C. pulvinata, Hook.f. 



Echeveria pulvinata, Rose, tned. 



Cotyledon pulvinata differs from the majority of its con- 

 geners in its branching habit, scattered leaves, spiciform 

 raceme and clothing of velvety, silvery, white hairs, which 

 turn brown on the branches, and are reflexed in age on the 

 leaves. It has slight claims to be placed in the genus 

 Echeveria of De Candolle, which is reduced to Cotyledon in 

 the " Genera Plantarum," but this rests only on the costato 

 corolla-lobes, for it has not the foliaceous sepals upon 

 which mainly the genus was established. But I under- 

 stand that Dr. J. N. Rose and Dr. N. L. Britton are 

 engaged on a revision of the whole of the North American 

 Crassulacese, and that they propose considerable generic 

 alterations by the creation of several new ones. There- 

 fore I will not further discuss the question of generic 

 limits here. 



The plant figured was received at Kew in 1900 from the 

 United States National Museum, Washington, and it 

 flowered in the Succulent House in March of the present 

 year.
