Sapria Himalayana the Indian Cousin of World’S Largest Flower
GENERAL ARTICLE Sapria Himalayana The Indian Cousin of World’s Largest Flower Dipankar Borah and Dipanjan Ghosh Sighting Sapria in the wild is a lifetime experience for a botanist. Because this rare, parasitic flowering plant is one of the lesser known and poorly understood taxa, which is on the brink of extinction. In India, Sapria is only found in the forests of Namdapha National Park in Arunachal Pradesh. In this article, an attempt has been made to document the diversity, distribution, ecology, and conservation need of this valuable plant. Dipankar Borah has just completed his MSc in Botany from Rajiv Gandhi Introduction University, Arunachal Pradesh, and is now pursuing research in the same It was the month of January 2017 when we decided for a field department. He specializes in trip to Namdapha National Park along with some of our plant Plant Taxonomy, though now lover mates of Department of Botany, Rajiv Gandhi University, he focuses on Conservation Arunachal Pradesh. After reaching the National Park, which is Biology, as he feels that taxonomy is nothing without somewhat 113 km away from the nearest town Miao, in Arunachal conservation. Pradesh, the forest officials advised us to trek through the nearest possible spot called Bulbulia, a sulphur spring. After walking for 4 km, we observed some red balls on the ground half covered by litter. Immediately we cleared the litter which unravelled a ball like pinkish-red flower bud. Near to it was a flower in full bloom and two flower buds. Following this, we looked in the 5 m ra- dius area, anticipating a possibility to encounter more but nothing Dipanjan Ghosh teaches Botany at Joteram Vidyapith, was spotted.

Review Biologi Rafflesia: Apa yang sudah kita ketahui dan bagaimana selanjutnya? Siti Nur Hidayati* and Jeffrey L. Walck Department of Biology, Middle Tennessee State University, Murfreesboro, TN 37132, USA *Email: [email protected] Diterima/Received: 29 Desember 2015; Disetujui/Accepted: 8 Juni 2016 Abstrak Telah dilakukan tinjauan literatur untuk meringkas informasi, terutama karya ilmiah yg baru diterbitkan, pada biologi Rafflesia. Sebagian besar publikasi terkini adalah pemberian nama species baru pada Rafflesia. Sejak tahun 2002, sepuluh spesies telah ditemukan di Filipina dibandingkan dengan tiga spesies di Indonesia. Karya terbaru filogenetik juga telah dieksplorasi (misalnya sejarah evolusi genus Rafflesia dan gigantisme, transfer horizontal gen dan hilangnya genom kloroplas) dan anatomi (misalnya endofit, pengembangan bunga); studi terbaru lainnya berfokus pada biokimia. Sayangnya, masih banyak informasi yang belum diketahui misalnya tentang siklus hidup, biologi dan hubungan ekologi pada Rafflesia. Kebanyakan informasi yang tersedia berasal dari hasil pengamatan. Misalnya penurunan populasi telah diketahui secara umum yang kadang kadang dikaitkan dengan kerusakan habitat atau gangguan alam tapi penyebab-penyebab yang lain tidak diketahui dengan pasti. Pertanyaan yang belum terjawab antara lain pada biologi reproduksi, struktur genetik populasi dan keragaman. Dengan adanya perubahan iklim secara global, kita amat membutuhkan studi populasi jangka panjang dalam kaitannya dengan parameter lingkungan untuk membantu konservasi Rafflesia. Keywords: Rafflesia, Indonesia, Biologi, konservation, review Abstract A literature review was conducted to summarize information, particularly recently published, on the biology of Rafflesia.

Apart from the flower shoot and associated bracts, the parasite is a myce- lium-like endophyte living inside their grapevine hosts. This study provides a comprehensive treatment of the endophytic vegetative body for all three genera of Rafflesiaceae (Rafflesia, Rhizanthes and Sapria), and reports on the cytology and development of the endophyte, including its structural connection to the host, shedding light on the poorly understood nature of this symbiosis. † Methods Serial sectioning and staining with non-specific dyes, periodic–Schiff’s reagent and aniline blue were employed in order to characterize the structure of the endophyte across a phylogenetically diverse sampling.

STUDIES in MALESIAN VITACEAE VII. the Genus Tetrastigma in the Malay Peninsula
STUDIES IN MALESIAN VITACEAE VII. The genus Tetrastigma in the Malay Peninsula A. LATlFF Botany Department, Universiti Kebangsaan Malaysia, Bangi, Selangor, Malaysia EFFECTIVE-PUBLICATION DATE: 7TH MAR. 1984 Abstract A revision of the genus Tetrastigma (Miq.) Planch. in the Malay Peninsula is presented. Twelve species are here redescribed and assigned to section Tetrastigma and section Carinata sect. nov. They are: T. pedunculare (Wall. ex Laws.) Planch., T. papillosum (Bl.) Planch., T. pyrijorme Gagnep., T. scortechinii (King) Gagnep., T. dubium (Law.) Planch., T. cruciatum Craib & Gagnep., T. lawsoni (King) Burkill, T. dichotomum (Bl.) Planch., T. lanceolarium (Roxb.) Planch., T. hookeri (Laws.) Planch., T. curtisii (Rid!.) Suesseng., and T. godefroyanum Planch. Six species, namely, T. papillosum, T. pyrijorme, T. cruciatum, T. dichotomum, T. hookeri, and T. godefroyanum, represent new additions to the flora of the Malay Peninsula, and two established species names are reduced, namely, T. kunstleri (King) Craib (to T. lanceolarium) and T. wrayi (King) Craib syn. nov. (to T. dubium). A general discussion on the growth habits and morphology of stem, inflorescence, flowers, fruits and seeds is also given. Introduction The largest genus of the Malayan Vitaceae is Tetrastigma (Miq.) Planch., which comprises 12 species. The genus is characterized by its 4-lobed or 4-cleft stigma in the pistillate flowers. In the other genera, the stigma is subcapitate (as in Ampe/o cissus, Cissus, and Cayratia) or entire (as in Pterisanthes). The value of the stigmatic characteristic of Tetrastigma was first recognised by Miquel (1861) when he included all the then known species of Vitis (sensu /ato) which have a 4-segmented stigma under section Tetrastigma Miq.
