1) Numerus sat magnus specierum novarum a cl Litwinow in Flora 
Rossica exsiccata publicabitur. 
2) Addimus species nonnullas novas iam a cl Ruprecht in Caucaso 
orientali lectas et in herbario Academiae Petropolitanae conservatas, pariter ac 
species nonnullas iam descriptas, sed in Caucaso adhuc non lectas, a cl. Lit- 
winow primum inventas.
