208 Class XIII. Order I. 



GEUM PECKII. Pursh. Peck's Geum. 



Leaves reniform, the petiole pinnately appendaged ; 

 flowers several on a stalk ; petals twice as long as the 

 calyx. , 



Root leaves large, pinnate, the lateral leafets minute, terminal 

 one very large, renifprm, cut and toothed, glabrous, slightly cili- 

 ate. Petioles long, ending in broad ciliate stipules. Stem 

 round, pubescent, four or five inches high, furnished with a few 

 small, cut, and toothed leafets, and bearing from one to five flow- 

 ers. Calyx segments acute, the alternate ones minute and linear. 

 Petals orbicular, yellow, twice the length of the calyx. Sta- 

 mens numerous, slender, yellow. Styles very short. Seeds 

 hairy. Awns erect, slightly hooked at tip. 



Discovered by the late Professor Peck oji the summit of the 

 White mountains. Very distinct from Geum montanum, with 

 which I have compared it. Pur-sh, probably from seeing bad 

 specimens, represents it as one flowered, and with petals equal- 

 ling the calyx. July. 



Class XIII. POLYANDRIA. Many stamens. 

 Order I. MOJi^OGYNM. One style.

 four; silique superior, two valved, one celled, linear ;

 ry one celled, many seeded ; seeds nearly flat.

 smaller ; capsule superior, three valved, opening at top.
