Fig. 3 is a seedling of E. fruticetonmi from Wyalong, for 

 which we are indebted to Mr. Cambage — the unh' seedling he 

 could find. We cannot make out the presence of more than one 

 pair of stem-nodules, which fused on one side (in front, in the 

 photo), but not on the other. The interval separating them at 

 the back is about \ inch wide; and there is a depression at the 

 top which is suggestive of the loss of a branch. The tumoui' 

 had about eight shoots, and there are three branches low down 

 on the stem. No roots had been incorporated. One specimen 

 is not enough to enable one to Judge whether this is merely an 

 exceptional case, or whether one pair is the usual number for 

 this species. The " Mallee-root " shown in PI. xxiv., also from 

 Wyalong, likewise has a tumour of one pair not fused on one 

 side. We do not know the species, but it may perhaps be E. 

 fruticetoriim: and represent the latest stage of a seedling like 

 Fig.S. 



Plate xxi , fig.3, shows the most satisfactory example we have 

 had from Wyalong (much reduced). This is a specimen of one 

 of the small Whipstick Mallees {E. viridis) locally called Blueleaf- 

 Mallee. For the stage at which it has arrived, it may probably 

 be regarded as a fair example of a susceptible Mallee It is not 

 as plump as it might be, but it was collected in a drought. It 

 was trimmed for convenience in transmission to Sydney, but the 

 following dimensions may help to understand its importance : 

 stem-height above tumour, about 6^ inches; diameter of stem 

 above tumour, ^; length of tumour, about 3|; diameter, 1|; 

 diameter of taproot below tumour, y^^. The best aspect of it is 

 shown; at the back, the downward growth is not so satisfactory 

 as in front. The seedling-stem appears to be excentric because 

 of the smaller development on the right side. It has two 

 branches low down; and there are three tumour-shoots. Four 

 lateral roots have been incorporated; but they are insignificant 

 in comparison w^th the well-developed taproot. All the stem- 

 nodules have been included; the concrescence may well represent 

 five pairs; there is a cavity near the summit, which appears to 

 have been caused by borers.

 Behriana, received from Wyalong. Unfortunately, the stem of
