Flowers 0.5-1 cm in length, sessile pedicellate
, unisexual or bisexual, corolla 4-6-merous; stamens longer than they are wide, male flowers bearing dimorphic stamens, 3 major and 3 minor alternating with each other, anthers versatile dorsifixed; female flowers with nectar glands encircling the atrophied gynoecium and androecium.
Similarities between flowers of Adenanthemum Conwentz and Itea include that the flowers are hermaphroditic, pedicellate
, have a pentamerous and actinomorphic perianth with distinct whorls of sepals and petals, a valvate corolla, a haplostemonous androecium with antesepalous stamens, dorsifixed anthers with introrse dehiscence, a superior ovary (ovary position is variable in Itea), two fused styles, and a single, capitate stigma (Conwentz, 1886; Kubitzki, 2007a).
Flowers opening during the day, spreading at ca 15[degrees] from the axis at anthesis, 2-4 mm pedicellate
and polystichously arranged; sepals elliptic, acute, 10 mm long, the adaxial pair 2-3 mm connate and carinate, the keels extending into the pedicel; corolla spreading distally; petals 16-18 mm long, white, naked, conglutinated for ca 2/3 of their length.
A rame is defined as an inflorescence branch that bears repeating pairs of sessile and pedicellate
spikelets (Allred, 1982).
Delimited peristome; endoperidial body distinct pedicellate
; endoperidium with crystalline matter (pruinose) 8 7.
Staminate flowers Staminate inflorescence capitate, peduncle to 10 mm long, 1012 flowered, short pedicellate
; stamens exserted, indumentum densely short velutinous.
The fruits are pedicellate
, and the pedicel may disperse with the fruit.
Flowers 23 -28 mm long, opening during the day, 1-2 mm pedicellate
. Sepals asymmetrical, 8-13 mm long, acute with a broad lateral wing, short connate, nerved, green or yellow-green.
