summit of the branchlets forming often a short peduncle ; 

 general involucre not exceeding the glomerule, constituted of 

 several rows of bracts; the latter green, narrow, woolly, and 

 terminated by a minute scarious yellow glabrous ovate- or 

 cordate-roundish lamina, general receptacle small, not con- 

 spicuous, elevated, bearing numerous flower heads; bracts 

 constituting the ultimate involucres several, oblong or linear - 

 cuneate, hyaline, 1 -nerved, woolly only under the small 

 yellow roundish radiating lamina; flowers minute, 11-24 in 

 each head : corolla slender, gradually widening upwards ; 

 achenes truncate-ellipsoid, subtle-papillular ; pappus very 

 tender, white, formed of very few laxely piumous-bearded 

 somewhat intricate bristles, those at the summit slightly tufted, 

 at the very base connate. 



'Near Charlotte Waters; Lieutenant Dittrich ; collected 

 during Mr. Lindsay's expedition. 



"The specimens seen about hand-high. Leaves ^-§ inches 

 long, the lowest early evanescent. Clusters of flower-heads 

 about ^ inch broad. General receptacle crowded with the 

 persistent woolly involucral bracts. Flower-heads with their 

 proper bracts singly separable ; the latter hardly exceeding the 

 corollas, appressed. Neither stamens nor stigmas exserted. 

 Achenes pale-brown, nearly all ripening. 



"Among congeners this well-marked species finds its "place 

 nearest to C . Francisii, differing, however, already in external 

 feature, in the extensive vestiture, in glomerules constantly 

 broader than long, in more developed general involucre and 

 bright appendages of the ultimate involucral scales. Some 

 relationship to the genus Myriocephalus is indicated by the 

 copiousness of the empty involucrating bracts of the glomerule. 

 On superficial inspection this plant might easily be passed as 

 an A.ngianthus or Craspedia, especially as it was found accom- 

 panied by a small variety of C . phiocephala." 



Professor Ewart adds : — 'The original description is given 

 in English among the literature references in the Botanisches 

 Centralblatt, following a reference from Wing's Southern 

 Science Record, vol. 2, May, 1886, in which no reference to 

 the plant occurs. Evidently Baron v. Mueller sent the 

 description direct to the Botanisches Centralblatt, where it was 

 issued among the records of published literature." 



Among South Australian species C. Dittrichii stands 

 nearest to C. platycephalus, from which it differs in fewer 

 branches, closer tomentum, shorter leaves, compound heads 

 more compact and more globular, pappus-bristles less' flexuose 

 and united at base in a broader ring.
