Excerpt from Revision of the North American Liliaceæ, And, Descriptions of Some New Species of North American Plants

The subdivision into tribes is here based upon the characters of the inflorescence, and such others as can be used Without separating evi dently allied genera, to avoid Which it is sometimes found necessary to lay little stress either upon the degree of union of the segments of the perianth or upon root-characters. The grade of the tribes is equalized so far as possible by reducing the less positively marked groups to the rank of subtribes, though some isolated genera are still left, Which refused to be so degraded. As respects the citation of authorities under the specific descriptions, only the more important synonyms and figures are usually referred to. Much indebtedness is acknowledged to the recent revisions of various portions of the order by Mr. J Gr. Baker of Kew, although his conclusions are not in every case adopted It is a source of regret that his last paper upon the Oolclzicacece has not yet been issued, and that the present article, Which has been delayed for some time With the hope of benefiting by it, must be completed Without such assistance.
