ON RUBIACEE 167 
On Galium Cruciata. Not uncommon. Uredospores, May 
—July; teleutospores, August, September. (Fig. 116.) 
Distinguished at once from P. Valantiae on the same host by the dark 
colour of its teleutospores, and their very great and dark apical thickening. 
The presence of uredospores also distinguishes them ; in P. Celakovskyana 
the two kinds of sori are often present together on the same leaf, the 
uredo-sori pale brown, and the teleuto-sori almost black. 
According to Bubak, almost its only distinction from P. punctata lies 
in the absence of the zcidium whose place is taken by the primary uredo- 
sori. Wurth reports it also (J.c.) on G. pedemontanum on the continent, 
but demonstrated by culture-experiments that it could not be transferred 
to other species of Galiwm. Most of the records of P. punctata on 
G. Cruciata probably belong to this species, which certainly shows few 
morphological distinctions from the former; [ find, however, that the 
teleuto-sori are larger, more numerous, and more compact in this species 
than in that found on G@. palustre.

This Leptopuccinia is very distinct from P. Celakovskyana, which also 
lives on G. Cruciata, not only by the absence of uredospores, but also by
