Dos nuevos híbridos en el género Thymus (Lamiaceae)

2019

Two new hybrids for the genus Thymus L.(Lamiaceae) are described; Th. ×josephi-angeli nothosubsp. occultus, nothosubsp. nov., as a result of natural crossing between Th. piperella L. and Th. vulgaris subsp. mansanetianus P.P. Ferrer & al., and Th. ×royoi, nothosp. nov., coming from the natural crossing between Th. vulgaris L. and Th. willkommii Ronniger. In addition, a lectotype of the name Thymus willkommii is designated from a specimen preserved at BC herbarium

Contribución a la quimiotaxonomía del género Artemisia L.

1987

La gran diversidad de compuestos secundarios existentes en las plantas se interpreta como una expresión típica de la vida vegetal, que representa una importante estrategia de supervivencia. Debido a la toxicidad para la misma planta producida por la acumulación de estos metabolitos, se precisan áreas especiales de deposición, lo que hace requeribles medios de transporte activo contra el gradiente de concentración para que pueda producirse este almacenamiento. Como estos requisitos, y también las vias metabólicas, están más o menos fijadas genéticamente, las diferentes tendencias de acumulación y distribución de metabolitos secundarios pueden utilizarse como criterios quimiotaxonómicos.

Sobre la descripción de Sideritis ×antonii-josephii (Labiatae)

2020

?Sideritis ×antoniijosephii? (Labiatae) was proposed in 1947 as a new hybrid by Pío Font i Quer from material collected inTeruel (Spain) on the occasion of a century dedicated to Cavanilles and distributed in an exsiccata in1947. This hybrid was proposed as the result of the natural cross between ?S. glacialis var. pulvinata? and S. hirsuta. However, the name of this hybrid, considered by some authors as validly described, is sofar an invalid name because it was not effectively published. In this work the effective publication of the description of this hybrid is carried out, specifying the identity of its parents according to the current taxonomy of the genus.

Sobre Narcissus asturiensis (Jord.) Pugsley subsp. brevicoronatus (Pugsley) Uribe-Echebarría (Amaryllidaceae) y su ubicación en el grupo Asturiensis-…

2018

A taxonomical, chorological, morphological and nomenclatural study about the so-called Narcissus asturiensis (Jord.) Pugsley subsp. brevicoronatus (Pugsley) Uribe-Echebarría and related taxa group asturiensis-minor (Amaryllidaceae) is here presented. Changes in the nomenclature of this group are proposed and keys to differentiate the three recognized subspecies are provided

Thymelaea coridifolia(Lam.) Endl. s.l., taxon ausente en el Sistema Ibérico septentrional

2018

The presence of Thymelaea coridifolia (Lam.) Endl. is discussed and denied in the northern Iberian Mountain range, which was affirmed in the treatment of the genus for Flora iberica, as a consequence of the incorrect toponimic description present in the label of the document MA 64789, which came to be the only testimony of that surprising geographical disjunction
