PAYSON—MONOGRAPH OF THE GENUS LESQUERELLA 203 
horizontal or ascending, 7-11 mm. long; pods horizontal or 
ascending, sessile, sparsely stellate-pubescent or glabrous, glo- 
bose, 1-2 mm. in diameter; styles filiform, 2-3 mm. long, stigma 
capitate; septum slightly nerved at the apex, areolae scarcely, 
if at all, tortuous; ovules 1-2 in each cell, funiculi attached to 
the septum for one-half their lengths or less; seeds nearly or quite 
filling the pods, not margined, radical somewhat turned to one 
side. 
Distribution: Kentucky and northern Tennessee. 
Specimens examined: 
Kentucky: rocky soil, Valley View, May 16, 1903, Biltmore 
Herb. 4273a (U. S. Nat. Herb.); banks of Kentucky River, 
Frankfort, Lesquereux (Mo. Bot. Gard. Herb.). 
Tennessee: limestone bluffs, Whites Bend, Davidson County, 
May 25, 1899, Biltmore Herb. 4273 (U. S. Nat. Herb.) ; Nashville, 
1886, Gattinger (U. S. Nat. Herb.); Rising Sun Bluff, 14 miles 
below Nashville, April-May, 1886, Gattinger (U. S. Nat. Herb. 
and Mo. Bot. Gard. Herb.). 
The original description of Vesicaria globosa Desv. is scarcely 
sufficient to confirm its specific identity with V. Shortii Gray, 
and this uncertainty is increased by reference to the ‘Kew In- 
dex’ and Kuntze’s ‘Revision’ in which it is considered identical 
with ludoviciana (argentea MacM.). Fortunately, however, 
Dr. F. Gagnepain, of the Museum of Natural History in Paris, 
to whom fragments of L. argentea and L. globosa were sent, was 
able to confirm the present treatment by comparison with Des- 
vaux's type. Dr. Gagnepain adds that the label on the type 
sheet reads V. globulosa instead of V. globosa. 
L. globosa is apparently without close relatives in the genus 
and one is at a loss to know to which group of species to ally it. 
That its affinities are with this genus, however, there seems 
little doubt. 'The species may be readily recognized by the 
very numerous, small pods and the straight pedicels together 
with the conspicuously branching stems.
