Meisner based the species. In August, 1895, Mr. Nash collected 

 specimens at Palmetto, Manatee county, Florida (no. 2429). This 

 second station is in the vicinity of the original station. The geo- 

 graphic range of Polygonella ciliata seems to be very restricted.

As far as I can see, these two species must be united. Having 

 the types of both at hand I cannot find any distinctive characters 

 and in addition the labels show that Polygonella Crooniii is from 

 " South Florida," and not from " Carolina or Georgia," as Dr. 

 Chapman records in the Flora of the Southern United States.

5. Polygonella macrophylla n. sp. 



Perennial (?), stoutish, glaucous, glabrous. Stem solitary, erect, 

 S dm. tall, simple below, branched above ; leaves obovate or ob- 

 lanceolate, 2-6 cm. long (sometimes shorter on the branchlets), 

 obtuse, 3-5-nerved, leathery, exceeding the internodes except on 

 the upper part of the stem ; ocreae cylindric, slightly oblique, not 

 pointed, increasing in length toward the upper part of the stem ; 

 racemes very dense, 2-3 cm. long, disposed in ovoid panicles ; 

 ocreolae funnelform, densely imbricated, slightly pointed; pedicels 

 jointed at the middle; calyx (flowering stage not seen), the outer 

 segments slightly accrescent, the inner developing wings; fila- 

 ments subulate, somewhat dilated at the base; style 3-parted to
