- Diagnosis
- Achenes 1.2–1.6×1.0, elliptic to narrowly obovate, narrowly biconvex. Faces
slightly concave; edges thick at the apex. Upper half of the achene rounded, abruptly contracted into the style base. Style base up to 2/5 of the achene length, flattened, regularly truncated in a straight breaking point. Lower half of the achene tapering into a wide base, about 1/3 achene width. Base of the achene bearing a thin callus.Wall surface with isodiametric, polygonal cells,
20–35 μm wide (mean 28 μm on the central part of the achene face), giving to the achene an apparent meshed pattern. Utricle remains thin, probably with 2–4 thin nerves on each face.
