DESCRIPTION. 



LXIV. E. Baueriana, Schauer. 



In Walp. Bepert. ii, 924 ; Suppl. i, 1843. 

 Following is the original description : — 



Ramulis patentib. subfastigiatis teretib. ; foil, coriaceis ovatis v. subrhombeo-ovatis, basi obliqua in 

 petiolum longum contractis attenuatisve tenuiter acuminatis, margine cartilagineo subrevolutis undulatisq. 

 subglaucescentib. impunctatis reticulatis ; umbellis 5-7 floris axillarib. terminalibq. subpaniculatis ; 

 pedunculis subteretib. petiolo triplo breviorib. ; pedicellis subangulatis cupulae turbinatae continuis eamq. 

 subaequantibus ; operculo subconico-hernisphaerico apiculato cupula triente breviore. — Foliorum lamina 

 2-2j poll, longa, 1-2 poll, lata, petiolus pollicaris, pedunculus 3-4 lin. metiens ; cupula cum pedicello 

 3J lineam longa. — In Nova Hollandia legit F. Bauer. 



The type is in the Vienna Herbarium (Herb. Musei Caesarei Palatini Vindo- 

 bonensis). It is in plump bud and expanded flower. It bears a label, in Schauer's 

 handwriting, " Eucalyptus Baueriana, Schauer, in Walp. Repert." 



Access to the type has enabled me to settle the identity of Schauer's plant. 

 Collected by Ferdinand Bauer, it was doubtless obtained in the Port Jackson 

 district ; and it is the Lignum- vitas or Poplar-leaved Box, which was always looked 

 upon by Mueller as a form of E. polyanthemos, Schauer, and which, later on, was, 

 as will be indicated presently, recognised as a distinct species. 



Bentham (B.P1. iii, 214, under E. polyanthemos) says : — " The tropical 

 specimens to which, from the character given, belongs E. Baueriana, Schau., in 

 Walp. Rep. ii, 924, have generally smaller flowers and fruits than the southern 

 ones, but do not otherwise differ." Bentham is probably referring to certain 

 tropical specimens he thinks are referable to E. Baueriana, which were collected 

 by Bauer near the Gulf of Carpentaria, and which are E. alba. Walpers does not 

 say that E. Baueriana was collected in the tropics. 



Mueller (Eucalyptographia, under E. polyanthema) says : — " Bentham unites 

 with this \polyanthema~] E. Baueriana, Schauer, the diagnosis of which agrees 



sufficiently [with polyanthema] Bauer most probably obtained his 



specimens from the vicinity of Sydney, and not from the tropical regions of 

 Australia." I understand that Mueller never saw a type specimen of E. Baueriana, 

 Schauer. 



E. Baueriana, Miquel (Ned. Kruidk. Arch, iv, 137), collected by Charles 

 Stuart in Tasmania, is E. Gunnii, Hook, f., var. acervula. 



E. Baueriana, Schauer, may be described in the following words : — 



A tree of medium size,with rough dark bark on the trunk and ultimate branchlets. With a rounded 

 head of dense foliage. 



Juvenile leaves from nearly orbicular to broadly lanceolate in shape, dark green on both sides, 

 thin, margin undulate, the intramarginal vein at a very considerable distance from the edge, venation 

 almost triplinerved at the base, distant from each other, and spreading.
