NOTEWORTHY VASCULAR PLANT COLLECTIONS FROM THE RED RIVER OF ARKANSAS AND LOUISIANA, U.S.A.

摘要

A plant collecting excursion by boat on a ca. 50 km stretch of the Red River straddling the Arkansas-Louisiana state line yielded several interesting botanical discoveries. The second record of Loejlingia squarrosa from Arkansas was documented. Collections of Dalea anata and Heliotropium convolvulaceum were made from both states. These collections extend the ranges of these taxa several hundred river-km downstream on the Red River. Our collections of D. anata and H. convolvulaceum in Louisiana represent the first records of these species for that state.
