has escaped from cultivation in several places. It is good for 

 naturalizing along streams and in wet places but the flowers 

 are too small to make them desirable for cutting. It is likely 

 that the plant may be of value for introducing a strain of yel- 

 low into the garden irises. Pure yellow flowers of this kind 

 are still rare. — Ed.] 



Frkak Dqgvvood. — In the spring of 1920, I found a 

 curious flowering dogwood. It was about twelve feet high 

 and very thickly covered with flowers. Instead of the usual 

 four broad bracts around each bunch of florets, however, there 

 were two narrow ones. The whole tree was searched care- 

 fidly for normal bracts and none were to be seen. I never 

 saw so many berries on a dogwood as that tree displayed, in 

 the fall. In January the tree was visited again and I was not 

 surprised to find only small and pointed buds foretelling that 

 it would have nothing but leaves to show next summer. — Nell

Wanted and for Sale. — Dr. W. N. Steil. University 

 of Wisconsin, Madison. Wis., is making a study of the an- 

 therida of some of the scale mosses and desires living speci- 

 mens of Riccardia pinguis, R. uudtifida and P cilia from other 

 localities for study. The Riccardias are tropical and sub- 

 tropical plants belonging to the thallose Jungermanniales. 

 They have a fleshy thallus usually with short lateral branches 

 upon which the sex organs are borne. They grow in swamps 

 and low grounds. Anyone who can collect specimens of these 

 plants should communicate with Dr. Steil. Those who wish 

 specimens of Rocky Mountain plants for their herbarium will 

 be interested in knowing that Mrs. M. E. Soth, Pocatello, 

 Idaho, has specimens for sale. These include a number of 

 alpine specimens.
