THE CLASSIFICATION OF FLOWERING PLANTS 245 
kin There is an interesting note (p. 308) on the accidental 
a 7 ge of Galium Cruciata by the throwing away of the con- 
tents of a vasculum, among which was this plant. Viola Reichen- 
Seka appears to be absent ; there are not many Rubi; and the 
representation of Hieraciwm by H. Pilosella, H. rulgatum, and H. 
boreale reminds one of the good old orthodox times, before the days 
of the hieraciarchs. The Cryptogams _receiv attention,

In these days, a Santttans from the German (generally 
appearing five years too late), and text- ee written by examiners 
for examinees, represent almost the whole output in text-books of 
British botany, it is pleasant to weleome a work of first-rate import- 
ance which belongs to neither of these classes. It may be at once

characters, whether derived pt om anatomical, biological, or sys- 
tematic considerations. The of treatment reminds one of that 
followed in the Naturlichen Pjanenfention ugh, of course, it 
is not so ambitious. The generic characters are sometimes given 
in sufficient detail for distinguishing the genera, but in other cas 
and especially in Orchidaceae, this is not the case. The descriptions 
of germination are generally excellent, but other points, such a 
geographical aki a biology, and economic uses, are a ite

these, even of the economic uses of monocotyledons, a “hall
