In a large numberof tropical and some subtropical Loranthaceae, however, secondary roots are formed from the base of the plant or from branches.

Ethnobotanical studies focus on ethnic knowledge of Adivasi people and development of data bases on ethnic knowledge but also focuses on preservation and regeneration of traditional beliefs and maintenance of traditional knowledge. Objective: The aim of present study is to highlight the traditional actions of herbal plants used by inborn Yanadi community of Seshachalam Biosphere Reserve, Eastern Ghats of Andhra Pradesh, India. Methods: The ethnobotanical field survey was conducted according to the methods adopted by some au- thors. In-depth interviews, interactions were conducted with tribal physicians of Yanadi, Nakkala and Irula as well as other tribes practicing and experiencing the use of plant-based medicine. A normal inquiry form was used to gather the appropriate data on herbal plants and their usage of inborn people’s lifestyle.

  • Taxonomy and Conservation Status of Pteridophyte Flora of Sri Lanka R.H.G
    Taxonomy and Conservation Status of Pteridophyte Flora of Sri Lanka R.H.G. Ranil and D.K.N.G. Pushpakumara University of Peradeniya Introduction The recorded history of exploration of pteridophytes in Sri Lanka dates back to 1672-1675 when Poul Hermann had collected a few fern specimens which were first described by Linneus (1747) in Flora Zeylanica. The majority of Sri Lankan pteridophytes have been collected in the 19th century during the British period and some of them have been published as catalogues and checklists. However, only Beddome (1863-1883) and Sledge (1950-1954) had conducted systematic studies and contributed significantly to today’s knowledge on taxonomy and diversity of Sri Lankan pteridophytes (Beddome, 1883; Sledge, 1982). Thereafter, Manton (1953) and Manton and Sledge (1954) reported chromosome numbers and some taxonomic issues of selected Sri Lankan Pteridophytes. Recently, Shaffer-Fehre (2006) has edited the volume 15 of the revised handbook to the flora of Ceylon on pteridophyta (Fern and FernAllies). The local involvement of pteridological studies began with Abeywickrama (1956; 1964; 1978), Abeywickrama and Dassanayake (1956); and Abeywickrama and De Fonseka, (1975) with the preparations of checklists of pteridophytes and description of some fern families. Dassanayake (1964), Jayasekara (1996), Jayasekara et al., (1996), Dhanasekera (undated), Fenando (2002), Herat and Rathnayake (2004) and Ranil et al., (2004; 2005; 2006) have also contributed to the present knowledge on Pteridophytes in Sri Lanka. However, only recently, Ranil and co workers initiated a detailed study on biology, ecology and variation of tree ferns (Cyatheaceae) in Kanneliya and Sinharaja MAB reserves combining field and laboratory studies and also taxonomic studies on island-wide Sri Lankan fern flora.

These species belong to 8 species (4.9%) of Ferns, 95 species (58.3%) of Eudicots, 2 species (1.2%) of Magnoliids and 58 species (35.6%) of Monocots. They are composed of 55 species of aquatic plants and 108 species of terrestrial plants. The aquatic plants could be divided into 38 species of annual plants and 17 species of perennial plants. The terrestrial plants could be divided into 25 species of annual plants and 83 species of terrestrial plants.

Free radical scavenging activities were evaluated through 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)di-ammonium salt radical scavenging assay, phosphomolybdate radical scavenging assay, hydrogen peroxide assay and reducing power assay using ascorbic acid as the standard. Well diffusion method was adopted for antibacterial activity evaluation of the aqueous extract of fruits and stem against Staphylococcus aureus, Bacillus stereothermophillus, Pseudomonas aeruginosa, Vibrio cholera, Escherichia coli and Acinetobacter baumanii. Phytochemical screening showed presence of tannins, saponins, steroids and terpenoids in the aqueous extracts of both stem and fruits, while glycosides, flavonoids, carbohydrates and reducing sugars were found in the aqueous extract of fruit only.

Field expedition and specimen collection was done and deposited at the herbarium of the Faculty of Agricultural Technology. 400 plant species from 271 genera 98 families were identified. Three species were pteridophytes, one species was gymnosperm, and 396 species were angiosperms. Flowering plants were categorized as Magnoliids 7 species in 7 genera 3 families, Monocots 106 species in 58 genera 22 families and Eudicots 283 species in 201 genera 69 families. Fabaceae has the greatest number of species among those flowering plant families. Keywords: Biodiversity, Conservation, Sa Kaeo, Species, Dipterocarp forest Introduction Deciduous dipterocarp forest or dried dipterocarp forest covered 80 percent of the forest area in northeastern Thailand spreads to central and eastern Thailand including Sa Kaeo province in which the elevation is lower than 1,000 meters above sea level, dry and shallow sandy soil. Plant species which are common in this kind of forest, are e.g. Buchanania lanzan, Dipterocarpus intricatus, D. tuberculatus, Shorea obtusa, S. siamensis, Terminalia alata, Gardenia saxatilis and Vietnamosasa pusilla [1]. More than 80 percent of the area of Burapha University, Sa Kaeo campus was still covered by the deciduous dipterocarp forest called ‘Khok Pa Pek’. This 2-square-kilometers forest locates at 13°44' N latitude and 102°17' E longitude in Watana Nakorn district, Sa Kaeo province.

  • The Origin and Identity of the Calyculus in Loranthaceae: Inferred from the Floral Organogenesis of Loranthus Tanakae Franch

The origin and identity of the calyculus have been disputed for more than a century. Various hypotheses have been proposed, for example, an outgrowth of the axis, a reduced calyx, and a bracteolar (prophyllar) origin, but controversies remain. To obtain a plausible explanation of the origin of the calyculus, we investigated the flowers of Loranthus tanakae using scanning electron microscopy and light microscopy to observe the entire developmental process of the floral parts. Our results show that bracts are not present in L. tanakae. The calyculus, which lacks serving vascular bundles, initiates as a semicircular primordium and then develops into a circular structure by an adnation at both sides. The flower primordium usually cleaves into six petals from its centre along a whorled pattern in two series with three petals each, before or after the calyculus closed. Isomerous stamen primordia probably follow the same initiation pattern as petals do. Several carpels of different sizes initiate simultaneously as a united primordium. We support the hypotheses that the calyculus is of bract or bracteole origin due to its independent initiation from the inflorescence rachis, its similar morphology and positioning as the bract or bracteole, and that having no developmental relationship with the petals.
