DESCRIPTION OK THE SPECIES. 305 



Only one specimen was fouiul. The leaf is too iniperf'ectly shown to 

 enable its character to be made out. It may be compared with Cclu.strus 

 Senegalensis. 



Celastrophyllum acutidens. 



riato CLVI, Fig. 8. 



Leaves small, narrowly-elliptical; leaf-substance comparatively thick; 

 margins with acute, shallow, and small teeth, that are curved forwards ; 

 midnerve proportionally quite strong ; lateral nerves very slender, going 

 off at an angle of about 45°, curving forwards and forking dichotoniously, 

 very poorly disclosed; reticulation not seen. 



Locality: 72d mile-post, near Brooke; very rai'e. 



This plant looks something like a Baitksia in its toothing and in the 

 shape of the leaf. 



Celastrophyllum obtusidens, sp. nov. 



Plate CLVI, Fig. 5. 



Leaves rather large, with a comjiaratively thick and firm leaf-substance, 

 apparently elliptical in shape, having on the margins of the leaves shallow, 

 obtusely-rounded teeth, turned outwards and very closely placed ; mid- 

 nerve proportionally quite thick ; primary nerves very slender, going off 

 obliquely and curving forwards, the bases only being seen ; ultimate ner- 

 vation not visible. 



Locality : 72d mile-post, near Brooke ; quite rare. 



This plant also resembles Banksia in the peculiar teeth and the very 

 slender primary nervation. The teeth have been accidentally removed, 

 except at the summit of the leaf It is close to C. acutidens, and may be a 

 variety of it. 



Celastrophyllum Brookense, sp. nov. 



Plate CLVni, Fig. «; Plate CLIX, Fig. 7. 



Leaves of medium size, varying considerably in dimensions, narrowed 



towards the base, so as to give them a wedge-shaped form, swelling rapidly 



out in the middle to a broad elliptical shape ; towards the summit narrowed 



rapidly and prolonged to a ijoint jirobaljly ; midnerve very distinct, lateral
