Smallanthus uvedalia

Smallanthus uvedalia, known as hairy leafcup, bear's foot, and yellow flower leafcup, is a herbaceous perennial native to the Central and Eastern United States. It is a member of the family Asteraceae, commonly referred to as the aster, daisy, composite, or sunflower family. [1][2]

Description

Hairy leafcup is 0.6 to 3.0 m (24 – 118 in) tall. The stem is stout and generally smooth below the inflorescence branches. The opposite leaves form a small cup around the stem and hence the name leafcup. Each head has 7 to 13 yellow, 1 – 2 cm (3/8 to 3/4 in) long ray flowers to the outside, and 40-80 or so yellow tube-like disc flowers to the inside. A single large plant may produce one hundred or so heads. The entire plant has a resinous odor.[1]

The species was formerly named Polymnia uvedalia (Linnaeus) Linnaeus.[3]

gollark: I see.
gollark: This is just a bad implementation of a "boost converter", so just look up that.
gollark: The capacitor smooths the very wobbly lines into nonwobbly lines.
gollark: The transistor switches the inductor between being connected to the voltage source's other end and being connected to it only through the diode and capacitor and resistor and such. The inductor "wants" to keep the current through it constant. When it's connected to the other end of the voltage source, it's "charging", and when it is disconnected there is a voltage across it slightly bigger than the voltage source's voltage, which causes a current through the left side of the circuit.
