PREFACE 
In the preface to the first edition of this Glossary I gave the 
reasons which induced me to undertake it, and the fact that 
the impression was exhausted some time ago, is a gratifying 
confirmation of those reasons. The delay in preparing this second 
edition has been entirely due to pressure of occupation. The 
“Additions” of the edition of 1900 are now combined with the 
terms recently published in one alphabet, for the earlier sheets 
being stereotyped prevented their incorporation. 
One special feature of the recent additions is that of the phyto- 
geographic terms coined by Mr F. E. Clements, and published in 
Engler’s “ Botanische Jahrbiicher,” xxxi. (1902), Beibl. No. 70, and 
since added to in a volume of the Nebraska University, “Studies in 
the Vegetation of the State,” iii. (1904). I felt bound to give these 
in their entirety, though in many cases I could only copy the defini- 
tions given by the author, ¢.g., the use of “creek” in the American 
sense, and in a few cases classical authority and grammar have been 
ignored. The special terms contrived for American conditions have 
not been transferred to these pages, and those who require to know 
the meaning of such compounds as “ Carex-Sieversia-Polygonum- 
coryphium,” with its vernacular equivalent “‘The Sedge-smartweed 
Alpine meadow formation,” are referred to the work above quoted. 
In the ‘ Annales des Sciences Naturelles Botanique,” Sér. VIII. xiv. 
(1901), 213-390, will be found another elaborate series of terms, 
which have not yet made their appearance in English books, and 
are consequently not embodied in the following pages. 
The task of selecting what terms should be included in any 
branch of science offers many difficulties: in the case of botany, 
it is closely linked on with zoology and general biology, with 
geology as regards fossil plants, with pharmacy, chemistry, and 
the cultivation of plants in the garden or the field. How far it 
is advisable to include terms from those overlapping sciences
