Encyclopedia
Thalictrum fendleri is a species of flowering plant in the buttercup family
known by the common name Fendler's meadow-rue. It is native to western North America, including much of the western United States and northern Mexico. It is a common plant found in many types of habitat. It is a perennial herb growing erect to one or two meters tall. The hairless stems are green to purple in color. The leaves have compound blades divided into a few or many segments of varying shapes, often with three lobes, and are borne on long, slender petioles
. The blades are hairless to slightly fuzzy and glandular. The inflorescence
is an upright or arching panicle
of flowers. The species is usually dioecious
, with male and female flowers occurring on separate plants, but plants with bisexual flowers have been noted. The male flower has a bell-shaped calyx of four sepal
s in shades of greenish white or purple which may lighten to white with age. From the calyx dangle many long, yellow or purple stamen
s tipped with large anthers. The female flower has a cluster of immature fruits tipped with styles
