Merging Fargesia dracocephala into Fargesia decurvata (Bambusoideae, Poaceae): Implications from Morphological and ITS Sequence Analyses
Figure 2
A–C. Close up of upper part of sheathes and lower part of sheath blades in different of a same annual culm in Pop 4.
Bar = 5 mm. A. In lower part, showing blade base decurrent (arrow) and as wide as sheath apex. B. In middle part, showing blade base not decurrent (arrow) and narrower than sheath apex. C. In upper part, showing blade base not decurrent (arrow) and much narrower than sheath apex. D–L. Close up of leaf auricles and oral setae, showing the shape of leaf auricles and position of oral serae. Bar = 1 mm. D–F. From Pop 1. D–E. From an annual culm. D. Long triangular auricle with serae at upper margins and apex. E. Curving long triangular auricle with setae at margins and apex. F. Short sickle-like with setae mostly at one margin and apex from a perennial culm. G–H. From Pop 3. G. Sickle-like auricle with setae mostly at one margin and apex from an annual culm. H. Very narrow sickle-like auricle with setae mostly at one margin and apex from a perennial clam. I–J. Culms from Pop 8. I. Banding auricle with setae at upper margins and apex from an annual culm. J. Short banding auricle with setae at upper margins and apex from a perennial culm. K–L. From Pop 10. K. very small auricle with setae at whole margin from an annual culm. L. Almost without auricle but with setae on upper margin of sheath from a perennial culm. C: culm. CB: culm sheath blade. CS: culm sheath. LA: leaf auricle. LS: leaf sheath. S: oral seta.
