ANNOUNCEMENTS OF IMPORTANCE 
TO AU* EXP EfUMENTERS. 
The Office still has United 'stocks of Tqraktogerm fyrzii, the true 
chaulmoogra tree, and Oneoba eehinata, an allied shrub known also to yield 
ehauimoogrie acid. Experimenters in tropical regions who have not yet 
secured these r and who would like to do 90 » can be supplied if their 
requests are received at once. In ail probability, neither of these 
plants will be included in the general distributions next winter. 
Hex paraguarientit, Yerba mate or Paraguay tea, was described in the 
January number of Plant Immigrants. A limited number of young plants 
is etill available for distribution. The meager information at our . 
command leads us to doubt that they can be grown successfully in re- 
gions too cold for the lemon. Experimenters who are desirous of test- 
ing this species should apply at once. 
To Experimenters who have received plants from this Office in past 
years, we desire to point out the value of Reports on the Behavior of 
Former Introductions which appear in Plant Immigrants. 
If any of the plants which have been sent you have flowered or 
fruited; if you have made observations on the amount of cold or drought 
which they will stand; if you have learned things regarding their cul- 
tural requirements or the best methods of propagation, then you should 
share this information with others. For it should be remembered that 
there are probably many people who are growing the same plants which 
have been sent you, and they may be helped and encouraged by your ex- 
periences. Furthermore, these first records concerning the behavior of 
plant introductions may later have real historical value. We urge all 
Experimenters therefore to send to this Office useful or interesting 
information concerning plants which they have under trial.
