134 DE. r. MUELLER ON AUSTRALIAN ACACIA. 



inter semina valde contracta, loculis vix ^" latis. Semina longitudi- 

 nalia subolivacea ovata leviter compressa 2^'" longa utrinque areolato-

 Speciminum tropicorum leguraina nondum vidi, conveniunt aiitem cum 

 aliis ab equite Mitchell in Australia orientali extratropica collectis.

 duligeris, pedunculis axillaribus solitariis monocephalis phyllodio 

 pluries brevioribus, leguminibus stipitatis subcoriaceis compressis 

 oblongo-linearibus angustissime alatis inter semina plus minusve con-

 pressis nitidulo-nigris, areolis non impressis.

[Dr. Mueller's specimens are in fruit. Col. Mitchell's in flower ; but 

 they appear to belong to the same species. The phyllodia are precisely 

 the same, so is the inflorescence ; for in Dr. Mueller's specimen the 

 peduncles are not always solitary. Col. Mitchell notes that it is a large 

 forest tree, Dr. Mueller found it a small tree ; but that might depend 

 upon locality. — G. B.]
