Lectotype (here designated):—[Sicily] Mespilus Insengae Tin., Isnello Bosco di Montaspro. Affine al M. monogyna . Porta i fiori più piccoli ed i frutti ovali-allungati anche più piccoli. Le foglie trifide o pennatifide e qualche volta le lacinie sono distinte e distanti come nelle foglie pennate, le lacinie sono anguste ed acuminate. Trasmetto a Minà per raccoglierne quantità di saggi. [Close to M. monogyna . It bears smaller flowers and also smaller oval-elongated fruits. The trifid or pennatifid leaves and sometimes the laciniae are distinct and distant as in pinnate leaves, the laciniae are narrow and acuminate. I ask to Minà to collect quantities of samples.], s. d., s. c. [manu V. Tineo]; 3a. Mespilus Insegnae Tin., Aprili Majo Þ , in nemoribus montosis, s. c. [manu Gussone] ( NAP0001790 photo!) .

Note:— The epithet commemorates Giuseppe Inzenga, but the name was originally published as “insegnae”. In Giovanni Gussone hebarium at NAP there is a specimen with one twig with leaves and fruits sent by V. Tineo to G. Gussone bearing two labels: one written by Tineo with the locality and the description of the species; the other one prepared by Gussone and including the reference to his Flora Sicula Synopsis (Gussone 1845). In the herbarium of Francesco Minà-Palumbo in Castelbuono (MINA) there is a specimen ( MINA3769 ) including two twigs with leaves and fruits and two labels: one by F. Minà-Palumbo’s with the indication “ Mespilus Insengae Tin , b. pubescens, Pomieri , 17 June 1847 ”; the other label was by V. Tineo and includes the indication “ Mespilus Insengae Tin., Montaspro 1830 ”. No original material was found in PAL.

Here we designate the specimen housed in NAP as lectotype of the name Mespilus insegnae because it is more complete and better conserved. The specimen here designated fits the original description and corresponds to the current use of the name that is considered an accepted, independent, species (Bartolucci et al. 2018) or a hybrid (Pignatti 2017).
