438 ERICACE^. Rhododendron. 



Swamps, particularly tliose in which the White Cedar {Cupressus thuy aides) abounds ; 

 but sometimes in rather dry situations. Near Babylon, &c., Long Island ; in the Highlands 

 of New- York ; Oriskany swamp {Dr. Knieskern). Fl. June - July. Fr. September. A 

 magnificent shrub, and susceptible of cultivation without much difficulty, especially if removed 

 from dryish soils. I have sometimes found large crystalline grains of white sugar in the 

 flowers. ' ^^
