ZAUSCHNERIA 



Zauschneria, In the American Journal of Botany Vol. 16 pp. 58-68 

 Martha HOend publishes a carefully prepared monograph of this genus. 

 The only criticism I would make on it is that her conception of species 

 is not the correct one. The result is that she recognizes four species 

 where there seems to be but one. I have grown the California form com- 

 mon in the mountains of southern California, and the form which grows 

 m Utah, in my garden for years. The variations that appear in the plants 

 as they grow are entirely too wide for recognition of any but one species. 

 She freely admits intergrading of all the species known to her, but in 

 spite of that fact she upholds four speciea This is not the traditional 

 conception of species. 



It goes without saying that ever>'one has a right to publish an>lhing 

 he see3 fit, the same right others have to criticise whatever is publsihed. 

 ;iut there are certam things which long observation in the field show to 

 r<; true and if there is anything established it is in the main species arc 

 |vc,lGefined in_nature. A few species and a few genera are in a state of 

 i.u.v. Iti addition there is more or less hybridizing in related species and 

 ^^m, genera. But the fact of tlie status of a species is determined bv 

 t.'.;sm-at.on. But \yhen there is constant gradation between so-called 

 i'i>ecie.., the conclusion is obvious that they axe not good species, and any 

 .her conclusion leads to. chaos. The person who follows such a course
