Distribution map of Chara connivens populations on the Canary Islands (Spain). Red circle: new stand; yellow circles: previously known stands. Stands: 1 – El Golfo, 2 – Las Cuevitas, 3 – Añocheza, 4 – Adeje, 5 –El Barranco del Infierno, 6 – Costa del Silencio, 7 – Armeñime, and 8 –El Barranco de las Peñitas.

Male specimen of Chara connivens from the El Barranco de las Peñitas canyon (Fuerteventura Island). A – slender thalli; B – the upper part of the thallus (in the middle); C – an incurved branchlet (black arrow) and an ecorticate terminal segment of the branchlet (white arrow); D – slender thalli with visible male gametangia (antheridia); E – a node with a double whorl of rudimentary stipulodes (white arrow) and the main axis (stem) with triplostichous isostichous cortex (black arrow); and F – a single, typically orange-reddish male gametangium (antheridium).
