 leaves, smooth on both surfaces, beneath covered with resinous scales.

 obtuse, but mucronulate, long petiolate, smooth on both surfaces, beneath 

 paler and resinosely atomiferous; capsule globose-ovate. 



Hab. In the central chain of the Rocky Mountains, on the sides of the moimtains which close up 

 Thornberg's ravine, growing in extensive thickets, the bushes four to six feet high, and as large as 

 those of Kalmia latifolia. Bark brown and smooth. Branches coming out in circles at length from 

 the base of former corymbs. Leaf an inch to an inch and a half long, three quarters of an inch wide; 

 petiole half an inch long. Every part of the plant in a young state, except the corolla and upper 

 surface of the leaves, scattered with shining yellow resinous scales. Leaf paler beneath, dark 

 green above. Peduncles one half to three quarters of an inch long, corymbose. Calyx five-lobed, 

 small, the segments oval, obtuse, ciliated. Corolla of five white, broad, oval petals. Stamens 

 ten, filaments long, subulate, pilose below; anthers oblong biporose. Style about the length of

 pubescent as well as glandular and scaly, five-celled, five-valved, the axis pentangular, dehiscing at 

 the base. Seeds numerous, subulate, alated at either end. Quite similar, but smaller than in L.
