Di- Graham's Description of New or Rare Plants. 345 



Mr Neill has a plant which in habit very much resembles this, but has 

 snathu ate undulate leaves, which are rather less stem clasping, and 

 Tve a greater number of nerves. It is probable that when ,t ffowers 

 it wUl prove to be a variety of this.

 flowers fall ; style neariy awanting ; stigma very small, blunt, simple, 

 glandular only on its upper surface. Seeds arranged in a single row in

 to extend from Hudson's Bay to the Rocky Mountams, and from Ca-

 both sides with stellate pubescence, giving tliem a greyish co our. Pe.. 

 dumles (2 inches long) opposite to the leaves, sohtary, near the extre-

 liaving generally 2, sometimes 3, ovate leaves distantly placed, and 

 smaller upwards, with a bud in the axil ot each, but only distmctly 

 evolved in the lower. Flowers small, subcapitiite ; pedicels short, and

 on the leaves or peduncles. Corolla white ; petals retuse, longer than
