tents granular with conspicuously large oil globules, 16.2-25 x 
237 - 38.7 fi¬ 
ll. Hypophyllous, sori round, scattered, pale tawny yellow, 
small; spores globose to slightly angular, almost hyaline, minutely 
and sparsely echinulate, thin walls, contents granular, 22.5-25 /* 
in diameter. 
III. Hypophyllous, sori round, small, scattered or occasion¬ 
ally forming rings, black, pulverulent; spores very dark reddish 
brown, short elliptical, slightly or more usually not at all con¬ 
stricted at the septum, rounded at both base and apex, cells equal 
in size, walls rather thick, closely beset over both cells with 
medium large transparent papillae, 22.5-25 x 25-31.2^; pedicel 
stout, hyaline or sometimes slightly colored next the spore, spat- 
ulate flattened near the base, about 5 fx in diameter by 50-62.5 p 
long. 
This species shows relationship to P. menthae, but a com¬ 
parison of it with abundant material of the latter from both 
America and Europe shows many conspicuous and constant diff¬ 
erences which readily separate it from that species, — the very 
dark brown teleutospores, the dense covering of papillae on the 
basal cell as well as the apical one, the absence of any prominent 
apical papilla, and the stout pedicel which is comparatively short 
and conspicuously spatulate flattened near the basal end.

I. Aecidia closely scattered on under surface of the leaves 
and along the stem, diminishing the former in size and causing 
the latter to grow strictly erect (the normal branches being pros¬ 
trate trailing) ; basal portion of the aecidia hemispherical, from 
the top of which extends the long white cylinder, 3-4.5 x 5.6-10.5 
mm. irregularly jagged on the margin, not revolute, readily break¬ 
ing away so that older individuals are much shorter; spores angu¬ 
lar ovoid, oblong or globose hyaline, walls medium thick, minutely 
and closely verrucose, 16.2-21.2 x 25-32.5 fi. 
II. Hypophyllous; sori scattered or clustered, in the latter 
case somewhat discoloring a spot on the leaf to straw-yellow, 
small, round, pale pinkish yellow, fading on drying; spores mostly 
elliptical-oblong, frequently ovoid, nearly transparent, wall thin, 
finely echinulate, contents granular, 18.7-21.2 x 25-30 /x. 
III. Sori mostly on the angles of the trailing stems from 
which grow the distorted branches which bear the aecidia, rarely 
found on the under surface of the leaf on the veins, very small, 
1.1-1.9x3-37 mm., dark brown, surrounded by ruptured epi-
