FIGURE 5. Variations of PcTTs in the section Leptopogon. A–B. Diploid species. A. Not ramified PcTT in A. macrothrix (Norrmann 115) and A. ternatus (Norrmann 74); B. PcTT showing a second ramification degree in A. leucostachyus (Norrmann 46) and A. selloanus (Norrmann 229); C–F. Hexaploid species. C. PcTT ramified from axillary buds of bracts and prophylls in A. arenarius (Nagahama & Norrmann 29a); D. PcTT ramified from axillary buds of bracts and prophylls in A. lateralis (Schinini et al. 16842); in this species the PcTT ramified from axillary buds of prophylls develops new PcTTs; E. PcTT showing numerous PcTTs developed from axillary buds of bracts and prophylls in A. glaziovii (Norrmann 217a); F. PcTT showing numerous PcTTs developed from axillary buds of bracts and prophylls in A. bicornis (Norrmann & Quarín 91).
