A NOTE ON INDIAN WHEAT-RUSTS.

undoubtedly that met with for the first time at Ferozepore and met 
with again at Gujranwala and at Amritsar, in which there were teleu- 
tospores as well as uredospores on the wheat. 
The disposition of the uredosporic pustules in this blight was 
much the same as in the case of the Mozufferpur Rust, the outside 
of the leaf-sheaths and the outside of the culms being much more 
affected than the leaf-blades. But the uredospores themselves in 
this case differ altogether from those of the “ Mozufferpur Rust, ” and 
the teleutospores, while differing as much as the uredospores do in 
structure, deviate still further, in that the teleutosporic pustutes do not 
rupture the epidermis of the leaf or stem on which they occur, as 
those of the ** Mozufferpur Rust*^ do. On the other hand this Feroze- 
pur Rust has uredospores extremely like — indeed not distinguish- 
able by tangible characters from — those of the “ Shibpur Rust/’ and of 
the Puccinia as Launea asplemfolta. Still it does not follow that 
this ** Ferozepur Rust ” is the same as the Shibpur Rust indeed the 
presumption is quite the reverse, since in this case we have a rust 
with teleutospores on wheat, in the Shibpur Rust ” one without teleu- 
tospores on the wheat. And it is certainly not the same Puccima as 
is found on Launea asplenifolia for the teleutospores of the two are 
* tally unlike. We must therefore have in this ** Ferozepur Rust” 
either a very distinct manifestation of the ‘ Shibpur Rust,’ and at the 
same time find in it a proof that the Puccinia on Launea asplenifolia 
is in no way connected with rust ” on wheat ; or what, so far as the 
evidence at present available goes, is more probable, find in it a third 
** rust ’* on Indian wheat. 
The structural and metric characters of the ** Ferozepur Rust” agree 
so exactly with those credited to P, tubigo-vera by Oersted, Winter 
and Plowright, and the disposition of its pustules, except that none 
were found on the glumes, is so like the disposition of the pustules 
in P, rubigo-vera that we should have very little hesitation in iden- 
tifying it with European species, but for the difficulty as to its aecidial 
fructification. No Borages ” have yet been discovered in India 
—though these have been long and diligently looked for by many 
competent observers— to carry any Puccinia whatever. And if 
this is at best hut negative evidence, it still affords, in our 
opinion, an excellent reason for retaining an open mind regarding the 
point. It should be here observed that the rust ” obtained at 
Lahore, though teleutospores were not found, bad its pustules dis- 
posed in the same manner as those of the Ferozepur Rust ’* and not as 
in the “ Shibpur Rust. ” As only the late sown wheat was rusted at 
Lahore, the absence of teleutospores may simply have been due to
