ASTER JUSSIEI 391 
Nees, Gen. Asterearum (1832) cites Cassini's Eurybia Jussiei as 
similar to Nees’ own Eurybia commixta but pr obably distinct not- 
withstanding. Nees’ eee bases s description in the form of a 
Latin summary, as follow 
Eurybia Jussiei, Liane pine a nostra specie [ Æ. commixta Nees], h 
hic addimus 
loco saltem debet intrare; cuius descriptionem auctoris verbis Folia 
longe petiolata, ovali-oblonga, fere Mi c basi cordata, apice acuta, grosse serrata, 
glabriuscula. Calathia paniculat Periclinium discum :equans, foliolis concinne 
imbricatis appressis obtusiusculis uninerviis subco iaceis apice incrassatis, quorum 
exterioribus ovalibus, interioribus linearibus. nanthium alveolatum. Radii ligulae 
longissimae, lineares, apicem versus angus s apiceque integerrimae. Disci flosculi 
lutei, Magus profunde quinquefido, rpm inaequalibus linearibus longis. — Specie 
haec, laciniarum flosculorum discoidalium ee distincta, maxime affinis est 
Asteribus SEUA et coryméoso, qui et ipsi Eurybiae sunt. 
The original specimen seeming to have parer and none 
other to have been hitherto discovered, the species rests on Cas- 
sini's description, which was rightly interpreted by Nees as sug- 
esting a somewhat different plant from the latter's comizata. 
Lanceolate leaves with sinus are rare in Aster, or indeed in other 
genera.  Paniculate inflorescence is also unusual in the Biotian 
group. Long narrow disk-lobes are much less common than 
short ones. Entire tapering terminations ending narrow rays are 
still rarest of all among the Macrophylli. This is the combination 
of four unusual characters presented by Cassini's description, the 
counterpart of which I have sought in nature through various parts 
of the Middle and New England States for eight or nine years. 
I find very few Biotian forms which show any of the four charac- 
ters, and the one form which I do find, which shows them all, I 
have described above as the representative in nature of Cassini's 
plant. 
81. Aster decaphyllus sp. nov. 
Dark deep-branched paniculate-corymbed ascending or de- 
cumbent plants with rosettes of thick, coarse-serrate oval radicals, 
reddish-brown stems, cordate-ovate, reniform and elliptic-acuminate 
leaf-series, taper-based caulines, oblong-lanceolate axiles, deep 
violet-rays, deep-slit disks, and oblong-acute white-edged bracts. 
Name, L. from Gr. — ten-leaved, from the frequency of rosettes of about ten 
leaves. 
Fic. 104, plants from Little-Indian Cr., N. Y., Au. 13, 798, reduced to $ 
nat. size; e, small half-grown plant; 4, schadet HIN leaf; d, another radical 
uster.
