As the two parent species cannot be separated by strong morphological 

 characters it is even more difficult to point out good characters to dis- 

 tinguish the hybrid; the differences become really apparent only by com- 

 parison with living plants of the two parent species. From T. boccata L. 

 the hybrid may be distinguished by the darker olive-green, often slightly 

 reddish color of the branchlets, not light or yellowish green as in that 

 species, by the keeled scales of the winter-buds, by the stouter and broader, 

 more abruptly acuminate leaves with a more prominent midrib above and 

 by the abrupt enlargement of the leaf-cushion into the petiole. From 

 T. cuspidata it differs chiefly in the olive-green color of the branchlets, 

 not brown the second season as in that species, at least on the more 

 vigorous branchlets, in the obtuse winter-buds with obtuse scales, in the 

 leaves spreading distinctly in two ranks and rather lustrous above. This 

 hybrid was raised by Mr. T. D. Hatfield about 20 years ago together with 

 other forms between different varieties of the parent species which com- 

 bine the characters of the parents in various degrees. An illustrated 

 article giving a record of his observations was published in 1921 by Mr. 

 Hatfield in vol. xxxm. of the Garden Magazine (pp. 23-26). One of 

 the forms seems worthy of a distinct name and may be called: 



Taxus media f. Hatfieldii, forma nova. 



Compact shrub of conical outline with upright and ascending branches; 

 winter-buds acutish, with obtuse to acutish slightly keeled scales; leaves 

 radially arranged, straight, 1.5-2.5 cm. long and about 3 mm. broad, 

 rather abruptly pointed, somewhat lustrous above and with a prominent 

 midrib; petiole abruptly enlarged into the leaf-cushion.

 D. Hal field, March 18, 1923 (from plant figured by T. D. Hatfield in Garden Mac. 

 xxxm. 25 as "Irish Yew"). 



This form, which is probably a hybrid between T. cuspidata and the 



Irish Yew, T. baccata var. fastigiata Loud., is particularly valuable for 



its formal habit and may take, together with the following form, the place 



of the Irish Yew which is not hardy in the neighborhood of Boston while 



the forms of T. media are perfectly hardy here and probably even farther 

 north. 



Taxus media f. Hicksii, comb, no v. 



T. cuspidata Hicksii Hort. 

 Shrub with upright and ascending branches forming a columnar bush ; 

 winter-buds oblong-conic with obtuse slightly keeled scales; leaves mostly
