14. MONESES Salisb.

Tax. note. — Our Pacific Coast plant, collected by Nuttall on the lower Columbia River in 1835, 

 was first described as Moneses reticulata by Nuttall in 1843 and defined more recently as Moneses 

 uniflora var. reticulata by Blake (Rhod. 17:28, — 1915) by reason of its "more ovate less orbicular 

 acute or acutish leaves serrate-dentate rather than crenate, characters by no means constant" and 

 which are further weakened, especially as to outline, apex and reticulation of the leaves, by the 

 series of Oregon and Washington specimens before us.
