Voorbeelden van capitulum

• The morphology of the capitula suggests they are not well adapted for pollination by other nocturnal vectors such as bats or moths.

• One often finds the hymn carefully rubricated, and intended to record the traditional local liturgies, appearing before rather than after the capitulum.

• On the male trees inflorescences are often in fascicles, and with each inflorescence a whorl of bracts surrounds a capitulum of apetalous male flowers.

• The capitula were harvested at weekly intervals during the seed formation stage.

• The bees were in constant motion while on the capitula and did not stop to probe the flowers.

• They typically visited a capitulum for about 4 to 5 s (range 2 to 16 s).

• Shortly after the secretion was noticed the skin began to turn white near the capitulum.

• In the chiropterophilous species the capitula are much larger and typically borne on long, pendent peduncles arranged in little-branched inflorescences.

• The tree had up to about 50 capitula at anthesis on the nights when observations were made and it was reaching the end of its flowering period.

• Musaeus' responsoria may have been refrains designed to answer the verses chosen as 'psalmorum capitula'.

• They hovered briefly about 2 cm from a capitulum, then landed and immediately started moving quickly through the projecting anthers using their fore and mid legs.

• The capitula open acropetally along each inflorescence axis so that usually there is no more than a single capitulum at anthesis per inflorescence at any time.

• For assisted pollination, male inflorescences were collected and pollen was applied to the stigmas of female flowers by rubbing the male capitula directly against the female flowers.

• The capitulum is protected by eight large, sheathing scales and a ring of about twenty tiny scales surround the joint of capitulum and peduncle.

• The outside of the capitulum bears five strengthening calcareous plates corresponding with the plates that protect an acorn barnacle.
