Monographs Details: Orectanthe
Authority: Carlquist, Sherwin. 1960. Anatomy of Guayana Xyridaceae: Abutboda, Orectanthe and Achtyplola. Mem. New York Bot. Gard. 10: 63-117.
Discussion:Leaves of Orectanthe are basically not unlike those of the species of Abolboda
just described, but differ from them in having a broad, flat shape, and an
abaxial hypodermis (in some places, at least) as well as an adaxial one. The
chlorenchyma cells are elongate in longitudinal section, and have symmetrically
placed short arms (fig. 43). They correspond to the cells shown for Xyris lanata
by Solereder and Meyer (1929, fig. lib).
