CUCURBITACEAE. 



Melothria micrantha, F. v. M. Near Kopperamanna. 

 (Dist. C; Prof. Osborn.) ''Common in floodbed of Cooper^ 

 Creek." The names which this plant has received are: — 



Cucurhita micrantha, F. v. M., in Trans. Phil. Soc. Vict. 

 i., 17 (1855). 



Cucumis ( 1) Muelleri, Naud., in Ann. sci. nat. 4"''e ser. 

 xi., 84 (1859). 



Zehneria micrantha, F. v. M., Fragm. i., 182 (1859). 



Muhia micrantha, F. v. M., Fragm. ii., 180 (1861). 



Melothria Muelleri, Benth., Fl. Aust. iii., 320 (1866). 



Melothria micrantha, F. v. M., ex Cogn. in DC. Monogr. 

 Phan. iii., 603 (1881). 



The reason given by Naudin for changing the specific 

 name was that micrantha became inapplicable in the genus 

 Cucumis, but art. 50 of the Vienna rules expressly states that 

 a name is not to be changed "because it is badly chosen," 

 or because "another is preferable." There appears therefore 

 to be no doubt that Cogniaux was right in re-establishing 

 Mueller's specific name, Zehneria micrantha, Hook. f. in 

 Oliver, Fl. trop. Afric. ii., 560 (1871), is inadmissible owing
