286 Notices respecting New Books. 



inundatum {Hydrocotyle inundata of Fl. Br.) and verticilla- 

 tum are removed to Skim, and Phellandrium aquaticum to 

 CEnanthe. The genus Mcum, it appears, has no floral receptacle, 

 and furnishes a reason why the Common Fennel (Anethum 

 Fcenicuhtm), and the Spignel, which has been an Athamanta of 

 some authors and an JEtfmsa of others, and which is allied to 

 the Fennel in habit, should be united. Peucedanum Silaus, di- 

 stinguishable by its floral i - eceptacle and its fruit, is now a 

 Cnidium. Most of these changes, inconvenient as they are to 

 present science, are warranted by the opinion of some of the 

 best foreign botanists ; and Sprengel, who did not adopt the 

 part of fructification here introduced, but relied chiefly on 

 the seeds, was led to similar conclusions. 



The Linnaean genus Jimcas is entirely remodelled, and the 

 author, following some other botanists, has separated the 

 "grass-leaved" species of the old herbalists, which have but 

 three seeds, and are quite distinct in habit, from the true Junci. 

 Juncus arcticus and polycephalus are new Scotch species from 

 Professor Hooker's " Flora Scotica." The name of J", bulbosus, 

 inappropriately applied by Linnaeus, under a mistake, to the 

 species bearing that name, is divided into compressus and coz- 

 nosus. J. gracilis of former English botanists is here called Ges- 

 neri, the trivial name of gracilis having been appropriated be- 

 fore by Mr. Brown to another species. J. subverticillatus, a 

 species quite distinct from uliginosus, and long taken up by the 

 continental botanists, is added. J. supinus of Don is, in the 

 opinion of the author, only a starved variety of his idiginosits ,• 

 but the plant noticed by some others, found by Hudson in 

 Jersey, and first published by Mr. Symons in his useful Syn- 

 opsis, he discovers to be the true capitatus of foreign authors, 

 a change in which we entirely concur. The alteration of the 

 name of the new genus from Luzida, which had been already 

 adopted, to Luciola, was hardly warranted upon any classical 

 scruples, especially as Jussieu has a genus of Grasses which he 

 calls Luziola. The crest of the seed furnishes a sure criterion for 

 distinguishing some of the most difficult species. The L. cam- 

 pestris /3 is, perhaps, rightly raised to a species under the name 

 of congesta, which had been adopted in Forster's "Flora Ton- 

 bridgensis." L. arcuata is enth - elynew to our Flora, having 

 been found by the indefatigable Glasgow Professor on the 

 Grampian Mountains, and recently published in the continua- 

 tion of the " Flora Londinensis." 



The Rumex digynus affords the type of a new genus, which 

 Mr. Brown has established under the title of Oocyria, a name, 

 curious to relate, coined by the redoubtable knight Sir John 

 Hill ; but, as the Swedish proverb here quoted remarks, 



" Sometimes
