In inflorescences these two different growth patterns are called indeterminate and determinate respectively, and indicate whether a terminal flower is formed and where flowering starts within the inflorescence. Indeterminate inflorescence: Monopodial (racemose) growth. The terminal bud keeps growing and forming lateral flowers.

3. Sterile flower s, e.g. in Muscari and Leopoldia, at the apex of some inflorescences. 4. A tuft of hairs at the base of some flowers, e.g. in Pfaffia gnaphalioides. 5. A tuft of hairs at the apex or base of some spikelet s. 6. An axil tuft of hairs in inflorescences in some Poaceae, e.g. in Eragrostis comata. commercial name
The terminal inflorescence usually holds one, occasionally two flowers. Flowers are resupinate, with white, greenish, or reddish-brown bracts. The hermaphrodite, zygomorphic, tripartite flowers have three unfused, lanceolate sepals and smaller petals that point forward, forming a flower tube above the column.
The inflorescence is a single terminal umbel with 10–25(–30) outward-facing flowers on a flowering stalk up to 50 cm (20 in) high. Each flower has six tepals and six stamens . The tepals are white or greenish white, often marked with purplish brown or green speckles, each tepal being 5.5 to 8 mm (0.2 to 0.3 in) long and 2.7 to 4 mm (0.1 to ...
In most species that produce a determinate inflorescence in this way, all of the flower buds are formed before the first ones begin to open, and all open more or less at the same time. In some species with determinate inflorescences however, the terminal flower blooms first, which stops the elongation of the main axis, but side buds develop ...
Panicle – a raceme with branches, each branch having a smaller raceme of flowers. The terminal bud of each branch continues to grow, producing more side shoots and flowers. Pedicel – stem holding a one flower in an inflorescence. Peduncle – stem holding an inflorescence, or a single flower.
True sago palm is a suckering (multiple-stemmed) palm, each stem only flowering once (hapaxanthic) with a large upright terminal inflorescence. A stem grows 7–25 metres (23–82 feet) tall before it ends in an inflorescence. [3] Before flowering, a stem bears about 20 pinnate leaves up to 10 m (33 ft) long.
