44. Virgaurea. 45. vimiiiea. 46, * pnbenila. Stem sim- 

 ple and tt-rete, somewhat pubescent; leaves lanceolate, 

 entire, on eacli side minutely pubescent, attenuated at 

 eitlier extremity, radical ones subserrate; racemes spiked, 

 axillary, erect and condensed; peduncles pubescent; scales 

 of the culix linear-lanceolate, acute; rays elongated, about 

 10. Hab. !n the sandy fields of New Jersey, near Am- 

 boy. Sec. Stem brownish, 1 to 2 feet high, simple, and 

 pulverulently pubescent, as are also the leaves in a smaller 

 degree; racemes shorter tlian the lower leaves, collected 

 into a leafy spike, 4 to 6 inclies in length; rays conspicu- 

 ous and of a bright golden-yellow. The whole aspect of 

 the plant is that of .V. nemoralis, the inflorescence and up- 

 per attenuation of the leaves apart. 



47. jmdtiradiata. 48. elata. 49. rigida. The largest 

 flowered species in North America. 



* EuTHAMiA. f Calix cylindric-ovate, closely im- 

 bricated, scales agglutinated. 7?a(i/6r/ florets 10 to 

 20, very small, yellow. Recefitacle setose. Fafi- 

 Jius simple. Seed villous. 



Herbaceous; stems numerously branched, leaves nar- 

 row and very entire, longitudinally nerved; flowers ter- 

 minal, glomerated, glomeruli fastigiate, corymbose. Ca- 

 lix resinosely viscid. A subgenus, or rather genus, reci- 

 procally allied to Solidago and Chri/socoma. 



50. graminifolia. Chriisocoma graminifoUa, Lin. Solida- 

 go lanceolata, Alton. Stem and branches marginately an- 

 gular, angles and nerves on the under sidt- of the leaves 

 minutely hispid; leaves lanceolate-linear, entire, 3 to 5- 

 nervtd, margin scabrous; rays 15 to 20, minute, scarcely 

 exserted. Hab. From Canada to Virginia. 



51. teiudffjlia. S. iemiifolia. Ph. 2. p. 540. Stem low 

 and moie nunierously braiiched, angular, and as well as 



I tlie leaves smooth; leaves narrow linear, numerous, mar- 

 gin suLciliateiy scabrous, the upper surface covered with 

 resinous atoms, obsoletely 3-nerved; rays about 10, dis- 

 tinctly exserted. Hab. From New Jersey to Florida. 

 Axills of the leaves in imperfect plants oiten foliose. 



Solidago is exclusively a North American genus, with 

 the exception of 5 or 6 species in Europe, and 2 near 

 Canton in China. 'I"he arborescent species of 6t. Helena 

 and New Zealand will probably be excluded from this 

 genus, if ever carefully examined.
