BACKGROUND Vanda tessellata (Orchidaceae) has been used in different sorts of ailments such as inflammations, rheumatism, dysentery, bronchitis, dyspepsia and fever in folk medicine. In this study we evaluated the antinociceptive and cytotoxic effect of methanol and aqueous extracts of V. tessellata leaf. METHODS Oral administration of V. tessellata aqueous (VTA) and methanol (VTM) leaf extra...

There are approximately 30,000 species in the family Orchidaceae, with some growing terrestrially and others as epiphytes. Though pollination biology of many these is not well known, there has been a diversity taxa recorded orchid pollinators. Insects, birds, even record mammal have documented successful pollinators, while orchids able to reproduce without use pollen vector. The goal this revie...

Low fruit set values in most orchids (especially epiphytic and tropical species) are normally thought to be the consequence of pollination constraints and limited resources. In particular, pollination constraints are modulated by pollinator visitation rates, pollinator visitation behaviour (promoting crossing or selfing), the type and number of pollinia deposited on stigmas (in the case of orch...

Understanding mating patterns and gene movement in plant populations occupying highly disturbed landscapes is essential for insights into their long-term survival. We used allozyme genetic markers to examine mating patterns and to directly measure pollen flow in the Central American epiphytic orchid, Laelia rubescens. Study populations were located in disturbed, seasonally dry tropical forest i...

The present studies report in vitro propagation of a rare and medicinally important orchid Vanda testacea through foliar explants. Explants were cultured on Mitra et al. (M) medium and its combinations with cytokinins (BAP, Kn 1 mgl each) and auxin (NAA 1 mgl) individually and in combination for initiation of regeneration response, proliferation of regenerants and subsequent development of plan...

Epiphytic plants occupy three-dimensional space, which allows more individuals to be closely clustered spatially than is possible for populations occupying two dimensions. The unique characteristics of epiphytes can act in concert to influence the fine-scale genetic structure of their populations which can, in turn, influence mating patterns and other population phenomena. Three large populatio...

Approximately 10% of vascular plants are epiphytes and, even though this has long been ignored in past research, able to interact with a variety fungi, including mycorrhizal taxa. However, the structure fungal communities on bark, as well their relationship epiphytic plants, is largely unknown. To fill gap, we conducted environmental metabarcoding ITS-2 region understand spatial bark tropical t...
