The genus Triphora (Triphoreae, Orchidaceae) in Colombia

Pubblicato online: 11 Mar 2015
Pagine: 1 - 5

Astratto

Abstract

In Colombia, four species of Triphora (Orchidaceae) are recognized. Two species (Triphora galeanoi and T. vichadaensis) are newly described. As circumscribed here, the two new species occur exclusively in Colombia apart from T. foldatsii, being known from Colombia and Venezuela, and T. gentianoides, ranging from the USA (Florida) in the north to Colombia in the south. For the species treated, a taxonomic description, synonymy and information about distribution are provided. Additionally,for the two new species, illustrations of flower parts are provided. A key for the determination of the Colombian species of Triphora is included.

Berberis karnaliensis Bh. Adhikari (Berberidaceae): a new addition to the Flora of India

Pubblicato online: 11 Mar 2015
Pagine: 7 - 10

Astratto

Abstract

Berberis karnaliensis Bh. Adhikari, a recently described species was recorded for the first time from the Indian territory. Hence, it is being reported herewith as an addition to the Flora of India. The species differs from its closely related taxon viz. Berberis jaeschkeana Schneid. var. usteriana Schneid. in having coriaceous leaves and 5-6 primary veins on each side of the midrib. Detailed information on taxonomy, morphology, habitat, ecology and distribution of B. karnaliensis as well as photographs and illustrations are provided here for the species identification.

Rediscovery of Jasminum parkeri Dunn, an endemic and endangered taxon from the western Himalaya, India

Pubblicato online: 11 Mar 2015
Pagine: 11 - 16

Astratto

Abstract

The present article deals with the rediscovery of Jasminum parkeri Dunn (Oleaceae) collected from its type locality after a lapse of about 100 years. J. parkeri is a highly endangered and narrowly endemic taxon restricted to a small pocket in the remote mountain area of Chamba district, Himachal Pradesh in the western Himalaya, India. In order to facilitate identification of this species, the plant description along with a brief history of its discovery, affinity with the other taxa of Jasminum, ecological notes, and pictures are provided. Subsequently, possibility of cultivation of this species in ex-situ conditions is also discussed.

Orobanche lutea Baumg. (Orobanchaceae) in Poland: revised distribution, taxonomy, phytocoenological and host relations

Pubblicato online: 11 Mar 2015
Pagine: 17 - 39

Astratto

Abstract

The paper presents current distribution of Orobanche lutea Baumg. in Poland based on a critical revision of herbarium and literature data as well as results of field investigations conducted between 1999-2014. Majority of localities are centred around the Silesia-Cracow, Małopolska and Lublin-Lviv Uplands. The greatest density of sites with probably the most abundant populations in Europe is in the central part of Silesia-Cracow Upland, which, by several hundred years, was heavily exploited for calamine mining (rich in zinc, lead and silver). This resulted in the formation of large areas of gangue containing toxic heavy metals. Since limestone, dolomite, marl and postglacial calcareous clay and sands occur there in most places, the soil is often strongly calcareous. Populations of O. lutea contain here many thousands of shoots. The distribution of the species in Poland is mapped. The taxonomy, biology, ecology and threats are also discussed.

Orobanche flava (Orobanchaceae) in Poland: current distribution, taxonomy, hosts and plant communities

Pubblicato online: 11 Mar 2015
Pagine: 41 - 52

Astratto

Abstract

Orobanche flava is a species of Central European mountain ranges, mainly the Alps and Carpathian Mts. The paper presents the current distribution of O. flava in Poland based on a critical revision of herbarium and literature data as well as results of field investigations conducted between 1999 and 2014. The distribution of species is centered in southern Poland, mainly in the Carpathian Mts., and, sporadically, in the Sudeten Mts. The distribution of O. flava in Poland is mapped. The taxonomy, biology, and ecology are also discussed.

Small-scale spatial analysis of river corridor plants distribution in the San River valley (SE Poland)

Pubblicato online: 11 Mar 2015
Pagine: 53 - 64

Astratto

Abstract

Spatial distribution and habitat preferences of 55 river corridor plant species were analyzed on a local scale in the valley of a medium-size regulated river. The analysis was based on the results of a detailed mapping on a 50 km-long section of the Lower San River valley (366 cartogram cells of 1 square km). Selected species were divided into two groups: (1) strictly and (2) loosely confined to river corridors. River corridor plants were found throughout the valley (river channel, active and historical floodplain, older terraces, slopes); however, their frequency was diverse in particular areas. The highest concentrations were observed on the floodplain. Their number decreased towards the border areas of the valley. Species which were less confined to rivers were found more frequently in the valley (one species occupied, on average, 12.9% of grid cells), than plants strictly confined to the river system (one species occupied, on average, 5.9% of grid cells); however, the ranges of species of the second group were more restricted to the Holocene part of the valley, especially to the floodplain. River corridor plants were, ecologically, a highly diversified group. In the San river valley, they were found in riparian forests, pioneer ephemeral communities on the banks of water bodies, dry grasslands, meadows and old river beds; a lot of them grew in ruderal habitats.

Seed banking of Polish endangered plants – the FlorNatur Project

Pubblicato online: 11 Mar 2015
Pagine: 65 - 72

Astratto

Abstract

Among the 2750 species of the Polish vascular flora, about 500 species are threatened with extinction and 430 of them are strictly protected by national law. The FlorNatur project for the ex situ conservation of the most endangered species was started in 2009. The aim of the project is to collect seeds of 61 species from 161 sites in eastern Poland and store them in the Seed Bank of the Polish Academy of Sciences Botanical Garden - Center for Biological Diversity Conservation in Warsaw- Powsin. A complementary program is being carried out by the Forestry Gene Bank at Kostrzyca in western Poland. Their task is to collect 58 species from 129 natural sites in the western part of Poland. To date, seeds of 31 species from 56 populations have been collected, tested and stored in liquid nitrogen.
