Puccinia Goodeniaceae. 



70. Puccinia dampierae Syd. 



Sydow, Mon. Ured. I., p. 193 (1902). 

 Sacc. Syll. XVIL, p. 315 (1905). 



I. Aecidia on stems and both surfaces of leaf, gregarious, bright 

 orange ; pseudoperidia with white reflexed and torn margins, ^ ^ mm. 

 in diam. ; peridial cells lozenge-shaped to oblong, with thick striated 

 margins, 30-40 p long. 



Aecidiospores orange, subglobose, ellipsoid to oblong, finely 

 echinulate, 15-17 p diam. or 17-19 x 13-14 p. 



III. Teleutosori on stems, scattered or aggregated, round or oblong, 

 about 1 mm. diam., compact, dark-brown, girt by the ruptured 

 epidermis. 



Teleutospores clavate, rounded or acute at apex and strongly 

 thickened (8-11 /;), constricted at septum, attenuated down- 

 wards, rarely round, smooth, brown, 48-66 x 16-26 p.; pedicel 

 yellowish, persistent, up to 80 JJL long. 



X. Mesospores intermixed with teleutospores, clavate, 40-55 x 14-22 /*. 



On stem and leaves of Dampiera stricta R. Br. 



Victoria Monbulk, Dec., 1905, I. (C. French, jr.). 



On wings of the stems of Dampiera alata Lindl. 

 West Australia, III. (L. Preiss). 



Though I have not seen the West Australian specimens I prefer to 

 regard the aecidia found in Victoria as a stage of the same fungus. If they 

 should prove to be unrelated they would be easily separable at any time. 



71. Puccinia gilgiana P. Henn. 



Leschenaultia. 



Hennings, Hedw. XL., p. (95) (1901). 

 Sydow, Mon. Ured. I., p. 194 (1902). 

 Sacc. Syll. XVIL, p. 314 (1905). 



Aecidium perkinsiae P. Henn. Hedw., XL., p. (96) (1901). 



I. Aecidia on thickened and slightly deformed parts, gregarious or 



scattered ; pseudoperidia hemispherical to cup-shaped, semi- 

 immersed, yellowish to ruddy ; peridial cells round or oblong- 

 polygonal, subhyaline, reticulate, 18-24 X 16-20 /u. 



Aecidiospores subglobose or ellipsoid, angular, finely echinulate, 

 yellowish, 15-20 /u diam. 



II. Uredosori on stems, gregarious in streaks, oblong, surrounded or 



almost covered by the ruptured brown epidermis, somewhat 

 pulverulent. 



Uredospores subglobose, ovoid or ellipsoid, yellowish to brown, 

 echinulate, 14-21 x 12-18 p. 



III. Teleutosori similar, but black. 



Teleutospores clavate or oblong, constricted at septum, smooth, 

 obtusely rounded or truncate at apex and slightly thickened (up 

 to 5 p.), obliquely papillate and occasionally crested, rounded at 

 base or attenuated, brown, 30-45 x 16-22 //, average 42 X 20 /u ; 

 pedicel brownish, thick, persistent, 30-50 fj, long.
