224 PROCEEDINGS OF SECTION D. 



Bursaria and Citriobatiis have spinescent branches. Pungent 

 pointed leaves are found in several Daviesias, some Acacias, Mir- 

 belia and Oxylobium trilobatum, the terete leaved Hakeas, Lambertia, 

 Xylomelum (on the young leaves), and most of the Epacrideae. 



Tannin filled cells are frequently found in the Proteaceae and 

 Leguminosae, particularly in the Acacias. 



In the first-mentioned order it is usual to find the outer epi- 

 dermal cells filled with this substance.-^ Henslow says it has been 

 suggested that tannin is hygroscopic.^ The presence of ethereal 

 oils is well known in the Rutacese, Myrtacese, some of the Labiatae 

 and the Coniferae. Henslow points out that desert plants are 

 notoriously aromatic, and mentions the suggestion that as a screen 

 of vapour from ethereal oil is opaque to heat rays, the secretion of 

 these oils may be of service to dry climate plants. 



The only Hawkesbury plants secreting hygroscopic substances 

 are the Chenopodiaceae.
