OF NORTH A>IERICA. 75 



deeply 5fi(l colorate villose, petals 5 equal ve- 

 nose, stamens 20 inserted on a torus adnate to 

 the base of calix, pistils 5 equal sessile, capsu- 

 les 5 sessile tomentose monospei :n. Habit of 

 the paniculate Splreas, I have adopted this 

 Genus and name on the suggestion of Lindley, 

 who proposed to unite to it the next, but the' 

 habit is too different. Schizonotus appears to 

 mean Split back and I do not know how it ap- 

 plies unless the capsules open outside.

 lobate and laciniate serrate, white villose be- 

 neath, flowers terminal paniculate racemose, 

 pedicels and calix villose, petals oblong with 3 

 veins — Origon region and Mts. A very pecu- 

 liar shrub, quite different from my Thecanisia 

 discolor 297, to which I refered by mistake the 

 Sp. discolor of Pursh, flowers white, leaves cal- 

 led elliptic by Smith, ovate by Pursh and Torrey 

 but they are realy ovate oblong.

 sile smooth monosperm. Large shrubs with 

 the foliage of Roses and Sorlms, leaves alter- 

 nate stipulate oddlij pinnate^ Jolioles oppo- 

 site sessile, flowers bracteolate paniculate or 

 corymbose — This line natural Genus is certain- 

 ly more diflerent from Spirea than Lowea is 

 from Rosa ! it may be known at first sight by 

 its habit.
