Orobanche rapum-genistae
Thuill.
La Flore des environs de Paris

Thuillier 1799
).
LECTOTYPE
. —
France
. “Environs de
Paris
”, s.d.,
J. L. Thuillier
s.n.
(lecto-, designated here,
G

]photo!) (

.
NOTE
Beck-Mannagetta (1930) reports: “vidi spec. orig. in Herb. Petrop.” The study of the herbarium samples preserved in LE resulted in only
one specimen
from
Paris
[LE01148356] photo! coming from the herbarium of
Ledebour
which has no direct connection with
Thuillier
and therefore cannot be considered original material. A specimen was found in P[P04384660]photo! with a label bearing the name of the species and the indication “Herb. Thuillier” but without place of collection and date.
Another
specimen has been found in G[G00396694]photo! that the imprinted label authenticates as coming from the
Thuillier
herbarium.
It
was so labeled when included in the
Delessert
collection).
This
label demonstrates that it is one of the originals used for the
Flora of Thuillier. On
fact
Thuillier’s
collections were purchased in 1827 by the banker
Benjamin Delessert
and transferred to
Geneva
(
Lasègue 1845
).
In
addition, the specimen in G is more abundant, better preserved and more complete.
Therefore
, we chose the specimen G[G00396694] as the
lectotype
of
O. rapumgenistae
Thuill. It
includes two complete individuals and the basal portion of another one.
The
lectotype
designated here matches the protologue and corresponds to the current application of the name.
GENERAL DISTRIBUTION. — This species occurs from North West Europe to West and Central Mediterranean area including North Africa (

et al.
(2010) and in
APD (2022)
