TJredospore. The uredospores are 
developed from the same sori as the 
teleutospores, and precede them ; sub- 
globose, brownish, minutely echinulate,

A very distinct and remarkable 
species, a specimen of which was 
kindly communicated by the author. 
The teleutospores having three cells 
are just the reverse of those met 
with in other species, inasmuch as 
there are two basal cells divided by a 
vertical septum and a single apical 
cell ; the pedicel at first sight ap- 
pears to be a downward continuation 
of the median septum, but when 
examined carefully it is found to be 
organically attached to one of the 
basal cells only, close to the septum, 
Teleutospores of Triphragmium. as in Fig. 4, also the two spores to 
the right also belonging to Fig. 4. When the two basal cells are 
alone present, the structure is identical with that most usual in the 
genus Diorcliidium , a spore composed of two cells placed laterally 
and divided by a vertical septum. In the last named genus I find 
that the pedicel has frequently the oblique mode of insertion, and 
is not a continuation of the septum, which, indeed, it could never 
be if the idea previously mentioned respecting the structure of the 
teleutospore be correct. 
Triphragmium echinatum, Lev. (Fig. 5 ). 
Teleutospore. Sori more ‘or less elongated, often confluent and 
broadly diffused, black, pulverulent, on the leaves, petioles, and the 
stems ; spores radiately three-celled, obtusely triangular or almost 
spherical, 25-35 p diameter; epispore dark brown, ornamented 
with 8-13 long, slender, brown, cylindrical or slightly tapering 
spines, 8-11 X l’5-2 p ; apex obtuse or usually furnished with 
2-3 very minute, more or less recurved spicules ; pedicel 35-40 x 
6-7 p, hyaline, deciduous.
