“…Given the highly diverse nature of plant characters, it is often necessary to consider several characteristics for a key to function as a reliable identification tool. These characteristics include simple, easily observable, stable, and reliable (El-Gazzar et al, 2015. Based on the expert assessment, the number of key characters for M. crenata is adequate, consisting of nine characters as a combination of morphology, anatomy, qualitative, and quantitative characters.…”

An identification key is one of the tools used to determine the identity of a plant specimen. This research aims to design an identification key for M. crenata and analyze its potential as an identification tool. The research uses an observational descriptive method. The identification keys were designed for populations growing in aquatic floating, emergent, and terrestrial habitats. The key types designed are (1) short parallel, (2) long parallel, (3) numerical, (4) circular diagram, and (5) columnar diagram. The key characters are qualitative and quantitative, consisting of seven morphological and two anatomical characters. The potential of the identification keys was evaluated based on expert judgment regarding the quality and relevance of the keys as identification tools, accuracy, time, and assessment of student satisfaction. The data were analyzed quantitatively and descriptively. The reliability of expert judgment data was determined based on the percentage of agreement and Cronbach α, while the Kruskal Wallis and Mann-Whitney tests were used to analyze student assessment data and to determine the mean as well as SD of identification time. Student responses were processed in the form of percentages. The results of the expert assessment show that five key types have potential as a tool of identifying ferns diversity. Based on the effectiveness of key use and student assessment, numerical keys are the type that has the least potential, while short parallel keys have the best potential as a tool of identification. However, the five key types that have been developed can be used in learning to train students' identification skills.

“…The DELTA package was applied successfully to the flora of several countries and to the genera and species of numerous families. For example, applications of this method to the flora of Egypt include studies on the Mimosoideae and Caesalpinioideae of the Leguminosae (El-Gazzar et al, 2008a), the Chenopodiaceae (El-Gazzar et al, 2008b), the Plantaginaceae (El-Gazzar et al, 2009a), the Solanaceae (El-Gazzar et al, 2009b), the Leguminosae-Papilionoideae (El-Gazzar et al, 2012), the Boraginaceae (El-Gazzar et al, 2015a), the Acanthaceae (El-Gazzar et al, 2015b), the Lamiaceae (El-Gazzar et al, 2019b), and the Asteraceae (El-Gazzar et al, 2019a. A list of the numerous applications of the DELTA suite of programs to various groups of plants, animals and micro-organisms in other parts of the world is given by Dallwitz (1993 onwards).…”

Computer-Generated Keys and Descriptions of the Flora of Saudi Arabia: A Pilot Study on Some Grasses from Jazan

T HIS IS THE FIRST use of computer programs to construct keys and descriptions of plants in the flora of Saudi Arabia or any other country in the Arabian Peninsula. The program suit DELTA was used to generate a conventional key to 55 species of Poaceae collected from Jazan region, Saudi Arabia, on the basis of a dataset comprising 50 easily observable morphological characters. Together with the key, the outcome of the computer run includes descriptions for individual species in natural language based on the entirety of the 50 characters recorded for every species to be used in the confirmation of its identity. The computer-generated key avoids the numerous inconsistencies encountered frequently in its traditional counterparts, and can easily be regenerated to accommodate additional taxa and/or characters. This study was undertaken as a model for other studies aiming at improving floristic studies in Saudi Arabia and the procedure adopted here is equally applicable to all other groups of wild and cultivated plants in the the country.

“…In Egypt, the genus Dicliptera was represented by only one species D. paniculata (Peristrophe paniculata), a rare species known only from Gebel Elba and Red Sea Coast of Egypt (Täckholm, 1974;El Hadidi & Fayed, 1994/ 95;Boulos, 2002Boulos, , 2009Shamso, 2010, 2013and El-Gazzar et al, 2015. As part of the revisionary study of the genus Dicliptera in Egypt, Shamso (2010) recorded Dicliptera paniculata with a wide range of variation in many morphological characters.…”

D ICLIPTERA aegyptiaca, a new species from Red Sea Coast, Egypt, is described and illustrated. Diagnostic and morphological characters that distinguish it from its allied species D. paniculata and an identification key for the two species are provided. The new species differs from D. paniculata by having an unbranched stem, a congested inflorescence with dwarf axes 1.5-5mm long; subsessile cymules with peduncles 0.5-1mm long. rbcl-DNA barcoding is presented for this new taxon for the first time. Phylogentic tree revealed barcode clusters for the two Dicliptera species and recognized significant interspecific variation between them. D. aegyptiaca clearly formed one clade strongly supported with a bootstrap value of 100%. Based on characters of morphology, pollen and seeds, the new species was recognized as belonging to the genus Dicliptera. On the other hand, DNA barcoding reflected clustering of all Dicliptera spp. in a large clade while D. aegyptiaca formed a non sister clade showing the utility of DNA barcoding for species identification rather than taxonomy.
