By the end of this session you should be able to:
Define Flora as a biological term.
Differentiate between Flora and Fauna.
Categorize the floras.
Divide the Earth’s surface phytogeographically.
Classify the vegetation of the earth.
The term is often used to refer to the indigenous plant exist in a restricted geographical region.
Flora can also, referring to groups of plant specific a time period.
The flora of any given region was usually explained in biological terms to include:
• The genus and species of plant,
• Their preferred growing or breeding habits,
• Their connection to one another in the environment.
Flora: All the plants that live in a particular area, time, period, or environment.
ategories of Floras
Local flora Covers a limited geographic area
eg. Flora of Al
Regional flora
Includes a larger geographical area
eg. Flora of Saudi Arabia
Continental flora
Covers the entire continent
eg. Flora of Europe
Phytogeographic distribution
Vegetational Zones
Altitudinal Belts
Floristic Regions
The usage of the "Scientific Names
All languages have common or vernacular names for almost all the important plants of the countries concerned, but the vernacular names of a given plant naturally differ in various languages. This had been a problem for the botanists and for the laymen in general in the absence of a common basis for communication.
In 1753, Linnaeus devised a new system, the "Binomial Nomenclature", which became universally accepted by botanists up to the present day.
An International Botanical Congress establish a 'Code' for botanical nomenclature (International code of botanical nomenclature ICBN )
Each organism should have two epithets; the first is the generic name written in capital letter and the second is the specific epithet the two written in italics or underlined followed by author name in abbreviated form e.g Hordeum vulgare L.
Latin origin is used because it is dead language and can not be changed.
The scientific names are used because they are fixed allover the world and do not changed in diffrent countries.
The International Code of Botanical Nomenclature gives broad outline for the use of the Code including typification, author citation, effective and valid publication etc. The first part or the Code deals with the ranks of taxa in plant classification.
Topography of Saudi Arabia
Saudi Arabia can be divided into 2 zones
The rain fed highlands of the western and southwestern regions (Sarawat Mountains)
The vast arid and extra arid lands of the interior (Najd)
The Kingdom of Saudi Arabia is a country situated in Southwest Asia, the largest country of Arabia, bordering the Arabian Gulf and the Red Sea, north of Yemen. Its extensive coastlines on the Arabian Gulf and Red Sea provide great leverage on shipping (especially crude oil). The kingdom occupies 80% of the Arabian Peninsula. Most of the country's boundaries with the United Arab Emirates (UAE), Oman, and the Republic of Yemen (formerly two separate countries: the Yemen Arab Republic or North Yemen.
