November 9-12, 1903 (no. 791), and in March, 1904, it was col- 
lected by Dr. Britton in the same region (no. 264).: 
Gaura simulans sp. nov. 
Biennial, pubescent up to the flowers: stem erect, 1-2 dm. tall, the 
late, 5.5-6 mm. long, obtuse, glabrous: petals pinkish, 4.5-5 m 
long, the blades oval, longer than the claw: style glabrous: fruit 
0.5-10 mm. long, glabrous, abruptly narrowed at the base. 
A species related to Gaura angustifolia Michx. but readily dis- 
tinguished by the glabrous buds and fruit. The fruit, too, is of a 
different shape, being relatively much broader and abruptly con- 
tracted at the base. The type-specimens were collected in the 
pinelands between Cocoanut Grove and Cutler, November, 1903 
(Small & Carter, no. 766). Other specimens belonging here are: 
Ft. Myers, Aztchcock, no. 123. 
Miami, Small € Nash, November, igot. 
Virginia Key, Brztton, no 102. 
Between Cocoanut Grove and Cutler, Small & Weilson, no. 1591. 
Proserpinaca platycarpa sp. nov. 
Perennial, glabrous: stem and branches 1-3.5 cm. long, very 
leafy: leaf-blades uniform or the lower ones with more prominently 
toothed blades than the upper; blades oblong or elliptic, or slightly 
broadened upward, 1.5-5.5 cm. long, sharply serrate: sepals nee 
or ia deltoid, barely 1 mm. long: hypanthium ridge-w 
fruits 4-5 mm. wide, constricted above the middle, the ae thus 
ene dilated. 
Most nearly related to Proserpinaca palustrés and with the same 
habit, differing most markedly in the fruit, which is constricted 
under the apex, thus forming abruptly dilated angles. The type- 
specimens were collected in the everglades west of Camp Jackson, 
y Dr. Britton, in March, 1904 (no. 239). Similar specimens are: 
Braidentown, 7racy, no. 7136. 
Ft. Myers, Afztchcock, no. 93. 
Between Cutler and Camp Longview, Small dé: Carter, no. 1466. 
Camp Jackson, Small & Welson, no. 1861.
