Abstract Species of Acanthaceae are predominantly associated with conserved forest environments such as Iguaçu National Park (PARNA Iguaçu), which is composed Semideciduous Seasonal Forest and Araucaria forest. The aim this work was to perform a floristic study PARNA Iguaçu, botanical illustrations, an identification key descriptions the species. Collections were carried out monthly from August...

The present study was mainly conducted to investigate the survey of arbuscular mycorrhizal biodiversity in rhizosphere soil and root colonization of medicinal plant species in Sirumalai hills, Eastern Ghats of Dindugul district, Tamilnadu. Soil samples were collected during the month of September 2014 from the surface to 30 cm depth and pH was measured. Rhizosphere soil root of 20 plant species...

Nilgirianthus heyneanus is widely used in South India in place of Sahachara (Barleria prionitis L) and is considered as an important Vatahara drug. Detailed pharmacognosy of the root of N. heyneanus commonly known as Karim Kurinji (Malayalam) in Kerala has been carried out. Some of the diagnostic features of the drug are pigmented cystoliths in the cortex and pith region; yellow colour cell con...

This study evaluated whether the herb Ruellia nudiflora is locally adapted to a specialist insect seed predator (SP) and insect folivores, and if plant local adaptation (LA) to the former is more likely. A reciprocal transplant experiment was conducted using three sites in Yucatan (Mexico) (n = 864 plants). A third of the plants of each origin were placed at each site, and we recorded the follo...

Pollination systems frequently reflect adaptations to particular groups of pollinators. Such systems are indicative of evolutionary specialization and have been important in angiosperm diversification. We studied the evolution of pollination systems in the large genus Ruellia. Phylogenetic analyses, morphological ordinations, ancestral state reconstructions, and a character mapping simulation w...

Chromosome numbers of one species Eranthemum (E. macrophyllum Wall. ex Nees) and five Strobilanthes [S. affinis (Griff.) Terao J. R. I. Wood et Benett., S. biocullata Y. F. Deng & Wood, dimorphotricha Hance, heteroclita D. Fang H. Lo pseudocollina K. He Qin] in the family Acanthaceae from China have been reported for first time. The chromosome were determined as 2n=4x=44 E. macrophyllum, 2n=2x=...

Andrographis paniculata (Burm. F) Nees, generally known as "king of bitters," is an herbaceous plant in the family Acanthaceae. In China, India, Thailand, and Malaysia, this plant has been widely used for treating sore throat, flu, and upper respiratory tract infections. Andrographolide, a major bioactive chemical constituent of the plant, has shown anticancer potential in various investigation...

This study aimed to characterize the structure of the herb stratum in relation to light availability in the Submontane Atlantic Rain Forest at the Carlos Botelho State Park, SP, Brazil. Fortyone 10 x10 m plots were established under the closed canopy (18 plots), small and medium canopy gaps (11) and large canopy gaps dominated by Guadua tagoara (Ness) Kunth (12). Inside each plot, the line inte...
