VOLUME 7 Part 8 NORTH AMERICAN FLORA (UREDINALES) AECIDIACEAE (continuatio) JOSEPH CHARLES ARTHUR MICROPUCCINIA (conclusio) JosEPH CHARLES ARTHUR AND HERBERT SPENCER JACKSON PUBLISHED BY THE NEW YORK BOTANICAL GARDEN DECEMBER 20, 1922 ANNOUNCEMENT NortH AMERICAN FLorA is designed to present in one work de- scriptions of all plants growing, independent of cultivation, in North America, here taken to include Greenland, Central America, the Republic of Panama, and the West Indies, except Trinidad, Tobago, and Curacao and other islands off the north coast of Venezuela, whose flora is essentially South American. The work will be published in parts at irregular intervals, by the New York Botanical Garden, through the aid of the income of the David Lydig Fund bequeathed by Charles P. Daly. It is planned to issue parts as rapidly as they can be prepared, the ex- tent of the work making it possible to commence publication at any number of points. The completed work will form a series of volumes with the following sequence : Volume 1. Myxomycetes, Schizophyta. Volumes 2 to 10. Fungi. Volumes 11 to 13. Algae. Volumes 14 and 15. Bryophyta. Volume 16. Pteridophyta and Gymnospermae. Volumes 17 to 19. Monocotyledones. Volumes 20 to 34. Dicotyledones. The preparation of the work has been referred by the Scientific Direc- tors of the Garden to a committee consisting of Dr. N. Ll. Britton, Dr. W. A. Morrill, and Dr. J. H. Barnhart. Professor John M. Coulter, of the University of Chicago; Mr. Frederick V. Coville, of the United States Department of Agriculture; and Professor William Trelease, of the University of Illinois, have consented to act as an advisory committee. Each author will be wholly responsible for his own contributions, being restricted only by the general style adopted for the work, which must vary somewhat in the treatment of diverse groups. The subscription price is fixed at $1.50 for each part; it is expected that four or five parts will be required for each volume. A limited number of separate parts will be sold at $2.00 each.

Pycnia rare, on certain hosts only, amphigenous, crowded in small groups or scattered among the telia, punctiform, yellowish, inconspicuous, globoid, 100-150 u in diameter; ostiolar filaments 50-80 » long, becoming agglutinate. III. Telia amphigenous or caulicolous, solitary or more commonly gregarious and often more or less confluent in orbicular groups 0.2-1 cm. across, on discolored spots, variable in size, 0.2-1 mm. in diameter, round or elliptic, usually early naked, compact, at first punctate, often becoming pulvinate, dark chocolate-brown or blackish, ruptured epidermis usually conspicuous; teliospores ellipsoid, oblong, or obovate, occasionally irregular, 18-28 by 35-64 u, rounded, obtuse or acute above, rounded or occasionally narrowed to pedicel below, usually noticeably constricted at septum; wall dark cinnamon- or chestnut-brown, 1.5-3 » thick, usually greatly thickened above, concolorous or sometimes paler, 4-15 wu, smooth; pedicel colorless or golden-brown, firm, ouce to thrice length of spore; mesospores and spores with three or more cells occasionally intermixed. On some hosts, especially when accompanied by pycnia, with a-few detached peridial cells and aeciospores within the telia, best seen in young sori; peridial cells colorless, globoid, 24-36 by 26-48 yu, closely and coarsely tuberculate; aeciospores globoid, 16-26 by 20-32 n; wall golden-brown, 1.5—3 » thick, finely verrucose. This species is correlated with Dicaeoma Stipae (Arth.) Kuntze, the telial characters of the two species being essentially the same and the hosts of the short-cycled species cor- responding to the aecial hosts of the heteroecious species. This agreement doubtless indicates a common origin for the two species. On CARDUACEAE: . Chrysoma laricifolia (A. Gray) Greene (A plopappus laricifolius A. Gray), Arizona.

The telia bear a close resemblance, as well as do the ure- diniospores and teliospores, to those of Tvanzschelia cohaesa, which is only known on species of Anemone.

DOUBTFUL OR EXCLUDED SPECIES Pucernta BuLLARIA Schw. Trans. Am. Phil. Soc. IT. 4: 296. 1832. (Not P. Bullaria Link, 1825.) This fungus is on Hyssopus nepetoides, and may be the early stage of some ascomycete. PUCCINIA FURFURACEA Ellis & Gall. Incidentally mentioned by Dietel (Hedwigia 37: 202. 1898) as from Mexico; doubtless a hyponym. PUCCINIA INCARCERATA Lév., reported from Cuba, on petioles of Cissus, probably belongs to the Ustilaginaceae, and is usually recorded as Mycosyrinx Cisst (DC.) G. Beck.
