Arrera moderate delay the third, and so far the largest part, of 
this new British flora appeared about the last month of last es : 
it consists of a hundred pages, in addition to three pages of e 
planatory matter on the cover, and after finishing the genus Cr va 
(C. succisifolia and C. cones! is devoted to ‘‘a revision of the 
eracia.”’ In attempting this revision Mr. Williams has 
found it necessary to vel through a large series of the forms 
occurring in Scandinavia, Central Europe, and France; 
troductory remarks he instances some of the salient characters 
applicable to the genus, as follows :—Glandular hairs are in certain 
almost concealed by them. In another group the glandular hairs 
are collected mainly at ot base of the Mia and on the 
secondary pedicels, a few the stem, and n n the leaves. 
In other groups the sianiilar hairs are less un aaually proportioned 
to the simple hairs on the secondary pedicels, and absent from the 
upper part of the stem and from the leaves, or, as in the Alpina 
section, glandular hairs exist on the leaves, though sometimes only 
in small quantity. Another character, which the author considers. 
selinadity important, and which he says has been entirely over- 
looked, deals with the structure of the alveolar elapsed a the 
receptacle; this character aa he the sections Oerinthoidea 
and Oreadea from the section Vulgata. ‘ Aastha ttt 
character is to be found in the stem-branching. In those species 
ite 
arrangement obtains in different groups. In one group the furea- 
tion is determinate, in another it is indeterminate with the branches 
alternate. In polycephalous forms, such as the common H. sil- 
vaticum Gouan, of the woods and on the rocks of hilly districts, the 
primary branching is botryose, and the secondary and terminal 
branches determinate, cymose, or sometimes pleiochasial or even 
umbellate. In descriptions this branching has been often loosely 
given as paniculate or corymbose, which eepreyt little information.
