INTERNATIONAL RULES OF BOTANICAL NOMENCLATURE. 85 
Recommendation xix. “To avoid publishing or mentioning in 
their publications unpublished names which they do not accept, 
especially if the persons responsible for these names have not 
formally authorised their publication.” See Rec. xive. 
Recommendation xxi. “To give the etymology of new generic 
names and also of specific names when the meaning of the latter 
is not obvious.” 
Recommendation xxiv. ‘Separate copies should always bear the 
pagination of the periodical of which they form a part; if desired 
they may also bear a special pagination.” 
Article 43, Recommendation xxv (in part). “ Authors’ names 
put after names of plants are abbreviated unless they are very 
short. . . When it is a well established custom to abridge a 
name in another manner, it is best to conform to it (L. for 
Linnaeus, DC. for De Candolle, St. Hil. for Saint Hilaire), In 
publications destined for the general public and in titles it is 
preferable not to abridge.” : 
In Germany and France it is the custom to write Linné 
(Linnaeus) with a simple L. or L. f. for his son, not Linn. 
as in the Hnglish habit. 
This is not an important matter, but I recommend that 
the continental practice be, followed. Linné is so pre- 
eminent in Botany that this privilege of a simple letter 
can be granted him as a solitary exception; nobody would 
mistake L. for Lindley or for any other botanist. 
Article 50. ‘‘No one is authorised to reject, change or modify a 
name (or combination of names) because it is badly chosen, or 
disagreeable, or another is preferable or better known, or because 
of the existence of an earlier homonym which is universally 
regarded as non-valid, or for any other motive either contestable 
or of little import. (See also Art. 57).” 
I have already dealt with this point.*
