Fagus syl vatica, Beech — Rather rare as 

 far as I can judge from what I have seen 

 May. 



Corylus americana. Hazelnut. Not rare, 

 (apparently rather rare here) in this part of 

 the State, flowers last of April. 



(Ostrya virginica. Hop norubeam, Iron- 

 wood ; Carpinus americana. Hornbeam, 

 Water Beech ; ought both to be found not 

 rare, flowers last of April). 



Betula papyracea. Canoe or Paper Birch 

 — Common. Last of April (B, populifolia, 

 White Beech, I think I detected on the 

 mountains where it ought to be rather com- 

 mon). 



Betula lenta. Black Birch. — Common in 

 damp places by water usually. Last of 

 April. (I think other species occur, but I 

 did not find them in my short time collec- 

 ting.) 



Alnus serrulata. Common Alder. — Abun- 

 dant by streams and roadsides. April. 



(Alnus incana, Black or Speckled Alder, 

 and Alnus virdis. Mountain Alder. — I am 

 sure I gathered, and found chem not rare 

 in April). 



Ciunptonia asplenifolia, Sweet Fern. — 

 Common in woodland clearings. Early 

 May. 



(The Willows Salix, and Poplars, Popu- 

 lus. were not studied at all. owing to the 

 difficulty of separating them, without the 

 fruit which does not appear until the suc- 

 ceeding season). 



(The Coni ferae or Pine family were not 

 studied in the short time allowc^for cob 

 lecting). 



Arissema triphyllum, Jack-in-the-pulpit.
