398 FABRICIUS' ' ENUMERATIO PLANTARUM HORTI HELMSTADIENSIS. 



Flora. But the name SpecuJuria appears in Fabricius, ed. 1, 121, 

 with synonymy, and with diagnosis in ed. 2, 225 : tlie synonymy 

 therefore stands : 



Specularia Heist, ex Fabr. Enum. PL Hort. Helmst. ed. 1, 

 121 (1759), ed. 2, 225 (1768). 



Legousia Diir. Fl. Boiirgogne, i. 37 (1782). 



Under Leijiiuzia Dr. Britton gives three new combinations 

 which will have at once to be relegated to that limbo of unnecessary 

 nomenclature already so largely peopled by transatlantic creations. 

 Mr. Druce (Fl. Beri^s. 328), who had previously called attention 

 to the genus,* gives Legousia Durandi Delarbre (1800) as the 

 name under this genus for Campanula Speculum L. ; but this can in 

 no case be maintained, for Durandi is neither the oldest specific 

 name nor the earliest under the genus, that being L. arvensis Dur. 

 (1782), which is rightly adopted by S. F. Gray. The name of our 

 British plant will remain Specularia hyhrida A. DC, as it stands 

 now in the London Catalogue. 



By the help of Fabricius, the absurd name Gouringia, which, 

 owing to Adanson's misprint, has been establishing itself in our 

 lists, may entirely disappear : it stands as Conringia in Fabr. 

 Enumeratio, ed. 1, 160 (1759). This happily disposes of Mr. 

 Druce's note on the genus (Fl. Berks. 58) : the two new synonyms 

 which he (/. c.) proposes for C. austriaca Sweet, an exotic species 

 "found on waste ground," may join Dr. Britton's names under 

 Legousia. 



Among the names not in the Index Kewensis is Umhilicaria 

 Heist, ex Fabricius, op. cit. ed. 1, 42 (1759), ed. 2, 76 (1763), 

 which must replace Omphalodes Moench. Meth. 419 (1794). Both 

 genera are based upon the same two Linnean species, which are 

 indicated by their Linnean numbers and diagnoses in the second 

 edition of Fabricius. This raises an interesting point as to whether 

 such indication by number will be considered as entitling Fabricius 

 to be considered the author of the names Umhilicaria linifolia 

 and U. Omphalodes, which these two species should take. The 

 genus of lichens bearing the same name is of much later date 

 (1789), and will have to be abandoned by those who object to a 

 similar name being employed in phanerogams and in cryptogams. 



Another instance of a name which seems to have been entirely 

 overlooked — it is neither in the Index Kewensis, nor in Pfeiffer's 

 Nomenclator, nor in any of the books cited above — may be found in 

 Sphmrocarpiis, the earliest name for the genus which American 

 botanists retain as Neslia, and for which Mr. Druce (Fl. Berks. 69+) 

 revives Medik's Vogelia (1792). Exception may be taken to the 

 adoption of the name SpJmrocarjms on the ground that Adanson 

 used it in the same year for a genus of cryptogams — whether 

 earlier in the year 1 do not know. I am inclined, however, to think 



* In Ann. Scott. Nat. Hist. 1896, 38-53— a Eafinesquian paper which is 

 likely to give trouble to future nomenclaturists. 



t He gives among the synonymy " V.paniculata, leges " ; for an explanation 

 of this authority see Journ. Bot. 1898, 106. The name, however, is given by 

 Hornemann, Hort. Hafn. 594 (1815) as cited in the Index Kewensis,
