40 The Ottawa Naturalist. [May 



I am unable to think of it as representing the same species. The 

 fruits of this fragment are immature. 



Since Port Huron, whence this new variety comes, is only 

 separated from Ontario by the St. Clair River, it becomes 

 extremely probable that this plant will be found also on the 

 Ontario side; so that it ought to be here inserted at least pro- 

 visionally as a Canadian type. 



Thalictrum dioicum, var. Langpordii. Stem 2 feet high, 

 marked for 6 or 8 inches up to the first and sometimes the only 

 well developed leaf; leaflets much smaller than in the type, 

 seldom subcordate or even subtruncate at base, and more inclined 

 to flabelliform, their lobes somewhat less obtuse: filaments short, 

 purplish; anthers also not long as in other forms, somewhat 

 uncinate-mucronate: achenes long and narrow, obliquely oblong, 

 fully 5 mm. long, their 10 ribs not very thick, closely approxi- 

 mate, more or less wavy. 



Vanorder's Grove near Kingston, Ont., T. E. Langford, 

 1897, the flowering specimens on the 10th, the fruiting on the 

 25th of May. Tvpe specimen in Herb. Field Museum, Chicago, 

 sheets 83,939 and 83,940. 



While the foliage of this beautiful form does not so widely 

 differ from that of ordinary T. dioicum, the carpels, with their 

 irregular outline and undulating rather thin ribs, might well 

 be thought to mark a species. The same is in Herb. Field Mus., 

 sheet 190,985, from Hamilton, Massachusetts, by the late Thos. 

 Morong, in 1875, the flowers in May, fruit in June; the waviness 

 of the ribs less pronounced. 



THE FLETCHER MEMORIAL FUND. 



Since the appearance of the note in our April issue, a fur- 

 ther number of subscriptions have been received from members 

 of the Club and friends of the late Dr. Fletcher. There must 

 still, however, be many members who are desirous of contribut- 

 ing something to the above fund, and it would help the work of 

 the Committee very much if they would intimate the amount 

 of their subscription, at an early date, to the Secretary-Treas- 

 urer, Mr. Arthur Gibson, Central Experimental Farm.
