Cysto])hyllum sisymbrioides. I liave found, however, a plant 

 which is much more applicable to Cystophyllum (Myagropsis) 

 Turneri than to Cystophyllum sisymbrioides. The detail will be 

 given under the next species. As for llyagropsis Camelina I 

 have little doubt, judging from the descriptions and figures given 

 by KuTZiNG, 1. c, that it belongs to the present species. 



In defining Myagropsis Camelina, Kützing^^ says that the 

 stem is "zusammengedrückt, dreikantig" and that the branchlet 

 ''flach dreikantig." He further observes that the stem is "hie 

 und da mit spitzigen und hakenförmigen Dornen besetzt," and 

 the branchlets "an den Kanten mit zweispalten, entfernt stehen- 

 den, sehr kleinen Dörnchen besetzt." These statements are 

 evidently induced from the scars of the dropped lateral branchlets, 

 leaves, or vesicles. The size of the vesicles cannot be a specific 

 character in this case. I have many specimens of Cystophyllum 

 sisymbrioides which have in their basal portions more roundisli 

 vesicles than Kutzing has figured under Myagropsis Camelina.
