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.

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 ...
The terminal inflorescence is three to thirty flowered. The branching of the inflorescence is mostly dichasial , with ascending pairs of flowering branches rising five nodes below. The entire inflorescence is corymbiform to cylindric, though in smaller plants the inflorescence is a simple, nearly naked cyme .
Some inflorescences are composed of many small flowers arranged in a formation that resembles a single flower. A common example of this is most members of the very large composite group. A single daisy or sunflower, for example, is not a flower but a flower head—an inflorescence composed of numerous flowers (or florets).
Pedicel – the stem or stalk that holds a single flower in an inflorescence. Peduncle – the part of a stem that bears the entire inflorescence, normally having no leaves, or the leaves having been reduced to bracts. When the flower is solitary, it is the stem or stalk holding the flower. Peduncular – referring to or having a peduncle.
The terminal inflorescence is a raceme at the end of a long peduncle covered from its base by close, imbricating sheathes; sometimes additional racemes will arise from the nodes of the peduncle. The flowers typically contain significant amounts of chlorophyll and yellow pigment—these are often accompanied by enough purple pigment to give the ...
