242 S0MMER3 — NOVA SCOTIA COMPOSITE, A3TEES. 



surface dark green glaucus, lower paler, 1 J' to 2' smaller and entire 

 on the branches ; branches one or two flowered, heads large, rays 

 about twenty-five, spreading purple, twice or thrice larger than the 

 disk ; pappus copious, simple ; achasnia smooth,* scales of involu- 

 crum two rowed, outer longer and lax, all green lanceolate acute, 

 as long or longer than the disk, the outer sometimes bract like. 

 A rather handsome species, growing in dark, shady woods or by 

 watercourses, varying much in robustness and foliage according to 

 its situation. In some the branches are supplied with very small 

 leaves, in others they are nearly naked ; diagnosis doubtful ; 

 answers to puniceus of Linn., but absence of hairs and different 

 character of scales and number of rays, separates it from the typical 

 species; corresponds to A vimineus described in Wood's Class Book. 



A. longifolius. Larn. 



Smooth stem ; terete striate purple ; very much branched ; 

 branches spreading ; many flowered leaves; linear acute entire ; the 

 edges scabrous ; scales lanceolate, broad, acute, equalling the disk ; 

 irregularly two-rowed, loosely squarrose, herbaceous, often bract- 

 like; rays violet, twenty to thirty, showy, very long; pappus 

 simple ; achaenia smooth ; a handsome aster in fields and on road- 

 sides ; floweringin September and October; remarkable for its very 

 long, narrow, and acute leaves, which measure from 4' to 6' in 

 length by ^ in width ; the scales cause it to approach the above, 

 but the entire, very long, narrow, and acute leaves, the longer, 

 narrow, and more abundant ray-florets, and the absence of small 

 leaves on the stems, afford points for differential diagnosis. *Syno- 

 nymous with A. laxus TTilld. A. elodes. Torr. & Gr. 



Aster. — Sp. ? 



Stem striate, simple, leafy, branching at the top ; the branches 

 glandular, hairy, and forming a compound corymb ; heads numer- 

 ous, medium sized ; involucrum closely imbricated ; scales in three 

 rows, erect, narrow, acute, much shorter than the disk, rays all 

 white, twice longer than the disk ; fifteen to twenty, disk yellowish 

 rw purple brown, pappus equal copious ; leaves broad, lanceolate,
