Rhynchospora
Achene 0.7-1.8 mm long, 0.7-1.5 mm wide, the summit without a textured rim surrounding the base of the tubercle (if the base of the tubercle is rim-like, then it is distinguished from the summit of the achene by a constriction or articulation).

Aristida
Awn column (the connivent awns twisted together) or lemma beak (slender, narrowed, and twisted portion of lemma body below the awns) 7-30 mm long; lemma body (including the beak, if present) separated from the awns (or awn column) by an articulation zone, the awns (or awn column) disarticulating at maturity from the lemma.

Hypericum
Leaves with an articulation at the very base, this appearing as a narrow line, groove, or abrupt change of color and texture which extends (usually laterally) across the base of the petiole or leaf blade (if sessile); plants shrubs; [section Myriandra].
