if the name has two or more syllables, the first syllable ant 
the first letter of the following one are taken ; or, the two first 
ir they are both consonants (Juss. for De Jussieu ; Rich. fo 
Richard), 
When it is found: necessary to give more of a name, for the 
sake of avoiding confusion between names beginning with the 
same syllables, the same system is to be followed. For instance, 
two syllables are given, together with the one or two consonants _ 
of the third ; or else one of the last characteristic consonants 
of the name is added (Bertol. for Bertoloni, so that it may be 
distinguished from Bertero ; or Miche. for Michaux, to prevent _ 
confusion with Micheli), Christian names or accessory desig- 
nations, serving to distinguish two botanists of the same name, 
are abridged i 
in the same way (Adr. Juss. for Adrien de Jussiel, — 
Gertn. fil. or Gertn. f. for Geertner son). 
When it is settled custom to abridge a name in another 
manner, it is best to conform to it (LZ. for Linnzus, St.-Hil. 
for Saint-Hilaire).
