Abstract:
A new species of Orobanche is described from the Canary Islands. The plant belongs to the complicated Subsection Minores and has a distinct combination of morphological features, ecology, and host specificity. The markedly cernuous corolla, high filament insertion and colouration distinguishes Orobancheandryalae from closely related species with which it has been previously confused, and which do not occur in the Canary Islands, including O.amethysteasubsp.castellana and O.calendulae; these features remain stable in cultivation. Orobancheandryalae appears to be parasitic almost exclusively on Andryala spp., and occurs on thermophilus volcanic substrates in northern Lanzarote, northwest Tenerife and Jandía in Fuerteventura. An updated key to the Orobanche of the Canary Islands is presented, including the new taxon we describe here.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
