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.
Studies on the genus Capparis L. (Capparaceae) in Lao PDR. V: A new species from limestones of the Luang Prabang Province
2020
A new species of Capparis L., C. lianosa Fici & Souvannakhoummane, is described and illustrated from limestones of the Muang Ngoi District, Luang Prabang Province, in northern Lao PDR. Th e new species, belonging to Capparis sect. Monostichocalyx Radlk., is related to C. zeylanica L., differing in several characters as the shorter stipular thorns, the leaves with apex acuminate, the shorter, glabrous or glabrescent gynophore and the flattened stigma.
A new species of Capparis (Capparaceae) from ultramafic substrata in New Caledonia
2017
A new species of Capparis, C. parvifolia, is described and illustrated from New Caledonia, where it is known from a few localities on Mont Kaala on ultramafic substrata. The new species is characterized by the relatively small, linear leaf-blade and by the small size of the sepals, petals, stamens, gynophore and fruit. Its affinities with related taxa are discussed and its conservation status assessed.
A taxonomic revision of the genus Capparis (Capparaceae) in New Caledonia
2017
A revision of the genus Capparis has been carried out in New Caledonia, a global biodiversity hotspot with a high rate of endemism in its vascular flora. The taxonomic treatment of Capparis in this area required study because of some incompletely known taxa and deviating forms. Based on morphological and distributional investigations carried out on historical and recent herbarium collections, four species are recognised in New Caledonia: C. spinosa, belonging to sect. Capparis; C. quiniflora, belonging to sect. Monostychocalix; and C. parvifolia and C. artensis, both belonging to sect. Busbeckea. Capparis spinosa is represented by subsp. cordifolia, a taxon widespread in several Pacific isl…
Studies on the genus Capparis L. (Capparaceae) in Lao PDR. III: A new species from the deciduous forest of the Hin Nam No National Protected Area
2018
A new species of Capparis, Capparis hinnamnoensis, is described from the Khammouan Province, central Lao PDR. The new species is characterized by the indumentum constituted by stellate, two-armed and simple hairs, and by the terminal racemes bearing trifid bracts and mediumsized flowers. It is so far known from a single locality in the Hin Nam No National Protected Area, where it has been observed in the deciduous forest on Permo-Carboniferous limestone. Its conservation status is assessed.
Evaluation of Brassicaceae seedlings as trap plants for Bagrada hilaris Burmeister in Caper bush cultivations
2020
The caper bush, Capparis spinosa (Brassicales: Capparaceae), is intensively grown on Pantelleria Island (Trapani, Sicily, Sicilian channel) where it has been granted protected geographical indication (PGI) by the EU. On this island, Bagrada hilaris, a stink bug native of Asia and Africa, is the major pest of caper crops. Recent studies have shown the attraction of B. hilaris to volatiles of brassicaceous plants at the seedling stage. The objective of this study was to evaluate three cotyledon-stage seedlings of host plants, Brassica oleracea var. botrytis (cauliflower), Eruca sativa (rocket) and Brassica carinata (Abyssinian cabbage), as potential trap plants for B. hilaris. The relative pr…
Sicilian Populations of Capparis spinosa L. and Capparis orientalis Duhamel as Source of the Bioactive Flavonol Quercetin
2023
The genus Capparis is a taxon of difficult delimitation that has several species and ecotypes due to its wide heterogeneity, its extreme phenotypic diversity, and the presence of intermediate forms linked to hybridization phenomena. The Sicilian territory hosts numerous wild and cultivated populations of two spp. Capparis spinosa L. and Capparis orientalis Duhamel, which are ecologically and morphologically distinct. The caper has considerable interest and economic value for its medicinal properties, culinary uses, and cultivation characteristics. It is one of the foods with the highest quercetin content. Quercetin is a flavonol with antioxidant, anti-inflammatory, and immunostimulant prope…
Capparaceae
2020
L’exceptionnelle richesse floristique de la Nouvelle-Calédonie est mondialement connue. Plus de 3 400 espèces de plantes vasculaires indigènes y sont répertoriées, dont les trois-quarts sont endémiques de l’archipel. L’endémisme ne concerne pas seulement les espèces, mais aussi les genres (près d’une centaine) et même trois familles. La diversité se décline aussi sur le plan écologique, en lien avec l’histoire géologique originale de la Nouvelle-Calédonie, qui a favorisé le micro-endémisme et les espèces inféodées aux substrats ultramafiques. De nouvelles espèces continuent à être découvertes, aussi reste-t-il nécessaire de poursuivre prospections et recherches botaniques, afin de mieux com…
<p><strong>Studies on the genus <em>Capparis</em> L. (Capparaceae) in Lao PDR. IV: A new species from the Khammouan Province&…
2020
A new species of Capparis, C. florida, is described and illustrated from the Hin Nam No National Protected Area, Khammouan Province in central Lao PDR. The new species, collected in forest habitats of the Khammouan karst, belongs to sect. Monostichocalyx. It is an erect shrub characterized by the widely ovate or elliptical leaf-blade, by the flowers serial in supra-axillary rows, and by the slender ovary with evident style. Its affinities with related taxa, such as the widespread C. micracantha, are discussed and its conservation status assessed.
A new species of Capparis L. (Capparaceae) from Sumatra (Indonesia)
2021
A new species of Capparis L., C. irenae Fici, sp. nov., is described and illustrated from Tigapuluh Mts., Riau Province of Sumatra, where it is known from a single locality in forest communities. The new species, belonging to Capparis sect. Monostichocalyx Radlk., is related to C. diffusa Ridl., differing in several characters as the glabrous twigs, longer petioles and leaves, flowers arranged in racemes with cataphylls at the base, longer petals hairy outside and longer filaments. Its affinities with other related taxa and its conservation status are discussed. Moreover a distribution map of the new species and an identification key to the species of Capparis recognized in Sumatra are prov…
