but Archam/elica is not considered British, and Petroselmum sativum 

 is labelled "subsponte." [By the way, it is to be wished tliat our 

 botanists would examine the plant of our western coasts, which it 

 is not unlikely may prove to be P. peregriniim, Lag., of Portugal 

 and North Spain.] Probably most of the above views as to 

 nativity would be endorsed by the majority of British botanists, 

 but more doubt may be felt as to Cent rem thus ruber and Aster 

 salignus, both of which are given as British natives. CEnanthe 

 fluviatiUs is one of the very few i3lants restricted to Britain ; it is, 

 however, regarded by N}Tnan only as a sub-species of (JE. Phellan- 

 drium. There are no less than 107 Euro^Dean species of Saxifraga, 

 of which 15 are British (or 16, if we add the Faroe islands, which 

 are here credited with the Greenland and Arctic American species 

 S. tricuspidata, Eottb., doubtfully given in Eostrup's list). It is 

 not quite clear how our names fit in. Britain is not given as a 

 locahty for S. hypnoides ; probably our ^Dlant is considered to be 

 S. sponhemica, Gm. S. grcenlandica (sub-species of S. decipiens) has 

 Scotland after it, as well as S. cmsjntosa. There is a similar 

 obscimty in the case of our maritime Artemisia: A. gallica and 

 A. maritima are here treated as sejparate sj)ecies; the former grows 

 in "Brit.," the latter doubtfully in "Angl.," but its sub-species 

 A. salina, Willd., is native in "Brit." 



Space will not permit of further notes, but they might be 

 indefinitely extended; e.g., a list of the 21 British Hieracia 

 (several peculiar) out of 185 European species might be given. 

 The synonymy shows evidence of very careful work. Indeed, in 

 looking through the book, one cannot help wishing that the 

 author, who has so clearly grasped the limits of his species, and 

 grouped them so excellently weU under the genera, had given us — 

 as he could better than any one else — a short diagnostic character 

 of each species and genus, and thus sui^pHed the urgent want of a 

 general European Flora. 



One accidental omission should be noted : Herniaria glabra and 

 its close allies, H. ciliata, &c., have been left out on p. 256.

The prothallia of Aneimia and Muliria, though different in 

 minor details one from the other, re^Dresent an altogether peculiar 

 tyi^e of development. In the pro-embiyo a number of rows of cells 

 are formed by longitudinal partitions, either simultaneously with 

 or anteriorly to division of its terminal cell. This growth by 

 longitudinal sej)ta has been held by Burck, who has studied the 

 l)rothallogeny of Aneimia, to be peculiar to that genus; the fact 

 being that in PoJgpodiacece and CgatJmacew such septa occur, but 

 only after division of the apical cell. In the two genera examined 

 by the authur he found that the apical cell divides longitudinally
