Hyptidendron Harley, one of the 19 genera recognized for subtribe Hyptidinae, has some its species with a narrow campos rupestres (a Brazilian vegetational formation) distribution, often restricted to single mountain range. We report new species, pulcherrimum Antar & sp. nov., endemic in Serra do Padre Ângelo, disjunct area from where angiosperm have been recently described. The is unique due m...
A new species of Spigelia L. (Loganiaceae), Spigelia genuflexa Popovkin & Struwe, sp. n., from the Atlantic forest of northeastern Bahia, Brazil, is described, being the first reported geocarpic species in the family. During fruit maturation, the basal infructescences bend down towards the ground, depositing the fruit on the surface (and burying it in soft kinds of ground cover, e.g., moss), wh...
Trichome Micromorphology of Egyptian Ballota (lamiaceae) with Emphasis on Its Systematic Implication
Trichomes of 5 taxa of the genus Ballota were examined by using light and scanning electron microscopy. The indumentum shows considerable variability among different species, and therefore, affords valuable characters in delimitation of species. The characters of taxonomic interest were presence of glandular and non-glandular trichomes, number of cells (uni-, bi-, trior multi-cellular), presenc...
A comparative carpological study of 96 species of all clades formerly considered as the tribe Chenopodieae has been conducted for the first time. The results show important differences in the anatomical structure of the pericarp and seed coat between representatives of terminal clades including Chenopodium s.str.+Chenopodiastrum and the recently recognized genera Blitum, Oxybasis and Dysphania....
The taxonomical relationship between Salvia pratensis and S. bertolonii has been unclear for a long time. Salvia bertolonii has alternatively been considered a synonym, a subspecies, a problematic subspecies and a form of Salvia pratensis. However, both these two species are sometimes used in traditional medicine instead of sage (Salvia officinalis) or as an adulteration for the same drug. In o...
This article conta ined descriptions of five new taxa of Mexican Euphorbiaceae. Euphorbia (sub g. Agaloma) na yarensis is endemic to pine-oak woodland in the mount ains of central Nayarit. It appears related to E. so ob yi but differs by possessing linear to linear-ovate leaves. Croton varelae is also endemic to central Nayarit. A key was provided to distinguish this spec ies. a member of sect....
Prunus pananensis Z. L. Chen, W. J. Chen & X. F. Jin, a new species of Rosaceae from central Zhejiang, China is described and illustrated. Micromorphological characters of the indumentum on young shoots, leaves, petioles and peduncles, including scanning electron microscope [SEM] images, are provided. This new species is morphologically similar to P. schneiderianae Koehne in having its young sh...
Rätzel, S., R. Hand, C.S. Christodoulou & H. Uhlich (2021). Phelipanche chionistrae (Orobanchaceae): a new holoparasitic species from Cyprus. Candollea 76: 77–82. In English, English abstract.The (Orobanchaceae) is described Chionistra, the highest summit of Troodos range in Morphological data strongly suggest affinities to rosmarina complex, predominantly West Mediterranean taxa, and olbiensis...
Abstract Myrtaceae is a plant family with outstanding diversity in the neotropics, which species are of difficult identification. Thus, for differentiation between to be possible, targeted inventories and detailed descriptions necessary, develop accessible reliable identification tools. The goal this research quantify richness describe vegetative characters from Araucaria Rainforest remnant, th...
