Andromeda speciosa var. pulverulenta Michx. Fl. Bor. Am. 1:

Fruticose, glabrous and prominently glaucous throughout; 
leaves subcoriaceous, elliptical, entire or obscurely serrulate, 
slightly cuspidate, acute when young, becoming obtuse; length 
5.5 to 6 cm., width 2.5 to 3 cm.; calyx somewhat campanulate, 
its lobes closely appressed to the corolla, and with the peduncle 
glauco-pulverulent; corolla with lobes more acute than in cassine- 
Solia.. 
Same range as the last, but less common. 
This species was figured by Bartram,* who evidently considered 
it worthy of something more than varietal rank, although he did 
not describe it. Michaux placed it under his Andromeda speciosa, 
and his example was followed by Pursh,+ who remarks in a note 
on speciosa: “1 certainly must epincide with Michaux’s idea of A. 
_ pulverulenta being only a variety, as I very frequently have seen 
intermediate varieties and even had the trace of bothon one plant.” 
While it is true that Z. pulverulenta exhibits a variable degree 
of glaucosity, there are other characters which, on careful examin- 
tion, serve to separate it from cassinefolia. The calyx in the one 
case is campanulate, inthe other spreading, with smaller lobes, the 
leaves are elliptical, and not oblong-ovate; and the peduncles in 
pulverulenta are always prominently glauco-pulverulent, giving the 
plant a very distinctive appearance. It is also possible that the 
two species may hybridize, as they occur throughout the same 
range, and this would explain the various forms which Pursh 
claims to have seen on the same plant.
