11. TURRICULA J. F. Macbride, Contr. Gray Herb. No. 49:42. 1917. 



Stout, erect, glandular and ill-scented perennial herb, woody and branched at base. 

 Leaves alternate, thin, toothed or entire, sessile. Flowers numerous in a terminal, thyrsoid 

 panicle of scorpioid, subsessile cymes. Calyx divided nearly to the base, the lobes sub- 

 equal. Corolla purple, deciduous, funnelform, longer than the calyx, shallowly lobed. 

 Stamens unequal, included, inserted on the base of the corolla-tube, the filaments adnate 

 to the corolla-tube ; appendages obsolete. Style divided to the base. Mature capsule mem- 

 branaceous, falsely bilocular by the intrusion and union of the narrow placentae, both 

 loculicidally and septicidally dehiscent into 4 valves. Ovules 6-8 in each locule. Seeds 

 6-10, oblong-ovoid, black, longitudinally striate with fine ridges and minutely transversely 

 reticulate. [Name Latin, meaning little tower.] 



A monotypic genus of the southwestern United States and Lower California, sole species, Nama Parryi A.
