S. bona-nox is a very prickly species, the leaves being spiny on their margins and underneath on the veins. Leaves, often narrowed in the middle, distended at base, pointed at apex, smooth and shiny. Flowers, numerous, in small umbels. Berries, bluish black, 1-seeded. Upright branches springing from root-stocks, which bear large tubers.

Thickets, Massachusetts to Florida and westward to Illinois, Missouri, and Texas.

(Most of our shrubs whose flowers appear in catkins will come under the category of green flowers.)
