 lected by John 1. and Alice R. Northrop along Fresh Creek, 

 Andros Island, June 10, 1890, no. 743; and by Robert Combs 

 along rocky sea banks near Calicita, Cuba, Aug. 24, 1895,

 Wright, but differs iu the foliar characters, the much smaller 

 flowers, and the more pubescent achenes." — Plate xxxvi.
