stand as genuine natives. The account of the Glnnsstoeshine 
tocwig for the former (Journ. Bot. 1903, 290) is (of course unin- 
tentionally) misleading; the plant occurs in very aan quantity, 
and there are houses nearer than is there stated: while the intro- 
duction of the Sisyrinchium may renserenty be accounted for by 
note (J. ¢.) ‘now looks absolutely native,” appear in the Catalogue ? 
Salvia verticillata is perhaps as yet Ee fe established, but 
it might claim italicized admission. 
The prefix of the hai to such plants as the Poppies is a 
new feature in this edition. There is much to be said for con- 
piers the  PeDEe. 9 as woods of cultivation, but it seems strange 
e P. somniferu e same footing as the other species 
ur own 
Moreover it seems odd to brand “all the Poppies as introductions 
and to pass all the Fumitories as natives. 
It will we think be somewhat difficult to pasen the proper 
authority to some of the new combinations. When it is definitely 
stated that a genus has been undertaken by some one author, the 
matter is simple; but in other cases it is not so. For example, 
name is not cited, nor is any synonym given; similarly the two 
varieties of Betula tomentosa—* b. denudata E. S. Marshall” and 
: ee parvifoka BE. S. Marshall”—have not me: believe been pre- 
nuda there is 
betet in the introduction that Mr. A me shall revised the genus 
Betula; but in the former we presume Mr. Hanbury must — 
sponsor, and that the name would have to be quoted ‘ 
caudi Hackel ex F. J. Hanbury” if it wee regarded as eatey 
published, which we do not think is the 
We are aware, of course, that Mr. Ha: abexy does not and indeed 
cannot claim any responsibility for the aaa portion of the 
Catalogue of which he is editor. The case, although not absolutely 
analogous, has much in common with that of the Hortus Kewensis, 
the names in which are by common a cited as of Aiton, 
although it is known that he was not personally joenonehe for 
them. The cases in which the question ae are mainly 
those of varieties, and these for the most part are pat of by 
the fact that Mr. Druce’s List, in which they also occur, antedates 
the Catalogue by about a month: thus the varieties of Radicula 
Nasturtiwm-aquaticum, referred to above, will stand as of Druce. 
A correlation of the two publications will thus be necessary; but 
it will, we fear, Peet many difficulties—e.g. Betula tomentosa
