DALIBARDA 



Dr. Focke includes this genus in Riibus, making it a subgenus 

 under the same. In this subgenus, he includes R. lasiococcus, R. 

 Fockeamis, R. pedatus and R. Giinnianus. None of these species 

 are related to Dalibarda repens L. The latter differs from all 

 species which have been included in Riihiis, by the practically dry 

 fruit, the essentially monoecious flowers, of which the pistillate 

 ones are apetalous. Dr. Focke describes the flowers as being 

 "both perfect sterile and cleistogamous fruiting." The essentially 

 staminate petaliferous flowers have only rudimentary pistils. The 

 basal apetalous flowers, I think, hardly could be called cleisto- 

 gamous, as I have found no polleniferous anthers, and think that 

 they are pollinated from the staminate petaliferous flowers. This 

 is something which needs further investigation. 



RUBACER 



Dr. Greene* restored the generic name Bossekia Necker for this 

 genus. It is true that Rtibiis odoratiis L. was probably a part of 

 Necker's genus, but Bossekia was not properly published under the 

 American Code. The paragraph concerning the publication of 

 generic names reads as follows: 



"Canon 10. A generic or subgeneric name is published when 

 it has been printed and distributed: (i) with a generic or specific 

 description (or in paleobotany, a figure) and a binomial specific 

 name; (2) with a generic and specific name and the citation of a 

 previously published description ; (3) with a reference to a specific 

 description, which is associable by citation with a previously 

 published binomial species." 



As Necker's Elementa does not contain any specific names, 

 Bossekia could not have been published under proviso No. i or 

 No. 2. It remains to see if it was published under No. 3. Necker
