three inches long as in P. Muhlenhergii. Nor are these always 

 terminal, for the stem is sometimes prolonged or branched near 

 the top in such a way as to leave the flower spikes lateral or 

 axillary. I label the specimens var. longispicatum. 



Polygonum acre H. B. K. 



Sea shore near Amagansett. July. This is a form in which 

 the leaf has a dark colored central spot. 



Polygonum cilinode Mx. 



A small form, variet\^ erectuvi, eight to twelve inches high, 

 was discovered on the top of Bald mountain. Not finding any- 

 thing on which to climb it assumes an erect mode of growth. 

 It is either simple or sparsely branched. Its behavior is in 

 marked contrast to that of the woodbine, Cissus Amjpelopsis, 

 another climbing plant, which, when growing in places where it 

 finds nothing on which to climb, trails over the ground. 



Aplectrum hiemale N^utt. 



This rare plant occurs sparingly near Vaughn's, Washington 

 county. Burnham. 



Habenaria lacera B. Br. 



Border of Avoods. Selkirk. July. This is a peculiar form 

 worthy of designation as var. elongata. Flower spike eight to 

 ten inches long, bracts narrow^, linear-lanceolate, the lower ones 

 much longer than the flowers, segments of the corolla, longer 

 and more slender than usual, the middle segment of the lip 

 linear, scarcely widened at the tip. 



Aletris farinosa L. 

 Abundant on Hempstead Plains in open fields. July. 



Juncus tenuis Wilkl. var. secundus Migelm. 



Riverhead and Amagansett. July. Blue Mountain lake. 

 August. The branches of the panicle are not always incurved, 

 but the secund capsules give to the plant a very distinct appear- 

 ance. Yar. GOiigestus, or its eastern analogue, was collecred at 

 Amagansett.
