NOTES OX SEDUM 51 



I believe in the Sierra Nevada, but the locality is not stated in 

 his Catalogue (for 1913), and the finder is not at present accessible. 

 This form is so distinct that it deserves varietal rank. It is well 

 distinguished by its densely imbricate leaves and abundant very large 

 flowers, which in diameter are 1^ times that of the type. 



Typo major ; folia ramorum sterilium dense imbricata, obovata, 

 apice obtuse acutata, basi cuneata, dense glanduloso-hirsuta, car- 

 nosissima, supra plana ; inflorescentia quam in typo major, ramosior ; 

 Hores ampli, 11 mm. diametro, petalis 5-7 (plerumque 6). 



The plant flowers in the garden in late July, six weeks later than 

 the type. 



Series Spathulifolia.
