FROM THE FALKLAND ISLANDS. 225 
PHRAGMIDIUM HunI-GEOIDIS, Cotton, sp. nov. P. incrassatum, Crié in 
Compt. Rend. Ixxxvii. (1878) p. 532 (non Link). 
Uredosori epiphylli, congesti, minuti, 0°3-0°5 mm. diam., interdum con- 
fluentes, bullati, aurantiaco-flavi, profunde immersi dein exeidentes. Spore 
ovate vel oblongæ, 15-25 x 12-15 p, flavidæ, basi excepta acute echinulatæ, 
aparapliysate. 
In foliis Rubi geoidis, Roy Cove, Vallentin, 60. 
Crié (78) recorded a Phragmidium on В. geoides, referring it to P. ineras- 
satum, Link (=P. Rubi, Wint.). Since that date our knowledge of the 
Uredineæ has greatly increased, and it is evident that the Falkland Islands 
species differs from the true P. Rubi if only in the smaller spores. Mr. Grove 
drew my attention to unusually bullate sori and the absence of clavate para- 
physes, which are so marked a feature in the uredosori of most species of 
Phragmidium. The sori penetrate the whole depth of the mesophyll, and 
at length drop out, leaving a deep cavity. J. geoides occurs only in Fuegia 
and the Falklands.

Е. Falklands : on Acena ascendens, d’ Urville, teste Crié. 
Distrris. N. Europe, Siberia, Japan, N. America. 
As has been the case with the last plant, further investigation will probably 
show that the rust-fungus on Acena ascendens is a distinct and new species.

For assistance with this and the following species I am indebted to 
Mr. C. G. Lloyd. He informs me that the photograph and spores indicate 
that specimen 46 is referable to L. elatum, though it differs from the usual 
form in the absence of stalk. The single Hooker specimen referred by 
Berkeley to this species was wrongly named, but is now indeterminable.

W. Falklands ; Shallow Bay, Vallentin, 45 & 46. 
DisrriB. Europe, №. America, Australia. 
Photographs and specimens leave no doubt as to the identity of this. 
Mrs. Vallentin notes that the plants sometimes grow to an immense size, 
one specimen measuring 3 feet 10 inches in circumference. The capillitium 
is about 10 p thick, and the spores smooth, olive, globose, and 4 ш diam.
