modern enumerations, and one of them is transferred to another 
genus. Mr. Backhouse does not admit the claims of either H. 
dubium or H. Auricula to be regarded as British plants; and the 
other, H. paludosum, is of course omitted ou other grounds. 
The genuine British Hieracia noticed by Hudson, deducting the 
three above-mentioned species, are just five, viz. H. Piloselia, H. 
alpinum, H. murorum, H. sabaudum, and H. umbellatum. In 
1796, thirty years after the publication of the first edition of 
the ‘Flora Anglica,’ Withering, in his ‘ Botanical Arrangement 
of the British Plants,’ adds four species to Hudson’s enumera- 
tion, viz. H. prenanthoides, H. sylvaticum, H. villosum, and H. 
molle. He notices also a doubtful or hybrid species, which he 
“. ealls H. Taraxvaci. Thus before the close of the last century 
“we had nine species. In Smith’s ‘Compendium Flore Bri- 
“tannice,’ published in 1818, there are fifteen species described, 
or eighteen including the rejected species above stated. In 1829 
these were increased to nineteen in the ‘ English Flora.’ In Mr. 
Babington’s Manual there are twenty-one species described ; we 
quote from the second edition. 
From the above brief statement our readers will perceive that 
the number of species in this genus has been regularly and 
steadily increasing for a century. But it is not to be inferred 
from this abstract of the progress of increase in the Hieracia, 
that we expect it to continue. It is true that Mr. Backhouse, 
hike a genuine disciple of nature, admits that the “task is not 
done,” that it is possible that some of his species may not stand 
the test of future investigation, and that some of his forms or 
varieties may be found entitled to rank as species. It is proba- 
ble that there will be no great addition, nor any considerable 
diminution of the number established by the persevering and 
zealous author of the Monograph before us. We must refer our 
readers, both for the plan and execution, to the work itself, - 
assuring them that we can honestly recommend it to their no- 
tice as a very meritorious contribution to science. Its author is 
too well known for his devotion to botanical explorations and 
successful results to need any commendation to the readers of 
the ‘ Phytologist.’ 
Our readers are aware that Mr. Baker, who is honourably 
mentioned in this Monograph, has already contributed several 
articles on the Teesdale Hieracia, and to one of them, viz. that
