Medium-sized
plant, a few feet tall. Basal leaves, with five to seven leaflets
arranged like the fingers of a hand (palmately). Each leaflet with
several lobes and each lobe coarsely toothed. Upper leaves similar, but
may have only three lobes. Flowers in small clusters of clusters, the
smallest cluster being called an umbellet. Umbellets are of two kinds.
One kind has three perfect flowers, that is flowers that have both male
and female parts, and a small number of flowers with male parts only
(called staminate, since male parts are stamens). The other kind of
umbellet has only staminate flowers. The picture at right in the middle
row shows an all-staminate umbellet. The picture at left in the
bottom row shows a staminate umbellet on the right, and a mixed
umbellet on the left. The perfect flowers have a bristly ovary at the
base, and two long female parts called styles that are longer than the
bristles and stick way out. Flower have rounded triangular green sepals
and yellow petals. The stamens are yellow (lowest row, center), turning
brown with age (lowest, left). The perfect flowers develop into round
fruits covered with hooked bristles and having the two styles
persisting on top, as seen in the lowest row right. The staminate
flowers lose their stamens and petals and persist only as sepals, as
seen lowest right. The remnants of the staminate flowers are shorter
than the fruits.
A native of most of eastern North
America as far west as Texas to North Dakota. It likes shady, moist
forests. In Wildwood, there is a concentration near the two small foot
bridges on the Westside Trail (see picture at left), and another at the
juntion of the Eastside Trail with the pave Riverway, near the
bathroms, but is also found elsewhere.
The palmately
three-to-seven-parted leaves with their lobes and teeth and the small
flowers in clusters of clusters make snakeroots or sanicles fairly easy
to recognize. However, there are at least three species in Wildwood. To
definitively identify them, you will need a hand lens. Key characters
for Clustered Snakeroot are the yellow flowers, the styles that stick
way out and persist on the fruit, the male flower remnants smaller than
the fruit, and the rounded triangular sepals. Black Snakeroot (S. marilandica)
also has styles that stick out and curve back in fruit, but it has
white flowers, pointed sepals, and male flower remnants as long or
longer thant the fruits. Canada Snakeroot (S. canadensis) has small white flowers and neither the stamens nor the styles stick out of the flowers. |
