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 ...
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.
The plant grows 3-8 feet tall with an unbranched stem until reaching the inflorescence at the very top. [5] Its yellow flower heads, which bloom in late summer through early fall, are 1-2 inches wide and consist of up to 10 bright yellow ray florets that are angled downward, each bearing a notch at the end, as well as a spherical cluster of ...
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 plant produces an erect, unbranched flower stem, occasionally to 40 centimeters in height, but typically much shorter. A non-flowering shoot bears one smooth, waxy, shiny leaf up to 10 centimeters long and 5 to 8 cm broad, hence its scientific name (dilatatum means 'broad'). The leaf is oval in shape with a heart-shaped base.
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 .
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
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]
