Identification Key
1. Plant dioecious (flowers unisexual); leaf blades (at least some) sagittate or hastate
2
1. Plant monoecious (flowers bisexual and sometimes unisexual); leaf blades not sagittate nor hastate
3
2. Pedicel articulated near base of tepal; inner tepal lacking a wing, as wide as achene
2. Pedicel articulated at middle or below; Inner tepal with a conspicuous wing, much wider than achene
3. Inner tepal margins dentate
4
3. Inner tepal margins entire to crenulate
7
4. Inner tepal scarcely reticulate, the the tubercle (basal medial callosity of inner tepal) smooth and acute at the tip
5
4. Inner tepal alveolate-reticulate, the tubercle (basal medial callosity of inner tepal) verrucose and obtuse at the tip
6
5. Larger leaf blades 20-40 cm long
5. Larger leaf blades 4-7 cm long
6. Leaf blade coriaceous, cuneate at the base
6. Leaf blade chartaceous, subcordate to truncate at the base
7. Plants with long-creeping underground rhizomes and/or stolons, producing ascending or erect axillary shoots; inner tepals 2.5-3.5 mm wide
7. Plants without rhizomes or stolons; inner tepals 3-9 mm wide
8
8. Pedicels 7-17 mm long, 2.5-5 times longer than inner tepals
8. Pedicels 3-5 mm long, 2-2.5 times longer than inner tepals
9
9. Inner tepal 5-10 mm wide, the tubercle 1(-3) per flower and smooth, free margin of tepal often 2 times as wide as tubercle
9. Inner tepal 3-5 mm wide, the tubercle (1-)3 per flower and reticulate-rugose, free margin of tepal subequal to the tubercle in width
10
10. Plants not developing basal rosette of leaves; free margins of inner tepal wider than or at least as wide as tubercle; inflorescence interrupted nearly throughout
