See Mr. Blakely's papers on Loranthaceee in Proc. Linn. Soc, N.S.W., XLVII. 

 They include a very large number of references to species parasitic on Eucalyptus, 

 together with excellent drawings of the parasites themselves. 



Following is a note on a parasite allied to the Sandalwood, which is worth 

 emphasising, as we have notes on so few parasites other than the Mistletoes. 



Speaking of E. calycogona Turcz., at Pinnaroo (J. M. Black, Journ. Roy. Soc, 



S.A., XLIII, 39, 1919) " In many instances specimens of Fusanus acuminatus (' Native 



Peach ') were growing — probably parasitically — so close to these trees that the stem 



'of the Fusanus was impressed into that of the Eucalyptus, forming a deep channel 



along one side. 



(b) Hemi-epiphytes (Strangling Figs). 



" Effects of growing cells on Environment," and " Disruptive Force of Fungi, 

 Roots, &c." (Kerner and Oliver, I, 513) may be referred to. Fig. 130 shows elevation 

 of a block of stone in consequence of the growth in thickness of a Larch root. Its 

 weight is estimated at 1,400 kg., and the root concerned is only 30 cm. in thickest 

 diameter. " An instance is also known in which a stone of 160 kg. (352 lb.) was raised 

 and shifted by the growing fructification of a fungus of the mushroom tribe ; ' 

 (p. 514). 



Other trees are quoted, but they all dwarf into insignificance in their effects as 

 compared with the devastation caused by tropical Figs (Ficus). I have no illustrations 

 of Eucalypts, but observers have often noticed what great disruptive force they are 

 capable of exercising. 



Epiphytes. 



One of the most charming sights 1 have ever seen was that of huge masses of 

 Dendrobium aemulum R.Br., flowering on the trunks of E. paniculate/, at Wyong, N.S.W. 



Cymbidium canaliculatum R.Br., is epiphytal on spp. of Eucalyptus in New South 

 Wales, but especially on E. clavigera A. Cunn. in N. W. Australia (W. V. Fitzgerald). 

 It is common on Box trees, resting in the forks. These epiphytes do not injure the 

 trees, so far as I know. The subject of epiphytes on our Eucalypts may well be 

 taken up by an observer. 



(c) Fungi. 



I am much indebted to Mr. Edwin Cheel, my chief Botanical Assistant, who has 

 favoured me with the following valuable list and notes of fungi recorded as having been 

 found on various species of Eucalyptus. Unfortunately, the particular Eucalypt is 

 not mentioned in very many cases. It is obvious that there is still a wide field of 

 research indicated by Mr. Cheel. 



The list includes 113 species, representing 31 families and 71 genera of fungi, 

 found on 35 species of Eucalyptus. Cooke and Harkness (2) have recorded 42 species,
