Common name(s): [more details]

English: calliandra, powderpuff, red calliandra

Samoan: kaliana

Habit:  shrub

Description:  "Leafstalks of larger leaves 8-15 cm, their longer interpinnal segments 6-10 (-12) mm; rachis of longer pinnae (4-) 5-8.5 cm; longer leaflets linear acute 4-9 (-10) x 0.65-1.9 mm, either straight or gently incurved.  Inflorescence-axes either glabrous, or puberulent, or pilose, but the peduncles at most thinly so; peduncles (3-) 4-12 (-15) mm; pedicels 2-4.5 mm; perianth commonly glabrous, rarely minropuberulent; calyx 1.6-2.3 x 2.2-3.2 mm, the teeth 0.25-0.6 mm; corolla (6-) 6.5-9.5 (-11.5) mm, the lobes as long as tube or separating to rim of stemonozone; androecium 40-52-merous, usually crimson throughout, occasionally pallid proximally and pink distally.  Pods in profile 8-11 (-12) x 1.1-1.6 cm, commonly glabrous or micropuberulent, less often strigulose or even pilose" (Barneby, 1998; pp. 180-182).

"Slender shrubs, rarely to 10 m tall, nearly glabrous; leaves with 15-20 pairs of pinnae; the leaflets rounded or very obtuse, not curved. Flowers in mimosa-like "powderpuffs", the corolla glabrous or nearly so. Each flower opens for a single night to display showy filaments, which usually are white at the very base and red at the tip (although they may be pink). By the next day, the filaments have wilted, and unfertilized flowers drop. Pods 8-11 cm long, ca 1 cm wide, with 3-15 seeds" (University of Connecticut, Ecology & Evolutionary Biology Conservatory).

Habitat/ecology:  "In brush-woodland, along stony river banks, on roadsides, in wasteland, and in undisturbed open forest, (2-) 50-1400 (-1650) m" (Barneby 1998). "Along riverbanks or disturbed areas from 0-1900 m" (University of Connecticut, Ecology & Evolutionary Biology Conservatory).
