flowering plants, ferns, and horsetails, with the London catalogue 
of British plants, Part I., as our guide. This useful little book 
aims at giving a fairly accurate list of plants. The last edition, 
the eighth, is dated 1886, and the editor is Mr. F. Hanbury. It 
is based on the ‘‘ Genera Plantarum,” a great work completed only 
afew years ago. The first edition was issued in 1844, and the list 
has gone on lengthening. Edition seven, published in 1874, 
reaches 1665 flowering plants, ferns, and horsetails ; but the eighth 
edition gives 1821, besides many varieties—an increase of 156. 
To account for this increase, and get much information as well, 
read the “‘ Explanations ” of the editor. I have ticked off as actually 
found about 698 species and varieties. Taking some of the 
strongest natural orders, as far as British plants are concerned, I 
am able to give the following statement, which may be fairly 
correct. The plants, as to their habitat, may be classed as ‘“ chalk,” 
‘fluviatile,” ‘‘ sylvan,” ‘‘ bog,” and “ marine.” Such as occur on 
the top of the Downs are only dwarfed forms of plants that grow at 
a lower level :—

as the case may be, have their value to the student. Some of the 
returns are good, as, for instance, the 62 out of 169, the 60 out of 
135, and especially the 51 out of 87. In several cases nearly half 
the British species are with us, in others a much smaller propor- 
tion. The 23 Rosaceous plants out of 129 are explainable, for the 
one genus Rubus (Blackberry) is credited in the London Catalogue
