Vancouveria chrysantha
Encyclopedia
Vancouveria chrysantha is a species of flowering plant in the barberry family
known by the common names golden inside-out flower and Siskiyou inside-out flower. It is native to southwestern Oregon
and northwestern California
, where it occurs in coastal and inland mountain ranges, including the Klamath Mountains
. It grows in dry mountain habitat in chaparral
and forests. It is a rhizomatous
perennial herb with a short, mostly underground stem. It produces a patch of basal leaves which are each made up of round, shallowly lobed leaflets borne on long, reddish petioles
. The inflorescence
appears in the spring to early summer. It is a raceme
of flowers on a long, erect peduncle
with hairy, glandular branches. Each drooping flower has six inner sepal
s which look like petals. They are bright yellow, up to a centimeter long, and reflexed back, or upwards, away from the flower center. Lying against the sepals are the smaller true petals, which are also bright yellow, curled, and hood-like. There are six stamen
s and a large glandular ovary

Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...
