PRIORITY OF PLANT NAMES. 163 
PRIORITY OF NEGUNDO. 
Acer Negundo Linn. has been regarded by some authors 
as sufficiently different from the Maples to constitute the 
type of a separate genus. As such it had been called Negundo 
aceroides by Moench, in 1794*, until it was found that the 
older name Rulac Adanson, 1763?, was to be applied. The 
species was called Rulac Negundo (Linn.) in later works.’ 
Negundo as a genus name given to the plant before Lin- 
naeus is, however, the oldest post-Linnaean name as well; for 
Boehmer restored it in his edition of Ludwig’s Definitiones 
Plantarum Generum in 1760 thus antedating Adanson’s 
name by several years.

ABUTILON AVICENNAE. 
In the seventh edition of Gray's Manual the name of the 
plant hitherto called Abutilon avicennae Gaertner, has been 
changed to that of Abutilon Theophrasti Medikus. The form- 
er name seems to have priority in its favor, and the binary, 
Abutilon avicennae was applied by Grotjan* in 1759. The 
work of Medikus on the Malvaceae was published in 1787, and 
Grotjan's binary was used before any work was recorded of 
Medikus. Accordingly for those who do not countenance du- 
plicate binaries like Abutilon Abutilon; which the Vienna Con-
