Genus and species indet., Morelos.

5. Puccinia Dondiae Arth. Bull. Torrey Club 42: 592. 1915. 
II. Uredinia amphigenous, scattered, round, 0.4—0.6 mm. across, early naked, pulverulent, 
cinnamon-brown, ruptured epidermis rather inconspicuous; urediniospores broadly ellipsoid, 
26-29 by 32-39 »; wall cinnamon-brown, 1.5 » thick, closely and finely echinulate, the pores 
8, scattered. 
III. Telia amphigenous, scattered, round, 0.4-0.7 mm. across, early naked, pulverulent, 
blackish-brown, ruptured epidermis rather inconspicuous; teliospores ellipsoid, 32-39 by 
42-51 yp, rounded at both ends, not constricted at septum; wall dark chocolate-brown, uniform 
in thickness, 4-5 yu, closely and coarsely verrucose; pedicel colorless, about as long as spore, 
more or less hygroscopic, swelling in water up to 32 » wide. 
On CHENOPODIACEAE: 
Dondia intermedia (S. Wats.) A. Heller (Suaeda intermedia S. Wats.), California. 
TypPsé Locaniry: San Diego, California, on Dondia intermedia. 
DistRIsuTion: Known only from the type locality. 
6. Puccinia Viornae Arth. Bull. Torrey Club 45: 145. 1918. 
II. Uredinia not seen; urediniospores in the telia, ellipsoid or elliptic-obovoid, 16-19 by 
24-32 w; wall pale golden-brown, thin, 1-1.5 », thicker above, 3-5 uw, closely echinulate, the 
pores indistinct, probably 2-4 and equatorial; paraphyses in the telia, intermixed with the 
spores or surrounding groups of spores, cylindric, clavate or capitate, 7-23 by 47-64», the 
wall nearly colorless to golden-brown, darker above, thin, 1—1.5 «, somewhat thickened above, 
2-7 yb. 
III. Telia caulicolous, scattered, oblong or linear, 1-3.5 mm. long, somewhat tardily 
naked, inclined to be pulverulent, chestnut-brown, ruptured epidermis conspicuous; para- 
physes few, doubtless of uredinial origin, often wanting; teliospores ellipsoid or oblong, 16-21 
by 29-35 », rounded at both ends, deeply constricted at septum; wall dark cinnamon-brown, 
uniformly 1.5-2 4 thick, moderately and coarsely echinulate-verrucose with conic warts; 
pedicel short, colorless, fragile. 
The collection on which this species was founded also included pycnia and aecia, which 
were described as possibly being a part of the species. Later study makes it more probable, 
however, that they belong under Dicaeoma Clematidts (DC.) Arth. although the aeciospores 
are somewhat smaller than usual. 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. Until the full life-cycle is definitely ascertained, however, the status of the 
species remains uncertain.
