THE NOMENCLATURE OF NYMPH^A, ETC. 11 





thirty- three years later (in 1840), but the Wallichian genus Anneslea 

 (1824) must take another name, unless it is urged that the difference 

 in termination is enough to justify the retention of the two names. 



The authors of the * Genera ' were no doubt in this, as in so 

 many other cases, actuated by a fear of the inconvenience which 

 would arise from the restitution of the correct name. They were 

 perfectly conscious that the name existed, for Calliandra stands 

 thus in Gen. PL i. 596: — " Calliandra Benth. in Hook. Journ. 

 Bot. ii. 138 (Anneslea Salisb. Parad. Lond. t. 64, non Wall.)" 

 And if we turn to Bentham's foundation of his genus, we read 

 "I propose the name of Calliandra for the genus indicated by 

 DeCandolle under Inga anomala as the Anneslea of Salisbury, a 

 name applied by Dr. Wallich to a very different East Indian 

 genus." DeCandolle (Prodr. ii. 442), speaking of Inga anomala? 

 Kunth. = Anneslia grandiflora Salisb., says, — "An genus cum 

 2 sequentibus et forsan praecedente proprium (Anneslea [sic] Salisb.) 

 admittandum ? " 



The case, then, is quite clear, and stands thus : 



ANNESLIA Salisb. Parad. t. 64 = CALLIANDKA Benth., Hook. 



(1807). Journ. Bot. ii. 138 (1840). 



A. grandiflora Salisb. I. c. = C* grandiflora Benth. I . c. 



The other species of Calliandra (79 according to Gen. PI.) 

 must follow suit; but this must be the work of a future mono- 

 grapher. 



It follows from what has been said that Wallich's genus 

 Anneslea must be reduced to the rank of a synonym. Its author 

 distinctly states (Plant. Asiat. Bar. i. 65) that he created it on the 

 understanding that the plant so named by Roxburgh and Salisbury 

 had been relegated to Euryale and Acacia respectively ; now that 

 Salisbury's genus is allowed to stand, Wallich' s Anneslea must dis- 

 appear. The two species which it comprises are without a generic 

 name ; for Anneslea Wall, is in the rare position of never having 

 received another generic appellation. 



An innominate genus is so manifestly inconvenient that I 

 venture to propose for it the name of Daydonia, in compliment to 

 Mr. B. Day don Jackson, whose services to Botany in his position 

 as Secretary to the Linnean Society deserve recognition. His 

 work upon the great 'Index of Plant-names,' which will neces- 

 sitate many such changes of name, as well as the zeal he has 

 shown in promoting the only sound principle which can govern 

 botanical nomenclature, seem to render this commemoration spe- 

 cially appropriate. The specific names need not be changed. 



DAYDONIA = Anneslea Wall. 



D. fragrans = J.frograns Wall. 



D. crassipes = A. crassipes Hook, ex Chois.
