dent in the Garden's own herbarium. The speaker insisted upon 

 the urgent need of soon building ample herbaria as, because of 

 the increasing rarity and even disappearance of certain species, 

 it will later be impossible to obtain such data. 



For the obtaining of information concerning our orchid-life 

 Dr. Denslow suggested: (a) more state and other local floras 

 (studies to give status of orchids and other plants in the same 

 waning condition), (b) exploration, (c) increase of our her- 

 barium, and toward this he advocated a system of exchanges. 

 For the recording of our information as to species-ranges, and 

 our help in realizing where exploration is most needed, he advo- 

 cated plotting known areas of occurrence upon blank outline 

 maps. 



Dr. Denslow closed with the injunction that in the next ten or 

 fifteen years we must discover whatever we wish to know con- 

 cerning the occurrence or many native orchids — therefore " be 

 up and doing ! " 



Dr. Alfred Gundersen showed and discussed ''Labels and 

 Records for Herbaceous Plants." The Brooklyn Botanic Gar- 

 den has had difficulty with the wanton transference or removal 

 of labels from the beds for herbaceous plants. The resulting 

 confusing of data was first obviated by the mapping of their 

 plantings ; still for the public who had to depend upon the label- 

 ing present, this was not sufficient. Finally, after a series of 

 experiments, there has been adopted a metal two-faced label, 

 firmly secured to a post and so placed between two plantings on 

 each side that each wing of the label and each face of each wing 

 will designate a planting, the whole labeling four plantings. The 

 oermanence and obvious economy of such a label should lead to 

 its wide adoption. 



The meeting adjourned.
