tion ba.sed on a L'Toup of constant characters, for Diels' dis- 

 tinctions do not apply to all the specimens between this variety 

 and the type species. The typical form of the closely allied C. 

 Toddii of F. Mueller^ shows a trifling difference in the size and 

 acuminate character of the bracts, while the perianth tube is 

 rather more slender, is longer in proportion to the lobes, and 

 somewhat more slender, and is more pubescent outside. Even 

 these characters do not apjiear to be quite constant, so that C. 

 Toddii may also ultimately prove to be a variety of C. poly- 

 cephalum when more intermediate material is available. 



Daviesia coitYMBOSA, var. St. Johnii = D. corymbosa, var. 

 viRUATA. (Papilionaceae). 



This plant was recorded in the Victorian Naturalist, Nov.> 

 1906, p. 133, and specimens have since been received from Mr. 

 C. French, Jr., collected at Ringwoiid. They are identical with 

 the D. virgata of Cunningham, which Bentham refers to D. 

 corymbosa, var. mimosoides. The condensed clusters of small 

 flowers and the very narrow leaves would, as suggested by Mr. 

 W. R. Guilfoyle, justify the recognition of a second variety 

 differing more widely from the type than var. mimosoides, even 

 though transition forms occur, but the name should be variety 

 virgata, in recognition of the old specific name for the variety. 



DiPLOTAXis MUUALis, D.C., the wall or sand mustard. 

 (Cfuciferae). 



This introduced alien has been variously referred to as D. 

 nmralis and D. tenuifolia, D.C. It has, however, the small 

 flowers and less divided leaves of the former. Tlie Australian 

 specimens have the leaves less exclusively radical and more on 

 the stem, and are often double the normal height, frequently 

 reaching 12 to 16 inches. The plants also r^how a gi-eater ten- 

 dency to be perennial, but these changes ai'e probably climatic 

 ones, not necessarily of varietal significance, although they are 

 a[)pr()aches towards I), tenuifolia, D.C.
