Zanoni (editio Montii) ^ Rariorum stirpium historia ex parte olim edita, 
(1742) enthült ausser nicht wenigen unaufklárbaren Pflanzen der italienischen 
Ausgabe von 1675 Ergünzungen von Montius und ist also zu berücksichtigen. 
Die Tafeln tragen noch die italienischen Namen der alten Auflage. 
Zwinger, Th. "Theatrum botanicum (1744), die von Zwinger fil. besorgte 
Neuauflage des alten Krüuterbuches vou 1696, mit Bombast herausgegeben, ist 
botanisch kritiklos, hin und wieder mit einigen Boerhaave'schen Gattungsnamen 
versehen und wohl ohne sonstige Zusátze; ich habe es nicht berücksichtigt, und 
dürfte auch kaum noch ein Name daraus verwendbar sein. 
8 16. Modern English Nomenclature. 
There is now in preparation at Kew a very important future standard book, 
the announced nomenclature of which is not always in accordance with the 
international laws of botanieal nomenclature. Before we examine the differing 
points, I have to say a few words on the book in preparation. 
The ,, Kew index of plant names by B. Daydon Jackson, Secr. L.S. 
funded by Charles Darwin, planned at first as a. continuation of Steudel's Nomen- 
clator, now in preparation since 9 years under the direction and responsibility of 
Sir Joseph Hooker, will not be now a work like Steudel's Nomenclator, but a 
faithful index of the names of phanerogams. Mr. Jackson, the excellent compiler 
and bibliographer, wrote in Britten's Journal of Botany 1887 p. 67..-: 
,Accordingly our plans were altered so as to try and give a view of the actual 
state of botany at the end of 1885, leaving it to monographers to fully settle 
questions of synonymy of doubtful species.* 
I fear, we shall get in this way only a wrong view of the actual state 
of systematical botany at the end of 1885; for plenty of synonyms or nearly 
all such species in Steudel's work which were since reduced to synonyms by 
other botanists have not been noted as synonyms in the Kew lists of that index, 
at least till spring of 1889, from which time I looked no more in these lists. 
Surely a great many synonyms will have been eliminated meanwhile out of 
the current species, but I think it should be worked up in a manner nearer 
to Steudel's. Steudel did not revise each species, but accepted only the species, 
that were not suppressed by other authors in monographs or standard books. 
That should be done also here by all means; for if we wait till mono- 
graphers work up all genera, we never will get order. But all botanists want 
in such a book a previous temporary order, as we find it in Steudel's Nomen- 
clator and as was the wish of Darwin (cfr. l. c. 1887 p. 151). Otherwise 
we would get an excellent help-buok with the references to the edition of each 
species or synonym, but fit only for monographers; a book, which notwith- 
standing will be used by other botanists and other naturalists, causing thereby 
much confusion. 
It is to be hoped that after the compilation of literature the Kew index 
lists will be checked with the Kew herbarium to bring their contents to a perfect 
agreement with Bentham and Hooker's Genera plantarum; by that means 3 
great number of species and synonyms now registered in wrong genera will fin 
their exact place, more already reduced species would be eliminated and more 
synonyms found. 
I may express a wish, which if fulfilled would make the index still more 
useful: If then all species not existing in Kew would have a printed sign OT
