Rinvenimenti floristici in Piemonte

Abstract

Abstract New discoveries concerning the Piedmont Flora. – The Author's research on the Piedmont Flora – corried on from 1969 up to 1974 – led to the discovery of new stations of the following entities, that are to be considered of special interest for the Flora in Piedmont. Here they are: Cyperus strigosus L.; Scirpus atrovirens Willd.; Platanus orientalis L.; Ulmus levis Pall.; Rumex paluster Sm. (= Rumex maritimus L. var. limosus (Thuill.); Mollugo verticillata L.; Cardamine flexuosa Wth.; Diplotaxis erucoides DC.; Spiraea japonica L.; Physocarpus opulifolius (L.); Potentilla supina L.; Acer saccarinus L.; Impatiens glandulifera Royle; Euphorbia prostrata Ait.; Euphorbia humifusa W.; Sicyos angulatus L.; Cyclamen hederifolium Aiton; Erigeron karwinskyanus DC. var. mucronalus DC.; Artemisia annua L.; Siegesbekia orientalis L.; Bidens frondosa L.; Ambrosia trifida L. On the ground of the present contribution it results that some species – considered as rare or at least not very numerous in Piedmont – are probably more frequent than it was known in the past. The Author's assumption that some of them – seen along the streams – are more widely distributed should proverright.
