[E. rosewm] had long previously been raised artificially, though 
none of the cine prveno seems to have been aware of the 
fact. Sir James E. Smith, in 1800, had remarked concerning 
Epilobium roseum: ‘Is it mouths it may have originated from seeds 
of the latter [#. post getsree! impregnated by the ‘pollen of E. mon- 
tanum ?’ [Engl. Bot. x. t. 693). In order to test this suggestion 
Dr. Bell-Salter, about the year 1842, fertilized H. tetragonum with 
pollen of H. montanum; seeds were readily produced, and hybrids 
obtained, which Megs a as intermediate between the parents, 
but different from F. resewn. He then reversed the cross, but the 
progeny Sahel indistinguicheble, These hybrids were raised true

admirable paper on ‘“ Plant Aabeisaionn of the Tay Basin,”’ by the 
late Robert Smith, of whom we hope to say more later ; it is

Tue second instalment of Das Piette contains the T'yphacee 
and Boar ganiacea, by Dr. P. Grae 
We have received the first ae ‘a what seems likely to be an 
important work on Cactacew—Bliihende Kakteen—which Mr. Neu-

plates—those in the present number are excellent—at the cost 
of four marks. The book will. be useful both to botanists and 
horticulturists. 
Tue Botanical Department of the British Museum has — 
M. Bescherelle’s herbarium of exotic Musci and Hepatice 
It consists of 14,800 specimens of Musci and 3500 specimens of 
Hepatic. It contains the types of the many species describe 
Bescherelle, and a large number of specimens collected in the 
French Colonies seduce the last thirty years, = well as collections 
made in the islands of Amsterdam and St. Paul, in Brazil, Para- 
guay, Tahiti, Japan, Mexico, and the Marquise Islands, which 
were described by Bescherelle. There are also numerous authentic 
specimens from older workers, such as Schimper and Montagne, 
and from the older French explorers, such as Beret! de St. Vincent, 
D’Orbigny, D’Urville, and Du Petit Thouars
