Puccinia Kelseyi Sydow, Monog. Ured. 1: 806. 1904 
O. Pycnia chiefly epiphylious, gregarious, in small groups 0.5-1.5 mm. across, not con- 
spicuous, punctiform, honey-yellow, becoming brownish, globoid, 80-160 in diameter by 
70-150 uw high; ostiolar filaments 30-50 » long. 
I. Aecia chiefly hypophyllous, gregarious, more or less crowded in groups 1-4 mm. across, 
on slightly discolored spots, cupulate, slightly bullate, short, 0.2-0.4 mm. in diameter; peridium 
colorless, the margin irregularly lacerate, slightly recurved; peridial cells rhomboidal, 21-29 zu 
long, the outer wall transversely striate, 4-7 » thick, smooth, the inner wall rather finely ver- 
rucose, 2-4 » thick; aeciospores globoid, 15-24 by 18-27 u; wall colorless, 1.5-2 u, evenly and 
finely verrucose. 
On PRIMULACEAE: 
Glaux maritima L,., Montana, Wyoming; Saskatchewan. 
Steironema ciliatum (L.) Raf. (Lysimachia ciliata L..), Colorado, North Dakota; Manitoba. 
Il. Uredinia epiphyllous, on the rough surface, intercostal, arising from the mesophyll, 
numerous, oval, 0.3-0.5 mm. long, early naked, yellowish, ruptured epidermis conspicuous; 
urediniospores globoid or broadly ellipsoid, 23-28 by 26-35 u; wall pale-yellow, uniformly 
thick, 3-4 «, moderately and strongly echinulate, the pores 6-8, scattered, rather indistinct. 
III. Telia epiphyllous, sometimes caulicolous, intercostal, numerous, crowded, often 
confluent, oblong or linear, 0.5~2 mm. long, early naked, blackish-brown, ruptured epidermis 
conspicuous; teliospores obovoid or lance-oblong, 21-27 by 42-64 4, obtuse or acute above, 
somewhat narrowed below, slightly constricted at septum; wall dark chestnut-brown, moder- 
ately thin, 1.5-2 4, strongly thickened above, 7-13 4; pedicel golden-brown, rather thick, as 
long as spore or longer. 
This species is morphologically indistinguishable from Nigredo Polemonit (Peck) Arth., 
except in the possession of two-celled teliospores. ‘The two forms are maintained separately for 
convenience but should be united eventually under one name.
