“…Despite its wide host range in coastal areas, it occurs nearly exclusively on E. maritimum in Ammophila arenaria communities on mobile dunes (Hipkin ). On Menorca, O. iammonensis similarly parasitizes E. maritimum (Pujadas‐Salvà & Fraga I Arguimbau ). O. amethystea var.…”

Summary1. This account presents information on all aspects of the biology of Eryngium maritimum L. (Sea Holly) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. 2. Eryngium maritimum is a native perennial hemicryptophyte, with a large taproot, spiny and leathery leaves and a pale bluish inflorescence. It has a more or less continuous distribution in suitable habitats along the coasts of Great Britain and Ireland up to about 55°N, but it is more scattered further north. On the west coast, it is found south of the Hebrides, and on the east coast, with some exceptions, south of Yorkshire. In Europe, it has a wide, but mainly southern temperate, European distribution along the coasts of the Atlantic Ocean, the Baltic, the Mediterranean, and the Black and Azov Seas. Its northern distribution limit is at c. 60°N. 3. Eryngium maritimum grows typically on sand and shingle beaches, foredunes and yellow dunes, as well as in semi-fixed grey dunes. Its habitats have full sunlight and are more or less dry. It occurs in many coastal plant communities from the beach inland, and because of its wide European distribution, it occurs with members of several different biogeographical species groups. 4. Protected from grazing by its spininess and sclerophylly, E. maritimum is nevertheless vulnerable to direct damage by trampling. It supports few insect herbivores, probably because of chemical defences. Historically, it has had a great number of medicinal uses. 5. Eryngium maritimum is unable to withstand competition from faster and more densely growing plant species. In many coastal regions, in both temperate and mediterranean parts of Europe, it is one of the rarest and most threatened plant species, mainly because of habitat loss and land-use changes.Key-words: climatic limitation, communities, conservation, ecophysiology, geographical and altitudinal distribution, germination, herbivory, mycorrhiza, reproductive biology, soils Sea Holly.

“…Recent approaches have shown a greater tendency than the earlier conservative treatment of Chater & Webb (1972) to treat host specific races within the genus as distinct species, these often demonstrating both a narrow geographical and host range. This has led to a spate of new species being described in the Mediterranean, Asia Minor and the Middle East in the last two decades (see for example: Pujadas-Salva & Crespo, 2004;Pujadas-Salva et al, 2005, Pujadas-Salva et al, 2008Domina & Danin, 2014;Zare & Dönmez, 2014;Piwowarczyk, 2015). Delineating taxa objectively and reliably is important for informing ecological surveys and for setting conservation priorities: for example in the British Isles, the native subsp.…”

Common broomrape (Orobanche minor Sm.) is the most widespread and variable species in the British Isles and is the subject of much taxonomic confusion. Poor preservation in herbaria, coupled with the presence of cryptic host-specific races, have contributed to this. Here we review the taxonomic status of infraspecific taxa of O. minor in the British Isles, and provide a revised identification key, informed by morphology, ecology and molecular data. We describe two new varieties of O. minor s.l. that are ecologically distinct and discuss within the broader context of cryptic taxa in the subsection Minores (Beck-Mannagetta) Teryokhin in the British Isles and continental Europe. We suggest that delineating taxa objectively and reliably will be important for informing conservation priorities. Host identity and ecology, besides morphology, are essential considerations when identifying infraspecific taxa in this taxonomically challenging species.

Taxonomic traits in the microstructure of flowers of parasitic Orobanche picridis with particular emphasis on secretory structures

Orobanche picridis is an obligate root parasite devoid of chlorophyll in aboveground organs, which infects various Picris species. Given the high level of phenotypic variability of the species, the considerable limitation of the number of taxonomically relevant traits (mainly in terms of generative elements), and the low morphological variation between species, Orobanche is regarded as one of the taxonomically most problematic genera. This study aimed to analyse the taxonomic traits of O. picridis flowers with the use of stereoscopic and bright-field microscopy as well as fluorescence, scanning, and transmission electron microscopy. The micromorphology of sepals, petals, stamens, and pistils was described. For the first time, the anatomy of parasitic Orobanche nectaries and the ultrastructure of nectaries and glandular trichomes were presented. Special attention was paid to the distribution and types of glandular and non-glandular trichomes as well as the types of metabolites contained in these structures. It was demonstrated that the nectary gland was located at the base of the gynoecium and nectar was secreted through modified nectarostomata. The secretory parenchyma cells contained nuclei, large amyloplasts with starch granules, mitochondria, and high content of endoplasmic reticulum profiles. Nectar was transported via symplastic and apoplastic routes. The results of histochemical assays and fluorescence tests revealed the presence of four groups of metabolites, i.e. polyphenols (tannins, flavonoids), lipids (acidic and neutral lipids, essential oil, sesquiterpenes, steroids), polysaccharides (acidic and neutral polysaccharides), and alkaloids, in the trichomes located on perianth elements and stamens.
