NOTES TO PLANT LIST. 



*i Botrychium ternatimi, (Thunb.) Sw. var. dissectiim. 

 (Botrychium dissectum,) Spreng. 



This plant is by no means rare in this section of New Hampshire. It is com- 

 monly found growing with the other varieties in about the proportion of one to 

 five. The plants are extremely variable in size and also in the fineness of the cut- 

 ting of the lobes in the sterile segment of the leaf. The fertile segment is seldom 

 developed. There are numberless gradations between dissectum and the other 

 typical forms and it is frequently impossible to decide to which named variety 

 certain plants should be referred. The particularly close connection of dissectum 

 with obliquum through intermediate forms militates against the propriety of separ- 

 ating the former as a species. 



*2 Equisetimi palustre, L. 



[See Rhodora, i- 75] 



*3 Chamgecyparis sphaeroidea, Spach. 



The only station yet reported is the " rhododendron swamp " located near the 

 northwest comer of Manchester. 



[ See note on Rhododendron maximum, below.] 



*4 Graniinese. 



All doubtful or ambiguous plants of this order have been submitted to the 

 most competent authorities for examination and classification. In the difficult 

 and as yet unsettled genus Panicum specimens have been verified by Prof. F. L. 

 Scribner, the expert agrostologist of the Department of Agriculture, Washington, 

 D. C. 



*5 Aristida gracilis. Ell. 



Abundant in Pelham along Beaver brook, the plants varying greatly in size 

 and form, some being single and slender, others rather densely tufted and quite 

 stout. 



♦6 Sporobolus neglectus, Nash. 



Common at least as far north as Concord, where there occurs a form more 

 robust than usual, mostly purplish, and with spikelets approaching those of S. 

 asper.
