LOHG-PLUMED AVEHS 



summer. Originally produced by the union of Potentilla argyro- 

 phylla and Potentilla napaUnsis two Himalayan species, they have 

 now developed into a race of great beauty but, unfortunately, are 

 not quite hardy enough to be happy in our Northern climate. 

 The variations they display on the chord of red and orange are 

 simply marvellous. 



LONG-PLUMED AVENS. GEUM 



Geum trifibrum. 



Geum is a plant name used by Pliny. 



A perennial herb found principally in limestone regions, noticeable 

 for its showy head of plumed akenes, when in fruit. From Labrador to 

 Ontario and westward through the United States. 



Stem. — Low, softly hairy. 



Root-leaves. — Interruptedly pinnate; leaflets numerous and crowded, 

 oblong-wedge-form, deeply cut-toothed. 

 Flowers. — Three or more on long peduncles. 

 Calyx. — Campanulate, five-cleft. 

 Petals. — Five, oblong, purplish. 

 Stamens. — Many. 

 Carpels. — Many; styles long, strongly plumose, and feathery in fruit. 



The Long-Plumed Avens is an exceedingly pretty but rare 

 plant of Northern range. The clustered akenes feathered with 

 long silvery hairs are more noticeable than the flowers. 



This sppcies belongs to the same type as Geum chiloense, the 

 best of the cultivated forms, which is a favorite in rock gardens 

 because of its double blossoms and brilliant colors. The heads 

 of these fruiting carpels also bear long and plumy styles. The 

 plant comes from Chili.
