into certain forms, which, however, run into each other : — 

 Form. 1. Leaves thicker, and usually narrower; often 

 more or less glaucous. Oil dots not prominent. Fruits nearly- 

 sessile, reminding one of those of incrassata, var. dumosa, and 

 with little or no rim, except when unripe. This form, the 

 type, is nearest to that named E . cajwputea,^^^ F. v. M. This 

 form includes E. odorata, Behr., var. erytlivandra, F. v. M.(^) 

 This is so named because of its dark-coloured (red) filaments 

 which do not show this colour (or very rarely) when fresh, 

 but which darken with age. I got Form 1 mostly on the 

 Port Lincoln- Wangary Road. At 7-8 miles it is in mallee 

 form. At 13 miles we have a "Peppermint Mallee" or 

 ''Black Mallee." I only got green buds and unripe fruits and 

 suckers. Smooth bark, or a little ribbony, a very little scaly 

 near ground. Wood pale-brown like normal odorata. At 13- 

 14 miles I collected a very broad-leaved form, which at the 

 time reminded me of F. incrassatay var. dumosa. At the 

 same time it has not the fruit-rim of typical F . odorata, ex- 

 cept perhaps when young. At 14-15 miles are small trees, 

 almost mallee-like. Smooth, ribbony towards butt, with a 

 little scaly bark. Timber brownish towards centre. F . ca'ju- 

 '])}itea, F. V. M., apjDcars to be that form of F . odorata near- 

 est to F. polyhractta, R. T. Baker {F . friiticelorum , F. v. 

 M.). The oils of F . odorata and E . 'polyhractea are identical 

 in composition. See "Research on the Eucalypts" (Baker and 

 Smith). 



Form 2 (F . calricidtrix, F. v. M.). Leaves sap green, 

 thinnish, and oil dots rather prominent. Fruits pedicellate 

 and with marked rims. The juvenile leaves sometimes glau- 

 cous ! Murray Bridge specimens have leaves with crenulate 

 margins and prominent oil dots ; brown, not red, timber. 

 Some of the fruits are pear-shaped (? showing hybridization). 

 This is the ordinary odorata of Murray Bridge, and some are 

 large trees ; Mr. Cambage and I did not find any tree be- 

 longing to the odorata group with a red timber. At Cape 

 Jervis at first forms dense, stunted masses of 1-3 ft. Almost 

 mallee-like, suckers narrowish. Oil dots of leaves prominent: 

 variation in width of juvenile leaves remarkable. A little 

 further from the sea it is a small tree of, say, 20-25 ft., 

 forming a belt. It is nearest of all the Mallees to the shore. 

 It is the commonest tree Eucalypt about Port Lincoln. It 

 seems to prefer limestone. It is sometimes a small, strag- 

 gling tree with black, rough bark. It is also a medium- 

 sized tree of drooping habit. The oil dots are not so promi- 

 nent as in the Murray Bridge specimens.
