tion that Persoon had only one mrs plies As a matter of 
fact, he has two—nos. 17 and 28—on the same page; the former 
based on Galega villosa of Michaux, the ites on G. villosa Linn. 
lt is fortunate that those ——— botanists who regard the earlier 
precedence of a name on the of a book as a claim to priority 
are in this case prevented from zeae T. villosa, no. 17, by their 
rule as to the adoption of the earliest specific designation. T. villosa 
Pers. will therefore remain attached to the Old World plant.

II. Cracca HOLOSERICEA, 
The identity of Cracca virginiana L. having been established, it 
completely has its identity been lost sight of, is Tephrosia holusericea 
Nuttall, which was proposed by him as a species in 1884, and was 
* Cited as of Curtis by Miss Vail and Dr. Robinson, but the context shows 
that the “‘N” after the name = Nuttall.
