594 BARNHART: DATES OF THE NovA GENERA OF 
in the “ addenda et corrigenda,”’ read originally as follows: “ Pars 
hujus operis, quae de Compositarum familia tractat ; jam ante tres 
fere annos a me finita, illo tempore, a clarissimo Henrico Cassini, 
leviter quidem, ob magnam specierum et generum copiam inspecta 
est. Quo factum est, ut nomina et characteres generum nos- 
trorum novorum non retinens, Ampherephis speciei tertiae, in her- 
bario illustr. Jussieu asservatae, tanquam distincto generi, nomen 
Centhratheri imponeret.’’ Immediately and indignantly did Cas- 
sini resent this implied reflection upon his honor, and brand it as 
a falsehood ; and although Kunth maintained that no offense had 
been intended by the original staement, the objectional paragraph 
was modified until, as finally presented to the subscribers to the 
“Nova genera,” it took this harmless form: ‘Pars hujus operis 
quae de Compositarum familia agit, jam exeunte anno 1815 a me 
ad finem perducta, nonnisi mense septembre 1817 typis describi 
coepta est, absoluta eodem mense 1818, vulgata 1820. Interea 
celeberrimus Cassinius, observationum mearum inscius, Compost 
tas summa diligentia raraque sagacitate scrutari continuavit sectio- 
nesque et genera proponere: quo factum est, ut eorum complura 
diversis nominibus a Cassinio et me nuncupata exstent; quod 
semper usu veniet, quotiescunque duo in plantas examinandas 
aeque exercitati botanici eandem familiam investigant generaque 
ea instituere necesse judicant et instituunt. Ampherephis specie 
duas in herbario Humboldtiano observavi, tertiam in herbario Jus- 
siaeano, cui nomen a me inventum tunc stylo cerussato adscribere 
haud neglexi, Celeberrimus Cassinius vero non animadverten®, 
opinor, id nomen ibi jam a me appositum esse, plantae Jussiaeanae 
nomen Centratheri imposuit.”’ 
Those wishing to learn further particulars of this controversy 
should consult the papers by Cassini and Kunth, published ” 
volume 89 of the “ Journal de physique, de chimie et d'histoire 
naturelle ;” * and those who do not acknowledge that the volume 
was published until issued in parts in 1820, should not overlook
