30 Report of the State Botanist. 



Scirpus sylvaticus L. var. digynus Boeckl. 



This sedge is apparently more common than has been supposed. 

 Fine specimens were obtained near Wilton, Saratoga county. It 

 maintains its distinguishing characters with great uniformity 

 and is apparently a good and distinct species, easily recognizable 

 at a glance and at once distinguishable from S. sylvaticus by its 

 more densely clustered darker colored spikelets and by the 

 purplish red sheaths that give a variegated appearance to the 

 stem. 



Scirpus polyphyllus Vahl. var. macrostachyus Boeckl. 



Lake I'leasaut. August. This variety is not indicated in the 

 Manual. It differs from the ordinary form of the species as 

 represented in our flora, in being le^s leafy, in having much 

 longer and darker colored spikelets, shorter achenes and longer, 

 more slender and more sparsely and irregular barbed bristles. 

 In general appearance it is quite unlike the leafy form with 

 short-ovate, densely clustered yellow-brown spikelets. Occasion- 

 ally a slender pedical supporting a cluster of spikelets rises from 

 the axil of the u]jpermost leaf. 



Eriophorum cyperinum L. var. laxum W. d; C. 



This variety was found at Lake Pleasant growing, in several 

 instances, side by side with the typical form of the species. In 

 addition to the distinguishing characters mentioned in the 

 Manual it was found that when growing side by side and, so far 

 as could be seen, subjected to exactly the same conditions, the 

 variety reached maturity much earlier than the type. The 

 woolly bristles of the mature plant are much paler and less 

 dense in the mass. Sometimes the spikelets are all contracted 

 into a single dense cluster one to two inches in diameter. 



Carex flava 'i. var. graminis Bailey. 

 Borders of lakes. Adirondack mountains. July. In our 

 specimens the perigynia often have the beak deflexed as in the 

 type, but in other respects the agreement with the description is 

 good. 



Carex granularis Muhl. var. Haleana Porter. 



Swamp near Meadowdale. June. 



Carex alopecoidea Thckm. 

 Plentiful about Lyons, Wayne county. June.
