HIMALAYAN LEAF FUNGL 



Dr. James Fleming, late of Delhi, has forwarded us a small 

 but interesting collection made by himself during a trip to the 

 Himalayas. He informs us that they were obtained at a con- 

 siderable elevation, corresponding to a temperate zone. It is 

 worthy of note that two British species, JEcidium ruhellum and the 

 Uredo of the agrimony are amongst the number. The Uromycesow 

 box leaves appears to correspond with the Puccinia Buxi of 

 Europe. Until now we are not aware that any Puccinia has been 

 found on a crucifer. Dr. Fleming's specimen was accompanied 

 by the siliqua, and it is not improbable that the Puccinia occurred 

 on some species of Brassica or Sinapis. It is not often that a 

 small collection of only ten specimens possesses so much interest. It 

 serves to indicate what a rich unexplored country for the mycologist 

 lies at the base of the Himalayas. 



Uredo punctoidea. ■ Cooke. — Hypophyllous, aggregated in 

 irregular patches circumscribed by the veins of the leaves. Sori 

 minute, punctiform, at first sub-hemispherical, then ruptured 

 above. Pseudo-spores nearly globose or oval, orange, tuberculose. 



On pinnate leaves of some leguminous tree. Himalayas. 



Closely resembling in habit and appearance Uredo Hi/pericorum. 



Uredo Fotentillaxum. B.C. — On leaxes of Agriinonia. Hima- 

 layas. 



Uromyces ambiens. Cooke. — Hypophyllous, scattered. Sori 

 irregular, confluent, dark brown, compact, forming rings, enclosing 

 a cluster of spermogonia in the centre. Pseado spores brown, 

 obovate, with long slender hyaline pedicels. 



On box leaves (Buxus s^empervirens 1). Himalayas. 



Uredo Clematidis. Berk.— On leaves of Clematis. Himalayas. 



Puccinia Cruciferarum. Coo/ie.— Hypophyllous, scattered or in 

 circinate clusters. Sori irregular, pulverulent-vinous brown. 

 Pseudo-spores, brown, elliptical, scarcely constricted, on short 

 fugacious pedicels, ajDiculate above. 



On leaves of some cruciferous plant. Himalayas. 



In habit resembling Puce, j^ulverulenta, Grev., bat darker and 

 with different fruit. 



Puccinia dissiliens. Cooke. — Hypophyllous, scattered. Sori 

 discoid, convex, compact, dark brown. Pseudo spores on long 

 hyaline pedicels, brown, constricted at the septum, freely separating 

 into two subconical cells, of which the basilar usually remains 

 attached to the pedicel. 



On leaves of Riimex. Himalayas. 



JEcidium rubellum. Ptvs. — On leaves of Rumex. Himalayas. 



Ailographum vagum. Desm. (1)—0n coriaceous leaves. Hima- 

 layas. 



Without fruit, but probably this species. It occurs on the 

 same leaves with an Erineum.
