A NOTE ON INDIAN WHEAT-RUSTS. 
At Jeypore, visited on March 3rd, the soil in the fields was a much 
irrigated, fine blown-sand, extremely free from weeds, No Launea. 
asplenifolia was to be found anywhere in the neighbourhood of the 
city. Launea nudicaulis^ very rare in fields, is not uncommon on 
roadsides and in gardens. It was perfectly healthy, as were the 
wheat and the barley. On 4th March Chaudaspura, 17 miles from 
Jeypore on the Tonk road, was visited, Colonel Jacob having been so 
good as to point out that at this point the soft blown-sand gives 
place to a firmer soil. Here, after a considerable search during 
which Launea nudicaulis was found to be fairly common, a spot was 
reached in which Launea asplenifolia was extremely abundant. 
There was very little rust on the wheat, what there was being the 
supposed Puccinia ruhigo-vera of Shibpur. Launea asplenifolia was, 
however, extremely affected ; most of the plants carried teleutos- 
pores only ; some, however, had uredospores as w^ell. Aecidiosporic 
fructifications were apparently very rare, only one being met with ; 
the aecidia were in this case borne on a malformed leaf, not on a 
specially developed shoot. The most interesting discovery here 
was, however, a plant of Launea nudicaulis^ the species that in 
every other locality had been found to be healthy, with teleutosporic 
fructifications on its leaves. The two Launeas are known indiffer- 
ently as gobii the rust on wheat is known as rori or roli^ The 
name rora or rola was also known, but it was found impose 
sible either to substantiate or to refute the opinion mentioned by 
Dr. Barclay (Journal of Botany, voL 30, p. 47) as prevailing in some 
quarters, that the feminine form roll is used for the supposed Puccinia 
graminiSi the mat^ form rola for the supposed Puccima rubigo-vera. 
It is certain that some of the cultivators use the words indis- 
criminately and declare that both mean the same thing. Others^ 
however, insisted that they were different. Fortunately for them, 
though perhaps unfortunately for the present enquiry ^rust” on the 
spot was hardly to be obtained. The little there was chanced to be 
the supposed Puccinia rubigo^vera which, according to the inform- 
ation obtained by Dr. Barclay, should have been rola; yet the 
inhabitants of the neighbourhood and the owner of the field insisted 
that it was roll. 
At Rewari, March 5th, very little wheat but much barley was 
fourid; neither at all diseased, llere Launea nudicaulis is fairly 
common everywhere, and Launea asplenifolia as elsewhere is local 
but abundant where it occurs ; neither was at all diseased 
From the cultivators it was ascertained that ** rust here is known 
under the name rori^ but the word is not much used ; the term 
employed h I' hung? , the Launeas appeared to have no name.
