Taxonomic investigations on Psoralea palaestina (Fabaceae), a critical species of Mediterranean flora
2016
Psoralea palaestina is a critical and unappreciated species described from Palestinian territories, and currently treated as synonym of P. bituminosa, nowadays known as Bituminaria bituminosa. Nomenclatural investigations allowed to ascertain that it was validly described for the first time by Bassi (1768) and not by Gouan (1773), as previously thought. Extensive taxonomic investigations revealed that this very peculiar legume is morphologically well differentiated from the other allied known species. Therefore, it has to be properly treated at specific level and transferred to the genus Bituminaria, thus proposing a new combination: Bituminaria palaestina. Based on literature, herbarium an…
Integrative taxonomy sheds light on an old problem: theUlota crispacomplex (Orthotrichaceae, Musci)
2016
The combined use of morphological and molecular analyses has been proven to be useful in resolving taxonomic complexes with hidden diversity. In bryology, however, integrative taxonomy has rarely been employed to revisit relevant old, unresolved problems. One of these classical controversies is whether the Ulota crispa complex comprises one or three species. To elucidate this, an exhaustive morphological revision, based on numerous herbarium and fresh specimens from most of the Holarctic areas in which U. crispa has been reported, and molecular analyses, using one nuclear (ITS2) and three plastid (trnG, trnL-trnF, atpB-rbcL) loci on a selection of representative specimens, have been perform…
The naming and typification of the breadfruit, Artocarpus altilis, and breadnut, A. camansi (Moraceae)
2018
The historical background and typification of the widely distributed and highly appreciated breadfruit tree, Artocarpus altilis (≡ Sitodium altile; Moraceae), and breadnut, A.camansi, is discussed. Sitodium altile is lectotypified selecting a watercolour painting by Sydney Parkinson made in Tahiti in 1769, during James Cook's first voyage around the world (1768–1771) in HMS Endeavour, and preserved at the Natural History Museum of London. A specimen from E. D. Merrill's “illustrative specimens” of Blanco's Philippine plants in the United States National Herbarium is designated as the neotype for A.camansi.
Ulota drummondii(Orthotrichaceae, Bryopsida) in the Iberian Peninsula
2018
Ulota drummondii (Hook. & Grev.) Brid. is a Suboceanic Boreal-montane epiphytic moss whose disjunct distribution includes both coasts of North America, East Asia, as well as northern and central Europe, being an extraordinarily rare moss in its southernmost known localities in Europe. It was reported some years ago from northern Spain, but the revision of the specimens on which the record was based demonstrate to be misidentified. Therefore, this species was not included in the treatment of the genus Ulota in the Flora Briofitica Iberica. Recently, the species was collected 140 km away of the previous erroneous record, and this led to a search for other specimens from the main Iberian herba…

A conspectus of Tephroseris (Asteraceae: Senecioneae) in Europe outside Russia and notes on the decline of the genus
2021
Tephroseris is generally considered a difficult genus. Based on the examination of extensive herbarium material and considering the existing literature, we recognize seven species in Europe outside Russia. These are T. palustris, T. integrifolia with subsp. integrifolia, subsp. aurantiaca, subsp. capitata, subsp. maritima, subsp. serpentini and subsp. “tundricola”, T. balbisiana, T. crispa, T. helenitis, T. longifolia and T. papposa. Phylogenetic analysis of ITS and ETS sequences showed that these species fall into three lineages. These are: (1) T. palustris, clearly related to Arctic species of the genus; (2) T. integrifolia; and (3) the remaining species. Molecular dating of the T. integr…

Raksts par 2019. gada auga mazā zvaguļa Rhinanthus minor herbāriju, ko 1925. gada 20. jūnijā ievācis latviešu botāniķis un iedzimtības pētnieks Aleksandrs Zāmelis, un kas glabājas Latvijas Universitātes Muzeja Botānikas un mikoloģijas kolekciju Latvijas Herbārijā (Herbarium Latvicum).
Ruiša pūķgalve Latvijas Universitātes Muzeja herbārijā
2020
Par Gada augu 2020 tika izvēlēts Latvijas aizsargājamais augs ruiša pūķgalve, ko Latvijā pirmo reizi atradis dabaspētnieks Eduards Lēmanis (1841 – 1902) 1883. gadā Antonopolē. Tas kopā ar citiem ruiša pūķgalves herbārija paraugiem glabājas Latvijas Universitātes Muzeja Botānikas un mikoloģijas kolekcijās. Tie ir gan Latvijā, gan Igaunijā ievākti eksemplāri laika posmā no 1848. līdz 1977. gadam.
<strong>Nomenclatural types of <em>Hieracium</em> (Asteraceae) species described from the Balearic Islands (Spain) and several rela…
2021
A nomenclatural revision of the genus Hieracium in the Balearic Islands (Spain) is presented and the typification of five names: H. aragonense Scheele, H. balearicum Arvet‑Touvet, H. elisaeanum Arvet-Touvet ex Willkomm, H. majoricanum Arvet-Touvet and H. microscapum Arvet-Touvet, is discussed. The names are lectotypified using specimens preserved at COI, GRM, and P herbaria. Several comments for the names H. cataractarum Arvet-Touvet & Huter and H. praecox subsp. brachypus Freyn in Porta & Rigo are also provided.
Remarks on the type material of Linaria cavanillesii Chav. (Antirrhineae, Veronicaceae)
2013
ABSTRACT Some aspects concerning the type material of Linaria cavanillesii Chav. (Antirrhineae, Veronicaceae), which are conserved in different herbaria, are discussed. This name had previously been lectotypified on Tournefort's collections that are kept at the herbarium P, though they had been regarded erroneously as syntypes. Evidence is shown on the existence of a duplicate of the lectotype (isolectotype), which is conserved among the Salvador herbarium at BC (Institut Botanic de Barcelona), as well as of syntypes deposited in MA on which the illustration by Cavanilles cited in the protologue was drawn. Historical data are reported on collection sites and dates for all cited syntypes of …
