c/3 ' / H - 61. Note from Dr. Engelmann. — I have now had Prof. Wood’s specimen 
of Opuntia from Westchester Co., one from New Jersey sent by Mr. 
r~rr~c^; < k Meehan, and a third from New England, probably Massachusetts, 
7 . furnished by Prof. Gray, side by side in cultivation with our Missouri 
JJ . y , . and Illinois 0. Rafi-'esquii. It is certainly less spiny, and sometimes 
/ "7 the flower is smaller than in our <plant, but the deep green colour, 
Z j the long spreading leaves, and the bright brown bristles, especially 
Z tyt ^ w 7/ on the older joints, on which they increase in number and length 
to considerable bunches, are characteristic of the plant. With them 
I have growing the true 0. vulgaris sent by Dr. Schott from the 
banks of the Potomac and probably not found north of Chesapeake 
Bay, with thicker light green joints, shorter, thicker, more adpressed 
leaves, and small bunches of short thin greenish yellow bristles. 
This is the plant which is cultivated in Europe under that name 
and has become naturalized in Northern Italy and which I have 
described and hgured as such in Vol. 4, Pacif. R. Reports.
