fifteen years, and the practice of thus keeping the pollen from 

 one year to another has been adopted by some of the date-growers 

 in southern California and Arizona. During a recent residence 

 in California, Dr. Stout found that in nutrient media freshly 

 gathered pollen germinated very freely but could secure no 

 germinations with samples of one-year-old pollen. Pollen col- 

 lected in F'ebruary showed some germinations as late as Aj^ril 28. 

 Dr. Stout's paper will be published in the Journal of The New 

 York Botanical Garden. 



The second paper of the program was by Dr. H. A. Gleason 

 on "A Virgin Hardwood Forest in Northern Michigan." Dr. 

 Gleason gave a general account of the composition of the beech- 

 maple forest of that region. Besides beech and sugar maple, the 

 forest also has a small proportion of hemlock, yellow birch, 

 basswood, and elm. The ground vegetation, which must be 

 adapted to life in the dim light prevailing beneath the dense 

 forest canopy, consists chiefly of seedlings of these trees, with a 

 hundred or more herbaceous plants and shrubs. A detailed 

 account of the structure of this forest association will be pub- 

 lished elsewhere. 



Mrs. N. L. Britton exhibited a remarkable fasciated stem of 

 Ailanthns and some leaves of the laurel, Kalmia latifolia, brought 

 in by Mrs. George C. Wheeler from a northwestern part of 

 Manhattan Island, where the shrub apparently still persists in 

 a natural state. 



Dr. A. L. Gundersen spoke of noting on young Phellodeyidron 

 trees in the Brooklyn Botanic Garden leaves in alternate whorls 

 of three instead of the usual opposite arrangement.
