CLASS XIII. ORDER I. 221 



Geum strictum. Willd. Yellow Avcns. 



Hairy; leaves all interruptedly pinnate, leafets 

 ovate, toothed, the terminal one largest ; flowers erect, 

 petals longer than the calyx. 



A tall, hairy species with yellow flowers. Terminal leafet 

 large. Alternate segments of the calyx linear. Flowers yel- 

 low. — On Prospect hill, Charlestown. — June. — Perennial. 



In a specimen gathered in Bretton woods, near the White 

 mountains, the stem leaves are trifld and the petals hardly longer 

 than the calyx. — Perhaps a new species. 

 Geum Peckii. Pursh. Peck's Geum. 



Leaves ren I form, 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, reniform, 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 flowers- 

 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 on the summit of the 

 While mountains. Very distinct from Geum montanum, with 

 which I have compared it. Pursh, probably from seeing bad 

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

 ling the calyx. — July. 



Class XIIT. POI-YANDRIA. Many sta7nens. 

 Order I. MONOGYNIA. One style. 

 228. Chelidonium. Calyx two leaved ; petals four
