Notulae to the Italian native vascular flora: 5
2018
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records and confirmations to the Italian administrative regions for taxa in the genera Allium, Arabis, Campanula, Centaurea, Chaerophyllum, Crocus, Dactylis, Dianthus, Festuca, Galanthus, Helianthemum, Lysimachia, Milium, Pteris, and Quercus. Nomenclature and distribution updates, published elsewhere, and corrections are provided as supplementary material.
Patterns of flower development in Apiaceae–Apioideae
2016
Abstract Apiaceae is a large family characterized by uniform flowers. However, early ontogenetic studies revealed unexpected diversity in flower development. In the present paper, we investigate eight species representing six tribes of subfamily Apioideae to address diversity in developmental patterns. One focus is on the developmental divergence of sex morphs in andromonoecious species. Scanning electron microscopic studies were conducted on six herbaceous species: Chaerophyllum bulbosum , Daucus carota , Dorema aucheri , Ferula hezarlalehzarica , Orlaya grandiflora , Pastinaca sativa , and two woody species, i.e., Bupleurum fruticosum and Seseli ghafoorianum . Our results confirm the exis…
Andromonoecy and developmental plasticity in Chaerophyllum bulbosum (Apiaceae–Apioideae)
2013
Background and Aims: Andromonoecy, the presence of hermaphrodite and male flowers in the same individual, is genetically fixed or induced, e.g. by fruit set. Little is known about the forces triggering andromonoecy in the Apiaceae. In the present study, a natural population of the protandrous Chaerophyllum bulbosum was investigated to elucidate architectural constraints and effects of resource reallocation. Methods: Three sets of plants (each n ¼ 15) were treated by hand pollination, pollinator exclusion and removal of low-order inflorescences. Fifteen untreated plants were left as controls. Key Results: Untreated plants produce umbels up to the third branch order, with increasing proportio…
