K. vitellina. The fruits of the specimen labelled "E. 

 amygdalina" by Tate are a trifle smaller than those gathered 

 between Mount Gambier and Glencoe (about 5 mm. long by 

 6 mm. diameter at the summit), but otherwise agree with 

 them. All the localities mentioned lie near together, and 

 are in the same class of country. Mr. Maiden considers 

 E. vitellina to be a hybrid between E. paucifiora, Sieb. (E. 

 cori,acea, A. Cunn.) and E. amygdalina, Labill., which has 

 become more or less fixed. 



E. leucoxylon, F. v. M. Wirrabara Forest. "Blue 

 Gum." The typical form, with smooth, white and bluish 

 bark on the stem, is found here, but there are also many 

 trees with similar flowers and fruits, but with a rough black 

 bark. The dark-barked form also occurs at Bordertown, with 

 the point of the operculum much shorter than usual. Maiden 

 (Crit. Rev. Euc, ii., 82) points out that Bentham confused 

 E. leucoxylon, F. v. M., with E. sideroxylon, A. Cunn. In 

 distinguishing the two species Maiden says that E . sideroxylon 

 has the bark "black, furrowed, and rugged." while E. 

 leucoxylon has it "whitish or bluish, smooth." It appears, 

 therefore, that we have in South Australia either a form of 

 E. leucoxylon closely approaching E . sideroxylon, or else the 

 latter species itself. 



E. oleosa, F. v. M. Leigh Creek. Here a rather tall 

 tree, with lanceolate black-dotted leaves like those of E. 

 calycogona, Turcz., var. gracilis, Maid. 



Melaleuca glomerata, F. v. M. Leigh Creek. This is 

 a 'paperbark teatree," the bark white on the outside, fibrous 

 beneath, and pealing off in thin strips. 



Umbelliferae. 



Didiscus glaucifolius, F. v. M. Lyndhurst Railway 

 Station. My field-note says, "Flowers white; leaves glaucous." 

 In other northern specimens from Oodnadatta and Strzeleeki 

 Creek most of the dried petals are blue, so that probably both 

 colours occur. 



CONVOLVUL ACEAE . 



t 

 Convolvulus erubescens, Sims. Three forms of this vari- 

 able species were found at Hawker: — 1, limb of corolla pink, 

 rotate, almost or quite lobeless, 15-20 mm. diameter when 

 open; leaves narrow, entire in the upper part and with 2 

 spreading, emarginate auricles at base. 2, limb pink, 8-10 

 mm. diameter, spreading-erect, with prominent rounded lobes; 

 leaves narrow, lobed, with lobed auricles at base. 3, limb 

 white, 6-10 mm. diameter, spreading-erect, lobes subacute; 

 leaves broadly ovate-cordate, bluntly lobed all round.
