Meiotic Studies in Himalayan Celastraceae and Rhamnaceae T. S. Sareen, P. K. Khosla and P. N. Mehra Department of Botany, Panjab
Cytologia 39: 335-339, 1974 Meiotic Studies in Himalayan Celastraceae and Rhamnaceae T.S. Sareen, P.K. Khosla and P.N. Mehra Departmentof Botany,Panjab University, Chandigarh, India ReceivedNovember 25, 1972 The family Celastraceae embraces 850 species belonging to 55 woody genera with wide distribution except in the arctic. About 70 species and 12 genera are met in India. Two of these, Lophopetalum fimbriatum from Eastern Himalayas and L. wightianumfrom South India, yield commercial timber. Several species of Euonymusare ornamental. Rhamnaceae is a family of 58 genera and 900 species distributed in the tropical and temperate regions. Ten genera with roughly 40 species occur in India. Zizy phus jujuba and Z. xylopyrus yield low grade timber. Jujube is one of the most common wild fruit trees in India. This study was part of the wider project "Cytomorphological Investigations of Himalayan Hardwoods" undertaken by us from 1962-1967. The chromosome counts of newly studied species have been published in IOPB chromosome numbers reports (Mehra and Khosla 1969, Mehra and Sareen 1969). Table 1. Source of the material Material and methods The material for meiotic studies was collected from wild populations in the Himalayas. The flower buds were fixed in Carnoy's fluid. After one or two days anther squashes were prepared in 1.0% aceto-carmine. The photomicro graphs as also the camera lucida drawings are at a uniform magnification of •~1360. The voucher specimens have been kept in the Herbarium of the Botany Department of Panjab University . 336 T. S. Sareen, P. K. Khosla and P. N.

ONG* Department of Life Science, Hallym University, Chuncheon 24252, Korea 1PPCWS Office, Forest Department (MONREC/MoECAF), Ywangan 06041, Shan State, Myanmar (Received 18 August 2018; Revised 19 September 2018; Accepted 22 September 2018) ABSTRACT: Myanmar’s plant diversity is expected to be very high given the wide variety of climates and the diverse vegetation and geographical features of the country. Since the publication of Kress et al.’s plant check- list in 2003, new and unrecorded species have been constantly reported by various botanists, but much of Myan- mar’s flora requires more intensive examinations. We conducted joint floristic surveys of several Ywangan areas, including the Panlaung-Pyadalin Cave Wildlife Sanctuary in southern Shan State of Myanmar. The initial identification of seed plant specimens collected from three short floristic expeditions revealed that 23 species were newly recorded species in Myanmar. More than half of these were found to be geographically notable spe- cies, which are known to be endemic to neighboring countries such as China (4 spp.), Thailand (6 spp.), and India (2 spp.). A considerable number of these unrecorded species are distributed in the limestone areas of neighboring countries, reflecting the geological characteristics of the survey area.

Poyang Lake, located in the middle reaches of Yangtze River (central China), constitutes the largest freshwater lake of the country. It harbours high biodiversity and provides important habitat for local wildlife. A dam that will maintain the water capacity in Poyang Lake is currently being planned. However, the local biodiversity and the likely effects of this dam on the biodiversity (especially on the endemic and rare plants) have not been thoroughly examined.
