Abstract
1 The taxonomic reviSIOn of some indigenous spec1es of
Chenopodiaceae in Ek’YPt was based on the fresh materials collected by
the author from various phytogeographical territories throughout the
country; as well as the Herbarium specimens deposited in CAI and
CAlM, ( Index Herb abbreviations). It was based mainly on the
morphological characters of the embryo, fruit-perianth, branches,
leaves and seeds.
2 - The revision revealed. the presence of eight species belonging to
five genera. Of these, Halocnemum strobilaceum, Arthrocnemum
macmstachyum, Salicomia fruticosa and Anabasis articulata are very
common; while Salicomia europaea, Noaea mucronata and Anabasis
setifera are common. Salicomia lignosa is rare and confined in its
distribution to the northern parts of the Nile Delta (Borollos and San el
Hagar).
3 - The community and habitat characters for each spec1es were
studied. The associate species were recorded and ranged between 4-30.
4 - Field studies showed that, the investigated species can be grouped
into:
a - Halophytes, which are confined to saline habitats and can be
arranged on the basis of descending order of salinity follows :
Halocnemum strobilaceum, Arthrocnemum macrostachyum,
Salicomia fiuticosa, S.europaea and S./ignosa.
b - Glycophytes, which generally exploit non-saline habitats or
abotmded to deserts and semideserts. Here belong : Noaea mucronata,
Anabasis setifera and A. articulata.
5 - Chemical analysis of the shoots included the determination of ash,
total carbohydrates, total nitorgen and total lipids as well as analysis of
hydrocarbons, sterols and fatty acids in both shoots and seeds of the
studied species.
6 - The ash content attained its highest value in the halophytic
Halocnemum strobilaceum followed by the glycophytic Anabasis
a~ticulata. Elemental analyses of the ash content of the studied species
showed that the highest values of sodium, potassium, calcium and
phosphoms were detected m the halophytic Halocnemum
strobilaceum. A higher accumulation of magnesium was recorded in
the glycophytic Anab,1sis articulata.
7 - The highest values of total carbohydrates content, total nitrogen
content and total lipid content were recorded in halophytic
Halocnemum strobilaceum. The lowest values of total carbohydrates
and total nitrogen were detected in Salicomia lignosa, and that of total
lipids were recorded in Anabasis setikra.
8 - Hydrocarbon and sterol analyses in shoots and seeds showed that
tricosane and octacosane were the most prominent hydrocarbons as
well as cholesterol and campisterol as the major sterols.
9 - Fatty acids analyses of shoots and seeds revealed variations in
number, composition and concentration of each of the individual fatty
acids; with myristic and palmitoleic as the major fatty acids.
Summary & ConclusionI 0 - A suggested key was constmcted for the studied spec1es
depending on the morphological characters, ecological features and the
fatty acdis constituents.
