first time that this species has an adaptation for dissemination by 
animal agencies. After passing through a patch of it I found 
many of the spikelets adhering to my clothes by their sharp 
points. I do not know whether any other species of the genus 
behaves in the same way, but not many of them have the reflexed 
spikelets which are an essential feature of this mode of dissem- 
ination. 
Cyrerus Iria L. 
This introduced species was found rather common in cultivated 
fields in. the Chattahoochee River bottoms in Early County, 
August 14 (no. 1224). Not previously reported from Georgia, 
Florida or Alabama, though there can be little doubt that it grows 
also on the other side of the river in the other two states. 
- Scirpus fontinalis sp. nov. 
Culms. tufted, 12-18 dm. long, triangular at least below, the 
summits very slender and nodding. Basal leaves few, 3-4 dm. 
long by 3-5 mm. wide; stem-leaves few or several, ascending or 
almost appressed, slender and acute: umbels compound, unequal- 
rayed, axillary and terminal, the 1—4 lateral ones on slender flattened 
drooping peduncles 1-3 dm. long: spikelets (often partly trans- 
formed into tufts of leaves) all on slender pedicels, 2-3 mm. thick, 
oblong when young, their axes elongating as the lower scales drop 
off and becoming finally about 1 cm. long: scales oblong, acute, 
concave, 1.5 mm. long, with scarious whitish margins and green 
keels: bristles 6, smooth, tortuous, about as long as the achene: 
achene light brown, oblong, triquetrous, 1 mm. long, acute at both 
ends, covered with minute depressed conical papillae, and tipped 
with the short slender base of the style. 
This species is somewhat intermediate between S. divaricatus Ell. 
and S. Zineatus Michx., but is abundantly distinct from either. It 
resembles the latter (which has not yet been reported from Georgia) 
in having axillary umbels, but differs in most of its essential char- 
acters, such as its smaller spikelets and pointless green scales, and 
others more difficult to describe. From S. divaricatus it is readily 
distinguished by its slender nodding culms, ascending leaves, long 
internodes and long-peduncled axillary umbels, as well as by its 
thicker spikelets and papillose mucronate achenes, and by its 
habitat. S. divaricatus is a stouter usually erect plant, with nu- 
merous widely spreading or deflexed leaves and a single diffuse
