Dense cluster of sessile or subsessile flower s or floret s, e.g. a flower head in the daisy family Asteraceae. See pseudanthium. capsule Dry fruit formed from two or more united carpel s and dehiscing when ripe (usually by splitting into pieces or opening at summit by teeth or pores). carduoid
A ray flower is a two- or three-lobed, strap-shaped, individual flower, found in the head of most members of the Asteraceae. [15] [16] The corolla of the ray flower may have two tiny, vestigial teeth, opposite to the three-lobed strap, or tongue, indicating its evolution by fusion from an ancestral, five-part corolla. In some species, the 3:2 ...
The flat upper part (or limb) is line-shaped, 1 + 1 ⁄ 8 – 1 + 7 ⁄ 8 cm (0.48–0.72 in) long, with four veins, ending with three teeth. The style of each ray floret is up to 6 + 1 ⁄ 2 mm (about 1 ⁄ 4 in) long, the upper 1 + 1 ⁄ 2 mm (0.06 in) is split into two line- to ellipse
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);
Each ray floret has three petals which are fused together to form a corolla. The floret has one ovary at the bottom, and this ovary contains one ovule. [m] The ovary has an attached style that extends outward from between the ray floret corolla and the rest of the flower head. As the ray floret is blooming, the stigma at the top of the style ...

The edges of the leaves generally have tiny widely spaced teeth. The inflorescence is a large dense cluster of many very small flower heads, sometimes over 300 in one cluster.
