Several matters in this protologue call for comment. 
In genera with several species, Linnaeus provided con- 
cise diagnostic phrase-names enabling the species thereby 
to be distinguished, e.g. Hippophaé foliis lanceolatis and 
Hippophaé foltis ovatis tor H. Rhamnoides and H. cana- 
densis. Such phrase-names were comparative; they con- 
trasted specific features. In a genus with only one spe- 
cies, such as Cannabis, no such diagnostic phrase was 
required and would indeed have been illogical, since ob- 
viously the one and only species could not be contrasted 
with itself. 
Typification of the generic name of such a monotypic 
genus Is essentially the same as typification of the specific 
name; the nomenclatural type of the one must be the 
nomenclatural type of the other. Hence, the generic 
name Cannabis L. and the specific name Cannabis sativa 
L.. must be permanently associated with the same ele- 
ment. The Species Plantarum citations of literature be- 
gin with Linnaeus’s own Hortus Cliffortianus (1788), 
where fuller synonymy will be found; the other citations 
likewise refer to plants cultivated in Europe. He used 
the terms mas and femina and the signs é and ¢ for male 
and female plants in a purely biological sense and sorted 
his synonyms accordingly. Knowing hemp only as a 
cultivated plant in Europe, he evidently assumed that it 
must have been introduced from elsewhere, presumably
