NOTES ON ACACIA. 97 



longitudinal veins and numerous finer veins parallel thereto, 

 the whole phyllode covered with minute resinous dots. 



Spikes slender, not very dense, attaining a length (as 

 measured by an almost glabrous rhachis) of 4 cm. (If inch). 

 Flowers 5-merous. Oalyx broadish, semi-truncate, with 

 ciliate edges to the lobes. Petals united a little way up or 

 free, glabrous. Pistil covered with a short tomentum. 



Pods (described from No. 25). Thin, translucent, straight, 

 5 cm. long, width 6 — 7 mm., abruptly and sharply pointed 

 at apex, somewhat abruptly tapering into a filiform pedicel 

 of about 5 mm. Margins of valves thickened, valves 

 embossed, the seeds arranged almost transversely. Punicle 

 filiform, terminating after two or three folds in a slightly 

 thickened arillus. 



Mueller's No. 93, Lower Victoria River, Northern Terri- 

 tory, is taken as the type, while Mueller's No. 25, from the 

 Roper River, is taken as the co-type. 



It is named in memory of my only son, Harrie Hammond 

 Maiden, who for years before his untimely death, was my 

 companion in the bush, and an assiduous observer and col- 

 lector of plants. 



Range. — Northern Territory (Arnhem's Land) and 

 Northern Queensland, extending across the tropical portions 

 of both political divisions. The Victoria River embouches 

 close to the Western Australian boundary, hence later I 

 expect to fiud the plant in tropical Western Australia; the 

 Roper runs into the western portion of the Gulf of Carpen- 

 taria. On the other (eastern) side of the Gulf, the Olon- 

 curry Road, Normanton, is towards the south-eastern angle 

 of the Gulf, while the Etheridge River is more to the east. 

 The Etheridge runs into the Einasleigh which runs into the 

 Gilbert, which flows into the eastern side of the Gulf. 

 Georgetown is the chief settlement on the Etheridge.
