A morphometric study of the known populations of Genista pulchella has been undertaken, based on herbarium specimens and field research. This has made it possible to provide a new taxonomic outline as the disjunct populations
of G. pulchella (western part of the Balkan peninsula, central Italy and southern France) seem to be distinct. A new
taxon is described: G. pulchella ssp. aquilana ssp. nov. (central Italy), a new combination G. pulchella ssp. villarsiana comb. nov. is proposed for the population from southern France, while G. pulchella ssp. pulchella can be
considered endemic to the Balkan Peninsula. Genista pulchella Vis., G. villarsii Clementi and G. villarsiana Jord. are
lectotypified. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society, 2007, 153, 245–254.

INTRODUCTION
During field research, A. Manzi collected a specimen
belonging to the genus Genista L. sect. Erinacoides
Spach (Conti & Manzi, 2003). The new site is the first
one in central Italy for the whole section.
The known entities of this section are mainly to be
found in the central and western Mediterranean
regions (Greuter et al., 1989; Valsecchi, 1993; Talavera
et al., 1998; Talavera, 1999). In peninsular Italy only
G. desoleana is present, along the Tyrrhenian coasts of
Liguria and on the Isle of Elba (Valsecchi, 1993), as
well as in Corsica and Sardinia. In the eastern Mediterranean area G. parnassica Halacsy occurs, for
example in Greece on Mount Parnassus, Samotraki
and Samos, but further study of this area is warranted
(Gibbs, 1970; Strid, 1986). Genista pulchella, once
included by Gibbs (1966) in sect. Spartioides, is placed
by Uribe-Echebarría & Urrutia (1988) in sect.
Erinacoides.
Further study and comparison with herbarium
specimens led us to refer Manzi’s plant to G. pulchella
s.l. The known European populations therefore have
been compared morphologically.
Genista pulchella was described by de Visiani (1830)
based on a specimen collected by Biasoletto on the Isle

of Pag. In 1841 Clementi described G. villarsi from
specimens collected on Mt Zavelin between BosniaHerzegovina and Croatia. He identifies the populations discovered by Villars in southern France and
named G. humifusa L. as part of G. villarsii. This
taxon was later treated as a synonym of G. pulchella
(Gibbs, 1968; Greuter et al., 1989; Talavera, 1999) or
as its subspecies, G. pulchella ssp. villarsii (Clementi)
Kerguélen (Kerguélen, 1993). Jordan (1847) reexamined the Provençal population and concluded, as
had Clementi, that it did not represent G. humifusa.
He named it G. villarsiana and provided a full description. He probably ignored Clementi’s work and its
resemblance to G. pulchella as he only considered
G. pilosa as its closest species.
In Greuter et al. (1989) G. pulchella was recorded in
the former Yugoslavia, Albania and France. The populations found in northern Spain (Alava, Burgos,
Navarra) were recognized by Uribe-Echebarría &
Urrutia (1988) as a separate taxon, Genista eliassennenii Uribe-Ech. & Urrutia, but were later synonymized with G. pulchella (Talavera, 1999). Recently,
Rivas Martinez et al. (2002) have confirmed its distinctness, and placed it as a subspecies of G. pumila as
G. pumila ssp. eliassennenii (Uribe-Ech. & Urrutia)

between G. pulchella s.l. and Genista pumila. Rivas
Martinez’s conclusion will be accepted until it is possible to observe this population in situ.
MATERIAL AND METHODS
In order to understand the systematics of G. pulchella
s.l., 162 specimens were studied from the following
herbaria: APP, B, FI, G, MA, PAD, ZA (acronyms following Holmgren, Holmgren & Barnett, 1990, and
additions), 54 from Abruzzo, 54 from France and 54
from Croatia.
Each specimen (flowers and leaves) was soaked in
water for a few seconds before measurements were
taken (the number of measured specimens is not constant for each feature).
Excursions were made to the following localities at
least twice to collect flowering and fruiting specimens:
Mt Mosor (Croatia), Gorges du Verdon (France) and
Colle delle Macchie (Italy).
The following measurements were taken: 1, height
(cm); 2, length (cm) of young woody ridged stems; 3,
diameter (mm) of young woody ridged stems; 4, middle
leaf length (mm); 5, middle leaf width (mm); 6, middle
leaf length/middle leaf width; 7, length of standard
(mm); 8, width of standard (mm); 9, length of wings
(mm); 10, width of wings (mm); 11, length of keel
(mm); 12, width of keel (mm); 13, length of standard/
length of wing; 14, length of standard/length of keel;
15, length of wings/length of keel; 16, length of legume
(mm); 17, width of legume (mm); 18, length of legume/
width of legume; 19, length of the hairs on legume
(mm).
The dimensions of the branches were taken from
young ridged branches. The diameter was measured
in the median part. The features considered were
generally measured once on each specimen, so that
only one leaf, one flower, etc., was measured for each
individual.
The density of hairiness appears to be a useful distinguishing character, but was not used because of the
difficulty in quantifying it. Genista pulchella ssp.
aquilana is the hairiest variant and is grey in colour.
In the other taxa, hairiness was not as dense, par-
KEY
ticularly in G. pulchella ssp. villarsiana, which is normally green.
The dimensions and number of bracteoles seem to
vary within the same population. For this reason they
have not been taken into consideration although there
may be statistically significant differences.
Another feature that was observed in nature, but
not quantified, and which might depend on the type of
habit is the number and density of the flowers for each
individual. French individuals are often completely
covered in flowers, and for this reason are often used
as ornamental plants. The other populations are usually not as floriferous. The Abruzzo is least floriferous.
The most useful characters in the morphological
analysis were: (1) height, (2) young woody ridged stem
length and width, (3) middle leaf length and width, (4)
length of standard and (5) length of hairs on legume.
RESULTS
The analysis of morphological features (Table 1)
allowed the identification of three clearly distinct and
separate units: G. pulchella ssp. pulchella (western
Balkans), G. pulchella ssp. aquilana (central Italy)
and G. pulchella ssp. villarsiana (southern France).
The height of the individuals and the length of the
woody stem length directly connected to it produced a
different habit, which allows for easy distinction in the
field (Figs 1–3, 4A–C). In herbarium specimens, distinction is not always as easy, and it is necessary to
measure other features. The leaves are longer and
wider in G. pulchella ssp. pulchella, whereas the
Abruzzo populations are intermediate between this
one and the French population (Fig. 4D), but their
leaves are narrower (Fig. 4E), so that the ratio
between length and width is higher (Fig. 4F). Plants of
the French population have shorter leaves (Fig. 4D).
In general, individuals from the Abruzzo population
are larger. The standard is larger in plants from
Abruzzo (Fig. 4G). The French individuals are generally smaller. A feature which helps distinguish individuals from Abruzzo is the length of the hairs of the
legume, which are clearly longer in this population
(Fig. 4H).

Chromosome number: 2n = 18 + (0 − 2B), exceptionally, only once 2n = 24 + 2B, according to an unpublished number carried out by Cusma Velari e Feoli
Chiapella (Trieste). Chromosoms are 0.88–3.08 µm
long (Fig. 11).
Habitat: Rocky slopes and cliffs of limestone ‘calcare
massiccio’ (950–1200 m).
Distribution: Known only from the type locality.
Observations: The type locality lies within the
National Park of Gran Sasso-Monti della Laga, along
the south-western slopes of Colle delle Macchie, at an
altitude of about 1100 m. At present the plant is only
known from this area where there are numerous individuals. The population is small and confined to altitudes of 950–1200 m. It can be found on ‘calcare
massiccio’, the limestone rock of the lower Lias. Above
1200 m, more recent rocks take the place of this calcare massiccio (Vezzani & Ghisetti, 1998). The site
was reafforested with Pinus nigra Arnold var. italica
Hochst. between 1930 and 1940 (Console, 1984). Reafforestation and the presence of an old quarry have
probably reduced the population, and it should be
included in the Red Data Book of Italian plants (Conti,
Manzi & Pedrotti, 1992, 1997) both on regional and on
national levels. Following IUCN criteria (IUCN, 2001)
it deserves the status of VU D2. The National Park
will secure its survival in the future; there is a programme in place to reduce the number of pines in the
area as they are damaging the natural vegetation.

DISCUSSION
Extant populations of the three subspecies might be
remnants of a previously larger distributional range
that experienced contraction during the Quaternary,
leading to the present fragmentation. They have a Tertiary origin and have become schizoendemics as a
result of geographical isolation.

Figure 5. Holotype of G. pulchella ssp. aquilana ssp. nov.
The thorny cushion formation (Hedgehog heath)
dominated by Genista and Astragalus species characterizes the summits of some Mediterranean mountains (Pignatti et al., 1980). In this specific case they
live at lower altitudes, mainly on rocky slopes.
Several authors, although not all agree, have stated
that the genus Genista originated within the Iberian
microplate (e.g. Quezel, 1995). This is probably true
particularly for sect. Erinacoides.
In the Messinian period (c. 5 Mya), when the Mediterranean basin at least partially dried out, flora of
subdesert regions might have had an opportunity to
occupy this area (from the south), up to the Iberian
Peninsula, and/or may have reached Sardinia–Corsica,
Sicily and finally the Italian peninsula (Pignatti,
1982). In fact, the centre of diversity of this section is
represented by the Iberian Peninsula where one can
find up to nine of the 21 known taxa, others occur
singly in Algeria, France, Corsica, Sardinia, Italian
Tyrrhenian regions and Sicily, and two have reached
the Balkan peninsula and the Aegean area. Within this
section, Genista pulchella has the widest distribution.
