I cannot help thinking that Anderson's genus IHschdstocalyx 

 (misprinted Dktiekomly® in ' Genera Plantarum ') must be con- 

 sidered as a section, though doubtless a very well-marked one, of 

 liuellia. The plant now under notice is different from typical 

 Dischistocalt/x, insomuch as its calyx is divided into three and not 

 four lobes ; but I presume that all species of liuellia with connate 

 calyx-lobes must be referred to § DUchutocalyx, whatever the 

 manner and degree of connation.

CARDAMIXE. PHATEySIS, L., AND ITS SEGREGATES. 



By George Nicholson. 



For the last two or three seasons I have collected a good series 

 oi forms of this very widely distributed aud extremely variable 

 species, and during my attempts to work them out I have for- 

 tunately been able to consult the herbaria at Kew and at the 

 British Museum. As mere descriptions of such critical plants as 

 the Cardamines are often totally inadequate for the proper identi- 

 fication of the segregate forms, comparison with authenticated 

 specimens is at times necessary before any one can be at all 

 certain that he has correctly named a given form. This fact has 

 been strongly impressed on my mind whilst going over the large 

 series of C. prateims, its sub-species, and allied species contained 

 m the above-mentioned herbaria. Widely different plants have 

 received the same name from careful collectors and botanists, 

 wll o, in all probability, have not seen a type specimen of the 

 plant ni question, but have been obliged to content themselves 

 witli simple descriptions. Considering the wide distribution of 



P™tm*it, a great range of variation might reasonably be 



expected, but any one who is only familiar with the species as it 



grows everywhere around us would be surprised at its protean 



character taken as a whole. If half a dozen, or even more, 



i the ^ell-defined varieties were submitted to such a one, and the 



1> l? U ! e(llnte linlis were not forthcoming, these forms would pro- 

 abiv be looked upon as good species, even should the individual 



not belong to the « Jordanic " school. 

 In tlm « y t 



I niat erial at Kew (not perhaps so full as to allow one to express 



very decided opinion in every instance), some of the Chilian 



jiecies founded by Pliilippi are only geographical outlying forms of 



t£7, lei i foimck ' tl b y Thilippi are only geographical outlying forms of 

 Polymorphous V. pratenti*, and some of them are indistinguish-
