this species gathered during the summer of 1897 at Apalachicola, 
Florida. 
HYDROCOTYLE BONARIENSIS Lam. Encycl. 3: 153. 1788.— Another 
station in the United States for this fugitive may be added, the species 
being abundantly and thoroughly established in the vicinity of the 
ballast dumps at Wilmington, N. C., where it was collected in fruit 
and flower, July 2, 1897. 
CAREX LAXICULMIS Schwein. Ann. Lyc. N. Y. 1: 70. 1824.—On 
May 13, 1898, in Henderson county, North Carolina, C. laxiculmis 
was found with nearly mature perigynia. I believe ‘this is the first 
record of the species as belonging to the southern flora.—C. D. 
BEADLE, Biltmore Herbarium. 
A NEW SPECIES OF APIOS FROM KENTUCKY. 
Tue plant here characterized was discovered some years ago in open 
woods and thickets near Bowling Green, Kentucky, by Miss Sadie F. 
Price. After noticing for several seasons its occurrence and peculiar 
characters, Miss Price, who recognized its genus and believed it a 
new species, sent it to Professor Charles F. Wheeler of Michigan Agri- 
cultural College for further examination. Professor Wheeler, after 
making dissections and comparisons, concurred in the view that it rep- 
resented an undescribed Apios, but with undue modesty has declined 
to characterize it, and Miss Price has recently referred flowering and 
fruiting specimens, together with careful drawings, to the writer. The 
species for several reasons possesses more than ordinary interest. It is 
a second American member of a small but well-known genus. Like 
its congeners it has farinaceous tuberiform roots, but these attain much 
more considerable proportions and suggest a possible utility in culti- 
vation. Furthermore, the corolla has a somewhat peculiar form, the 
standard being provided at the apex with a thick, spongy, knot-like 
prolongation. Any homologue of this appendage which may exist in 
the other known species is so rudimentary, if present at all, that its 
occurrence here seems to warrant the separation of this species as 4 
subgenus. The genus may thus be divided into two subgenera as 
follows : 
Evapios. Standard suborbicular, rounded or retuse at the unthick- 
ened summit. Roots (as far as known) fibrous or moniliform-tuberous.
