Figures & Tables

Figure 1:

The general habit of species from Montenegro: A – Chara corfuensis having a spiny outline because of long pointed bract-cells, spine-cells, and stipulodes, B – “Mediterranean Chara” having a less spiny outline, C – male plants of Chara galioides, D – female plants of Chara galioides. Arrowheads indicate female plants, subtle and less conspicuous in comparison to rough male plants bearing large orange antheridia. Photographs by R. E. Romanov.Slika 1: Splošna podoba vrst v Črni gori: A – Chara corfuensis ima trnast obris zaradi dolgih špičastih braktejnih celic, trnskih celic in paprilističev, B – “Sredozemska Chara” ima manj trnast habitus, C – moške rastline vrste Chara galioides, D – ženske rastline vrste Chara galioides. Puščice kažejo manj opazne ženske rastline, saj imajo moške rastline velike oranžne anteridije. Fotografije R. E. Romanov.

Figure 2:

Distribution of charophyte species in Southeast Europe and Cyprus based on available data according to time intervals in the monograph “Charophytes of Europe” (Schubert et al., 2024; see references in the text). A – Chara corfuensis, B – Chara galioides, C – Chara squamosa, D – the taxon of uncertain affiliation “Mediterranean Chara”, E – Tolypella hispanica, F – Sphaerochara intricata, G – Tolypella nidifica. Black dots are records from 1980 on, red dots from 1950 to 1979, and yellow dots before 1950.Slika 2: Razširjenost parožic v jugovzhodni Evropi in na Cipru, prikazana na osnovi podatkov iz monografije “Charophytes of Europe” (Schubert et al., 2024; glej reference v tekstu) v časovnih intervalih. A – Chara corfuensis, B – Chara galioides, C – Chara squamosa, D – takson z nejasno pripadnostjo “Sredozemska Chara”, E – Tolypella hispanica, F – Sphaerochara intricata, G – Tolypella nidifica. Črne točke so podatki od leta 1980 naprej, rdeče točke med letoma 1950 in 1979 in rumene točke pred letom 1950.

Figure 3:

Key traits and the general habit of species from Cyprus and Montenegro. A – Chara squamosa from Cyprus: diplostichous tylacanthous stem cortex with short solitary spine cells, ecorticate branchlets (arrowhead), B – upper part of Sphaerochara intricata, arrowheads indicate typical forked sterile branchlets, C – general habit of Tolypella nidifica, D – general habit of male plants of Tolypella hispanica with large orange antheridia. Photographs: A – F. Bednár, B–D – R. E. Romanov.Slika 3: Ključni znaki in splošen habitus vrst s Cipra in Črne gore. A – Chara squamosa s Cipra: dvoslojna grbančasta skorja stebla s kratkimi, posamičnimi trnskimi celicami, vejice brez skorje (puščica), B – zgornji del vrste Sphaerochara intricata, puščice kažejo značilne viličaste sterilne vejice, C – splošen habitus vrste Tolypella nidifica, D – habitus moške rastline vrste Tolypella hispanica z velikimi oranžnimi anteridiji. Fotografije: A – F. Bednár, B–D – R. E. Romanov.
