S. RUBROTINCTUS, var. confertus. Rays of inflorescence short: 
glomerules compacted into dense clusters 1.5 to 4 cm. in diameter. — 
Green, Maing, July 10, 1878 (F. Lamson-Scribner). A dense-headed 
extreme parallel with S. cyperinus, var. condensatus, and S. atrocinctus, 
var. órachypodus. 
S. SYLVATICUS, L., var. Bissellii. Spikelets linear or linear-oblong, 
7 to 10 mm. long, in dense glomerules: sheaths conspicuously red- 
dened below as in S. rwórofincfus. — In a swamp at Southington, 
CONNECTICUT, July 22, 1898, no. 716, July 6, 1899 (C. ZZ. Bissell) ; 
July 23, 1898 (Luman Andrews). An extremely long-spiked form 
with the sheaths more brightly colored than in the species, suggesting 
S. rubrotinctus : in its 3-cleft style, pale brown definitely angled achene, 
and other floral characters, clearly an extreme form of S. sy/vaticus. 
In its development of long narrow spikes this plant exhibits a tendency 
which is paralleled in other species of Scirpus — as S. cyperinus, var. 
Andrewsti, S. pedicellatus, var. pullus, and S. atrocinctus, var. grandis 
described above, and S. polyphyllus, var. macrostachys, Bockeler (S. 
Peckit, Britton).
