Discussion
The b asic terminology for the spore states
of rust fungi was proposed by Tulsane de~ Bary,
Arthur ( 1905 , 1925 ) Cunnigham ( 1930 ) , Cummins ( 1959 )
Hiratsuka ( 1973 ) , Laundon ( 1967 , 72 ) and Sav ile ( 1968 )
The two systems of taxonomical descriptions normally
used to id e n tify the various spore forms ares (a) the
morphological system ; and (b) the ontogenic system.
In the morphological system ( Laundon 1967 ) the
morphology of spores whereas in the entogenic system
( Cummins, 1959 ; H iratsuka 1973b , 1975 ) the po sitio n
of spore states in the l i f e cycle of fungi are the
basis for d escrib in g various ta x a .
In the present study Laundon 's system ( 1967 )
emphasizing the use of morphological characters has
been used, as the b a s is for describin g the various
species collected so fa r .
In In d ia Payak ( 1963 , 1965 ) has reported
aecia on three species of Berberis ( B . a r i s t i t a 0 DC,
B. .jaeschkeana C .K , Schw and B . lycium Royle ) ,
from the western Himalaya p a rt ic u la rly from the Lahaul
valley and Narkhanda ( a l t . 2800 m ) in S im la .
According to Cummins and Greene ( 1966 ) m ajority
of the rusts p a ra s it iz in g on the members of fam ily
1
Festucodeae produce aecia on d iffe r e n t species of
Berberis i . e . P uccin ia brachypodii Otth v a r c brachypodii
produce aecia on B , v u lq a ris , B a ristata and B lycium .
Payak ( 1965 ) however is doubtful about the occurrance
of B .vulgaris in Western Him alaya. 0 C ultural work
done by him has proved that aecia produce^on Berberis lycium
are related to P . brachypodii var b rach y p o dii.
Bilqram i et al ( 1979 ) have recorded aecia
( four species ) on various species of berberis in
India on the b as is of culture work carried out by
Payak ( 1965 ) .
Berberis lycium and B . a r is ta ta on which aecia
are* very commonly produced have been considered as
alternate hosts for Puccin ia brachypodii a rust on
Brachypodium sylvaticum by Bilgram i et al ( 1979 ) #
Sim ilarly aecidium on Berberis jaeschkeana have been
shown to belong to Puccinia poae nem oralis. Thus
out of four species of a e c id ia , on various species
of Berberis only two have been correlated w ith P u c c in ia .
So far aecia on Berberis pseudoum bellata have not
been collected and as such i t is considered as an
anamorjjh, t i l l its primary host is ascertained by
carrying out culture work.
The rust in fected specimen of Phraqmidium b u tle r i
was collected by Inayat ( 1907 ) from Kumaon Him alaya.
E arlier D ie e ls ( 1905 ) had described Phraqmidium rosae
moschata based on a specimen sent to him by B u tle r .
In the u red in ia l characters both resemble each other
but teliospore characters show d if fe r e n t ia t io n .
The teliospores are longer in P . rosae moschatae
and the wall colour is paler when compared to that of
P . b u t le r i . P„ rubi is an autoecius macrocyclic
rust fungus. A ll phragmidium species are autoecious
and occur on species of the Rosaceae.
Puccin ia comprises the larg est genus of rusts
occuring on many fam ilies of angiosperms worldwide,
and m ajority of important p lant d iseases are caused
by species of this genus«
The rust on Centaurea, P B calcitrapae was f ir s t
reported as occurring in In d ia by Sydows ( 1912 )„
Their id e n t if ic a t io n was based on a specimen collected
by Butler from Harwan, Kashm ir, S in ce^th is rust has not
been reported from other parts of India,, According
to Cummins ( 1979 ) , the author of P . centaurea is
Augustin pyramus de-Condolle ( DC ) and not H e inrich
Von M arlius ( Marrt )» In add itio n to the s lig h t
variation in the s ize of spore forms of P . centaurea
it does not warrant the ju s t if ic a t io n of species and
as such Cummins treated it as a variety of P . c a lc itr a p a e .
Puccini a coronata in fects Stip a spp.
According to Bilgram i et al ( 1979 ) the uredo and
t e l ia l stages on the leaves of Stip a spp. had
been collected from Mussorie ( U . P . ) in 1 91 1 .
Cummins ( 1979 ) stated that d iffe r e n t species of
Puccin ia in fe c t various species of S tip a and
Arthur recognised ju s t three species of Puccin ia
in fe c t in g S t ip a . Presently P . coronata on Stipa
has been co lle cted from Dachigam .
P uccin ia menthae co llected from Pahalgam,
Kashmir on Origanum vulqare is an autoecious
m acrocyclic rust fungus. Guchet ( 1906 ) as a
result of h is experiments considered the form on
Origanum as b io lo g ic a lly d is t in c t as the spores
were capable of in fe c t in g the same species only
and fa ile d to in fe c t other three species of M entha.
Puccin ia polyqonii on Polygonum am plexicaule
is a heteroecious macrocyclic rust fungs with the
spermogonial and aecial stages produced on Geranium
spp0 The stages on Geranium have been collected
from Kupwara Kashm ir.
The rusts on Artem esia and Chrysanthemum were
un ited generally under a s ingle species by e a r lie r
w riters like Plowright due to the lack of c le a r
morphological d iffe ren ces between them,. Later
Fischer , Sydows, Grove, W ilso n , Bisby and
others separated them into two d is t in c t species
P . a b s in th ii on Artem *sia and P . chrysanthem ii
on Chrysanthemum.
Treboux ( 1912 ) found that P . tanaceti
may overwinter on Artem esia maritima by mean of
uredosporeso In the present study P . tanaceti
was found to overwinter in the t e l ia l stage on
Artemesia absinthium*
The rust Puccinia v io la e on the leaves of
V io la is known from Sim la ( H„ P . ) , and MUssori
( U . P . ) and Ranipheit ( Kumaon Himalaya ) on
V io la serpentis Sydow and Butler ( 1907 )*
Barclay ( 1890 ) f ir s t described P„ w attiana
on Clematis qouriana Roxbe Later Sydow and
Butler ( 1906 ) reported the same species from
Dehradoon. P a til and Thirum alachar ( 1971 )
reported the same on a new host Clem atis tr ilo b a
from N asik and presently this has been collected
from Dachigam.
Uromyces comprises the second largest
genus of rusts ( about 600 species ) and occurs
worldwide on a wide variety of angiosperm h o sts .
The pathogenic genra in fe c t mostly members of
Gramineae, Leguminosae and Com positae. Uromyces
d iffe rs from Puccin ia in having u n ice lle d teliospores
Uromyces euphorbiae is an autoecious
macrocyclic rust fungus. Arthur ( 1934 ) based
eon culture work recognised four v a r it ie s in i t .
Uromyces mexicanus on Desmodium eleqans
has not been reported from In d ia . Cummins
recorded the species p a ra s itic on various species
of Desmodium,, They are (a) Uremyces antiquanus
(b) Uromyces hedysari p a n ic u la ti (c) Uromyces
mexicanus (d) Uromyces te n u is t ip e s .
The u red in ia l and t e l ia l stages of Uromyces
euphorbiae and Uromyces mexicanus collected in
Kashmir from d if fe r e n t places almost resemble
each other.
