in the cultivated parsnip, or it could be a more recent introduction from Europe.

Plants are up to five feet tall with grooved stems and compound leaves. The entire plant when crushed (but don’t crush it without gloves) smells like celery or carrot. Like its other relatives in the parsley family, it has flat-topped inflorescences (flower clusters). Wild parsnip has masses of small yellow flowers in midsummer. Fruits are flattened and resemble fennel seed.

All parts of the plant contain compounds that cause phyto-photodermatitis induced by contact with the plant. These irritants are absorbed into the skin and when activated by light, initiate a chemical transformation causing swelling and blisters. This reaction is not an immune response but rather a contact poison, so it operates in a manner different from that of poison ivy.

Wild parsnip is difficult to control because of its large, persistent root, which requires digging for effective removal.

Zizia aurea (L.) Koch, common golden Alexanders (Apiaceae) Golden Alexanders occurs in rich, mesic forests (those with a moderate amount of moisture), in floodplains, and moist fields. Individual flowers are bright yellow, one-eighth of an inch in diameter, and arranged Š 2019 The Johns Hopkins University Press UNCORRECTED PROOF Do not quote for publication until verified with finished book.

Plants often grow in patches and can reach two feet in height.

At first glance, this species might be confused with the wild parsnip, Pastinaca sativa, but the latter species is taller, flowers later, and has more leaflets per compound leaf.

A homeopathic medicine is derived from the root. Golden Alexanders is a host plant to black swallowtail butterfly larvae.

The genus is named after J. B. Ziz (1779-1829), a German botanist.

Asclepias tuberosa L., butterfly weed (Apocynaceae)

Unlike its milkweed relatives, butterfly weed has alternate leaves and lacks milky latex (juice). It is easily recognized by its bright orange flowers that appear throughout most of the summer. Butterfly weed is also different from most other milkweeds in that it can branch from the base and produce a solid clump of many flowering stems. Its ease of cultivation and attractive, long-blooming flowers make it a popular garden Š 2019 The Johns Hopkins University Press UNCORRECTED PROOF Do not quote for publication until verified with finished book.

by removing leaf litter around the plant and finding the tiny buds borne on a sharply recurved stalk. The fruit is technically edible, with a taste that with some imagination resembles that of a raspberry. However, it would take at least ten fruits of the dewdrop to equal the size of a single raspberry.

Recent research has placed dewdrop in the genus Rubus, a group that includes blackberries and raspberries, replacing the more familiar name Dalibarda repens L.

Sibbaldia tridentata (Aiton) Paule & Soják, three-toothed cinquefoil (Rosaceae)

Rocky ridges, alpine meadows, and rocky outcrops are the habitat of this cinquefoil, so named because most species have a five-parted leaf—cinquefoil in French. It appears to be an herbaceous plant but is technically an evergreen creeping subshrub. Like many alpine tundra plants, its leaves are borne close to the ground. Leaves are three-parted, shiny, thick, and © 2019 The Johns Hopkins University Press UNCORRECTED PROOF Do not quote for publication until verified with finished book. All rights reserved.

Mitchella repens L., partridge berry (Rubiaceae)

The coffee family, Rubiaceae, is one of the five largest plant families, largely tropical in distribution and a small component of the Adirondack flora, with only five genera. The only evergreen member of the family here is partridge berry, a common plant in a diversity of habitats throughout the region. The genus is named after a colonial Virginia physician, John Mitchell (1711-68), best known for his map-making skills.

This is a winsome, miniature vine that can form large colonies through its ability to root and branch. Attractive white © 2019 The Johns Hopkins University Press UNCORRECTED PROOF Do not quote for publication until verified with finished book. All rights reserved.
