has a rhizome (approx. 10–25 mm diam), with small trailing branches (which are approx. 2–2.5 cm in diam.) and plenty of fleshy toots. The spreading rhizomes give the appearance of a clump forming plant. It can form dense colonies.
305:
It has a small stem, which reaches a height of between 30–60 cm (0.98–1.97 ft), with a few branches (1 or 2) and is about 3–6 cm in diameter. The stem has 3 leaves along it, which overlap and wrap around the stem.
