from JNordfjord in Disco which were 

 about 35 cm. in length. A dwarf 

 specimen is shown in Fig. 18. 



There are five reddish-brown, hairy 

 perigone -leave s and five yellow 

 nectary-leaves about twice as, long 

 as the perigone- leaves. The receptacle 

 is almost globular in form but elon- 

 gates somewhat during fruit-setting, 

 not so much, however, as in R. ni- 

 valis. These two plants, R. sulpJiu- 

 reus and R. nivalis agree very closely 

 but are distinguished from each other 

 especially by the fact of R. sulph. 

 having short, reddish-brown hairs 

 upon the torus, while they are absent 

 from R. nivalis (Simmons 1. c). The
