Unusual carpological characters in Marlothiella gummifera (Apiaceae)
AbstractFlowers and fruits of the monotypic Namibian endemic Marlothiella gummifera were examined to explore anatomical variation and to highlight problems associated with the homology of certain character states. Some unusual new features observed in the fruits and ovaries raise questions regarding the homology of fruit heteromorphy, rib oil ducts ...

A new way of dissemination in Anagallis arvensis L. (Primulaceae)
Anagallis arvensis L. fruits are globose pyxides. They contain a unique globose columella with 20-30 seeds on its surface. In ripe, open fruits the ball-shaped columella detaches easily and becomes a unique diaspore, which can roll on the ground.

Carpological features of certain Artemisia species distributed in Ukraine
The achenes’ micromorphological structure of six Artemisia species (A. absinthium, A. annua, A. argyi, A. dracunculus, A. marschalliana, and A. vulgaris) distributed in Ukraine was investigated with the aim to identify taxonomically significant carpological features for the studied species.Fruits were collected from wild plants growing in the ...

Most important carpological anatomical characters in the taxonomy of Apiaceae
Abstract Carpological anatomical characters are important in the taxonomy of Apiaceae. At present, it is necessary to include them in any critical revision of taxa of every rank, to characterize species and genera and to identify groups of related taxa.

ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.
