This new species occurs in the northwest region of Argentina, in Salta, Jujuy and Tucumán Provinces, in the Yungas biogeographical province. It is usually found on rocky and sandy soils, as well as along riverbanks. Porophyllum riparium is characterized by being an annual or short-lived perennial, glaucous, odoriferous, monoecious herb, 15–80(–130) cm tall, with sessile or attenuate into a pseudopetiole, linear-elliptic leaves with submarginal and subapical semi-pellucid oil cavities, lemon-colored infundibuliform corollas and exserted brownish anthers. Additionally, female plants of Porophyllum cabrerae were documented for the first time, photographs and descriptions of their female florets are included. Also, a key to identify northwestern species of Porophyllum is provided.","PeriodicalId":506155,"journal":{"name":"Phytotaxa","volume":"8 33","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141642512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of its species can be characterized by long-pedunculate radiate capitula, campanulate involucre, epaleaceous or partly paleaceous receptacle, strigose or glabrous cypselae, and pappus scales 0.1–1.5 mm long. In order to improve our understanding of this series, we generated a nomenclatural synopsis, revising protologues and type material. We propose 6 lectotypifications and 1 neotypification.

Huang, Y.C. Zhong et Z.F. Lu, in the sand habitat. However, field investigations and population sampling in these two habitats revealed a certain degree of morphological transition and variation among the populations.

The MLtree strongly supports the Rivina humilis clade, which includes R. bengalensis and R. humilis var. bracteata. The synonymization of R. bengalensis is supported by both molecular and morphological data. The accessions of Rivina humilis var. bracteata group together in the R. humilis clade, but the results also show inter-population variation, which primarily supports the varietal status of the taxon. The broadly oblanceolate bracts which is abruptly narrowed from middle or above middle into a long subulate to narrowly triangular, acuminate apical lobe make the variety distinct from typical R. humilis.

Wild plants can roam freely across international borders. From September 2021 to June 2023, 45 field excursions were made to Egypt’s southern Nile Islands in the Aswan Governorate to undertake vegetation surveys. Depending on the literature reviewed and herbaria consulted during this study, three plant taxa, as well as one additional genus (Macroptilium), found during these field excursions were not previously recorded in the Egyptian Flora. These new records are Acanthospermum hispidum (Asteraceae), Geranium carolinianum (Geraniaceae), and Macroptilium atropurpureum (Fabaceae). These plants are classed as noxious weeds that harm agriculture. A complete description, occurrence and distribuion maps, plant photos and illustrations are provided. This study underlines the importance of carrying out extensive and ongoing research on the flora of Aswan’s Nile Islands to have a better knowledge of flowering plant distribution patterns.
