Hom ha reunit en el present treball un seguit de comentaris taxonòmics, nomenclaturals i corològics de les espècies de Verbascum L. (includ. Celsia L.) presents a l'illa de Mallorca. Per a l'elaboració d'aquest estudi hom ha consultat els següents herbaris: BC, BCC, BCF, COI, MA, MAF, MPU, així com els del Col•legi d'Apotecaris de Palma (Herb. Apot.), Coilegi de la Salle de Pont d'Inca (Herb. Bianor) i de Palma (Herb. Bianor- P), i els herbaris particulars de J. Orell (Herb. Orell) i de F. Bonafe (Herb. Bonafe).This work presents taxonomical, nomenclatural, and chorological studies on the taxon Verbascum L. (includ. Celsia L.) of Majorca island. The species V. nigrum Vill. and V. Virgatum Stockes must be eliminated from the Balearic Flora. V. boerhavii L. var. bicolor (Bad.) Arcang. and V. blattaria L. are recorded for the first time in the Balearic Islands; likewise, V. boerhavii var. knochei is described. V. portae Willk. is regarded as coespecific with V. boerhavii L. var. boerhavii

The Genus viola in the Balearic Islands

S'ha dut a terme l'estudi del gènere Viola a les illes Balears. Es proposen dues noves combinacions nomenclaturals: Viola suavis Bieb. subsp. barceloi (Nyman) Orell & Romo, comb. nova i Viola odorata L. subsp. stolonifera (Rodríguez Femenías) Orell & Romo, comb. nova. Es descriuen tres noves notosubspècies de l'illa de Mallorca: Viola alba L. nothosubsp. neusii Orell & Romo, nothosubsp. nova (=Viola alba subsp. dehnhardtii x V. jaubertiana); Viola alba L. nothosubsp. bonaefidei Orell & Romo, nothosubsp. nova (=V. alba subsp. dehnhardtii x V. suavis subsp. barceloi); i Viola suavis Bieb. nothosubsp. cardonae nothopsubsp. nova (=Viola suavis subsp. barceloi x V. jaubertiana). S'exposen la corologia i l'ecologia dels tàxons de Viola presents a les Illes i es valoren algunes citacions antigues, probablement errònies.Following the study of Balearic taxa of the genus Viola, two new nomenclatural combinations are proposed: Viola suavis Bieb. subsp. barceloi (Nyman) Orell & Romo, comb. nova; and Viola odorata L. subsp. stolonifera (Rodríguez Femenías) Orell & Romo, comb. nova. Three new nothosubspecies from the island of Majorca are described: Viola alba L. nothosubsp. neusii Orell & Romo, nothosusp. nova (= Viola alba subsp. dehnhardtii x V. jaubertiana); Viola alba L. nothosubsp. bonaefidei Orell & Romo, nothosubsp. nova (= V. Alba subsp. dehnhardtii x V. suavis subsp. barceloi); and Viola suavis Bieb. nothosubsp. cardonae nothosubsp. nova (= Viola suavis subsp. barceloi x V. Jaubertiana). The chorology and ecology of the Balearic taxa of the genus Viola are presented and some of the oldest reports, which are probably erroneous, are discussed

Experiences of historical introductions in Majorca: the case of "Ranunculus weyleri" (Ranunculaceae)

Conservation translocations did not begin to be documented until the late decades of the twentieth century in Spain. However, there is evidence that some endemic species were translocated in 1958 in Majorca (Balearic Islands) because the blasting of the highest mountain peak on the island for the installation of an American radar station could have endangered the survival of these endemic species. This is the case for Ranunculus weyleri Marès ex Willk., a threatened plant that consists of a few subpopulations with disjoint distribution. The aim of this study was (i) to search the personal documents of the botanist Jeroni Orell Casasnovas (1924-1995) —delegate of the Societat d’Història Natural de les Balears for the protection of the Puig Major flora before the blasting in 1958— to obtain information about this introduction and (ii) to perform a demographic census of its current conservation status. After the introduction in 1958, monitoring of the translocated plants in the following years 1963 and 1964 confirmed that the establishment was successful; currently, this subpopulation consists of 63 adult plants. Overall, the conservation translocation of R. weyleri sixty years ago was successful. Finally, we underline the utility of field notebook data for historical botanists who gathered valuable information but did not publish it elsewhere and the importance of publishing the results of current translocation actions, whether they succeed or not.<br /

Taxonomy of the genus Chamaesyce S.F. Gray (Euphorbiaceae) in the Iberian PeninsuIa and the Balearic Islands

A taxonomic study is undertaken of the ten taxa (nine of them specific) belonging to the genus Chamaesyce S.F. Gray (Euphorbiaceae) which are present in the Iberian Peninsula and the Balearic Islands and a dichotomic key is provided. The taxonomic characteristics or each taxon are discussed and the correct name, synonyms, description, chorology and ecology are given. The presence of Chamaesyce humifusa (Willd.) Prokh. in the Iberian Peninsula is confirmed and Chamaesyce humistrata (Gray) Small is recorded for the first time from Europe.Es realitza un estudi taxonòmic dels 10 tàxons (nou específics) del gènere Chamaesyce S.F. Gray (Euphorbiaceae) presents a la Península Ibèrica i les Illes Balears. Per a cada tàxon es valoren els caràcters d'interès taxonòmic i s'indica el nom correcte. la sinonímia, descripció, corologia i ecologia. Es confirma la presència de Chamaesyce humifusa (Willd.) Prokh, a la Península Ibèrica i se cita Chamaesyce humistrata (Gray) Small coma novetat per a Europa

Taxonomical value of the studied features is discussed.Se estudian los caracteres fitodermológicos de las ocho especies europeas del género Chamaesyce S. F. Gray. valorando su interés taxonómico

Preparation, Solid-State Characterization, and Computational Study of a Crown Ether Attached to a Squaramide.

[eng] Crystals of a disecondary squaramide covalently linked to a crown ether presents a great variety of inter- and intramolecular nonbonded interactions including C-H/ð contacts, C-HâââO and N-HâââO hydrogen bonds, and ð-ð stacking between squaramide rings. Latter interaction, the stacking between squaramide rings, can be considered as an experimental evidence for the proposed aromaticity of squaramide when it is forming hydrogen bonds, either as acceptor or donor
