Liatris novae-angliae Northern blazing star is endemic to the northeastern United States, and is rare and protected in most of New England. The sandplain grasslands and coastal heathlands where it occurs were typically prevented from becoming wooded by sea spray, grazing, and fires. Controlled, prescribed burns are now used to maintain some of this habitat. Blooms late summer and early fall; flower heads pink-purple, 3/4-1 in. wide, short-stalked, arranged in spikelike racemes (disk flowers only); the bracts below the heads blunt and darkened at the tip. Leaves 4-12 in. long, crowded, liner or narrowly lance-shaped. Stems hairy or smooth. ASTERACEAE |

Symphyotrichum concolor Eastern silver American-aster, a fire-adapted species of sand-plains and pine barrens of the coastal plain, is rare and declining in New England, where it is found only in Massachusetts and Rhode Island. Description: Aster concolor is a slender, herbaceous perennial forb, growing 3 dm to 10 dm in height. Simple or sparingly branched, loosely prostrate stems arise singly or in small numbers(3-20) from a thickened, rhizomatous root crown or caudex. The sericeous leaves are lanceolate or oblong to broadly elliptic to 5 x 1.5 cm, and are sessile but not clasping. Leaves often have a silky, hence silvery, appearance and are smooth to the touch. The inflorescence is narrow and racemiform, and occasionally the inflorescence has racemiform branches. Each head bears eight to 16 female ray flowers, 7-12 mm in length. Aster concolor is the only lilac flowered (bluish pink) aster in our region. Its distinctive, showy lilac rays surround monoecious disk flowers that are white prior to anthesis and later darken to purple following pollination.Achenes are densely sericeous. Aster concolor is a fall-blooming species. In Massachusetts it begins to emerge from the surrounding grass cover by mid-August and blooms late in the season, from September to early October.

Pityopsis falcata Sickle-leaved golden-aster is a highly restricted endemic, found on sandy glacial deposits left behind by the Wisconsin glaciation.

Leaves are simple and alternate; It can be easily identified by its slender, curved, “sickle-like” leaves (simple, alternate). ASTERACEAE |
