systematic plan of terminology. lt will not be very troublesome to unify future action; 
but the serious conflict will come when there is a demand to make to conform to new 
rules whatever of ancient terminology conflicts with them. However, American botanists 
should encourage this movement in every way, and it would be well to consider the 
subject at their next general meeting 275). 
April 1893. Bulletin of the Torrey botanieal Club S. 174—181; Be- 
sprechung des kürzlich erschienenen (mir noch unbekannten) Werkes von Conway 
MacMillan, Metaspermae of the Minnescta Valley 826 Seiten (cfr. S. CCCII) 
Ich eitire hier nur die auf Nomenclatur bezüglichen Stellen aus der Besprechung. 
In his preface the author expresses satisfaction at the action of the Botanieal Club of 
the A. A. A. S, taken at the Rochester meeting of 1892, in its endeavor to establish nomen- 
clature "upon some other than a personal basis," and states that the initial date, 1753, would 
have been adopted by him, for genera as well as species, in this work, had not most of it 
been in type when the Club's action was taken. In order to comply with those prineiple, ho- 
wever, the following list is inserted for the convenience of those who may wish to note the 
necessary changes: 
Mariscus, Hall. (1742) — Cladiwm, P. Br. 
Craceca, Liun. (1747) —  Colonilla, Adans. 
(1756). (1763). 
Cyperella, Cram. (1744) — Juncodes, Adans. Ricinocarpus, Burm. (1737) —  Aealypha, 
(1763). ] Linn. (1753). 
ih E (747) e Boehmeria, Jaeq. | gy pisi -Ludw. (1787) e Callitriche, Linn. 
uillularid. Linn. (1748) — Stellaria, Linn. (1753). 
(1753). Lappula, Hall. (1745) —  Lappula, Moench 
(1794). 
Leptostachya, Miteh. (1748) — Phrymaà, Linn. 
Leuconymphaea , Ludw. (1737) —  Castalia 
Salisb. (1805). 
? 
JNymphaea, Ludw. (1737) - —Nymphaea, (1753). 
Salisb. (1805). ] Pentagonia, Sieg. (1737) —  Legouzia, Dur. 
Capnorchis, Ludw. (1737) —  Bikukulla, (1782) 276) 
Adans. (1763). 
The rule whieh excepts duplicate binomials, as Phragmites Phragmites (Linn.) form 
the law of priority, is also gracefully accepted, and wherever such binomials are found in the 
work the request is made that the second oldest specific name be used, although the author 
was not and is not now in sympathy with any such exception. 'The above binomial would 
thus become Phragmites vulgaris (Lam.). 
?'5) Obwohl diese Regelung der biologischen Terminologie bisher den 
Pariser Codex nieht berührt, so habe ich doch den Artikel wieder gegeben, 
weil daraus hervorgeht, wie das Streben nach internationaler Harmonie in der 
Botanik auch in anderen Zweigen wüchst. Unsere deutschen botanischen Physio- 
logen sind in aller Welt verrufen wegen ihrer rücksichtslosen Wortbereicherungen 
ohne Rücksicht auf internationales Verstándniss; namentlich die Englünder 
haben sich schon ófter darüber bitter beklagt. 
Vielleicht findet spüter diese Regelung nachtrügliche Aufnahme in den 
Pariser Codex emendatus. 
?*6) Prof. MaeMillan, who, as that list clearly shows, had adopted all 
my renewed names, beginning with 1737, has altered only few of my inserted 
names afterwards by turning to 1758; but Cracca, as already the editor of the 
Bulletin noticed, appears in Linnaeus sp. pl. 1753; of Nymphaea of 1758 
with 4 species belong 2 to , Castalia^ (1 to Nymphosanthus Rich. May 1808 
then to be taken for Nymphaea ,Salisb.* — Nuphar Sm. 1808/9; and 1 to 
Nelumbo Ad.) so that Nymphaea L. p. p. !/5 should stand for Castalia ; Peta- 
gonia Sieg, 18? cannot get Legouzia Dur. 1782, because Specularia. Heister 
has been taken up therefor by Fabricius 1763 (perhaps also 1759) in his 
Enum. pl. horti helmst. p. 226.
