SOLENOSTEMON (Greek, tube and thread, refer- 

 ring to the fact that the filaments are grown together, at 

 their base, into a tube). Labiaise. Erect herbs allied to 

 Coleus, probably similarly used: Ivs. ovate, crenate, 

 long-petioled: whorls of fls. laxly 6- to many-fld., 

 arranged in long racemes or panicles: fls. small; calyx

 edges, lateral small, lower oblong, as long as the upper; 

 corolla-tube exserted, slender, dilated and oblique at 

 the throat, the limb 2-lipped, upper shorter, lower long, 

 oblong, slightly concave; stamens 4, the filaments 

 united at then- base into a tube; disk glandular: nutlets 

 ovoid, smooth. Eight species, W. Trop. Afr.; one

 Leb.). Herb, up to 2 ft. high, branches 4-angled: Ivs.

SOLIDAGO (according to Gray, from "solidiis and 

 ago, to make solid or draw together, in allusion to 

 reputed vulnerary properties"). Compdsitse. GOLDEX- 

 ROD. Perennial herbs very useful for borders and for 

 colonizing, but little known in the trade. 



Erect, of various habit, with simple alternate Ivs. 

 and many small yellow (rarely whitish) heads in spikes, 

 thyrses, compound panicles, or racemes: heads oblong 

 or narrow-campanulate, with small mostly appressed 

 scales, containing few florets, the disk-florets all per- 

 fect and the ray-florets in one series and pistillate: 

 pappus of 1 or 2 rows of roughish capillary bristles. 

 The genus is characteristic of E. X. Amer.. where about 

 60 species occur. There are several species on the 

 Pacific coast, a few in Mex. and S. Amer., and 2 or 3
