The stone is obovate, approximately circular in cross section, and bisymmetrical and unilocular (Fig.
7a-h) are distinct from the Cyrtocarpa species described above in having only one developed locule, and are bisymmetrical with a keel in the plane of symmetry (Fig.
The endocarp is oblong-obovoid; asymmetrical, but nearly radially symmetrical to nearly bisymmetrical, with a dorsal keel (Fig.
Bilocular fruits are approximately bisymmetrical (Fig.
The endocarps are subglobose, ellipsoid, to ovoid, laterally compressed and bisymmetrical without an external keel (Fig.
Combining the suture technique and cartilage graft is useful in externally creating a symmetrical nose while internally obtaining a bisymmetrical
cross-sectional nasal valve area .
(26) Symmetry of 1 [degrees] valvular plicae, two states: radial (0), bisymmetrical (1).
(27) Symmetry of armarium, three states: radial (0), bisymmetrical (1), no teeth (2).
1/10 the achene's length, which does not permit a sectional assignment, yet the many-nerved utricle, the bisymmetrical
achene, longer than wide, and the thin style all suggest that possible affinities could be sections Paludosae and Vesicariae.
The fruit is a 2-winged, bilocular bisymmetrical schizocarp formed from a superior ovary.
Among the oldest fin-winged fruits are the bisymmetrical fruits of Gurvanella Krassilov from the early Cretaceous of western Mongolia (Krassilov, 1982) and northeastern China (Sun et al., 2001).
