A critical form of Celtis tree (Ulmaceae) occurring in Sicily
2021
The morphological variability of the Sicilian population of Celtis australis is examined. On the basis of leaf and branching characters, recurrent in various trees growing both in natural and urban environment, a new variety is recognized and described, indicated as Celtis australis var. panormitana. The most significant differential characters and the ecology of the new taxon are reported. Finally, the taxonomic affinities with the two other conspecific taxa are recalled. At the current state of knowledge the new variety is endemic to Sicily.
Studies on the genusCapparisL. (Capparaceae) in Lao PDR
2016
Southeastern Asia is one of the main centres of diversity of the genus Capparis in the Old World. Morpho-chorological investigations carried out on collections from Lao PDR provided new data on the variation and distribution of some intrageneric taxa that were critical, poorly known or unrecorded in the country. The variability of Capparis pyrifolia and Capparis zeylanica is discussed, while Capparis acutifolia subsp. acutifolia and Capparis tenera are respectively confirmed and first recorded in Lao PDR. A new variety of Capparis micracantha is described and 12 lectotypes are designated. For each taxon morphological, chorological and autecological data are given.
