•21 metabolites were detected in honey produced in southeastern and southern Brazil.•Honey were discriminated by geographic and botanical origins using 1H NMR and PCA.•Eucalyptus spp., Hovenia ...dulcis, and Citrus spp. honey were discriminated.
This study applied qNMR spectroscopy and chemometrics to metabolically profile polyfloral honey samples collected in southeastern (São Paulo - SP) and southern (Santa Catarina - SC) Brazil, over the 2019–2020 and 2020–2021 harvest seasons. Both 1D and 2D NMR experiments were carried out to identify and quantify metabolites, followed by descriptive statistical analysis, heatmap, and principal component analysis (PCA), considering geographic and botanical origins. Twenty-one metabolites were detected, encompassing carbohydrates, amino acids, organic acids, ketones, alcohols, esters, and alkaloids. The heatmap and the PCA allowed for distinguishing the geographical and botanical origin. Regarding the botanical origin, three clusters were detected, i.e., Hovenia dulcis (SC), Citrus spp. (SP), and Eucalyptus spp. (SC and SP). The analytical approach proved to be effective for determining the geographic and botanical origins of Brazilian polyfloral honey, even though the country has a huge floral diversity and, accordingly, different types of honey.
A taxonomic revision and nomenclatural update for Paspalum L., group Caespitosa are presented. The group Caespitosa consists of perennial species, usually rhizomatous, with culms simple, erect, ...inflorescences terminal, pauci-racemose, and spikelets mostly ellipsoid to ovoid or obovoid. It is distributed from the southern United States to northeastern Argentina, with several taxa concentrated in the Caribbean Islands. We recognize 13 species and three varieties (i.e., Paspalum acutifolium León, P. albidulum Henrard, P. bakeri Hack., P. blodgettii Chapm., P. caespitosum Flüggé, P. chacoense Parodi, P. divergens Döll, P. galapageium Chase var. galapageium, P. galapageium var. minoratum Chase, P. galapageium var. redundans (Chase) Delfini & Zuloaga, P. indecorum Mez, P. laxum Lam., P. ligulare Nees, P. molle Poir., and P. redondense Swallen), and designate lectotypes for three names. We propose a new synonym for P. ligulare and a new variety for P. galapageium, and provide updates on inferential lectotypifications (for seven names) and on inferential neotypification (for P. caespitosum var. longifolium). We then comment on four situations of uncertainty, and present new geographic analyses of the species. Illustrations, a key for the species, and additional comments on morphology of the group Caespitosa are also included. Este trabajo presenta una revisión taxonómica y actualización nomenclatural para el grupo Caespitosa de Paspalum L. Los taxones de Caespitosa se caracterizan por su hábito mayormente cespitoso, generalmente con rizomas, cañas simples, erectas, inflorescencias terminales, pauciracemosas y espiguillas en su mayoría elipsoides a ovoides u obovoides. El grupo se distribuye desde el sur de los Estados Unidos de América hasta el noreste de la Argentina, con varias especies concentradas en las islas del Caribe. Un total de 13 especies y tres variedades son reconocidas en el grupo (i.e., Paspalum acutifolium León, P. albidulum Henrard, P. bakeri Hack., P. blodgettii Chapm., P. caespitosum Flüggé, P. chacoense Parodi, P. divergens Döll, P. galapageium Chase var. galapageium, P. galapageium var. minoratum Chase, P. galapageium var. redundans (Chase) Delfini & Zuloaga, P. indecorum Mez, P. laxum Lam., P. ligulare Nees, P. molle Poir. y P. redondense Swallen), se han designados lectotipos para tres nombres, se propone una nueva sinonimia para P. ligulare y una nueva variedad para P. galapageium, se presentan actualizaciones sobre lectotipificaciones inferenciales (para siete nombres) y sobre una neotipificación inferencial (para P. caespitosum var. longifolium), comentarios sobre cuatro situaciones de incerteza y se presenta un nuevo análisis geográfico de las especies. También se incluye una clave de las especies, ilustraciones y comentarios adicionales sobre la morfología del grupo Caespitosa.
Pertusaria atropallida and P. uralensis are found to represent synonyms of the lichenized fungus P. coccodes. Lectotypes are selected for P. atropallida and P. uralensis.

The nomenclatural history, morphology, and typification of Utricularia triphylla Ule are discussed. We preferred to follow the current classification that the species is a synonym of U. geminiloba ...Benj., as more evidence and new conclusions will only be possible with new fresh material. A lectotype and an epitype are selected here.
New combinations for five taxa in the Hedyotis-Oldenlandia complex (Rubiaceae) in Thailand are proposed, namely Debia rosettifolia, Dimetia capitellata var. pubescens, D. prainiana, D. ridleyana and ...Scleromitrion kerrii. Six relevant taxa are lectotypified.
