L. SPICATA Lamarck, Diet. Bot. Ill: 587. 1789. This lis a species with at least five well-defined phases, which may be dis- tinguished as follows: a) Var. leptostachys (A. DeCandoUe) Mackenzie & Bush, Fl. Jackson County, Mo. 183. 1902.—Type Locality: "in Carolina ; Type Specimen: The plant described by DeCandolle as L. leptostachys was seen by him in the herbarium of Asa Gray, col- lected by Fraser. This has not been seen, but there is in the New York Botanical Garden a specimen collected at Lincolnton, N. C, by the Rev. M. A. Curtis, which was verified by Asa Gray, and is also marked " Loh. lepto- stachys Geneve ;—L. leptostachys A. DeCandolle, Prodr. Syst. Veg. VII: 376. 1839. L. bracteata Small, Fl. 1146. 1903.—Stem strict, unbranched, 30- 120 cm. high, dark pur- plish-red and densely short-pubescent near the base, becoming smooth and light green above; often pubescent on the angles formed below the decurrent leaf-bases. Cauline leaves 10-40, usually quite close together and somewhat appressed to the stem, thus giving them an imbricated appearance in dried material; firm or leathery in texture; sessile, or the lowest narrowed to short petioles; the lower and middle ones obtuse, long-oblong or oblanceolate, to X 12 cm., appearing sub-entire, but beset with callose-glandular teeth along the margins. Upper leaves gradually smaller, becoming definitely bract- like (lance-acute), and merging into the bracts of the inflorescence. Basal leav
