Alabama Flora. 
By CHARLEs Monr. 
(PLATES 289-291). 
’ SAGITTARIA VISCOSA Nn. sp. 
Monoecious, scape slender, erect, over two feet long, exceeding 
the leaves, sparingly branched from the lowest verticil ; leaves mem- 
branaceous, smooth, broadly ovate, rounded towards the slightly 
apiculate apex ; lamina 6/—7’ wide, 12/-14’ long, deeply sagittate, 
the broad lobes acute, 6’ long, at first gradually, finally widely 
_ Spreading; panicle slender, main branch 12/—1 3’ long, the branches 
about half its length; bracts coriaceous, papillose, rugose, viscid, 
free at the base, oblong-ovate, obtuse; verticils on the main 
‘stem 8-10, distant, with 2-3, rarely more flowers borne on slen- 
der, rigid, erect, spreading pedicels, about 1’ long, those of the 3-4 
fertile verticils little shorter ; sepals thick, and like the bracts 
papillose, glutinous, ovate, lanceolate ; stamens numerous (20-25), 
i long, filament two-thirds longer than the anther, scarcely at- 
tenuate and strongly villous towards the base; immature achenes 
with a slender erect beak, narrowly winged; flowers large, fully 34’ 
across. (Plate 289.) 
Deep muddy borders of marsh on the Mobile river, May 28, 
1896. Ona second visit to the same locality to collect specimens 
with the rhizome and mature fruit the plants were destroyed by 
the clearing and partial drainage of the front of the marsh. 
At oncé recognized from its allies of the same group, by the thin ; 
leaves, papillose viscid bracts and sepals. Type in herbarium of 
the Geological Survey of Alabama.

‘‘ Leaves lanceolate-linear, long attenuate to the acute apex, 
_ tapering gradually to the slender ascending petiole, 15’-20’ long 
by 36’-14' wide; scape, with 6-8 verticils shorter than the leaves, 
‘simple, triquetrous, weak, declining and decumbent after flowering, 
frequently ripening the fruit under water; the inflorescence nar- 
Towly pyramidal, bracts 34/-14’ long, connected in the middle, 
fertile pedicels spreading, somewhat longer than the sterile in 3-4 
Verticils, 34/54’ long ; sepals oblong, obtuse, ;/’- 18’ long, stamens _ 
9-12, anthers broadly elliptical; achenes crenulately cre ed, 
broadly winged, the broad margins laterally unicostate or narrowly — on
