Hoogland were Baeuerlen 864 (MEL 106568 and MEL 106569) and Barnard s.n. (MEL 
106570 and MEL 106571). The former specimens have since been re-determined as 
D. jerseyana and the latter confirmed as D. pruriens. MEL 106568 has attached a draft 
description of the specimen in Mueller's hand, but, there is no annotation of the name 
on either the note or on the sheets by Mueller. 
The first reference to this new taxon was in Bailey (1895), 'D. jerseyana, F. v. M., found 
on the southern border of Queensland and in the adjoining scrub lands of New South 
Wales'. Bailey (1900) listed var. jerseyana (with D. jerseyana F. v. M. as a synonym) as a 
variety, validating the name with the brief note that it is smaller in all parts than the 
type variety. It was not till 1909 that Bailey (p. 169) gave his own name as author of the 
variety, when he listed under Davidsonia, var. jerseyana Bail. = D. jerseyana F. v. M. 
As no holotype existed, Bange (1952) proposed the specimen collected by Baeuerlen in 
October 1892 (BRI 11134) at Richmond River (New South Wales) as the lectotype for 
the variety 'because it is probably the specimen F. v. Muell. and Bailey have seen, the 
more so as the specimen is a good one'. Bange made no mention of the specimens 
collected in the same month in 1892 by Baeuerlen (No. 864) at Murwillumbah (MEL, 
NSW) as those at MEL were under the genus Geissois and he did not examine NSW 
material. It could be argued that the locality (Richmond River) of the designated 
lectotype does not fit Bailey's published habitat description of 'Towards Tweed River . 
However, Bailey gave that vague description in The Queensland Flora (1900) from a 
Queensland perspective and we do not consider it sufficient reason to overturn 
Bange's lectotypification. This taxon is not known to occur in Queensland, even 
though it has been found very close to the border with that State; Bange (op. cit.) 
erroneously cited a specimen collected at Chillingham ( Dixon s.n., BRI 101933) for 
Queensland. 
Common name: the common name widely used for this taxon is Davidson's Plum 
(Williams et al. 1984; Floyd 1989; Harden 1990).
