4524 Plantae Guatemalensibus, ed. by Joun DonNELL SmituH, in the Columbia 
University collection. 
This species is known only from the localities listed above in Guatemala. 
It is easily separated from all other species on Vernonia, having distinct rugose 
markings on the teliospore wall, and by the small spores thickened at the 
apex. 
24. PuccINIA PINGUIS Diet. Hedwigia 36:32. February 1897; 
not P. pinguis Diet. and Holw. July 1897. 
Known only from the type collection on Vernonia platensis, Serra Geral, 
Brazil, February 1891, E. Ule 1692. A part of the type from the herbarium of 
Hotway has been examined, and it proves to be quite distinct. The teliospores 
are irregularly ellipsoid or oblong, 24-30 by 42-52y, slightly or not constricted, 
wall chestnut brown, 2.5-4m thick, apex usually abruptly thickened by a sub- 
hyaline papilla to 5-gu. Some spores show scarcely any thickening. The 
wall is obscurely and very minutely rugose. A few colorless urediniospores 
were observed in one mount. They are globose or broadly ellipsoid, 20-23 by 
20-23, wall 1-1.5 thick, very minutely and closely echinulate. 
25. Puccinia Kuntzii, sp. nov. 
O and I. Pycnia and aecia unknown. 
II. Uredinia not seen; urediniospores intermingled with telio- 
spores, somewhat irregularly globoid to ellipsoid, 26-29 by 29-34 #5 
wall golden brown, 3~3.5 u thick, closely echinulate, pores obscure, 
probably scattered. 
Telia hypophyllous, numerous, pe Re roundish, 0.2- 
©.5 mm. across, early naked, becoming pulverulent, blackish brown, 
ruptured epidermis not conspicuous; teliospores broadly ellipsoid 
or oblong, rounded at either end, occasionally somewhat narrowed 
below, not or slightly conatricted. wall dark chestnut brown, © 
5-5-7.5 » thick, apex slightly thickened 8-10 y, prominently and 
closely verrucose-rugose, pore of lower cell situated midway between 
septum and pedicel; pedicel colorless, flexuous, one half to twice 
length of spore, often deciduous. 
The specimen on which this species is based was obtained from a phanero- 
gamic specimen in the herbarium of the New York Botanical Garden, labeled
