—1804. Willdenow in Berlin may an had A. Schreberi in 
cultivation and may have intended that by his variety described* 
1804 under 4. macrophyllus as 
* 3, corollae radio albo," 
adding below that this differs from the blue-rayed (genuine lilac- 
rayed A. macrophyllus) in showing linear rays not oblong, and 
bracts oblong and obtuse; all of which distinctions point to 4. 
Schreberi. Willdenow also added that the rays are longer than the 
involucre, which was probably the special cause of Nees’ remark 
1832 that Willdenow had confused the characters of 4. 
Schrebert and A. macrophyllus badly. 
10-1818. Before 1810, the time of his death, the director 
von Schreber f of the botanical garden at Erlangen near Nurem- 
berg, had brought there the type plant of this species, from some 
unknown source. The plant does not seem to have been noticed 
by Martius, who catalogued the garden in 1814 ; but C. G. Nees ab 
Esenbeck succeeding as director of the garden in 1818, observed 
the plant, recognized it as distinct from A. macrophyllus, named it 
in honor of its first cultivator, and described it that same year as

Erlangen, 10 Dec., 1810; commemorated in the genus Schrebera Roxb. Schreber, 
celebrated Linnaean editor, had ciate in youth under Linnaeus at Upsala, had be- 
come, at 30, professor of medicine and of botany at the Univ. of Erlangen and director 
of its botanical garden in 1769. Schreber was author of botanical works, 1764-1792, 
writing, not on Asters, but on the Musci, the grasses, a Flora of Leipsic; Icones and 
descriptions of less known plants in 1766, etc. His 8th edition of Lino. Genera 
plantarum appeared at Frankfort, 1789-1791.
