Prunus Cerasus, Hypocheris radicata, Myosotis sylvatica ?, Origanum 
vulgare, Callitriche platycarpa, and Carex panicea,—all likely species 
to occur; have they become extinct since 1861? Atriplex Babing- 
tonii is generally a seashore plant, said to be found at Roxeth in the 
ora. 
Though there are signs of the juvenile authorship of the book, yet 
it is remarkably free from improbabilities or obvious errors; it has 
doubtless had the benefit of Mr. Hind’s supervision ; indeed his 
assistance is acknowledged in the preface, and his initials appear on 
nearly every page. 
Though a part of the district, the neighbourhood of Stanmore and 
Edgware seems to have less attention paid to it than the country nearer 
Harrow ; a good list of plants might be easily given for that part, in- 
cluding species not enumerated in the Flora. Is Primula elatior, 
found near Harrow and Pinner and in Bentley Priory, anything more 
than a hybrid form? 
There are notices of the birds of the district and a copious entomolo- 
gical list with the Flora. The book is well printed and got up, and 
is, on the whole, most creditable to the school. 
Diagnoses d’ Espèces nouvelles ou méconnues, pour servir de Matériaux 
à une Flore réformée de la France et des contrées voisines. Par 
Alexis Jordan. Tome premier, premitre partie. Paris: F. Savy, 
1864. 
Monsieur Jordan is far too well known as a botanist to need any in- 
troduction to our readers. He is the founder of a school of writers on 
species-botany, of which the leading article of faith is that a large 
number of the plants which have been taken by all authors, from the 
time of Linnzeus downwards, for single species, are in reality made up 
of a number of, it may be very closely resembling, permanent forms. 
To these, they say, permanence of character being the sole practical 
test we have of what constitutes a species, we cannot, upon any prin- 
ciple of consistency, refuse that rank and title; and to the seeking out 
and definition of these M. Jordan has, as the botanical work of his life, 
devoted himself. It is now nearly a quarter of a century since his first 
writings were published. "The book of which the title stands at the 
head of our notice is merely the first instalment of a work which is
