17_2. SOLIDAGO. 49. 55. 

 1. Flowers one-sided. Leaves with three combined nerves. 



canaden"sis (Canadian golden-rod. O. y. Ju. 4), stem downy ; le'aves lanceo- 

 late, serrate, rough ; racemes copious panicled, recurved ; rays hardly longer 

 than the disk ; stem angular ; leaves sessile, three inches long, sometimes 

 nearly entire. 2 5 f. &. 



gigan"tea (giant golden-rod. O. y. Au. 4,) stem erect, glabrous ; leaves lance- 

 olate, smooth, serrate, rough-edged, obscurely 3 nerved ; racemes panicled ; 

 peduncles rough-haired ; rays short. 4 7 f. S. 



lateriflo'ra (side-flowered golden rod. y.' Au. 4), stem erect, a little hairy; 

 leaves lanceolate, slightly 3 nerved, glabrous, rough-edged ; lower ones sub- 

 serrate ; racemes panicled, a little recurved, sub-secund ; flowers large, the

 2. Racemes or flowers one-sided. Leaves veiny. 



<iltis"sima (variable golden-rod. O. y. Au. 4), stem erect, ro;gh-haired ; leaves 

 lanceolate ; lower ones deeply serrate, scabrous, rugose. The panicled ra- 

 cemes are very numerous and spread eveiy way, so as to bring the one-sided 

 flowers upwards ; rays half as long again as the calyx. But this species is 

 so variable that students generally endeavour to make several species of it. 

 The serratures of the leaves are equal and unequal ; it is hairy or villose ; 

 and sometimes the racemes diverge but little. 3 6 f. . 



pat"ida (spread golden rod. O. y. S. 4), stern erect^, glabrous ; leaves oval, ser- 

 rate, glabrous ; radical ones oblong-spatulate ; racemes panicled, spreading ; 

 peduncles pubescent. Stem wand-like, angular and striate ; stem-leaves
