?1. De Novis Flora Lusitana Commentariis
In memoriam A.R. Pinto da Silva (1912 ' 1992)
Aliquot notulae plantarum Iberiae Macaronesiaeque
Several short notes on the plants of Iberia and Macaronesia issuing from
taxonomical work on these territories are presented: two taxa, two nothotaxa
and a new name are proposed as new to Science1.
1.Salix x nobreinothosubsp.carloscostaeE. Portela-Pereira, Capelo &
C.Neto, nothosubsp. nov.
Inter parentibus vero intermedia, ad typum S. x nobreiiSamp. ex Cout. (i.e. S.
atrocinerea x S. salvifolia subsp. salvifolia) similis sed foliis lineari-
lanceolatis, etiamque indumento, aliquando ferrugineo, sparsiore differt. [=S.
atrocinerea Brot. x S. salvifolia subsp. australis Franco]. Habitat cum
parentibus ad Iberiam meridionalem. Hoc nomen ad botanicum clarissimum
olissiponensem José Carlos Costa dicatum est. Holotypus: LISE 80744, Mértola,
Pomarão 'ad margines rivi Guadiana', Bento V. Rainha 6069, 28.05.1963

=Salix x nobreinothosubsp. transtaganaE. Portela-Pereira, Capelo, C. Neto &
J.C. Costain Silva Lusitana21 (1) : 126, nomem nudum.
Comment: The names S. x secaliana Pau & Vicioso and S. x nobrei Samp. ex
Cout. apply to nothotaxa of S. atrocinerea Brot. and S. salvifolia L. subsp.
salvifolia. As we recognize S. salvifolia subsp. australis Franco, their hybrid
is, thus far, unnamed. Comparable to S. x nobreinothosubsp.nobrei,but leaves
linear-lanceolate with less dense indumentum, sometimes with some reddish
hairs. Endemic to SW Iberian Península, sympatric with parent taxa.
2.Rubia occidensCapelo, M. Seq. & H. Schaef.,sp. nov.
Ad Rubia agostinhoii Dans. & P. Silva affinis etsi nonnumquam verticilli
septem foliatus sint autem ab hac differenti maxime ramorum principalium foliis
atroviridibus coriaceis linearii-lanceolatis longiter attenuatis, longioribus:
ab 25 mm ad 55 mm longas interdum usque 80 mm longitudine, ab 1.5 mm ad 3.0 mm
latas; sed tamen nec umquam cuiusmodi R. agostinhoii eisdem foliis brevioribus
(ad usque 25 mm) suavis herbaceis laete viridia anguste-eliptici vel anguste
spathulatis, breviter atenuatis vel fere truncatis mucronatisque. Hanc R.
occidens habitat in Madera, Insulis Canariensis necnon ad meridiem Hispaniam,
autem R. agostinhoii tantum in Insulis Azoricis habitat. Holotypus: LISE 95134,
Madre del Agua, Tenerife, W. Wildpret & A. Garcia Gallo, 10.07.1980
= Rubia agostinhoi sensu auct mad.& canar. nonDans & P.Silvain Agron.
Lusit.36: 62 (1974)
=Rubia peregrina subsp. agostinhoi sensu auct. mad. & canar. non (Dans.
& P.Silva)Valdés Vermejo&Ginez Lopezin Anales Inst. Bot. Cavanilles 34:
168 (1977)
Comment: The name Rubia agostinhoi Dans. & P. Silva has been applied
throughout to all macaronesian and south-iberian Rubiae with eight-leaved
whorls. In fact, either from, as defined in original diagnosis, the type
specimen (LISE 70247), herbarium and field observations, it strikes that plants
with leathery dark-green linear-lanceolate, gradually tapering to apex, very
long leaves (25-80 mm) in main stems, occur in mountains of south coast
continental Spain, Madeira and the Canaries; and that Azorean plants have much
smaller, up to 25 mm long, light-green smooth narrow-elliptic or spatulate
suddenly attenuate or even truncate, mucronate leaves. Therefore, the name R.
agostinhoi Dans. & P. Silva should be used to refer plants of the Azores
alone, being an endemism of the territory. Other iberian, madeiran and canarian
populations, we propose, to be a distinct species: R. occidens. Molecular
studies are underway confirming separation (Schafer et al., ined.). Derivation
is from the latin word for 'West' or 'sunset'.
3.Viola sequeiraeCapelo, R. Jardim, J. C. Costa, Lousã & Rivas Mart.,
sp. nov.
A Viola riviniana differt petalis lateralis divaricatis paene horizontalis vel
parvo angulo descendentibus, anguste ovatis-rhomboidalis ratione longitudine /
latitudine maior quam 1.6, atenuatis; petalas superiores etiam similia haec
sunt; V. sequeirae, dissimiliter V. riviniana, nunquam petalas deorsus
ostendentes, latis elipticis ratione longitudine / latitudine ad usque 1.4
(1.6), obtusis habet. Praeterhac V. sequeirae ad Viola anagae Gilli - Feddes
Repert. 89(9-10): 595. 1979 plus minusve comparatur, sed his petalae V.
riviniana similis sunt. Habitat tantum in Insula Madera. Hoc nomem ad botanicum
clarissimum Miguel Menezes de Sequeira gratio animo dicamus. Holotypus: LISI
220/209, M. Lousã & J.C. Costa, Ilha da Madeira, Funchal, Chão da Lagoa,
28.05.2000: the specimen on the right side of the sheet.
= Viola riviniana auct. mad. nonRchb.
Comment: In the Violacf.riviniana populations of Madeira it strikes that the
lateral petals are nearly horizontal and spreading when compared to clearly
downward position in the typical continental ones. Moreover, the narrow
rhomboid-elliptical, tapering to the apex, lateral and upper petals allows
distinction from the candidate V. anagae of Tenerife (Canaries). The later has
largely elliptical blunt lateral petals instead, similar to those of V.
riviniana. Thus, V. sequeirae is an autonomous species endemic to Madeira.
4.Ulex x dalilaeCapelo, J.C. Costa & Lousã,nothosp. nov.
Plantae ipsae a parentibus (=Ulex densus Welw. ex Webb x Ulex jussiaeiWebb)
intermediis ab Ulice denso ramis divaricatiis erectis etiamque bracteas
spinarum primae ordinis inter U. jussiaei U. densoque intermediis anguste-
triangulariis, rigescentibus, spinescentibus differt. Hoc nomen ad botanicam
clarissimam Dalila Espírito-Santo dicatum est. Holotypus: LISI 49754, J.C.
Costa, J. Capelo & M. Lousã, Sintra, Linhó, 'num mato baixo de solo
calcário', 24.02.1993.
Comment: Hybrid individuals with intermediate characters between Ulex densus
(in hard dolomitic limestone) and Ulex jussiaei(several silicate or calcareous
substrata) are found in locations where both species are sympatric. In U. x
dalilae the cushion habit is less evident when compared to U. densus with erect
spreading branches. Axillary bracts (phyllodia) of first-order spines are
narrow-triangular but stiffer and spinier than those of Ulex densus and
somewhat closer to those of U. jussiaei.
5.Daphne gnidium subsp. maritima(Rozeira) Capelo, J.C. Costa, Esp. Santo
& Lousã, stat. nov.
Basionymon: Daphne gnidium L. var. maritima Rozeira, Agron.Lusit. 24: 169,
1964.
Comment: it differs from the type by being a denser cushion-like shrub with
much shorter internodes and also by having obovate-lanceolate or spathulate
leaves abruptly attenuate, obtuse, mucronulate, with somewhat hyaline margin.

As the new 'Melbourne Code': Reg. Veg. 154(2012) allows either descriptions in
the Latin or English languages, in case of doubt, the authors meant the
reference description to be that in the Latin language.
