220 BOTANICAL NEWS. 
which contains a chapter on the fungi of Ferns, to which we would call special 
attention. 
The Bulletin of the Botanical Society of France sajs that the International 
Botanical Congress, which will be held in Paris in August next, will derive 
great advantage from the pacific state of Europe, and probably have the benefit 
of the presence of M. Alphonse De Candolle, who is to draw up a programme, in 
which the different contested points as to the nomenclature of plants, etc., will 
be put down for discussion. It also remarks that some fine collections of fossil 
plants and other objects of high botanical interest will be exhibited. 
From the report of Drs. Anderson and Cleghorn we learn that the Mahogany- 
tree thrives well in India, and that its cultivation might be profitably extended. 
Mr. Charles Moore, the Director of the Sydney Botanic Garden, and Mr. 
M'lvor, the Director of the Ootacamond Botanic Garden, are now on a visit 
to this country. 
Dr. Milde's ' Monographia Equisetorum,' in which he has been engaged for 
so many years, has at last appeared. It fills an entire quarto volume of the 
Nova Acta of the Imperial German Academy Naturae Curiosorum, and gives 
plates of every known species of Horsetail, embracing the most minute struc- 
tural details. He reduces the entire number of species to 25, distributed over 
the whole globe, with the exception of the Australian Continent. 
Our last year's obituary should have included the name of Baron von Sie- 
bold, Doctor and Colonel in the Dutch service, who died on the 18th of Octo- 
ber at Munich, and to whom we are indebted for much of our present know- 
ledge of the Japan Flora. Siebold was born at Wiirzburg, and was 71 years 
old when he died, after a short illness. Up to the last he was busy with ar- 
ranging his extensive Japan ethnological collections for public exhibition.— 
Julius von Warszewicz is another botanist whose death we have to deplore. 
Warszewicz was a Lithuanian by birth, and educated at Wilna. Having been 
compromised in the Polish revolution of 1831, he emigrated to Prussia, where 
he became acquainted with Humboldt, who recommended him to the Belgian 
Acclimatization Society, in whose service, as well as that of M. Van Houtte, he 
explored several parts of Central America. Earning to Europe in 1850, he 
made shortly afterwards another journey to Central America on his own ac- 
count, from which he returned in 1853, collecting and introducing during this 
time many rare and new plants. In 1854 he was appointed Inspector of the 
Botanic Garden of Cracow, which appointment he held with credit to himself 
and advantage to the garden, till on the 29th of December death cut short his 
career. Warszewicz attained but 56 years of age. He was hard of hearing, 
and spoke all European languages, except Polish, most imperfectly, which was 
probably the reason why he has written so very little. His name has been 
given to genera and species, and will always be gratefully remembered. 
Quekett Miceoscopical Club.— The monthly meeting of this club was 
held at University College, on June 28th, Mr. Ernest Hart, president, in the 
chair. A paper was read by Dr. Robert Braithwaite on " The Organization of 
Mosses."
