NOTES ON THE SYNONYMS. 



1. E. hyperieifolia, B.Br. 



This species is in Index Kewensis referred to as " ex Benth., B.F1. iii, 203." 

 The reference is as follows : — 



2. E. amygdalina, var. (?) hypericiolia, Benth. 



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

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



E. hyperieifolia, R.Br. Herb. — The specimens are larger and good, but in fruit only. To this form 

 may belong also some of the garden plants described from the foliage under the same name. — (B.FL iii, 203.) 



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



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

 quite uninterrupted series. 



In his Tasmanian Flora he says : — 



E. amygdalina, var. hyperieifolia. Leaves rather broad, opposite and sessile. Fruit rather large, 

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



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