Fruit morphology in Galium section Platygalium (Rubiaceae) and its potential taxonomic significance
Fruit (mericarp) morphology of nine species from section Platygalium of the genus Galium from Russia were examined with light microscope and scanning electron microscope (SEM). Macro- and micromorphological characters, including fruit shape, size, and types of mericarp surface and indumentum are presented. Three types of mericarp surface were observed, glabrous, hairy with either hooked or straight hairs and tuberculate. The ... Read more

ON THE CORRELATION OF POLLEN GRAIN SIZE AND PLOIDY LEVELS OF GENUS GALIUM SECT. PLATYGALIUM
Pollen grain size of some species of Galium section Platygalium (Rubiaceae) have been studied in diploids (2n = 2× = 22, in G. boreale, G. valantioides, G. broterianum), tetraploids (2n = 4× = 44, in G. boreale), hexaploids (2n = 6× = 66, in G. boreale) and in dodecaploid (2n = 12× = 132, in G. rubioides), and many other ...

Two subspecies of Galium setaceum (Rubiaceae) in Egypt
The systematics, distribution and morphology of Galium setaceum (Rubiaceae) in Egypt are described in the article. A full discussion is provided of all morphological characters, systematic treatment and nomenclature based on macro characters, such as habit, distribution, leaf, inflorescence, peduncle, pedicel, flowers, and micro characters of trichomes. G. setaceum subsp. decaisni is identified for the flora of Egypt for the ... Read more

Numerical taxonomy of Galium (Rubiaceae) in Egypt
On the basis of fifty morphological characters, including vegetative parts, flowers, fruits, seeds, pollen grains, and anatomical structure, a systematic study of 13 taxa belonging to genus _Galium_ (Rubiaceae) from Egypt was conducted by means of numerical analysis. Four branches and clusters were distinguished. Representatives of these groups were clustered together according to characters with high factor loading in the ... Read more

Fruit and seed morphology in Galium L. (Rubiaceae) and its importance for taxonomic identification
Fruit (mericarp) and seed morphology of 11 species and two subspecies of _Galium_ were examined with light microscope and scanning electron microscope. Macro- and micromorphological characters, including fruit and seed shape, colour, size, surface, epidermal cell shape, anticlinal boundaries, outer periclinal cell wall and relief of outer cell walls, are presented. Four different types of mericarp surface are described. Three ... Read more
