II. Uredinia hypophyllous, scattered, round or oval, 0.2-0.6 mm. across, early naked, 
ptlverulent, whitish or brownish, ruptured epidermis noticeable; urediniospores obovoid, 16—- 
19 by 19-23 w; wall light-yellow or colorless, 1-2 » thick, closely echinulate, the pores obscure. 
III. Telia hypophyllous, scattered or crowded and circinating about the uredinia, round, 
0.1-0.3 mm. across, early naked, pulvinate, pale-brown, oftentimes cinereous from germination, 
ruptured epidermis inconspicuous; teliospores oblong, obtuse above, sometimes slightly 
narrowed below, slightly constricted at septum; wall yellowish- or pale golden-brown, 1-1.5

On HELIOTROPIACEAE: 
Heliotropium physocalycinum Donn. Smith, Guatemala. 
Tyre LocaLiry: Antigua, Sacatepequez, Guatemala, on Heliotropium physocalycinum. 
DisTRIBUTION: Mountains of Guatemala. 
12. Puccinia senilis Arth. Bull. Torrey Club 47: 470. 1920. 
II. Uredinia hypophyllous, scattered, round, 0.2-0.4 mm. in diameter, early naked, 
pulverulent, yellow, ruptured epidermis inconspicuous; urediniospores obovoid or broadly 
ellipsoid, 15-18 by 19-23 u; wall light-yellow, 1 « thick, sparsely echinulate, the pores very 
inconspicuous, apparently 3 or 4, equatorial. 
III. Telia amphigenous, scattered, round, 0.1-0.3 mm. in diameter, early naked, pulver- 
ulent, chocolate-brown, ruptured epidermis inconspicuous; teliospores ellipsoid, 18-24 by 
27-40 w, rounded at both ends, somewhat constricted at septum; wall dark chestnut-brown, 
1.5-2.5 » thick, 5-7 » over the pores, often with a semi-hyaline cap over apex, coarsely 
and moderately verrucose; pedicel colorless, up to 50» long, tapering downward, roughened 
below, fragile. 
ON VERBENACEAE: 
Lippia myriocephala Cham. & Schlecht., Guatemala. 
TYPE LOCALITY: Laguna on Lake Amatitlan, Guatemala, on Lippia myriocephala. 
DistRIBUTION: Known only from the type locality. 
13. Puccinia Collinsiae P. Henn. Hedwigia 37: 269. 1898. 
II. Uredinia amphigenous, scattered, round or oval, 0.3-0.8 mm. across, early naked, 
pulverulent, cinnamon-brown, ruptured epidermis evident; urediniospores globoid or broadly 
ellipsoid, 16-23 by 21-26 4; wail cinnamon-brown, 2-2.5 » thick, finely and rather closely 
echinulate, the pores 2, sometimes 3, equatorial. 
III. Telia amphigenous, scattered, round’ or oval, 0.3-0.8 mm. across, early naked, com- 
pact, dark chestnut-brown, ruptured epidermis evident; teliospores ellipsoid or clavate- 
ellipsoid, 19-23 by 31-42 u, rounded above, rounded or somewhat narrowed below, slightly 
constricted at septum; wall chestnut-brown, 2-2.5 » thick, thickened above, 7-10 4, smooth; 
pedicel colorless, up to 50 u long. 
In the original description aecial characters are given substantially as follows: Aecia 
amphigenous, crowded upon reddish spots, cupulate, small; peridial cells yellowish-white, 
ellipsoid, tessellate; aeciospores globoid or broadly ellipsoid, 16-19 »; wall yellowish, appearing 
smooth. ‘The portion of the original collection in the Ellis Herbarium at the New York Botan- 
ical Garden shows no aecia. No other collections have been seen that agree with this material, 
and there is considerable doubt about the host belonging to the genus Collinsia. 
ON SCROPHULARIACEAE: 
Collinsia sp., California. 
TyrE Locality: Potter Valley, Mendocino County, California, on Collinsia sp. 
DISTRIBUTION: Known only from the type locality.
