 "High alpine." 144. 0. multiceps, Nutt. in Torr. and Gray, Fl. (Physo- 

 calyx multiceps, Nutt. in herb. Acad. ) " Subalpine and lower." This is Dr. 

 Parry's No. 191, which I wrongly referred to 0. nana, Nutt. The plant is 

 more dwarf and the leaflets much smaller than in Nuttall's specimens, which 

 are in fruit only, while ours, last year in blossom only, now show the young 

 fruit in the bladdery calyx. It is a very pretty plant. 146. Sophoea sericea,
