times associated with no. i6, but then usually sparse. (This may 

 be the fresh stage of our no. 14.)

Specimens from the vicinity of Albany (Mr Gillett) and the 



Indian Ladder, Helderberg mountains (Mr Burnham). N.Y.

Schweinitz '34, no. 2805 Pa. 



Persoon's description of E . p 1 a t a n o i d e u m , given as a 

 doubtful synonym under his no. 24, E . g r i s e u m , agrees well 

 with the preceding, and it seems likely that Schweinitz had that 

 form in hand. 



*I4 A rusty or brown erineum on the under side of the leaf 

 forming patches along veins. Trichomes capitate, sessile. 



Garman '92, no. 7 111., Ky. 



Except for the described position " along veins " this appears to 

 be the older stage of no. 12, above. Specimens in the State Her- 

 barium agreeing with the latter have taken on the color of this, some 

 nearly black; they are from Fort Edward, [sec Peck 1869, 22d 

 Rep't, p.ioi, Erineum luteolum], and Indian Lake (Pro- 

 fessor Peck) labeled Erineum luteolum. N.Y. 



15 An erineum on the ribs rather elongated. 



Hagen '85, no. 24 Western States, Mass. 



This should be compared with our no. 6. 



*i6 A crimson red, purplish or livid erineum in patches on the 

 upper side of the leaf, sometimes sprinkled thinly on the under 

 side also. Trichomes capitate, very short. Apparently whitish when 

 young.

Schweinitz locates E . r o s e u m on B e t u 1 a nigra, see 

 beyond ; this is likely to be his E . p u r p u r a s c e n s , however ;

Specimens from the vicinity of Albany (Mr Gillett), Indian 

 Ladder, the Helderbergs (Mr Burnham) and remarkably fine ones 

 from Spruce creek at 2250 feet, near Kaaterskill falls. In the 

 State Herbarium from Sand Lake and Garrison (Professor Peck)
