NOTES AND EXHIBITS. 395 



over a month had suffered no deterioration. Tested by Nuttall's 

 method, no alteration could be detected when the dried antiserum 

 was tested against fluid antiserum. 



Mr. Fred. Turner exhibited, and offered some observations on, 

 fifteen species of Acacia collected in the Dubbo district, where 

 they were flowering during August and September, viz., 



PHYLLODINEiE. 



Acacia t^'iptera Benth. — This rigid shrub has pungent-pointed, 

 prominently nerved phyllodes. It sometimes grows in dense 

 masses which are most difficult to penetrate. 



A. colletioides A. Ounn., is a rigid shrub, with rather remarkable 

 almost linear-terete, many finely-nerved phyllodes. It usually 

 grows on good land. 



A. conferta A. Cunm, is a tall-growing species with very small 

 linear phyllodes, which are crowded on the branches. It flowers 

 most profusely. 



A. lineata A. Cunn., attains sometimes a height of ten feet, 

 with usually pubescent branches and small linear hairy phyllodes. 

 It is a pretty sight when in bloom. 



A. penninervis Sieb. — The phyllodes of this rather tall tree are 

 most variable as regards size. Sometimes they are only from two 

 to three inches long, at other times from six to eight or more 

 inches long. This species may be recognised, even when not in 

 flower, by its more or less prominently finely penniveined 

 phyllodes, and by its secondary nerve when present terminating 

 in a marginal gland. 



A. notahilis F.v.M. — This is a nota,ble and handsome species, 

 sometimes growing into a small tree and producing globular, 

 comparatively large heads of flowers. It is fairly common. 



A. hakeoides A. Cunn., is a tall and very floriferous shrub. It 

 is fairly plentiful, growing on both good and inferior country. 



A. decora Reichb., although flowering profusely as a dwarf 

 shrub, sometimes grows several feet high, and is a very pretty 

 sight when in bloom. It is fairly common.
