Abstract

This work is devoted for the floral richness and seasonality evaluation of the plant communities of the Tessala Mountains in Western Algeria. The floristic inventory of the 30 surveys carried out on 10 selected stations has resulted in 152 species under 125 genera and 48 families. Seasonal floral richness is concentrated in both spring and summer seasons, while the monthly richness is significant between Marchto August. Vegetations formations are represented physiognomically by four strata, taken into consideration in descending order of importance: Herbaceous (68%), shrubby (12%), arbustive (11%), and arborescent (10%). The overall and seasonal distributions of biological types almost follow the diagrams: Therophytes (The)> Hemicryptophytes (Hem)> Phanerophytes(Pha) > Chamephytes (Cha)> Geophytes (Geo). During the two season: the winter and the spring, the annual herbaceous dominate the bio-morphological spectrum with perennial herbs. During the summer and autumn, perennial herbaceous plants dominate the bio-morphological spectrum. The families that are mostexisting overall and during the four seasons are Asteraceae, Poaceae, Lamiaceae and Fabaceae. Bangladesh J. Plant Taxon. 30(2): 233-248, 2023 (December)

阿尔及利亚西部泰萨拉山区花卉的丰富性和植物多样性的季节性

这项研究致力于对阿尔及利亚西部泰萨拉山区植物群落的花卉丰富度和季节性进行评估。在 10 个选定站点进行的 30 次调查中，共收集到 125 属、48 科、152 种植物。季节性花卉丰富度主要集中在春季和夏季，而月度丰富度主要集中在 3 月至 8 月。从生理学角度看，植被有四个层次，重要性依次递减：草本植物（68%）、灌木（12%）、乔木（11%）和灌木（10%）。生物类型的总体分布和季节分布几乎如图所示：叶绿体（Therophytes）>半隐叶植物（Hem）>显叶植物（Phanerophytes）>变叶植物（Chamephytes）>地被植物（Geophytes）。在冬季和春季这两个季节，一年生草本植物与多年生草本植物在生物形态谱中占主导地位。在夏季和秋季，多年生草本植物在生物形态谱中占主导地位。四季中存在最多的科是菊科、禾本科、芸香科和豆科。孟加拉国植物分类学杂志》。30(2):233-248，2023 年（12 月）

期刊介绍： Bangladesh is a humid, subtropical country favouring luxuriant growth of microorganisms, fungi and plants from algae to angiosperms with rich diversity. She has the largest mangrove forest of the world in addition to diverse hilly and wetland habitats. More than a century back, foreign explorers endeavoured several floral expeditions, but little was done for non-vasculars and pteridophytes. In recent times, Bangladesh National Herbarium has been carrying out taxonomic research in Bangladesh along with few other national institutes (e.g. Department of Botany of public universities and Bangladesh Forest Research Institute).
