Using cheilanthoid ferns, we provide an example of how DNA barcoding approaches can be useful to the horticultural community for keeping plants in the trade accurately identified. We use plastid rbcL, atpA, and trnG-R sequence data to demonstrate that a fern marketed as Cheilanthes wrightii (endemic to the southwestern USA and northern Mexico) in the horticultural trade is, in fact, Cheilanthes...

This paper deals with the analysis of phytoplankton composition and abundance from four sampling stations at the polymictic system, Rinc6n del Bonete water reservoir in Uruguay. Sampling data were obtained in 4 seasonal periods between February and November 1993. A hundred and twenty-four taxa were identified, where Aulacoseira granulata (Ehrenb.) Simon., A. granulata var. angustissima (Muller)...

—The diatom flora of selected sites in the Animas River Watershed, San Juan County, Colorado, was studied. Eighty diatom taxa were identified from 10 sites: 8 sites on the Animas River and 1 site each on the Cement and Cascade tributaries. The sample diatom abundance was dominated by Achnanthidium minutissimum, Encyonema silesiacum, Aulacoseira distans, Hannaea arcus, and Diatoma mesodon. The p...

F. elatior, Puccinellia distans, Lotus strictus have been tested at 4 different water table depths which grow under natural conditions in salt-affected soils of arid and semi-arid regions. The trial was carried out for 3 years with split plots test design randomized blocks. salt concentration the groundwater where irrigation has made between 3.1-4.4 dS m-1. effect on dry grass yields cultivars ...

Herbal medicines or natural products and plant extract may exhibit promising alternatives supplements for chemotherapy antibiotic therapy. The aim of the study is to evaluate therapeutic value phytoconstituents whole plant, Nepeta distans. methanol contains four known compounds, namely, oleanolic acid, ursolic β-sitosterol, stigmasterol. structures these compounds were confirmed with help NMR m...
