duced an immense numbeif' of variWts! Some of these have 

 been thought worthy of varietal names but a host of other and 

 less striking forms have annually been pulled up and thrown 

 away, or given to flower-loving friends. The variety fnbnli- 

 forme, with all-the rays quilled, was produced in a single sea- 

 son by sowing seeds from a flower-head which had a few quilled 

 ray-flowers. Flowers of pure red, bred from the variety riihra, 

 as well as all gradations between this and the form pulcher- 

 rima, are common. A partly double form has also appeared in 

 this season's plants and it is likely that one or two' seasons ex- 

 perimenting will result in double flowers. Most of the varia- 

 tions thus far produced are of interest to the student of evolu- 

 tion only, but some others are worthy of a place in any flower 

 garden. 



An Elementary Species of White Clover. — Many of 

 the elementary species which DeVries has pointed out as exist- 

 ing in practically all botanical species may be found by any- 

 body who will take the trouble to look for them. If you have 

 noticed a plant that differs from the normal, it is likely to be 

 one of these lesser forms which are included m what we ordi- 

 narily call a species. An interesting illustration of this ap- 

 peared in the editor's grounds last spring in a plant of white 

 clover that had added to its color scheme. As everybody knows, 

 the three leaflets of this plant are marked near their bases by 

 an angular whitish blotch. In the variation mentioned this 

 mark has spread over the whole base of the leaf and taken on a 

 tinge of yellow. If the form were worth anything, it would be 

 easy to breed up a race of plants with this characteristic. 



Remedies for Ivy Poisoning. — -With reference to the 

 note in your February number regarding poison ivy dermatitis, 

 I can add Antennaria sp. to the list of alleged remedies. An in- 

 fusion of an unnamed species of this genus I have heard highly 

 recommended for the disease; but I think with you that none 

 of these plants has any real virtue. Ivy poisoning without any
