ASTER EXACUTUS 261 
long, about 3 in. broad, with long slender petioles ; their broad 
sinus open and shallow or closed by overlapping ; the basal lobes 
elegantly rounded. Upper and lower caulines are typically elliptic- 
acute or oblong-lanceolate, numerous and close, spreading and 
horizontal, nearly or quite sessile, 3X Lin. or becoming finally half 
that size, ‘sharp- -serrulate or finally subentire. Axiles steadily 
diminished from the last. Rameals small and inconspicuous, 
rather numerous, lanceolate or oval-oblong. 
Teeth of slit-serrate type, remarkably uniform throughout the 
plant, very close, long-acuminate, directed outward on the best 
developed lower leaves, directed forward on the middle and upper 
caulines. 
Leaves glabrous, their upper surface rough, the lower smooth. 
Petioles to the radicals exceed the leaf-length and are notably long 
and slender. Radicals of typical development are usually pre- 
ceded by a small subcircular primordial, 1 in. or more broad, 
with crenate teeth or shallow sinus. 
Inflorescence flat-topped, a typical compound corymb of high- 
ascending successively-lengthened branches, nearly simultaneous 
in flower, with small heads ¥ in. high. 
racts coriaceous, rather cli, somewhat keeled along the mid- 
rib, somewhat short- ciliate, pale, but with small deep-green tips, 
all narrow, mostly linear-attenuate with obtuse apex. Rays nar- 
row, creamy, about 8. Pappus becoming ferruginous. 
With A. Schrebert, from which it seems a very distinct offshoot.
