One of the most alarming phases of the situation is the escape 

 of the common barberry from cultivation through the dissemina- 

 tion of seeds by birds and through other agencies. Such 

 escaped barberr>^ has been found along streams, in wooded areas, 

 fence rows, etc., and presents one of the most difficult problems 

 of the campaign. Chemical means of killing the bushes have 

 been found effective in preventing sprouts from broken roots 

 from reproducing the shrubs. 



The campaign involves a vast amount of work since the in- 

 spectors must examine all plantings of shrubbery as well as 

 wooded areas to make sure some bush does not go unnoticed 

 and in after years serve as a centre for spread of stem rust and 

 of barberry seeds which in turn will produce more bushes to 

 spread the rust. 



The second paper was by Dr. Alfred Gundersen on "The 

 Systematic Position of the Caryophyllaceae and the Frankeni- 

 aceae." The author's abstract follows: 



The little group of salt-loving plants, the Frankeniaceae, 

 appears to be a link connecting the Caryophyllaceae and related 

 families with the great group of flowers which have chiefly 

 parietal placentation. 



The genus name Frankenia was given by Linnaeus. In the 

 Fragmenta Methodis Naturalis he places it in Caryophyllei. 

 Jussieu places it among "genera Caryophylleis affinia." St. 

 Hilaire in 1824 established the family Frankeniaceae, placed by 

 De Candolle before the Caryophyllaceae, an arrangement kept 

 up by Bentham and Hooker. But in the Eichler and the 

 Engler systems these families are far separated. 



The Frankeniaceae are mostly small tufted shrubs, a few 

 herbaceous plants. The Caryophyllaceae have often a similar 

 appearance, only a few being woody. The leaves of both families 

 are opposite, narrow and entire, in the Frankeniaceae often with 

 rolled edge. The slightly swollen node and stipular sheath are 

 very similar in the two families. The inflorescence in both cases 

 is a cyme, with regular flowers. The calyx of the Frankeniaceae 

 is gamosepalous, like the Dianthus group of the Caryophyllaceae. 

 The ridges of the calyx suggest Plumbago. The ligule of the 

 petals is a remarkable character common to these families. The 

 pistil is one-celled, of several carpels. In the Frankenias the 

 placentation is parietal, with ovules at the lower end only. In
