The ray floret is female with one pistil containing one style, two stigmas, and an ovary with one ovule. Labeled parts are as follows: Labeled parts are as follows: 1 – corolla (petals) (three petals are joined to form a strap, and in the case of 5 petals, they form a ligule);
A typical Asteraceae flower head showing the (five) individual ray florets and the (approximately 16) disk florets of a specimen of (Bidens torta) In plants of the Asteraceae, what appears to be a single "daisy"-type flower is actually a composite of several much smaller flowers, known as the capitulum or head.
Symphyotrichum simmondsii is a colony-forming herbaceous perennial that grows 10 centimeters (4 inches) to 120 cm (4 ft) tall from long rhizomes.The flowers have an average of 18–38 pale lavender or lilac to pale purple petals, also called rays or ray florets.
The 15–33 ray florets are blue, pink, purple, or white, with a length averaging 5–7 mm (1 ⁄ 5 – 3 ⁄ 10 in) [c] and width of 1–1.7 mm (1 ⁄ 24 – 1 ⁄ 16 in). [5] Ray florets in the Symphyotrichum genus are exclusively female, each having a pistil (with style , stigma , and ovary ) but no stamen ; thus, ray florets accept pollen ...
Ray florets in the Symphyotrichum genus are exclusively female, each having a pistil (with style, stigma, and ovary) but no stamen. Ray florets accept pollen and each can develop a seed, but they produce no pollen. [6] The ray florets of S. lateriflorum bloom earlier and are likely receptive to pollen longer than the disk florets. [15]
These ray florets are about 6 mm (¼ in) long and 1½ mm (0.06 in) wide, with glandular hears on the tube shaped base. The disc florets are about 4 mm (0.16 in) long and also have a glandular tube. Within the ray florets are five anthers merged into a tube through which the style grows while gathering the pollen on its shaft.
Calendula officinalis, the pot marigold, common marigold, ruddles, Mary's gold or Scotch marigold, [2] is a flowering plant in the daisy family, Asteraceae.It is probably native to southern Europe, but its long history of cultivation makes its precise origin unknown, and it is widely naturalised.
The flower heads are yellow, small with only 4–5 yellow ray florets. [6] [2] 1 cm (1 ⁄ 2 in) wide more or less, on branches 90 degrees to the main stem, in loose panicle. [7] It flowers from June until September. [8] Lactuca muralis is similar to Lactuca serriola L. and Lactuca virosa L. but clearly distinguished by having only 5 florets. [9]
