FIGURE 1 in A review of the Euphorbia schinzii-complex (Euphorbiaceae) in southern Africa

FIGURE 1. Tips of branches showing arrangement of tubercles and spine-shields with spines and stipular prickles. A–D, tubercles fused vertically into angles (though fusion of tubercles is the least in D), often with larger stipular prickles (largest in A and B and smallest in D) and spine-shields narrowly elliptic in A and B becoming more narrowly deltate in C and D, E–H, tubercles not fused vertically into angles, with minute stipular prickles and shortly deltate spine-shields, which are especially short in E and G. A, E. schinzii subsp. schinzii, Bruyns 9390 (BOL), ± 8 mm thick. B, E. schinzii subsp. bechuanica, Bruyns 12101 (BOL), ± 10 mm thick. C, E. schinzii subsp. schinzioides, Bruyns 12426 (BOL), ± 8 mm thick. D, E. venteri, Bruyns 12354 (BOL), ± 6 mm thick. E, E. clivicola subsp. clivicola, Bruyns 12115 (BOL), ± 10 mm thick. F, E. clivicola subsp. clivicola, Bruyns 11329 (BOL), ± 6 mm thick. G, E. clivicola subsp. clivicola, Bruyns 13556 (BOL), ± 8 mm thick. H, E. clivicola subsp. calcritica, Bruyns 12045 (BOL), ± 6 mm thick.
