ASTER MACROPHYLLUS 309 
SPRENGEL in the 16th edition of Linnaeus’ Systema Vegetabiliunt, 
, 8: 532 (1826), described A. macrophyllus rather confusedly, but 
contributed to the growing mass of recognized characters, these 
that “ the corymb-branches are rigid," and “ the bracts appressed.” 
He included both colors, saying “ radius caeruleus seu albus"; 
although also recognizing A. Schreber?. 
NEES, Gen. Ast. 140. 1832. 
3. Eurybia macrophylla Cass. 
E. foliis cordatis ovatisve, radicalibus subtrinervatis, caulinis in petiolum 
alatum contractis serratis scabris subtus hirtis; caule hirto rariusve glabro patulo 
corymboso, ramulis rigidis, periclinii arcté imbricati foliolis oblongo-lanceolatis obtusis. 
Variat: a. Foliis radicalibus cordato-subrotundis, caulinis inferioribus cor- 
dato-acuminatis petiolatis, superioribus cordato-ovatis amplectentibus (huc 4. cordi- 
fous Hb. Beilschm. ex Ht. Ber. ). eon rently Nees did not intend this var. a as 
the typical form of his species; when he did so intend, he frequently omitted any var. 
` a beginning with 3 ; but was not i. his typical or name-conferring form of a spe- 
cies sometimes seeming to be listed not as a first variety but as a third or fourth. — This 
present a could agree in A. orbicularis sometimes, when the cordation continues 
even through the upper es.] 
B. Foliis areren cordato-ovatis acuminatis, caulinis omnibus ovatis acumi- 
natis in basin amplexicaulem contractis. [= Small plants of 4. excelsior ? such often 
agree with this remarkable description; which involves a stem without a cordate leaf. 
Large plants of 4. excelsior, like other Macrophyllan species, have some cordation in 
a few basal leaves. ] 
y. Caule glabro, foliis caulinis plerisque cordatis longe egens laxiusculis 
minus hirtis, summis ellipticis argute serratis basi attenuatis, corymbo terminali depau- 
perato, ramis bi-unifloris. In umbrosis rupestribus Cove Valley, AIS Aster 
corymbosus Fl. Pennsylv. in Herb. Giinth.* 
* The ** Flora Pennsylvanica’’ was contained in the herbarium of Güntherat Bres- 
lau and in the Royal Herbarium at Berlin. Günther was an author of a Flora of Sil- 
esia, 1824 ; and was ** Medicinal Assessor ” at Breslau, where he died, 1833, aged 64. 
his ** Flora xiv eae was often cited by Nees for his Aste gt species 
collected ** in the woods of Tuscarora,” ‘‘ along hedges in Cove eap “in swamps 
of Lower Cove,” « eind along Cove Cr.,’’ ** in Pennsylvanian thickets,’’ or as in our 
example above, ** growing on shaded rocks in Cove Valley." The specimens seem to 
have been collected in part by Póppig, in part by Günther himself aud perhaps in part 
also by Bernhardi, who at least contributed specimens. 
* Cove Valley” and **the woods of Tuscarora’’ seem to take us to Perry C 
Susquehanna just above the village of Marysville, and the Tuscarora Mts., the next 
long parallel range to the north, below which stretches for 30 miles or more the Tus- 
carora Valley, watered by Tuscarora Cr. forming the west half of Juniata Co., x 
now threaded by the Tuscarora Valley branch of the Pennsylvania R. R.

collected. Perhaps it was here that the original specimen of 4. glomeratus had i
