Brother Leon has contributed descriptions of some grasses; Dr. John H. Barnhart the Lentibulariaceae ; Dr. Francis W. Pennell the Scrophulariaceae ; Dr. S. F. Blake has cooperated with some Card.uaceae ; Dr. Rydberg has contributed a new genus of Fabaceae and Mr. Percy Wilson has assisted at many points. Family POACEAE Paspalum Rocanum Fr. Leon, sp. nov.
