[Family identification key]
1. Petiole (9-)15-40(-50) mm long (shorter on immature plants); leaf blade mostly 7-20 cm long, the margin often undulate; corolla lobes light yellow, lacking lateral segments; mature fruit 10-30 mm long, yellow to orange; seeds 15-20 mm long
1. Petiole 1-11(-14) mm long; leaf blade mostly 0.5-13 cm long, the margin usually plane; corolla lobes mostly white, with 2 lateral segments; mature fruit purple, 3-13 mm long; seeds 3-12 mm long

2. Mature stems lacking thorns and short shoots; leaf blades acute-acuminate towards the apex; inflorescence nodes often crowded with the inflorescences touching or overlapping or nearly so; ovary glabrous
2. Mature stems with thorns and/or short shoots, the short shoots sometimes with pseudowhorled leaves; leaf blades rounded to rounded-acute at the apex (or often acute-acuminate in S. lycioides); inflorescence nodes usually well-spaced with the inflorescences not touching or occasionally somewhat overlapping; ovary pubescent

3. Stem and leaves glaucous; leaf blade midvein often indistinct near the tip and branching or sinuous, reticulate venation sometimes obscure, the upper surface often with fine pellucid spicules
3. Stem and leaves not glaucous; leaf blade midvein mostly straight and distinct to the tip, reticulate venation generally apparent (unless obscured by pubescence), the upper surface without spicules
4
4. Leaf blade underside lustrous with dense pubescence, the green color of the blade surface not apparent
5
4. Leaf blade underside generally not lustrous, glabrous to moderately pubescent, the green color of the blade surface generally apparent
6
5. Young stems glabrate, the stem bark green to cream-white becoming light gray; mature leaf blade underside with appressed silvery white trichomes; pedicels 4-5 mm long
5. Young stems densely pubescent, the stem bark dark brown, red-brown, to purple-gray; mature leaf blade underside with red-brown trichomes (sometimes silvery white and only slightly tawny on young leaves), some villous or ascending; pedicels 6-12 mm long
6. Leaf blades 1-3(-5) cm long
7
6. Leaf blades (3-)5-12 cm long
