The genus Lochncra has been separated from the genus Vinca, under which it is 

 included in Bentb. & Hook. Gen. PI. t. 2, p. 70-3. In the genus Lochnera the 

 filaments are short and slender, the anthers glabrous at the tip, lanceolate, the 

 connective not produced, and the stigma glabrous. In the genus Vinca as now 

 adopted, the filaments are clarate, the anthers hairy at the tip, broadly oblong, the 

 connective produced, and the stigma hairy.
