Five species of Poaceae were collected: Briza minor L., Briza
maxima L., Setaria viridis (L.) P.B., Setaria verticillata (L.)
P.B., and Eleusine indica Gaertn., Fruct. Sem. Pl. which
recorded for the first time in the Flora of Syria. Peels from
a
daxial and abaxial leaf surfaces were prepared and stained
with the safranin . The results showed a clearly differences in
these sides: existence or absence of the epidermal elements,
their shapes and their measurements among the species from
one side, and between adaxial and abaxial leaf surface for the
same one from the other side.
A morphological , anatomical and chemical study was carried out on Salvia viridis
L. (Lamiaceae) . The results showed presence of two types of trichomes :
- Glandular hairs with four or eight celled globular heads or with oval heads .
- Eglandular
hairs which are unicellular or multicellular , in addition to presence of
candle shaped eglandular hairs .
The palynological study revealed that the pollen grains were prolate and they had six
germination lines , exine appeared reticulate .
The extraction of volatile oils have been done by dry evaporation using GC/MS
technique , chromatographic analysis of these extracts have showed the presence of
complex of carboxylic acids , hydrocarbons , terpenes , esters and aldehydes .
