(a) Leaves 6 inches or more long, acuminate about ^-inch broad, 

 3-5 nerved. — 3. Var. saligna.

or more broad, 5-9 or occasionally 11 -nerved, rather obtuse ; 



flowers reddish or crimson,; fruits large. — 4. Var. sanguinea.

 acute, 3-4 inches long, 5 to 7-nerved ; flowers greenish or greenish- 

 white. — 8. Var. viridiflora. 



Leaves 1| to 2| inches long, 3-5 -nerved ; flowers pallid white.- — 

 9. Var. albida. 



(2). J/. Leucadendron, var. mimosoides. Nov., (.'omb. 



M. mimosoides, A. Cunn., Herb Schauer, M.s.s., Walp., Repertorium 

 Botanices Systematicae, Tomus ii., p. 927 (1843). 



The original description is as follows : — " Ramis elongatis penduHs, in- 

 novationib. glabris, ; foil, alternis coriaceis rigidis subverticalib. elongato- 

 lanceolatis subfalcatis in petiolum attenuatis longe acuminatis 3-5 nervib., 

 sub-venosis opacis imperforatis ; spicis subapicalib. elongatis interruptis 

 glaberrimis ; calycib. ructus urceolatis truncatis." The habitat given is : 

 " In Nova Hollandia oriental! tropica, A. Cunn., Herb., No. 253/1819." 



Benthara (Fl. Aust. iii., p. 142) quotes this and several other species as 

 synonyms under M. Leucadendron. Bailey (Syn. Queensl. FL, p. 170, Queensl., 

 Fl. ii., No. 601, Cat. Queensl. Woods, No. 171, and Comprehensive Catalogue 

 of Queensland Plants, p. 188), regards it as a distinct variety and records it under 

 the name M. Leucadendron, var. saligna. 



Having made a close examination of the very large series of specimens in 

 the National Herbarium, Sydney, I am of the opinion that the following speci- 

 mens belong to the M. mimosoides of Cunn., in Walp., but are really too clase to 

 M. Leucadendron L. to be regarded as distinct species, but may be regarded as a 

 variety under the name var. mimosoides. The specimens labelled M. Leuca- 

 dendrcm, var. saligna, by Bailey, from Bentinck Island, very closely resemble 

 the photograph of M. Leucadendron from the Linnean Herbarium reproduced 

 by Baker and Smith, I.e., Plate viii. The rachis of ilf. LeuMxdendron is described 

 by various botanists as being perfectly glabrous, and the flowers white, and 

 leaves 5-nerved and falcate or sickle-shaped. From a close examination of the 

 following specimens it will be found that the rachis is also perfectly glabrous, 

 and the flowers opposite or somewhat whorled or sub-verticillate, and the 

 leaves distinctly falcate or sickle-shaped, with five nerves. The flowers, how- 

 ever, are iTi most cases pinkish or reddish, as mentioned by Bailey, I.e.
