- Diagnosis
- Slender shoots usually with trilobed leaves, “birdfoot-imprint”-like in shape, in opposite-decussate phyllotaxis. Basal part of the “birdfoot-imprint”-leaf needle-like, oblong in shape, oval in crosssection, not or slightly contracting near the base, base decurrent, upper leaf part splits off symmetrically into three more or less equal parts. Individual parts needle-like, oblong to lanceolate in shape, oval in cross-section, apex acute- to rounded–obtuse. Middle part slightly longer than the two laterals. All leaf parts entire margined, aligned in a plane. Simple leaves mostly at young lateral shoots, attached helically. Simple leaves lanceolate to oblanceolate or obovate in shape, entire margined, apex obtuse to obtuse–rounded, not or slightly contracting near the base, base decurrent. Simple and divided leaves diverge from the
axis with angles varying from 45° to 90°, spreading and recurving. Adaxial leaf epidermis and epidermis of the axis with longitudinal files of rectangular or isodiametric epidermal cells and stomata. Stomata mostly anomocytic,
not sunken, arranged in simple longitudinal files, orientated transversally relative to the long axes of the leaves and shoots. Fertile structure probably terminal, consisting of at least three capsule-like almost circular organs with radially arranged ribs.
