4' | Domatia two to many sacs to pockets |
5 | Petals 1.8-3.8 mm long; scales with at most a hardly broadened apex (Fig. 36a); crest always present (Fig. 36i-k). Disc interrupted (often almost uninterrupted; Fig. 35). Fruit lobes longer than high and usually sparsely sericeous or lobes about as long as high and glabrous |
5' | Petals 0.5-4 mm long; scales with a (very) much broadened apex (Fig. 36a); crest usually absent (Fig. 36h). Disc uninterrupted (sometimes with a small slit; Fig. 35a,b). Fruit lobes usually longer than high, glabrous |
6 | Leaves 1-6-jugate. Leaflets ovate (to elliptic), asymmetrical; apex usually gradual ly acuminate to caudate, very apex acute to usually mucronulate |
6' | Leaves 1-4-jugate. Leaflets elliptic, usually symmetrical; apex abruptly (acuminate to) cuspidate, very apex usually obtuse (to acute), not mucronulate |
