- Flowers are generally borne solitarily in leaf axils or in inflorescences subtended by bracts, but some taxa are ebractate.
- What we think are flowers are actually brightly hued leaf bracts.
- Even though a continuum was observed between the ‘true’ leaves and bracts, for simplicity all primordia bearing an axillary flower were considered as a bract.
- In addition to a terminal flower there may be several smaller lateral flowers in the axil of cupular bracts, each surrounded by its own small cupule.
- Grasses and bamboos are known to have large deposits of silica in the tissues of leaf blades and inflorescence bracts.
