thickening at apex; membrane pale cinnamon-brown, smooth; 
pedicel as long as the spore, or somewhat shorter, firm, hyaline. 
— On a small terrestrial orchid, Cuernavaca, Sept. 23. 
The spores germinate on the leaf, as soon as mature. 
Puccinia Baccuaripis Diet. & Holw.—On Baccharis cerules- 
cens, near Tula, Oct. 6. 
Puccinia Amphilophii Diet. & Holw., n. sp.—Sori Reet: 
lous (rarely epiphyllous), small or medium sized: uredosori 
brown; spores ovate or broadly elliptical, 23-27 by 20-24, with 
large spines, yellow-brown: teleutosori black, pulverulent ; 
spores broadly elliptical, rounded at both ends, when dry 
depressed at apex and base, moderately constricted, 33-40 by 
26-30"; membrane not at all thickened at apex or slightly 
hooded, chestnut-brown, with short spines : pedicel as long as 
the spore or very little longer, hyaline, hollow, mostly with a few 
appendages on the sides at the base, readily breaking at base 
from the host plant.— On Amphilophium, Cuernavaca, Sept. 22. 
The peculiar pedicels show that this species is closely related to P. apfen- 
diculata Wint., but it may readily be distinguished by the form of the spores, 
the echinulate epispore, and particularly by the appendages occurring only at 
the base of the pedicels. 
PUCCINIA APPENDICULATA Wint. (P. ornata Hark.; P. medus@- 
oides Arthur).—On Tecoma stans, Guadalajara, Oct. 12. 
Puccinia vacua Diet. & Holw., n. sp.—Sori hypophyllous, 
occasionally epiphyllous, scattered: uredosori pale-yellow; 
spores broadly elliptical or ovate to globose, 22-29 by 20-254; 
membrane almost hyaline, echinulate: teleutosori dark brown; 
spores elliptical, rounded at both ends, rarely narrowed towards 
the pedicel, slightly constricted, closely verrucose, brown, hooded 
at apex, 35-60 by 23-28, pedicel up to 8o0yn long, hyaline, not 
very firm.—On Lobelia, Cuernavaca, Sept. 23. 
The teleutospores germinate as soon as mature. Spores have a thicker 
membrane, and are much larger than those of P. Lodbelig Ger. 
Puccinia Triumfette Diet. & Holw., n. sp.—Spots yellow, 
becoming black in the center, round or irregular: sori hypo- 
phyllous, confluent in irregular groups, firm, pulvinate, almost
