22 Addisonia 



angled, the sharp angles somewhat winged. The leaves are oppo- 

 site; their blades are ovate, acuminate, uniformly serrate, slightly 

 paler beneath, and abruptly narrowed to slender petioles. The 

 flowers are borne on slender upcurved pedicels, which like the upper 

 part of the stem bear sparse minute gland-tipped hairs. The sepals, 

 corolla-form, stamens, and pistil are nearly as in A. meridionalis 

 (plate 150) ; however, the corolla is pure white, with three violet-red 

 lines, the filaments bear anthers with less expanded sacs, and the 

 style is slightly longer. The capsule is narrowl}^ pyramidal, one 

 half inch long, and opens near the apex by four slits, which divide 

 both the septum and medianly the outside wall of each cavity. The 

 seeds are small, oval, black, ridged and, escaping through the 

 capsule-mouth, are distributed as described for A. meridioytalis.
