ANNOUNCEMENT

NortH AMERICAN Frora 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. L. Britton, Dr. W. A.
Murtill, 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. Address:

Puccinia tumamocensis Arth. Bull. Torrey Club 42: 589. 1915.

O. Pyenia hypophyllous, in small groups, surrounded by the telia, honey-yellow, globose,
130-190 » in diameter, deep-seated; ostiolar filaments short, 30-40 u long.

III. Telia hypophylious, closely associated in elliptic groups 3-10 mm. long, surrounding
the pycnia, often confluent, elliptic, 1-2 mm. long, becoming naked by the rupture of the
epidermis which remains attached in shreds, pulverulent, blackish, prominent; teliospores
broadly ellipsoid, 32-42 by 48-61 u, rounded at both ends, slightly constricted at septum; wall
3-5 w thick, dark chestnut- or blackish-brown, sparsely and very conspicuously and irregularly
tuberculate, the pore of lower cell midway between pedicel and septum; pedicel colorless,
fragile, short.

This species is correlated with Dicacoma nodosum (Ellis & Hark.) Kuntze and Allodus
Carnegiana (Arth.) Orton. The morphological characters of like stages in the three species
are similar or identical and together with the correspondence in hosts doubtless indicate a
common origin.

III. Telia chiefly hypophyllous, scattered or sometimes grouped, oval or oblong, 0.5-2
mm. wide by 1-5 mm. long, tardily naked; dark cinnamon-brown, slightly pulverulent, rup-

in size and shape, rounded at both ends, moderately constricted at septum; wall light cin-
namon-brown, about 2 » thick, uniform, finely and inconspicuously striate with longitudinal
rows of minute papillae; pedicel colorless, delicate, about length of spore.

This species is correlated with Dicaeoma Pattersonianum (Arth.) Arth. & Fromme, The
telia of the two species possess common morphological characters, while the host of this species
is doubtless the same or closely related to the probable aecial host of D. Paitersonianum,
the latter having been located with much certainty but not proven by cultures.

This species is correlated with Dicacoma rubellum (Pers.) Arth. & Fromme, the telial

a common origin for the two species.

ruptured epidermis inconspictious; teliospores ellipsoid, 23-26 by 32-40», rounded at both
ends, slightly constricted at septum, the two cells readily falling apart by splitting of septum;
wall golden- or chestnut-brown, thick, 2-3.5 4, with a pale subcuticular layer extending through
the septum, best seen in lactic acid, sometimes slightly thickened at apex, 5-6», smooth;
pedicel colorless, up to three times length of spore.

This species is correlated with Dicacoma Eurotiae (Ellis & Ev.) Arth., the telial characters
of the two species being essentially the same, notably in the unique manner of cell-disjunction,
as well as the host of the short-cycled form being the same as the aecial host of the heteroecious

O. Pycnia chiefly epiphyllous, loosely grouped on discolored spots, punctiform, noticeable,
angularly globoid, 65-115 » in diameter; ostiolar filaments about 35 yu long.

IIl. Telia chiefly hypophyllous, irregularly grouped on pale spots 4-6 mm. across, round

over the pores into a colorless papilla, 5-64, rather inconspicuously verrucose, the pore of
upper cell apical, of lower cell depressed two-thirds; pedicel colorless, fragile.

This species is correlated with Allodus claytoniata (Schw.) Arth., the telial characters of
the two species being essentially alike, and the family of the known host of the short-cycled

This species is correlated with Dicaeoma monoicum (Peck) Arth. & Fromme and Allodus
consimilis (Ellis & Ev.) Orton, the morphological characters of like stages in the three species
being similar or identical, and the hosts of the aecial stage of the heteroecious species cor-
responding with the hosts of the two autoecious species. This agreement doubtless indicates
a common origin for the three species.

III. Telia hypophyllous and petiolicolous, crowded in groups 2-6 mm. in diameter oppo-
site reddish spots, ofteh causing distention of leaf in infected areas, round or oblong, large,
0.5-3 mm. long, rather early naked, pulvinate, brownish-black, ruptured epidermis conspicu-

towed below, constricted at septum; wall chestnut-brown above, lighter below, 1.5—2 » thick,
thickened at apex, 5-12 4, smooth; pedicel colorless, up to twice length of spore.

This species is correlated with Dicaeoma Grossulariae (Schum.) Kern, the telial characters
of the two species being similar or identical, and the host of the short-cycled form corre-
sponding with the aecial hosts of the heteroecious form. This agreement doubtless indicates
a common origin for the two species.
