OF THE GENUS SYMPHYTUM. 541 
S. bulbosum the areas are partly distinct and partly overlapping ; that of 
S mediterraneum is within the area of S. tuberosum, and just outside that of 
S. bulbosum ; S. Gussonei and S. Zeyheri are within the area of S. bulbosum, 
and outside that of S. tuberosum. 
Alter much consideration and careful comparison of numerous specimens, 
I have decided to treat these plants as species, in accordance with the views 
of those authors who, having studied them in their natural habitats, or 
in other ways, have had the opportunity of forming a definite opinion, have 
arrived at the conclusion that they are distinct entities, and not chance 
variations of a single species.

In Koch’s type specimen, which cannot now be found, the root was 
wanting ; but Italian and French authors have attributed to it a root 
similar to that of 5. bulbosum, viz. slender and creeping, with tubercles 
at intervals, because S. mediterraneum, Gussone (S. Gussonei, Schultz), has 
such a root. 
The comparison of plants named S. mediterraneum, Koch, from Aubagne 
with authentic Sicilian specimens of S. Gussonei, Schultz, which I had tried 
in vain to reconcile with each other and with descriptions, shows that there 
are two distinct forms, allied to S. tuberosum, Linn., but varying from it in
