which are furnished towards the top with but short small hair. Zaula 
semiamplexicaulis, Rent., from Geneva, Bois dé Batie (Lagger !) ap- 
pears to be a hybrid between I. salicina and I. Vaillantii, whilst 
I. semiamplexicaulis, Visiani, is identical with I. squarrosa, Linn. 
I. media, M. B., judging from specimens from Creuznach, Bingen, 
and Mainz, seems to be a hybrid between J. salicina and I. Germanica. 
I. hybrida, Baumg., seems to be a hybrid between J. salicina and 
I. ensifolia, judging fiom specimens from Hungary (Kruzisch !), 
Vienna (Skofitz !), Serbia (Pancic ! mixed with Z. ensifolia).

“I. ensifolia, Linn., is the nearest ally of 7. salicina, and is confined 
to southern Europe, extending from the Tyrol, Piedmont, Tstria, Carin- 
thia, Austria proper, Hungary, Banat, Serbia, Prussia, to Asia Minor, 
where C. Koch collected it in Grusia. 
“I. ensifolia, Fries! Herb. Norm. xiv. 1; Gottland (Bunge); 
in petra calearea (Trüsk-Hedarne), inter Juniperos leg. O. Westóó,— 
would seem to be on account of its narrow involucral leaves, small 
flower-heads, the entire glabrousness of the whole plant, and the widely- 
different geographical Tange, a new species, or perhaps only a more 
narrow-leaved form of J. salicina. Fries (Sum. Veg. p. 37) seems to 
entertain the same opinion. Many Compositz occur with broad and 
narrow leaves; for instance, Hieracium umbellatum, Linn. =H. 
Jilifolium, Fries, Symb. Hier, p. 178.”
