Speciem hanc primo reperi 1890 circa Novorossijsk et ob speci- 

 mina pauca et habitu differentia provisorie retuli ad P. corymbo- 

 sum W. (var. oligocephalum m.), nolens speciem novam fingere. 

 Annis sequentibus ulterius observans hanc plantain, magnam copiam 

 hujus collegi non solum e loco natali, sed etiam et ex aliis statio- 

 nibus. Turn apparuit speciem hanc sat variabilem esse quoad nunie- 

 mm capitulorum (1 — 6), pubescentiam et caetera. Specimina in 

 apertis crescentia folia subtus magis canescentiahabent,inumbrosis— 

 magis yiridia et caet. Tamen speciminibus originariis Ledebourii 

 aon visis sub dubio diu haerebam, an re vera P. poteriifolium 

 Ledb. esset. Nunc in herbario Horti Petropolitani observo ipsius 

 Ledebourii specimina tria (a Nordmann' o lecta!) e Guria (nunc 

 §u°. Kutais). Ledebour in Flora Rossica (II, 550) incipit descrip- 

 tionem sic: „caule simplicissimo monocephalo" ; quod omnino ini- 

 HUum est, nam e speciminibus tribus duo caulem tricephalum habent,
