correctly) to be abundant near Romsey, and to be known in 
Cornwall.

Tue plants known in cultivation under the names of Abies Hook- 
eriana and Abies Pattoniana have long been a source of great con- 
fusion and perplexity both to botanists and horticulturists; and 
the conflicting opinions of authors find expression in the most 
marked way in the recent ‘Manual of Conifere,’ published by 
Messrs. Veitch, where in page 117 of that work it is stated that 
*there are two hortieulturally distinct forms in cultivation," 
although “ botanically the two trees are considered to be but one 
species.” 
The two forms have been in cultivation in the Royal Botanic 
Garden, Edinburgh, since their first introduction ; and, with the 
aid of a copious series of specimens, chiefiy supplied by my late 
father, Mr. James M*Nab, and raised from seed by himself in the 
Edinburgh Garden, I believe Iam in a position to give a cor- 
rected history ofthe two forms. That the forms are distinct 
microscopically, I have already pointed out in my paper in the 
* Proceedings of the Royal Irish Academy, vol. ii. 1875, p. 209, 
and have given figures of the sections of the leaves. Although 
the leaves of both have been examined, I have only succeeded in 
getting the cone of one of the forms. In the paper just referred 
to I stated that the cones of the two were exceedingly close; but
