(1992.) Q. Garryana, Douglas; Macoun, Cat. III., 440.
Since the publication of Part III., the question has been raised whether E. Brown's Q. Jacobi is a good species or not. In August, 1887, I collected fine specimens of the oak on Sir James Douglas's lawn in Victoria, Vancouver Island, upon which Mr. Brown founded his species. Part of these specimens were submitted to Professor Sargent, and by him referred to Q. Garryana. I had collected specimens of the oak on other parts of the island, and could see no difference between them, so I fully agreed with Prof. Sargent that Mr. Brown's species could not stand.
In March last (1890), Rev. E. L. Greene, Berkeley, Cal., asked me to send him specimens of the Vancouver Island Oak. I did so; and he writes that all the specimens sent are Quercus Jacobi, R. Brown, and quite distinct from the Oregon Q. Garryana. It is therefore probable that the Vancouver Island Oak will become Q. Jacobi, instead of Q. Garryana.
We are still doubtful of the occurrence of this tree within our limits.
(1999.) Q. coccinea, Wang., var. ambigua, Gray, Man., ed. VI., 478.
In the new edition of Gray's Manual this variety is said to extend along the north-eastern borders of Lake Champlain and northward. This being the case, the Nova Scotia, New Brunswick, and most of the Quebec Q. rubra becomes this variety. Collectors in these provinces should collect a good series of fruiting specimens to determine this.
