Beurera Ehret, Pl. et Pap. Rar. Depict. ¢. 73 (1755). 
Basteria Mill. Fig. Pl. ¢. 60 (Dec. 30, 1755). 
Calycanthus L. Syst. Ed. 10, 1066 (1759). 
There are three excellent reasons for preferring Bztineria to 
Beurera as the name of this genus: 
(1.) Ehret’s Tab. 13 was not, so far as I can learn, distributed, A 
and was certainly not included by Trew in his “ Plante Selecta. 
For this reason Seurera is not, strictly speaking, a published 
generic name. 
(2.) Biittneria should be considered as having priority over 
_ Beurera, for it seems to be impossible to ascertain the exact date 
of Ehret’s Table 13, although, as Dr. Kuntze tells us, the plate 
bears the date of the year 1755, in which it was registered. While 
admitting the apparent impossibility of ascertaining more exactly 
the date of the table, Kuntze states categorically: « Die Tafel 13 
ist aber wahrscheinlich frither als September erschienen.’* No 
word of evidence is adduced to prove this statement. Now, 
though no such rule has been formulated, it would seem that, 17 
such a case, justice to the authors of other names would demand 
that we place the date of the plate at the very end of the year 
1755. : 
In a letter from Peter Collinson to Linnzus,+ dated May 12) 
1756, this sentence occurs: “Mr. Ehret has only [just] published m 
the Beveria, being what at Paris is named Autueria.” This re- 
mark can bear but one construction, that which I have given it by ; 
inserting the word “ just.” As Collinson’s last letter to Linnaeus 
before that of May 12, 1756, is dated July 29, 1755, and contains 
allusions to Ehret’s work, but none to the « Beveria,” the proba- 
bility is great that the Table 13 was not officially entered before 
the last months of 1755. Collinson, it may be added, was in CON 
stant personal communication with Ehret at this time, and tus 
frequent letters to Linnzus evince the interest he felt in the artigt : 
work. As accurate knowledge seems impossible, even such purely 
circumstantial evidence should have some weight. Duhamel _ 
work was registered in August and published in September of the, 
same year. :
