Wawae Iole (Lycopodium cernuum). The Hawaiian name for this clubmoss means"rat's foot." Like the moa (Psiloturn sp.), It is a primitive plant which reproduces through spores. The wawae'iole is often used in flower arrangements and lei, though the picking of it in native forests may unintentionally lead to the introduction of weeds. Weed seeds, carried on the soles of shoes or stuck to clothing, can be dispersed through the native forest by gatherers or hikers. It is a good idea to scrub the soles of your shoes and pick any "stickers'' off your clothes before hiking in any relatively untouched area.
