Nevertheless, had they looked into the standard works of reference, 
without study of which no taxonomist should allow himself to pub- 
lish, they would have found that the plants which made up the original 
Alsine Wahlenb: and the species which are universally placed with 
them have already had more than a grocer’s dozen of generic names 
most if not quite all of which are clear from duplication! The sounder 
European botanists reduce Alsine Wahlenb. to the Linnean Minuartia 
(1753), but if Minuartia is held to be distinct there are still plenty 
of names from which to select. Leptophyllwm Ehrh. Beitr. iv. 147 
(1789),2 was based on Arenaria tenuifolia L. which is placed by Pax 
1 Wahlenb. FI. Lap. 127 (1812). 
2 The sea lespes Rules of — S pieorsipntt wisely state that ‘The mere indica- 
tion of species as belonging to _does not allow us to accept the genus. ..a5 
mentees and effectively cubliched”s: ce ae bag “American” Code rules that a 
genus is published by “‘a reference to a ape des by citation with 
a previously published binomial = and ot apd thors ‘of the American Code regarding the 
retention by the ss svdreleganl Con

In other werds, on page 20 there is no men of Filiz m 5 hind the only word of diagnosis 
“‘enparasol” describes the pelfate indusium e "Patch, not the reniform indusium of 
Filiz mas. ‘The American Code would have won more respect for its “precision” if it had 
stated the fact, sa is on p. 55, in the index or 
it is placed aurea” but alae Dros pteris.’
