teeth. Ten feet farther up the hill and where the ground 

 was less wet was another cluster of plants resembling the latter 

 in size and general features but with only a few flattened teeth, 

 one having not more than a dozen, while near the top of the 

 slo[)c and on drier ground were a number of plants showing no 

 flattened teeth whatever. The conclusion would appear to be 

 that growth in wet ground tends to develop flattened teeth. 

 Aside from the flattened character of the teeth these plants would 

 be referred to form /9, which I have never observed growing in 

 very wet places. Form ;-, however, has been observed always 

 in wet springy places and shows no tendency to the flattening 

 of the teeth. 



The various forms of //. repanda have been thus fully dis- 

 cussed in order to point out the great variability of this species 

 and to emphasize the need as well as the opportunity for thorough 

 field-work on the forms, habitat, and distribution of this common 

 yet little understood plant.

THE BOTANICAL MEETING AT McCALL'S FERRY, 

 PENNSYLVANIA 



By George V. Nash 



As announced in the June number of this journal, the joint 

 meeting of the Torrey Botanical Club and the Philadelphia Botan- 

 ical Club took place at McCall's Ferry, the week of Jul)' 2-9. 

 The meeting proved to be a most enjoyable affair, and much of 

 this enjoyment was the result of the care and endeavor on the 

 part of the members of the Philadelphia club, several of whom 

 acted as guides and led us to the haunts of rare and interesting 

 plants. Certainly the event was a memorable one. Friends and 

 members of other botanical societies accepted the joint invitation 

 of the two clubs, and added much to the pleasure of the meeting 

 by their presence.
