NOTES ON THE SYNONYMS. 



1. E. hypericifoUa, R.Br. 



This species is in Index Kewensis referred to as " ex Benth., B.El. iii, 203." 



The reference is as follows : — 



2. E. amygdaUna, var. (?) hypericioUa, Beutlx. 



Leaves of the fruiting branches all opposite, oblong-lanceolate, rounded or cordate at tlie base, and 

 sessile or nearly so. Risdoii Cove. R. Brown. 



E. hypurici/olifi, K.Br. Herb. — The specimens aie larger and good, but in fiuit only. To this form 

 may belong also some of the garden plants desci-ibed from the foliage uiidei- tlie same name. (K.Fl. iii, 1'03.) 



In a letter to me Mr. Rodway speaks thus of var. hypericifoUa : — 



Fruit rather smaller than in var. nitida. These, with E. Risdoni and E. Risdoni, var. elatii, form a 

 ([uite uninterrupted series. 



In his Tasmanian Flora he says : — 



E. amygdalina, var. liyp>ric>folia. Leaves rather broad, opposite and sessile. Fruit rather large, 

 often pear-shaped. A vei-y unstable form, approaching forms of E. Risdoni. 



I cannot separate any specimens I have seen from E. Risdoni, or its var. elata.
