| Corolla lobes a third to half as long as corolla; stamens much exserted; fresh leaves slightly fleshy, some more than 5 mm wide | 2 |
2 | Lateral branches mostly more than 10 mm long, leafy, ending in a spine, leaves mostly obovate; berry more or less globose | Lycium ferocissimum |
| Lateral branches mostly less than 10 mm long, leafless, ending in a spine, or spines absent; leaves mostly ovate; berry more or less ellipsoid Back to 1 | Lycium barbarum |
