Abstract The forest canopy, as a biodiversity hotspot with many wildlife habitats, remains difficult site to access for researchers and managers. Here, we present novel, small, unmanned aerial vehicle, called the Druid Drone (DD), equipped multifunctional manipulator designed tree crown management research. Its use is demonstrated by studies control of widespread, obligatory hemiparasitic European mistletoe ( Viscum album L.). DD provides integrated pest canopy surveying, spraying sampling...

The hemiparasitic European mistletoe, Viscum album L. (Viscaceae), displays a rapid and remarkable expansion into natural urban ecosystems in Ukraine. monitoring management of this quickly spreading species is becoming increasingly difficult as new plant become hosts. Unlike other local mistletoe species, the has broad distribution thus requires countrywide pest status assessment for control. This review outlines major taxonomic evolutionary issues pertinent to V. with an emphasis on...

In this paper, we propose a new replacement name “Viscum meyeri” for southern African endemic species currently known as V. anceps E.Mey. ex Sprague. The latter is unavailable use, being illegitimate later homonym of Spreng.—the basionym the presently accepted Phoradendron (Spreng.) M.Gómez. addition, second-step lectotypification and replaced names conducted. One collection from K designated here lectotype meyeri (≡ Sprague), eight more collections FR, HAL, HBG, K, P, S are considered isolectotypes.

Abstract Mistletoes, as perennial hemiparasitic angiosperms that parasitize woody plants, are an important component of the highly diverse, endemically rich and mosaic African flora, which is attributed to Holarctic, Paleotropical, Cape Floristic kingdoms. The richness mistletoes from Loranthaceae Viscaceae, along with many aspects their biology ecology, was covered in comprehensive monograph Polhill Wiens (1998, Mistletoes Africa , Royal Botanic Gardens). present review devoted taxonomic...

The paper presents a taxonomic and nomenclatural account on four taxa of Thymus published by Ukrainian monographers the genus M.V. Klokov (1896–1981) N.O. Desjatova-Shostenko (1889–1968), namely Th. dimorphus [unranked] steppaceus, eltonicus, kirgisorum var. creticola, pulegioides subsp. ucrainicus. Based original material examination, lectotype from herbarium CWU is designated for each name. Several changes are proposed, including treatment steppaceus as synonym dimorphus, eltonicus...

Avena laevigata Schur (1860: 72) belongs to the taxonomically difficult group of perennial oats whose phylogenetic relationships, systematics, and nomenclature have been reconsidered many times (Holub 1958, 1962, Gervais 1973, Röser 1989, Lange 1995, Conti et al. 2005, 2009, Romero-Zarco 2011). It is affiliated with generic name Avenula (Dumortier 1824: 122) Dumortier (1868: 68), a taxon accepted in worldwide classification Poaceae (Soreng 2015) basionym subspecies pubescens (Hudson 1762:...

The Balkan species Thymus jankae is documented for the first time from Ukraine on Mount Chorna Hora (Vynohradiv town, Transcarpathian region), which ca. 300 km northwards its main range. This locality has long been overlooked due to misidentification of early collections with other taxa. Despite ambiguous taxonomy, available morphological, caryological, biogeographical, and molecular data support a rank Th. suggest ancestral position within praecox-group. Morphology chromosome count (2n =...

The hidden lifestyle of the holoparasitic perennial Lathraea squamaria L. (common toothwort), which parasitizes roots deciduous trees in forests and woodlands, has led to significant knowledge gaps about mechanisms underlying this plant symbiotic interaction. Here we present first detailed structural examination interface between its host root belowground using non-destructive micro-computed tomography (micro-CT). To clarify physiology seed germination elusive species, demonstrated efficient...

One of the main issues plant cultivation in botanical gardens is correct identification species and availability their valid names. Ficus L. one most troublesome genera this respect due to its morphological variability inconstancy classification. In order verify correctness scientific names provided Ukrainian gardens, we conducted these plants along with determi­ning taxonomic status, features, natural distribution. The leaves shoots were sampled Lviv, Kyiv, Donetsk cities during 2009–2013....

Salvia transsylvanica is regarded to be endemic the Transylvanian Basin, Eastern and Southern Carpathians in Romania. In natural habitats, it easily intercrosses with other sage species, such as S. nemorosa, nutans, pratensis, hybrids described nothospecies ×hybrida, ×telekiana, ×bichigeanii, respectively. One specimen from GOET designated here a lectotype of pratensis var. transsylvanica, basionym transsylvanica. addition, three specimens LW, BP, BUCA are lectotypes for hybrid names. Main...

In this paper, some nomenclatural and taxonomic questions on Salvia dumetorum are discussed in order to avoid confusion the use of its name. One collection from LECB is designated as a lectotype S. dumetorum. Based complex diagnostic features, it proposed consider separate species which distinct close relative pratensis.

The protologue, original material and typification of the Linnaean name Thymus pulegioides (Lamiaceae) are discussed. specimen Herb. Linnaeus No. 38.5 (LINN) has been regarded as lectotype T. pulegioides, perfectly agrees with protologue this name, but appears not to have effectively designated such. Therefore, must be 38.6 (LINN), which was by Mártonfi in 1997.Citation: Nachychko V. O. & Sosnovsky Y. 2020: What is (Lamiaceae)? – Willdenowia 50: 23–27. doi:...

Thymus ×porcii is a natural hybrid between T. pannonicus and pulegioides, occurring within the co-occurrence range of its parental species in forest forest-steppe zones Europe. Taxonomy nomenclature this present longstanding puzzle due to lack critical evaluations original material as well conflicting taxonomic interpretations parent taxa both at specific intraspecific levels. The paper attempts clarify these issues, arguing against synonymic treatment and/or consolidation which accepted...

Chron., ser. 2, 19: 404. 31 Mar 1883 [Angiosp.: Ar.]. was published (Anonymous 1883) as the name of a new species collection William Bull (1828–1902), famous English nurseryman and rare plant merchant, which to be presented his forthcoming retail list for (e.g., 304. 1883). Since its publication, this has been commonly use by horticulturists, denoting commercially popular ornamental houseplant cultivated around world (although misspelled...

Abstract The obligate root parasite Cistanche armena is a recently rediscovered, extremely rare endangered species endemic to Armenia, specifically parasitizing camelthorn ( Alhagi maurorum , Fabaceae) and saltwort Salsola dendroides Chenopodiaceae). Its populations are reputedly declining due habitat destruction biotic impacts. Since the only known means of its reproduction via seeds, understanding mechanisms breaking C. seed dormancy germination along with related aspects species’ biology...

Mistletoe detection and sampling remain challenging for arborists, dendrologists, forest ecologists, other specialists because of the limited access to host tree canopy. In this review, smart solutions mistletoe based on airborne platforms are discussed. Airborne remote sensing (ARS) has developing potential provide rapid, accurate, cost-efficient research level large areas within complex terrain. Herein, such ARS methods as image spectroscopy, infrared thermography, light ranging, structure...

We discuss the typification and nomenclature of name Rhododendron ×intermedium (Ericaceae). As R. Wenderoth is invalid, earliest legitimate for ferrugineum × hirsutum hybrid published by Tausch. designate one collection from PRC as lectotype two other specimens are considered to be a part original material. A list synonyms provided IBF designated neotypes heterotypic synonyms, namely ×halense ×hirsutiformum.
