ASTER AMBIGUUS 295 
Gray added that he himself classed the specimen as a “form 
of A. macrophyllus” — to which species he had long before united 
A, Schreberi and its allies. 
By such a long series of steps, through life in Pennsylvania, 
Erfurt and Breslau, and through the hands of Bernhardi, Nees, 
Hohenacker, Klatt and Gray, descended this single frail specimen ; 
a specimen which fortunately proves what it was which Bernhardi 
denominated A. ambiguus, and which by its coincidence of char- 
acters establishes the identity of a widely distributed ally of A. 
Schrebert which had long been clamoring in my herbarium for a 
name. 
54. Aster subcymosus Bernhardi in Nees. 
Plants with leaves broader in the middle, very fine-textured 
thin and smooth, with sharp curvescent or aquiline teeth, suddenly 
slender-acuminate, cordate-ovate ; with heads about 55, in. high.

Schreberi, A. esca and, with umbel-like apa ie in A. umbelliformis) ; fide

Stem terete, glabrate, greenish-brown, often 2 ft. high, some- 
times 3. Radicals ovate-orbicular, thinner than in A. Schredert, 
smooth except toward the margin, sometimes 8 by 4 or 5 inches. 
Caulines more long-acuminate, abruptly so ; sinus less rectangular, 
broad and shallow, and then broad and elegantly recurved, then 
obsolescent, next leaves (upper caulines) truncate and the next 
rounded-tapering, all having long slender petioles.
