- Diagnosis
- Axial shoots with helically arranged fl at linear, falcate or scale-shaped leaves,
varying in shape and size. Ultimate branchlets with linear or linear-lanceolate distichous leaves,
reaching 5—14 mm (usually 6—8 mm) in length. Apex of the linear leaves broadly triangular
with blunt or rounded point. Leaves hypostomatic. Stomatal bands with 3—5 stomata per
width, 1—3 stomata near the apex, stomata no forming the rows. On some leaves stomata
oriented longitudinally or obliquely, on the other irregularly. Subsidiary cells with cuticular
thickenings of the aperture walls, those form a cuticular rim around the stomatal pit.
