The erect flowering stem is 15–40 cm (6–16 in) long, with a terminal raceme of 15–50 flowers. The flowers are white, small and feathery, giving the flower cluster a fuzzy appearance. Each flower has 5 sepals, 5 petals, and 10 long, slender stamens (which are longer than the petals). The two unequal seed capsules split along their inside ...
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
On a Phalaenopsis, a keiki is a small plant growing from one node along the flower stem. Keiki growth may be induced by prolonged exposure to high temperatures during the final phase of spike growth. [1] On a Dendrobium, the keiki is typically found sprouting along the length of the cane or from the end of the cane.
Magnolia grandiflora, a spiraled flower.. Depending on the family considered, the pieces of the flower can be arranged on the receptacle in two different ways. In the case of the spiral arrangement, the parts are inserted consecutively and at different levels, describing a spiral on the axis in the same way as the leaves are inserted on the stem.

Close-up of flowers of Phyteuma orbiculare. Phyteuma orbiculare reaches on average 20–50 centimetres (7.9–19.7 in) of height. A deep blue, almost purple wildflower that is not as it seems: each head, rather than being a single bloom, is actually a collection of smaller ones, huddled together.
The stem can also be called the culm, halm, haulm, stalk, or thyrsus. The stem is normally divided into nodes and internodes: [2] The nodes are the points of attachment for leaves and can hold one or more leaves. There are sometimes axillary buds between the stem and leaf which can grow into branches (with leaves, conifer cones, or flowers). [2]
Teasels are easily identified with their prickly stem and leaves, and the inflorescence of purple, dark pink or lavender flowers that form a head on the end of the stem(s). The inflorescence is ovoid, 4–10 centimetres (1.6–3.9 in) long and 3–5 centimetres (1.2–2.0 in) broad, with a basal whorl of spiny bracts .
