ASTER VITTATUS 257 
Rootstock reddish-brown ; finally black, with very short nodes. 
Stem deep red, or green when under shade, smooth, continu- 
ously sinuous, about 13 ft. high, finely striate when 
Leavesfull green, firm, smoothis ly narrow- v-petioled, 
acuminate-serrate with very close slender teeth, and with broad shal- 
low sinus. Radicals oblong-acute, with truncate base and straight 
sides ; or sometimes cordate-triangular. Lower leaves character- 
istic, ovate-incurve-acuminate. Middle caulines ovate-acuminate 
rounding into a wing-petiole. 
Inflorescence a loose dome, with branches upward-curved. 
Bracts of two kinds, the outer acutish or bevel-tipped, slightly 
ciliate; the middle and inner bracts very thin and smooth, non- 
ciliate, very long-attenuate, with whitish margins and with a very 
characteristic long narrow green medial band continuing without 
enlargement, to the obtuse apex. 
Habitat, grassy banks and lower mountain slopes, Schoharie 
Valley in the Catskills ; on Colonel’s Chair Mt., Hunter, flowering 
the middle of August, passing out of flower Se. 5. 
Distinguished from the similarly domed A. curvescens by its 
more green-banded and less-attenuate bracts, looser upcurved 
inflorescence branches, usual red stem, smaller more ovate leaf- 
form, and different teet 
Distinguished from A. ambiguus near which it grows, by its 
shorter non-cylindric simultaneous-flowered inflorescence, its darker 
red stem, and its narrower more sharp-serrate leaves 
Unlike A. Schreberi in its curves of stem, leaf, inflorescence top 
and branches ; also in its narrow green-banded bracts.
