A NOTE ON INDIAN WHEAT-RUSTS. 
confined to the upper surface of the leaf-blade. Launea asplenifolia 
was very common, and specimens were obtained in fields, in a patch 
of village- jungle, on the race-course, by the side of a high-road. In 
every locality it was affected by the Puccinia prevalent at Shibpur ; 
uredospores were plentiful on the upper, teleutospores on the 
under surface of the leaves respectively; abnormal shoots with 
aecidial fructifications were everywhere very Common. 
A barley-field in which the individual plants seemed stunted and 
were far apart was examined, with some. care. It was found that 
many of the plants were affected, though none apparently seriously 
so, by a **rust^’ that from the oval shape of its rusty patches and from 
the occurrence of these on the stem, the outside of the leaf-sheath 
and the underside of the leaf, as well as by the fact of its occurrence 
on barley at all, was evidently different from the rust identified by 
Dr. Barclay with Puccinia rubigo^vera. Later this same rust was 
discovered in an adjacent wheat-field on a wheat-plant. On being 
subjected to minute examination this rust was found to exhibit the 
structural and metric characters of the rust identified by Dr. Barclay 
with Puccinia graminis. One barley-plant was found affected by a 
pale lemon-coloured rust consisting of longitudinally arranged 
parallel lines of very small pustules containing uredospores. All 
that could be said regarding it was that it did not agree well with 
either of the other rusts. 
The search for teleutospores on wheat of the blight prevalent at 
Shibpur was unsuccessful at Mozufferpur, and it is highly probable 
that no teleutospores were present. The Launea is here termed 
titlia ; it is reputed an effective febrifuge. The name used for 
"Rust" is harda\ the two rusts are not differentiated. 
At Gaya, visited on 22nd February as a representative locality 
for South Behar, no blight of any kind was found on the wheat or on 
the barley. Here the wheat and barley-fields had very few weeds, 
none of these being perennials, and a very extended search for 
Launea was unsuccessful. At length in a gram-field, a considerable 
distance from any w’heat, it was discovered and as usual was found 
to be abundant in the spot where it occurred. The plants were 
quite healthy ; growing openly exposed to sun and wind their leaves 
were much thicker and firmer than in Lower Bengal at the same 
sea«:on, though not firmer than they become in Lower Bengal during 
May and June. 
At Mogul Serai, North-Western Provinces, visited on 23rd 
February, no unequivocal example of wheat affected by Dr. Barclay’s 
Puccinia ruhigo^vera was met with. Nor in the barley-fields
