A European plant with compound umbels of small, white flowers and finely divided leaves. A branched perennial, 2-6 feet tall. Stems are hollow, grooved; purple-spotted. Leaves are carrot-like, but in overall outline more like an equilateral triangle, and with more divisions; leaves ill-scented when bruised. Leafstalks are hairless.

Hemlock spruce:

A North American evergreen tree growing 50-100 feet high; the bark is a dull brownish-gray on the outside and red underneath and is made up of large, rough scales. The leaves are short and needle-like, and both male and female flowers grow in catkins. The woody seed cones are less than an inch long. Needles are flat; 5/16-9/16 inches long; on short slender stalks. Needles are bright green above, silvery whitish beneath. Cones drooping, to 1 inch long, with few scales; scales rounded. The oleoresin derived from the bark is dark reddish brown, opaque, and has a characteristic turpentine-like fragrance. This is the kind of bark tanners use in making shoe leather.
