ent, the tree is so abundant, April 10-20 ; 

 prefers hilly districts. 



Crataegus crus-galli, Cock-spur Thorn. — 

 This was the only species of this genus 

 that I analyzed (but C. coccinea must have 

 escaped rue) ; this was rather common 

 about streams, at base of mountain, May 

 15. 



(Pyrus arbutifolia, Choke-beny. — Also 

 escaped me, although it ought to be at 

 least very common.) 



(Rosa lucida, Dwarf Wild Rose; Rosa 

 Carolina, Swamp Rose; Rosa rubiginosa, 

 Sweet Brier; all these should be called not 

 rare, at least during June. I am sure I 

 collected them all. The falling of the pe- 

 tals prevented me from absolutely identify- 

 ing them.) 



Rubus adoratus, Mulberry, Bramble, or 

 Flowering Raspberry. — Common in the 

 mountain siopes and wood-ronds; late in 

 May and early June. 



Rubus triflorus, Dwarf Raspberry. — 

 Found in woods, high and low, dry or 

 moist places; rather common, early in June, 

 a small erect plant. 



Rubus strigosus, Wild Red Raspberry. — 

 Common in fields at foot of mountains, in 

 June. 



Rubus occidentalis, Black Raspberry, 

 Thimble-berry. — Abundant along road- 

 sides and in fields by fences ; last of May 

 and first of June. 



Rubus villosus, Common High-bush 

 Blackberry.— Abundant along with occiden- 

 talis. 



Rubus canadensis, Low Dewberry Black- 

 berry. — Rocky fields; common last of May. 



Ruuus hispidus, Swamp Blackberry. —
