Fig. 3.

Illustration of the venation pattern and leaf vein density on cleared leaves of three Salsoleae species of formerly Salsola section Coccosalsola, Salsola masenderanica (A), S. montana (B), S. divaricata (C), and the C₄ Salsoloid-type species Caroxylon orientale (D). Observation of cleared leaves under UV light shows a low branching pattern with few terminal ends and low density of the veins in three species, S. masenderanica (A), S. divaricata (C), and C. orientale (D), and a higher density of branched veins in S. montana (B). Scale bars=200 μm.
