type of hybrid of blrunis and f/nuu/i flora that lias proved 

 not uncommon in my cultures. The description of these 

 two plants will now follow, arranged to bring out the sal- 

 ient features in comparison with the parent species and 

 with Lamarckiana. 



Hybrid 10.30 La. 1. Bosette.— The mature rosette 

 (Fig. 9), about 3.3 dm. broad, was persistent. Older
