in the lower scales of the winter-buds being broader and stouter, not ovate- 

 lanceolate or even lanceolate and acuminate as in T. canadensis, in the 

 stouter and thicker, broader and longer leaves, up to 2.5 or even 3 cm. 

 long and usually 2 mm. broad, with the green margin on the underside 

 much narrower than the stomatic band, in T. canadensis only slightly nar- 

 rower than the stomatic band, and in the more swollen and prominent 

 leaf -base; the leaves spreading more or less upward and forming a more or 

 less well defined V-shaped depression on the upper side of the branchlets. 

 From T. cuspidata Sieb. & Zucc. it differs in its slenderer branchlets 

 scarcely lustrous and green or greenish during the first winter, in the nar- 

 rower scales of the winter-buds, in T. cuspidata generally ovate and the 

 lower ones triangular-ovate, in the slenderer and thinner leaves, scarcely 



exceeding 2 mm. in width, with the green margin of the under side broader, 

 in T. cuspidata only about half as broad as the stomatic band ; the leaves 

 being usually more or less directed forward not spreading at nearly right 

 angles, and forming a less clearly defined V-shaped depression above. 



Plants and specimens examined: plants growing in the Arboretum under 

 no. 17642 (specimens: December 23, 1924 [type]) and under no. 10760 

 (specimens: September 16, and December 21, 1923). 



This interesting addition to the Yews hardy in the climate of Massa- 

 chusetts, was raised on the Hunnewell estate at Wellesley, Massachusetts, 

 by Mr. T. D. Hatfield a number of years ago. The plants are intermediate 

 between the parents not only in the characters given above, but also in the 

 color of the foliage and in general appearance, though they are yet too 

 young to allow an opinion regarding the habit they will finally assume.

Specimens and plants growing in the Arnold Arboretum examined : col- 

 lected on the coast of Maine by H. L. T. Wolcott in 1897 (no. 14860; 

 specimens: December 8, 1924, type); and collected near Rockingham 

 Junction, Maine, by G. P. Douglas in 1911 (no. 14862; specimens: De- 

 cember 8, 1924). 



This Juniper is a very distinct form which apparently belongs to J.
