Boris Zimmermann
FTIR microspectroscopy, in combination with spectral averaging procedure, enables precise analysis of pollen grains for chemical characterization and identification studies of fresh and fossilised pollen in botany, ecology and palaeosciences. Infrared microspectroscopy (µFTIR) of Pinaceae pollen can provide valuable information on plant phenology, ecophysiology and paleoecology, but measurements are challenging, resulting in unreproducible spectra. The comparative analysis of µFTIR spectra belonging to morphologically different Pinaceae pollen, namely bisaccate Pinus and monosaccate Tsuga pollen, was conducted...

Many municipalities are setting ambitious tree canopy cover goals to increase the extent of their urban forests. A historical perspective on urban forest development can help cities strategize how to establish and achieve appropriate tree cover targets. To understand how long-term urban forest change occurs, we examined the history of trees on an urban college campus: the University of Pennsylvania in Philadelphia, PA. Using a mixed methods approach, including qualitative assessments of archival records (1870-2017), complemented by quantitative analysis of tree cover from aerial imagery (1970-2012), our analysis revealed drastic canopy cover increase in the late 20th and early 21st centuries along with the principle mechanisms of that change...

Cris Kuhlemeier
Leaves and flowers are arranged in regular patterns around the stem of a plant, a phenomenon known as phyllotaxis. Different arrangements occur, such as distichous, decussate or spiral (Figure 1). Most prevalent in nature are spirals in which the average divergence angles between successive organs are close to 137.5°, the so-called 'golden angle'. It is this exact number that has given phyllotaxis its special flavor as a quantitative developmental problem, and over the centuries, it has enjoyed the attention of scientists far beyond botany...

On January 12(th) 1877, the Grim Reaper visited Wilhelm Hofmeister (Figure 1) for the last time. Having recently witnessed the death of a wife, two daughters, and two sons (only two of his nine children survived him), the German botanist, perhaps succumbing to the weight of his own grief, suffered a series of strokes and then promptly died at the age of 52 in Lindenau, Germany. He has since faded into the dusty annals of 19(th) century botany, his contributions to our knowledge about plants, how they come into being, develop and interact with their environment, mostly forgotten...

Forensic botany can provide useful information for pathologists, particularly on crime scene investigation. We report the case of a man who arrived at the hospital and died shortly afterward. The body showed widespread electrical lesions. The statements of his brother and wife about the incident aroused a large amount of suspicion in the investigators. A crime scene investigation was carried out, along with a botanical morphological survey on small vegetations found on the corpse. An autopsy was also performed...

Masao Ota was a Professor of Dermatology at Tokyo Imperial University. He is known to dermatologists around the world as the researcher who identified Nevus of Ota. He is also known for his research on Hansen's Disease. He was critical of the forced isolation policy and the sterilization law. He dreamt of developing chemotherapeutic measures and dedicated himself to cultivating Mycobacterium leprae. Among his accomplishments, those in the area of medical mycology are particularly remarkable. His discovery of Microsporum ferrugineum, his proposal for Trichophytia pompholyciformis, and his work on Ota-Langeron taxonomy based on the findings on fungus colonies are highly regarded and earned him the Ordre Royale de la Legion D'honneur...

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Psiadia Jacq. ex. Willd. belongs to the Asteraceae family and includes more than 60 species. This genus grows in tropical and subtropical regions, being especially well represented in Madagascar and the Mascarene Islands (La Réunion, Mauritius and Rodrigues). Several Psiadia species have been used traditionally for their medicinal properties in Africa and the Mascarene Islands. Based on traditional knowledge, various phytochemical and pharmacological studies have been conducted...

Principle 2 of the Prokaryotic Code, as modified by the ICSP in 1999, reads: 'The nomenclature of prokaryotes is not independent of botanical and zoological nomenclature. When naming new taxa in the rank of genus or higher, due consideration is to be given to avoiding names which are regulated by the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi and plants'. But in the current version of the Prokaryotic Code no Rule implements this version of Principle 2...

ETHNOPHARMACOLOGICAL RELEVANCE: Plants of the genus Cimicifuga have long been used as an ethnomedicine in China, Europe, and North America for its high medicinal value and health benefits. Their dried rhizomes are widely used for treating wind-heat headache, toothache, aphtha, sore throat, measles, spot poison, archoptosis, and uterine prolapse. In addition, it is used as a dietary supplement for preventing women menopausal symptoms and osteoporosis. AIM OF THE REVIEW: This paper aims to provide up-to-date information on the genus Cimicifuga, including botanical characterization, medicinal resources, traditional medicinal uses, phytochemistry, quality control, pharmacological research as well as the toxicology...

What do you think of when you think of taxonomy? An 18th century gentlemen in breeches? Or perhaps botany drawings hung on the walls of a boutique hotel? Such old-fashioned conceptions to the contrary, taxonomy is alive today although constantly struggling for survival and recognition. The scientific community is losing valuable resources as taxonomy experts age and retire, and funding for morphological studies and species descriptions remains stagnant. At the same time, organismal knowledge (morphology, ecology, physiology) has never been more important: genomic studies are becoming more taxon focused, the scientific community is recognizing the limitations of traditional "model" organisms, and taxonomic expertise is desperately needed to fight against global biodiversity declines resulting from human impacts...

In Valencia Region (Spain), some wild and cultivated sages are used for medicinal purposes. Among them, Salvia officinalis subsp. lavandulifolia (SL) is widely employed and known for production of Spanish sage oil and herbal products. Nevertheless, it shares the market with S. blancoana subsp. mariolensis (SB) and, to a lesser extent, with their hybrid S. x hegelmaieri (SH). The knowledge on these two species is far low and confusion between them is possible. The aim of the present paper is to improve the ethnopharmacological, morphological and chemical knowledge of these sages, and to contribute to setting up quality specifications for improving identification and distinction from other Salvia species, such as, S...

This paper explores how João de Andrade Corvo and José Vicente Barbosa du Bocage, two nineteenth-century Portuguese naturalists, were able to reach prominent political positions in their country by means of their work in, respectively, botany and agriculture, and zoology. The authority they derived from their scientific activities and the knowledge they acquired in the process, favored by their proximity to particular political quarters, elevated them to important governmental offices, in the context of which they implemented policies that reinforced Portugal's identity as an imperial nation...

BACKGROUND: Several medicinal properties have been reported for plants in the genus Evolvulus, such as a brain tonic and antifungal from Evolvulus alsinoides, and a sedative and an anthelmintic from Evolvulus nummularius. Therefore, the correct identification of the source plants is critically important. The aim of this research was to investigate the micromorphology of two Evolvulus taxa used for herbal medicines compared with one worldwide ornamental species by using peeling, paraffin embedding, acetolysis, and SEM methods in order to support species identification...
