cific name was (of course unwarrantably) coined at the same 
time for this plant, namely, can-a-den'-sis, so that in American 
Manuals (except recent ones) the name of this tree stands as 
Gym-noc-la-dus can-a-den'-sis Lam. (1869). But Koch restored 
the specific name originally applied by Linnaeus, and hence the 
botanical name of the Kentucky Coffee tree is followed by a 
double citation of authors and thus stands in print: Gym-noc'- 
la-dus di-oi'-ca (L.) Koch. An example from Mycological lit¬ 
erature is as follows: The Corn-Smut is now designated as 
Us-ti-la-go ze-ae (Beckm.) Ung., and the history of the nomen¬ 
clature in this case is as follows. The Smut was called by Beck¬ 
man Ly-co-per -don ze'ae, and later Unger perceived its relation¬ 
ship to the forms included in the genus Ustilago, hence he is cred¬ 
ited with this correct combination. Ustilago maydis — so com¬ 
monly used in botanical publications is a synonym of the name 
as given correctly above. Still more complicated cases in which 
the principle of priority is concerned are those where there are 
two or three (or more) distinct spore-producing stages in the life 
cycle of the fungus. To illustrate this a common Rust on Wheat 
may be cited, namely, the species that has been generally called 
Puc-cin-i-a gram -in-is. This has its first stage (or first two 
stages) on Barberry leaves. It was originally named Ly-co- 
per-don poc-u-li-for -mis by Jacquin in 1786, but not at all under¬ 
stood, since it has no affinities with the Puffballs (Lycoperdon). 
Then in 1891 Gmelin named the Cluster-cup stage of this Rust, 
which occurs on Barberry leaves, Ae-cid'-i-um ber-ber -i-dis. 
The last stage — in which the spores are called teleutospores — 
was named Puc-cin-i-a gram-in-is by Persoon in 1797. While 
it has been the common custom to designate this by the latter 
name, strict application of the principle of priority (which is cer¬ 
tainly desirable) requires that the name be written as follows: 
Puccinia poculiformis (yfacq.) Wettst. — the latter author having 
in 1885 made this correct combination.
