Remarks:—
Two specimens
in PAV were collected on the same date by Pietro Rossi in Prato San Pietro. In the protologue Zahn indicated the wrong locality Ponte San Pietro in Val Sassina. The correct name is Prato San Pietro as stated on the label of Pietro Rossi. One of the
two specimens
(PAV-LOM014969) has damaged capitula that are enclosed in a paper bag. The second one (PAV-LOM014260) is a well-preserved specimen that bears two different labels handwritten by Zahn. On the first label there is only the new combination [“
Hieracium murorum
L. (grex
H. tenuiflorum
Zahn H.
d.
Schweiz
p 221) n. ssp.
pseudo-merianum
Rossi et
Zahn 1923
”]. On the second label there is a long diagnosis handwritten by Zahn, describing the new subspecies in detail (
Fig. 3
). This specimen agrees perfectly with the protologue, and therefore the specimen is designated here as a
lectotype
. The second specimen (PAV-LOM014969) can be considered an
isolectotype
.
