| Key to the subspecies | |
1 | Red-brown wood zone on inner face of fruit valve beside seed cavity at widest point towards base 1–2.5 mm wide; indumentum on branchlets appressed hairy to tomentose, usually quickly glabrescent, sometimes persisting to flowering. | 2 |
| Red-brown wood zone on inner face of fruit valve beside seed cavity at widest point towards base 3–5 mm wide; indumentum on branchlets tomentose, persistent to well after flowering. Follicle ovoid, 26–36 mm wide. | subsp. platytaenia |
2 | Follicles ovoid to obovoid, 14–19 mm wide; pale wood zone 3.5–6 mm wide, the outer layer mostly 1–2.5 mm wide. | subsp. decurrens |
