0. Spermogones epiphyllous, sparse, in small groups, honey-coloured. . 
I. Aecidia hypophyllous, in small groups, or scattered, seated on pallid 
spots, orange-yellow. Peridia cupulate, 0-25 mm. diam., margins short, 
erect, or somewhat recurved, finely laciniate, white. Spores globose or 
elliptical, 16-24 x 16-22 mmm. ; epispore hyaline, densely and minutely 
verruculose, 1 mmm. thick, cell-contents orange-yellow 
II. Uredosori ерата chiefly hypophyllous, and caulicolous, on 
leaves scattered, orbicular, 0:5-1 mm. diam., on stems elliptical, up to 
mm. long, cinnamon - brown, pulverulent, surrounded by the ruptured 
epidermis. Spores elliptical, obovate or subglobose, 22-28 х 18-22 mmm. 
Е pallid cinnamon - brown, sparsely and moderately echinulate, 
1-5 mmm. thick, = осе vacuolate, cinnamon; germ-pores 2, super- 
büsitcrial conspic 
ПІ Teleutosori hypophyllous and caulicolous, minute, orbicular, 
0-25-1 mm. diam., colate-brown, pulvinate, semi-compact, surrounde 
by the ruptured oriens Spores gin less commonly elliptical, 
35-50 x 15-22 mmm.; apex rounded, seldom acuminate, thickened 
up to 14 тт. ; base eluate lower cell narrower and lighter in 
colour than the upper; slightly constricted at the bacon epispore 
smooth, golden-brown, 2 mmm. thick in upper cell, 1-5 mmm. in lower ; 
pedicel persistent, hyaline, tinted at the apex, up to 40 x x 10 mmm.

Distribution : Europe ; Siberia ; North America ; Chile. 
Both hosts are endemic and common throughout. Cheeseman (1906, 
267) states that Asperula perpusilla would almost be better placed in 
Galium, as the corolla-tube (the only character upon which the genus is 
separated from Galium) is much shorter than is usual in this genus. 
. Several S edd are recorded as occurring on Galiwm in Europe. Of 
these, P. di et S. differs in the uredosori being absent; 
P. Valantiae Por in both aecidia and uredosori being absent; and 
P. Celakovskyana Bubak in the absence of эур P. Asperulae- -odoratae 
Wurth is separated, as it occurs on Asperula and is unable to infect 
Galiwm ; morphologically it is practically T dentienl with P. punctata, so 
that I can see no valid reason for maintaining it other than as a biological 
form of this latter species.
