Aster BigEtovit (sp. nov.) : ramis yiscido-hirsutis ad apicem usque foliosis; ramulis corym- 
bosis | monocephalis ; foliis membranaceis oblongo-lanceolatis semiamplexicaulibus grosse serratis 
tenuiter triplinerviis hirto-puberulis glabratis ; capitulis maar! amnee involueri plurise- 
rialis squamis attenuato-subulatis basi appressis superne squarroso 
recurvis glanduloso-viscidis ; acheniis glaberrimis. Arroyos in ‘the Sandia mountains ; Octo- 
ber. . A wholly new and most remarkable Aster, of the Grandiflori group ; but the apparently 
showy heads larger than those ‘of A. grandiflorus, being an inch in diameter, and the numerous 
(blue and violet) rays an inch long. It is probably a tall plant; but the base of the stem was 
not collected.. Cauline leaves two or three inches long, coarsely dentate-serrate throughout ; 
the uppermost, and those of the short branchlets, smaller and less toothed. Scales of the imbri- 
cated involucre half an inch long when extended, very slender; the long and almost filiform 
appendicular portion recurved, spreading and very glandular. Receptacle flat, alveolate ; the 
alveole short and entire. Achenia perfectly glabrous, linear, compressed, three lines leiig. 
Pappus not abundant, nearly in a single series.
