“…The unexpected phylogenetic relationship between T. gallica and the other three mentioned species is not resolved according to our present DNA data, although their identification is clearly supported by independent morphological and geographical data. The lack of phylogenetic resolution supports the use of other types of molecular markers or techniques which might clarify their genetic relationships and their taxonomic identification, as has been reported recently for other taxonomically difficult genera (e.g., Duminil et al, 2012;Prebble et al, 2012;Andr es-S anchez et al, 2015).…”

Tamarix is one of the taxonomically most complex genera among the angiosperms, and there is little consensus regarding its infrageneric classification. Here we present the most complete phylogenetic reconstruction of the genus to date. This includes a DNA phylogenetic tree based on nuclear ribosomal ITS, and a plastid DNA phylogeny based on three intergenic spacers (trnS-trnG, ndhF-rpl32, and trnQ-rps16). In total, both nuclear and plastid phylogenetic analyses include more than 70 samples of 39 species from 27 countries, which represent close to 60% of the diversity of the genus. Two complementary trees, based only on one plastid marker, are also included. The first, based on trnS-trnG, is used to increase the number of species related to T. amplexicaulis. The second, based on ndhF-rpl32, is used to investigate the separation between T. tetrandra and T. parviflora. The incongruence between the available infrageneric classifications and the molecular results is confirmed. A reticulate evolution is inferred from the trees, showing characters such as vaginate leaves appearing at different stages along the evolutionary history of the genus. The presence of T. canariensis outside the Canary Islands is cast into doubt, and all such records from NW Africa and Europe are here considered to belong to T. gallica. The results also suggest independence of T. karelinii from T. hispida, and T. parviflora from T. tetrandra. Relationships between a number of species are still not resolved, and additional studies will be needed to further refine the complex taxonomy of Tamarix.

“…The flora of Morocco still brings new discoveries due to its climatic and topographical diversity, and the complexity of its territory. Since the publication of the last volume of the Flore Pratique du Maroc (Fennane et al, 2014), more than 30 new species have been described (Alonso et al, 2015;Andrés-Sánchez et al, 2015;Brullo et al, 2015Brullo et al, , 2017Chambouleyron et al 2015;Dobignard, 2015;Talavera et al, 2015;Vigalondo et al, 2015;Crespo et al, 2016;Sutorý, 2016;Gonçalves, 2018;Gutiérrez-Larruscain et al, 2018;Khamar et al 2018;Martínez-Laborde, 2018;Mejías et al, 2018;Hassemer, 2019;Koch & Lemmel, 2019;Chatelain et al 2020;Martínez Labarga & Ferrer-Gallego, 2020;Vicente et al, 2020;Frankiewicz et al, 2021;Homrani-Bakali & Susanna, 2021Romo, 2021;Barone et al, 2022).

Phlomis lychnitis se registra por primera vez en el continente africano. Hasta el momento, sólo se conoce de Marruecos en el Alto Atlas Oriental. Se proporciona una descripción de la especie, así como los primeros datos sobre su ecología en Marruecos junto con su distribución geográfica y caracteres diagnósticos con la especie morfológicamente más cercana que comparte flores de color amarillo. También se proporcionan fotografías y una clave actualizada de las especies de Phlomis en Marruecos.

“…However, Filago pyramidata L. is difficult to confuse with species of the same genus, since, in the seedling stage, it is more similar to species of the genus Allyssum (Brasicaceae) [11]. This weed germinates in autumn-winter, forming dense rosettes, and, between March and July, it emits prostrate or erect flower stems up to 40 cm [12]. Filago pyramidata is widely distributed in Andalusia and grows both in open areas such as roadsides, clearings in the forest or scrub, as well as in cultivated areas [13], such as olive groves.…”

Filago pyramidata Tolerant to ALS-Inhibiting Herbicides: A New Invasive Weed in Olive Groves of Southern Spain

et al. 2023

Weeds that usually grow in non-agricultural areas have become increasingly common invading perennial crops. Species of the genus Filago, in addition to invading Spanish olive groves, have developed certain levels of natural tolerance to the acetolactate synthase (ALS) inhibiting herbicide flazasulfuron. The objective of this study was to determine the level and the mechanism involved in the tolerance to flazasulfuron in Filago pyramidata L., which occurs in olive groves of southern Spain, as well as to identify possible cross- or multiple-tolerances by evaluating alternative herbicides for its control. A population resistant (R) to flazasulfuron and a susceptible (S) one of Conyza canadensis were used as references. The accessions of F. pyramidata presented LD50 values (from 72 to 81 g active ingredient (ai) ha−1) higher than the field dose of flazasulfuron (50 g ai ha−1), being 11–12.5 times more tolerant than the S population of C. canadensis, but less than half the R population (170 g ai ha−1). Enzymatically, F. pyramidata was as sensitive to flazasulfuron (I50 = 17.3 μM) as the S population of C. canadensis. Filago pyramidata plants treated with flazasulfuron, combined with 4-chloro-7-nitro-2,1,3-benzoxadiazole, had a growth reduction of up to 85%, revealing the participation of glutathione-S-transferases in herbicide metabolism. Filago pyramidata presented cross-tolerance to the different chemical groups of ALS inhibitors, except triazolinones (florasulam). Synthetic auxins (2,4-D and fluroxypyr) presented good control, but some individuals survived (low multiple resistance). Cellulose synthesis, 5-enolpyruvylshikimate-3-phosphate, 4-hydroxyphenylpyruvate dioxygenase, protoporphyrinogen oxidase, photosystem I, and photosystem II inhibitor herbicides, applied in PRE or POST-emergence, presented excellent levels of control of F. pyramidata. These results confirmed the natural tolerance of F. pyramidata to flazasulfuron and cross-tolerance to most ALS-inhibiting herbicides. The mechanism involved was enhanced metabolism mediated by glutathione-S-transferases, which also conferred low multiple tolerance to synthetic auxins. Even so, herbicides with other mechanisms of action still offer excellent levels of control of F. pyramidata.
