[This name was originally published as Zigadenus in 
Michaux's Fl. i. 213 (1803), and was taken up in this 
form by many authors including Dr. Gray, Ann. Lyc. 
М. Y. iv. 111 (1837). In 1837 Endlicher (Gen. 135) 
altered the spelling to Zygadenus, a form which has been 
pretty generally accepted. ‘The change is certainly in 
the direction of philological accuracy and from the 
literary point of view may seem justifiable, but it belongs 
to a class of alterations which, if permitted in one case, 
lead by exceedingly slight gradations to changes of 
greater and greater magnitude, which, dependent solely 
upon varying taste and judgment, would seriously 
menace the stability of nomenclature. ‘These changes 
are rendered the more undesirable from the impossibility 
of citing (truthfully) the original author as the authority 
for the altered form of the name. One would thus in the 
present instance be obliged to write Zygadenus Endl. for 
technically there was no Zygadenus Michx.]
