practice of Linnaeus has been introduced into the Botanical Gar- 
den and Museum. This will still be maintained, and we therefore 
write all specific names with a small initial letter, except those 
derived from personal names and those which are substantives 
( generic names still or formerly in use); for example, Ficus i- 
dica, Circaea lutetiana, Brassica Napus, Solanum Dulcamara, 
Lythrum Hyssopifolia, Isachne Buttneri, Sabicea Henningstana.* 
g. When generic or specific names are formed from proper 
names we add the letter a for the genus to such names ending in 
a vowel or in 7, and 7 for the species, thus Glazioua (from Glaziou), 
Bureaua (from Bureau ), Schitzea (from Schiitze), Kernera (from 
Kerner ), also Glaziout, Bureau, Schiitzei, Kerneri; if the name 
ends in a we change this vowel for euphony to ae, thus from Colla, 
Collaea; in all other cases we add za or z to the name, thus 
Schittzia (from Schiitz), Schiitsi, etc. This applies as well to 
names terminating in ws, thus Magnusia, Magnus (not Magni), 
FTieronymusia, Hteronymusi ( not Hieronymi) ; the adjective forms 
of proper names are formed in a corresponding manner, thus 
Schiiizeana, Schittziana, Magnusiana. To make a difference in 
the application of the genitive and adjective forms is not practi- 
cable at the present time.t 
10. In forming compound Latin or Greek substantives or ad- 
jectives the connecting vowel between the roots is to be written 
7 in Latin, o in Greek; we thus write menthifolia, not menthae- 
Sfolia 
11. We recommend the avoidance of such combinations of 
names as produce tautology, as Linxaria Linaria or Elvasia elvastoi- 
des ; it is permitted to deviate from priority in the cases of such 
names which have arisen from gross geographical errors by the 
author, as, for example, Asclepias synaca L. (which originated in

* Specific or varietal names derived from persons or places, or used as the geni- 
tive of generic names or substantives, are to be printed with a capital initial letter.

The American rule calls for wider capitalization than the German, The matter 
is of little consequence as regards nomenclature; the increasing tendency to decapi- 
talize all specific names seems to us, however, unfortunate. a 
+ We infer from this that specific names such as Schiitsei and Schiitscana would 
not be maintained in the same genus, and this is highly desirable, 
} This will, we think, be generally approved,
