120 AMERICAN MIDLAND NATURALIST 
Following the lead of Linnzeus, earlier and later botanists have 
suppressed the name which for the reason of priority ought to be 
used according to the codes. 
In much the same condition do we find the names Salvia 
africana coerulea and Salvia africana lutea, one of the words being 
dropped in each case. Linnzeus himself changed both names com- 
pletely, calling the Salvia africana caerulea of the first edition, Salvia 
africana, and the other became Salvia aurea in the second edition. 
It can not fail to surprise many of the younger botanists of the 
present that those two or three generations next succeeding Linnaeus 
held the opinion that no name that was unsuitable was to be made 
permanent; that changes and improvement were to be made in the 
specific terms of binary names, when scientific truth and accuracy, 
or the call for brevity demanded ; and that they were to be changed, 
amended, or entirely displaced, as freely as any other kind of error. 
Linnzeus himself, as we have ‘said, gave his own example to the 
same effect, when in the second edition of his Species Plantarum 
the earlier 4pocynum folits androsaemi was retired by him in favor 
of Apocynum androsaemifolium. ‘The principal changes of his are 
the following : 
FrIrRst EDITION. SECOND EDITION. 
Amaryllis Bella donna, A. Belladonna. 
Apocynum foliis androsaemi, A. androsaemifolium. 
Atropa Belladonna, A. Belladonna. 
Hemerocallis Lilio Asphodelus, H. flava. 
Lonicera Peri Clymenum, L. Periclymenum. 
Mussaenda fructu frondoso, M. frondosa. 
Panicum Crus galli (?), P. Crusgalli. 
Prunus Lauro Cerasus, P. Lauro-Cerasus. 
Robinia Pseudo Acacia, R. Pseud-Acacia. 
Salvia africana caerulea, Ss. aimeana: 
Salvia africana lutea, S. aurea. 
Solanum Pseudo Capsicum, S. Pseudocapsicum. 
Trifolium Melilotuscorniculata, ‘Trigonella corniculata. 
A rather striking case of the use of hyphens in order to make 
an otherwise impossible combination acceptable to the codes and 
manual makers, is that of the Linnean Arbutus Uva urst and Vace- 
cintume Vitis idaea. Moench restored these plants to the older pre- 
Linnean genera, Uva ursiand Vitis idaea, both two-worded generic
