282 DESCRIPTION OF ASTERS ; CURVESCENTES 
lum alatum contractis glabris supra in ambitu scabris, caule decomposito-corymboso 
glabro, periclinii arcte imbricati foliolis oblongis obtusis, radio periclinio longiore. 
(Characteres specierum in isto genere [Eurybia] paulo ampliores dedimus, scilicet ut 
iis quoque inserviant, quibus genus Eurybisze ab Asteribus sejunctum non probetur). 
a. Foliis radicalibus reniformi-orbiculatis, radio ro pappo ferrugineo.

[So far all applies to du original 4. Schreberi Nees, of 1818, which alone is 
retained under that name in this present monograph. Nees now, 1832, adds a second 
variety, 2, including at least two types which I restore to specific rank, A. subcymosus 
and 4. ambiguus. 
8. Foliis radicalibus saepe ovato-orbiculatis, caulinis magis acuminatis, ple- 
risque longe —— petiolatis, radio elongato, pappo albo, calathiis minoribus.

Aster ambiguus Bernh. Horti Vratisl., ex Hort. Erfort. [For this see 
species 52.] 
Aster discolor Hort, Hamb, [An uncertain form, which must remain a 
synonym of 4. subcymosus in lack of evidence. Its name has been since used for £7o/7a 
discolor of Manchuria, so called from the contrast of the leaves above and beneath. 
if it had such a contrast between the two leaf-surfaces, as to suggest the name, or if it 
had two colors as lavender and white in its rays, it would be sufficiently unlike other 
Schreberan species to call for separation. Perhaps it was a case like A. Ertensis in 
w ys are occasionally part deep rose-color in the otherwise white head. If 
its name merely alluded to the rays and disk being of unlike colors, or to the: disk 
changing from yellow to a perfectly new color later, all that would be true of any Aster. ]

of 1818 pone at Erlangen during the yes that he was director of its botanic 
garden. Now in 1832, at Breslau, he has 4. ambiguus in cultivation and it blooms 
with him in September as it does with us in the Catskills. e had dried specimens he 
identified with 4. Schreberi, sent from Bernhardi? or referred to others seen by him in 
Breslau in the Günther herbarium sent from rerit by Póppig. ]

Which really are strong contrasts both to Nees' descri ription of 4. glomeratus and to our 
native 4. iie atus specimens, are as follows: A. Schreberi has long-petioles pre- 
dominant, instead of short; it has smoother leaves; it has more slender-acuminate 
iles. ]
