NOTKS ON THE AHOVE LlST. 



Conius PurpHsi, Koehne ' is a recent segregate of C. Amommn 

 Miller {C. sericca, L.) and was first described from plants raised in 

 Germany from seeds collected near Toledo, Ohio, by C. A. Purpus. 

 It is chiefly distinguished from C. Amomum by the numerous papillae 

 on the epidermis on the under side of the leaves which appears there- 

 fore glaucous, while in C. Amomutn the epidermis is perfectly smooth 

 and the color of the under side usually green. Other characters of 

 C. Pnrpusi are the generally narrower leaves, cuneate at the base and 

 with only 4 to 5 or rarely 6 pairs of veins usually furnished wnth pale 

 pubescence, the smaller flowers and inflorescence and its more 

 a])pressed pubescence, the paler color of the branches, the but 

 slightly ribbed stone and the usually much paler often almost whitish 

 fruit. The habit of the shrub is looser and especially the moKe or 

 less pendulous leaves give it a distinct appearance from C. Amomum 

 which has broa ler leaves with 4 to 8 pairs of veins and a usually 

 rounded base and stouter petioles. Cornus Purpusi ranges from 



' Gartenfl. 48:338 (1899) ; Mitt. Deutsch. Dendr. (les. 12:48 (1903); Rehder 

 in Sargent's Trees & Shrubs i : 77, pi. 40 (1903).
