Description. A middle-sized or large tree, branching from near the base and 

 forming a compact head: trunk three feet thick, more or less, clothed with a rather thick 

 fissured gray bark: branchlets short, stout, very leafy, tomentose pubescent: leaves broadly 

 obovate ; veinlets only gradually divergent from the midrib and directing the lobes some- 

 what digitately toward the apex of the leaf, which is broadest far above the middle: acorns 

 ovate, less than an inch long, well inserted into a hemispherical scaly cup. 



Habitat. Islands in Puget's Sound, and on the adjacent mainland; also northward 

 some distance beyond the British boundary; apparently often associated with Q. Garryana, 

 its near relative with which authors have generally confounded it. Specimens collected 

 near Steilacoom, Washington, in May, 1888, by Mr. C. V. Piper, and by him distributed 

 as "<2- Garryana^\ though in young leaf and flower only, are of this species according to the 

 venation, though not of the most pronounced type. A specimen from Cedar Hill, Van- 

 couver Island, communicated to me by Mr. Macoun has a leaf much broader and more 

 rounded than in the type, and cleft as it were into three main lobes, of each of which lobes 

 the venation is of that almost palmate character which marks Q. Jacobi as distinct from Q. 

 Garryana. The branch and separate leaf herein figured are from a new locality, on 

 Lopez Island in Puget Sound. These were obtained at the instance of Dr. George 

 Davidson, by his colleague on the Coast Survey, Capt. J. J. Gilbert. The peculiar veining 

 and cut of the leaf are more pronounced in these specimens than they are in one which 

 Mr. Macoun has sent me from the original tree on the grounds of Sir James Douglas 

 upon which Mr. Brown based his species. 



The Fraser River oak is described as being a mere shrub, and, having been referred to 

 Q. Garryana by inference (no botanist having seen specimens), is more likely to be Q. 

 Jacobi.
