﻿Other points to which the author draws attention as not having 

 heretofore received sufficient notice are — the form of the innermost 

 root-leaves, and the comparison between the base or foot of the 

 involueral hairs, and the usually finer and clearer extremity; 

 these two parts of the hairs are denoted in the descriptions of 

 the plant as the "Fusztheil" (foot-part) and the " Spitztheil" 

 (point-part). The quality of these " Spitztheile " is held to be of 

 great importance in the arrangement of species. Several other 

 new botanical terms for the clearer designation of the characters 

 of Hieraeia have been introduced, and we could wish that Dr. 

 Efstrand had given us equivalent English or Latin terms. The 

 " Hullbreite," as the name implies, is the breadth of the involucre, 

 and is to be taken within the apparently non-persistent or dying 

 phyllaries, if such are present (see note 1, page 3). 



A footnote on page 3 tells us that in some species of Alpina 

 f/enuintt, viz., alvn 



numerous, outer non-persistent phyllaries are of nearly equal 

 height, and form an " Aussenhulle " (outer involucre), a charac- 

 teristic not observable in dried specimens. 



As will have been already inferred, the work is in German. Its 

 seventy-one pages and three charts not only afford a useful contri- 

 bution to the literature of that section of Hieracium of which they 

 specially treat, but contain hints on classification and description, 

 many of which may with advantage be adopted when dealing with 

 other portions of the genus. Frederick J. Hanbury.
