Capsule tridymous, furrowed, sprinkled with stellate scales ; 

 about 3 lines long and 6 lines broad ; slightly depressed at the top. 



Hah. — Banks of a rocky creek, near Tintenbar, Richmond 

 River, New South Wales ( W. Biiuerlen). 



This species is most closely related to two Queensland species, 

 C. acronychioides and C. triacros, and is quite distinct from any 

 New South Wales Groton. 



It differs from C. acronychioides and C. triacros in the texture 

 of its leaves, which are thin ; the pedicels are also much longer. 

 In regard to the number of stamens, it has usually 5, and appa- 

 rently never more than 6, while G. acronychioides may have as 

 many as 8, and C triacros as many as 10. 



The stamens of G. acronychioides are longer than those of our 

 species. 



In the Flora Australiensis there is no reference to petals in 

 either G. acronychioides or G. triacros, but in our species they are 

 marked. 



The persistent calyx under the fruit is also to be noted, as 

 among Australian Grotons it appears only to be present in G. 

 opponens. 



The capsule of G. acronychioides is described as " longer than 

 broad, scarcely furrowed." The dimensions given above for the 

 capsule of our new species will show that such a description does 

 not apply to its fruit. As a matter of fact, the fruit of our species 

 is both furrowed and deeply lobed, in which respect it resembles 

 that of G. triacros. 



ABBREVIATED ANALYSIS. 



C. acronychioides. — Leaves coriaceous. Stamens 5 to 8. Capsule 



longer than hroad, scarcely furrowed. 

 G. n.sp. — Leaves thin. Stamens 5, rarely 6. Capsule broader 



than long, 3-lobed and furrowed. 

 G. triacros. — Leaves coriaceous. Stamens about 10. Capsule 



deeply 3-lobed at the top and 3-furrowed.
