ture upon fungi, his work stands out with conspicuous individual- 

 ity. That he has apparently described, in some cases, species 

 already described by older mycologists of Europe is no reflection 

 upon his remarkable ability in the discernment of specific and 

 generic characters of our native species. 



His work will stand for all time as the foundation upon which 

 later students of fungi may build with safety a more elaborate 

 morphological and systematic revision of the fleshy and woody 

 groups of fungi. 



Those friends, admirers and fellow botanists who have con- 

 tributed toward bringing into existence this testimonial exhibit 

 of mushroom models may feel that there is no more suitable 

 memorial possible. There are few pages of modern literature 

 dealing with the fleshy and woody fungi that do not reflect in 

 some degree the individuality of Doctor Peck's work, and looking 

 at these models in the State Museum, with their exquisite 

 variety of form and color, one may imagine with what pleasure 

 and appreciation they would be viewed by him whom they 

 memorialize. 



THE WEIGHT OF SEEDS AS RELATED TO THEIR 

 NUMBER AND POSITION 



By J. Arthur Harris 



Professor Halsted's interesting paper under the above title 

 in the June, 1917, number of Torreya is well worthy of the 

 consideration of those who, as he suggests, have the opportunity 

 of investigating the internal factors influencing seed number 

 and seed weight. Our knowledge of the physiology of seed pro- 

 duction is very limited indeed. Much of the work which has 

 been done has been based upon such small series of material 

 that the conclusions are of little real value. 



The question of the relationship between number of ovules 

 formed, number of seeds developing, and position of seed in the 

 pod in the garden hesin*Phaseolus vulgaris, has received very 

 detailed consideration.
