Pollen grain in Tamarix arborea var. arborea

2011

The diffusion in the Italian territory, as wild and cultivated plant, of T. arborea (Sieb. ex Ehrenb.) Bge. var. arborea resulted wider than us could be waited for (Venturella et al., 2007). T. arborea var. arborea is characterized by aestival inflorescences composed of racemes and vernal inflorescence simple. The racemes are not longer than 6 cm long and 5 mm broad (Baum, 1978). The species is not still well investigated from the anatomical (leaf, root and stem) and palynological point of view. Nair (1962) investigated the Indian species of tamarisks and reported for T. arborea the following concise description: prolate, 27 × 18 μm, type of pollen grains with irregular reticulum. In order …

Nomenclatural and taxonomic remarks on Prunus cupaniana (Rosaceae) from Sicily

2010

“Prunus cupaniana” is a nomen nudum doubtfully given by Gussone (1842) to some Sicilian populations close to Prunus mahaleb L. from which they are distinct by both biological and ecological characters. This name was later cited by Nyman (1878) which did not provide its validation, contrary to the erroneous IPNI report “Prunus cupaniana Guss. ex Nyman -- Consp. Fl. Eur. 1: 213. 1878 [Sep 1878]“. Fiori (1926) applied the Gussone’s epithet to the infraspecific combination “Prunus mahaleb cupaniana(Guss.)”, which is invalid being based on a nomen nudum. Before Fiori, Lojacono (1891) treated the same populations under P. mahaleb var. prostrata. Recently Raimondo & Spadaro [in Fl. Medit. 19: 309 …
