careful examination of the so-called Casstopc stclleriana makes 

 it clear that this species is not a true Cassiope but should be 

 made the type of a hitherto undescribed genus, which is charac- 

 terized as follows : 



Harrimanella gen. no v. 



Plant belonging to the tribe Andromedeae, of the family Ericaceae ; 

 leaves empetriform, many-ranked, decurrent ; flowers pentamerous, 

 nodding, singly terminal on ordinary leafy branches ; calyx ebracteo- 

 late, the sepals distinct, imbricated in the bud, not becoming fleshy

and not exceeding the capsule in fruit ; corolla campanulate, vertically 

 pL>ited at the base, the lobes pendent and overlapping; filainents 

 tumid below, the broad anthers situated in two planes of five each, 

 biaristate below the apex, opening by large pores ; style short, stout, 

 ovoid, persistent on the fruit ; capsule globose, many-seeded ; seed 

 oblong, slightly or not at all winged. 



The genus is named for Mr. E. H. Harriman, of New York, through 

 whose courtesy the opportunities and pleasures of his voyage to Alaska, 

 in 1899, were shared by a party of scientific investigators. It is hoped 

 that the Alaska heather, Harrimanella stellcria7ia, one of the most 

 charming and beautiful little plants of the whole Alaskan flora, will 

 serve as a happy reminder of the expedition to all its members. 



The genus Cassiope, from which Harrimanella is now segregated, 

 has opposite, cuprcssiform, closely sessile leaves, conspicuously swollen 

 or spurred at the base and closeh*^ appressed to the stem, the branches
