raceme, and the pedicels are only about one-half as long as 
those of its relative. The species has been collected several

Polygonum fugax Small sp. nov. 
Perennial from horizontal rootstocks, bright green. Stems 
erect, 3-4 dm. tall, glabrous, discolored below the nodes and 
the inflorescence: basal leaves several; blades lanceolate or 
oblong-lanceolate, 5-12 cm. long, acute, undulate, finely 
wrinkled above, minutely pubescent beneath, slightly revolute, 
cuneately narrowed at the base; petioles as long as the blades 
or longer, winged near the top: stem-leaves nearly similar 
to the basal, but with smaller and narrower blades and short 
petioles: ocreae delicate, closely surrounding the internodes 
of the stem, except the loose and obliquely open top: spike 
cylindric or nearly so, 2.5-5 cm. long, about 1 cm. thick, 
erect: bracts very delicate, light brown, ovate-lanceolate to 
oval, acuminate, 5-7 mm. long: flowers early deciduous or 
fugacious: calyxes pink; lobes various, the inner oblong, 
obtuse, the outer larger and all three of different sizes: 
stamens 8: achenes 3-angled, oval, dark brown, abruptly 
acute. 
Related to Polygonum Bistorta L., but more slender and 
with much more delicate parts throughout. The leaves differ 
from those of P. Bzstorta in having lanceolate or oblong- 
lanceolate blades with narrowed bases. The inflorescence
