 spikes or racemes. Calyx 5-parted or S-cleft, the segments or lobes narrow. Corolla funnel- 

 form or salverform, 5-Iobed, naked, pubescent or crested in the throat, the lobes entire or 

 erose-denticulate, the tube sometimes pubescent at the base within. Stamens 5, included, 

 inserted on the throat of the corolla; filaments short. Ovary 4-divided ; style slender, or 

 filiform; stigma capitate, or 2-lobed. Nutlets 4. or fewer, erect, white, smooth and shining, 

 or brown and wrinkled, attached by their bases to the nearly flat receptacle, the scar of 

 attachment not concave. [Greek, stone-seed, from the hard nutlets.] 



About 40 species, natives of the northern hemisphere, a few in South America and Africa. 

 Besides the following, some 7 others occur in the southern and southwestern parts of the United

Leaves ovate, acuminate; nutlets globose-ovoid. 3. L.latifolinm. 



Corolla dull yellow, its tube longer than the calyx ; leaves lanceolate ; flowers dense. 4. L. pilosum. 

 Corolla bright yellow, its tube much longer than the calyx; flowers dense; red-rooted perennials.
