compact panicle, the racemes handsomely recurved, bearing near the 
base, a number of small buds that never mature. Scales of the involucrum 
linear-lanceolate, rather obtuse, nearly glabrous. Florets of the ray three 
to five; of the disk about the same number. Seeds pubescent. 
Grows in dry pastures with the preceding, from which, however, it is very 
distinct. 
Flowers August — October.
