28 NOTICES OF BOOKS. 



of corrections, additions, &c. A full index, with a separate one of 

 Danish names, completes the book. Its arrangement is a strange 

 one to British botanists, commencing with the EquisetdcecB and 

 ending with the Pupilionacem. Dr. Lange's estimate of the flora is 

 1415 species (with about 800 varieties). 



Looking through the Flora in the sequence followed by the 

 author, the following notes especially refer to our British Flora : — 

 Stnithiopteris (jcnnanica Willd., a fern that occurs in several stations 

 in the range of the Flora, is not known as a British species. Agw- 

 jii/rum strictum and obtnsiusciihini are two grasses that ought to be 

 sought on our coasts ; the first is suggested elsewhere to be a 

 hybrid between jniiceum (or acutiim) and Kh/nius arenarius. Bracluj- 

 jiudiioii i/racilc Beauv. is used instead of B. sijlvaticum K. et S. 

 A suggestive name is '' Lolium teviulentum L., var. speciosum Koch" 

 (L. arvense With.). Most British botanists have been in the habit 

 of quoting a plant as a variety under the name of the author, who 

 used it as a species in a parenthesis ; in this case, thus, "v. arcense 

 (AVitli.)," the advantage attending this is, it at once points out the 

 plant intended, whereas he would be a bold botanist who could say 

 he had searched out the earhest varietal name, and verified it as 

 the same plant ; herein lies the diificuHy. 



No reference is made to the suggested hybrid origin of Fsamvia 

 baltica, and the Norfolk locality on our coasts w^ould almost seem to 

 deny the probabiuty of such an origin, unless one of the supposed 

 parents had died out. Scirpus hifulim Wallr. is separated from S. 

 riifus Schrad. (Blysnnis ruj'us) as a subspecies. Mr. Griffith has 

 gathered this on the Welsh coast, but it seems hardly more than a 

 variety ; it is figured in ' Flora Danica,' t. 2703. 



A note on the various opinions of the status of Carex Bocnniny- 

 hauseniana is interesting. A question of name is involved under 

 Carex stricta Good., which name must certainly fall : the Americcin 

 C. stricta Lamarck {^fide Mr. L. H. Bailey, U. S.), is a prior name to 

 Goodenough's. Dr. Syme mentions this in ' English Botany,' but 

 did not propose any name for it ; the writer of our next Flora must 

 do something with Goodenough's plant. I would suggest Hudsonil 

 or Smithii, Porter's C. Smithii being C. triceps Michx. The mention 

 of Mr. Bailey's name may prepare our botanists for some rather 

 startling changes of Carex names, the result of his inspection of the 

 original specimens of several authors in various European herbaria. 



Dr. Lange identifies Carex piluHfera var. Leesii Kidley, with his 

 var. lowjibracteata, ' Flora Danica.' t. 3050 ; this was indicated in 

 the ' Scottish Naturalist ' a year or so ago. Five forms are given of 

 Alisma Plantayo. Junrus diff'usus has the synonym '^ efuso-(j'.aucus 

 Schnitzl." given for it. The absence of Juncus acutus and Lxizula 

 Forsteri marks the want in the Danish flora of some of our southern 

 forms. The name of Potamofjetim coloratns Horn. Fl. Danica, 

 t. 1-449 (1818), (erroneously given as 1823), must be adopted for 

 the species we now call P. plantajineus Ducroz (1827) ; there is no 

 question of the plants being the same, as Dr. Lange points out in 

 his • Nomencl. Flora Danica,' 1887. P. rufescens Schrad. is in the 

 same category, but what name it must bear is not easv to decide.
