Puccinia Composite** 



On L. huegelii Benfch., and L. Ullardien Cass. 



Tasmania Mt. Dromedary, near Hobart, Dec., 1894, I. (Rod- 

 way 1 ). Mt. Direction, Oct., 1895, I., III. (Rodway 1 ). 

 Devonport, Jan., 1906 (Robinson). 

 Although material was very plentiful, careful search failed to reveal tl 

 presence of uredospores, and I have given them 011 the authority 

 Cooke. Massee informs me that P. lagenophorae Cooke, is not repi 

 sented in the Kew Herbarium, and he, therefore, cannot refer to the tyj 

 specimens. I have examined scores of plants with this rust upon thei 

 from different localities and at different seasons, and I have never founc 

 uredospores. 



Tfte leaves on which P. hypochoeridis Me Alp., was found proved to 

 not Hypochoeris radicata but Lagenophora billardieri, and the fungus 

 agreed with the above.

 90. Puccinia podolepidis Me Alp. 



0. Spermogonia on small, honey-coloured spots, forming minute, dark- 



coloured points, hemispherical, pale yellow by transmitted ligh 

 with round mouth, without projecting paraphyses, about 1 20 diai 

 Spermatia minute, hyaline, oval, 3 x 2 p. 



1. Aecidia bright orange, on both surfaces of the leaf, numeroi 



generally arranged in circular groups, -which, however, ofte 

 coalesce into large patches ; pseudoperidia cup-shaped, embedded h 

 tissue, with white reflexed, laciniate margins ; peridial cells oblong 

 to lozenge shaped, with striated margins, 28-32 x 16-18 p. 



Aecidiospores deep orange, ellipsoid to subglobose, smooth, 

 24-32 x 16-22 p, or 22-24 p diam. 



III. Teleutosori black, surrounding the aecidia. 



Teleutospores chestnut-brown, oblong to clavate, constricted at 

 septum, smooth, rounded or truncate or occasionally pointed anc 

 thickened at apex (9-12 p), rounded or attenuated towards 

 upper cell darker than lower, 38-54 X 22-32 p ; pedicel per- 

 sistent, hyaline, relatively short. 



X. Mesospores common, similarly coloured to teleutospores or oft 

 paler, ellipsoid, obovate to wedge-shaped or subclavate, rounded 

 thickened at apex, pedicellate, 32-44 x 16-22 p. 

 On leaves of Podolepis hngipedata A. Cunn. 



Victoria Buffalo Mts., Nov., 1903, I. (C. French, jun.). Alj 

 near Bright, Dec., 1904, I., III. (C. French, jun.). 



Several teleutospores had two germ pores in upper cell, one on eith< 

 side, but only one in lower cell. 



The teleutosori were rather sparse.
