The traps of many carnivorous plants are red in colour. This has been widely hypothesized to serve a prey attraction function; colour has also been hypothesized to function as camouflage, preventing prey avoidance. We tested these two hypotheses in situ for the carnivorous plant Drosera rotundifolia. We conducted three separate studies: (i) prey attraction to artificial traps to isolate the inf...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for Vitex rotundifolia, an endangered species isolated to Lake Biwa, to investigate its genetic diversity and population structure. • METHODS AND RESULTS Ten primer sets were identified in Japanese populations of V. rotundifolia. The number of alleles per locus ranged from one to six and gene diversity per locus ranged from...

Since 1934, the rotundifolia complex of Amblycorypha has consisted of two named species:AmblycoryphaparvipennisStal, occurring fromtheMississippiRiverwestward into theeastern edges of the Great Plains, and Amblycorypha rotundifolia, occurring in most of the eastern United States. The latter entity is here shown to consist of at least three species with distinctive calling songs and different bu...

Muscadinia rotundifolia is a wild grape native to the Southeast U.S. In field trials, as well as in the wild, this species exhibits strong resistance to Pierce’s disease (PD). Incorporating this resistance into Vitis vinifera production systems in California will require identifying prime breeding material and increasing our understanding of the mechanism of resistance. The first objective of t...

After 120 yr of burial in moist, well-aerated sand, 23 seeds of Verbascum blattaria and two seeds of a Verbascum sp. germinated and produced normal plants (50% germination for Verbascum). After a 6-wk cold treatment, a single seed of Malva rotundifolia germinated also, producing a normal plant (2% germination). Plants were grown to maturity in a greenhouse, and flowering was induced by exposure...

A revision of the genus Mitragyna (Rubiaceae) in Thailand is reported. Four species, i.e. M. diversifolia, hirsuta, rotundifolia, and speciosa are described this taxonomic treatment. summary history, detailed morphological descriptions, distributions, ecology, phenology, vernacular names, uses, IUCN conservation status, specimens examined, photographs a key to species proposed. Two names lectot...

Many hepatoprotective herbal preparations have been recommended in alternative system of medicine for the treatment of hepatic disorders. There are few or no systemic studies have been done on protective efficacy of Ziziphus rotundifolia (Rhamnaceae) to treat liver diseases. In this study, hepatoprotective and antioxidant activity of ethanolic extracts was evaluated against CCl4-induced liver d...

Reticulate evolution is considered to be among the main mechanisms of plant evolution, often leading to the establishment of new species. However, complex evolutionary scenarios result in a challenging definition of evolutionary and taxonomic units. In the present study, we aimed to examine the evolutionary origin and revise the species status of Campanula baumgartenii, a rare endemic species f...

Two experiments were conducted to study the effects of increased atmospheric nitrogen deposition and elevated CO2 on investment in carnivory by two sundew species, Drosera rotundifolia and D. intermedia. A field study was conducted with D. rotundifolia at Inverness Mud Lake Bog in Inverness Twp., MI where plants were exposed to simulated future increases in atmospheric nitrogen deposition predi...

INTRODUCTION Phyllagathis rotundifolia (Jack) Bl. (Melastomataceae) is a creeping herb found in Peninsular Malaysia and Sumatra. Traditionally, a decoction of the leaves is used in the treatment of malaria, fever and stomach ache. OBJECTIVE To provide ESI-MS(n) data which are applicable for chemical fingerprinting of P. rotundifolia to obviate laborious isolation and purification steps. MET...
