Port Hedland, in low-lying parts of sand-dunes near the 

 shore, partly buried by sand (No. 1156, 3. Nov. 1914). 



Verbenaceæ. 



Avicennia officinalis L. Sp. pi. (1753) 110; Benth. Fl. Austr. V 

 (1870) 69; R. T. Baker, in Journ. & Proe, R. Soc. of N. S. Wales, 

 XLIX (1916) 257. 



Point Samson (Cossack), with young flower buds, very 

 common in the mangrove (No. 1148, 2. Nov. 1914). 



Port Hed land, common (3. Nov. 1914); see PI. I, figs. 2—3. 



Broome, common (5. Nov. 1914). 



Derby, with young flower buds, very common in the man- 

 grove (No. 1167, 7. Nov. 1914); see PI. I, fig. 1. 



This is the main component of the W. Australian mangrove. 

 It is called "white mangrove" or "grey mangrove". As pointed 

 out by R. T. Baker in his recent monograph of "the Australian 

 Grey Mangrove" the name A. officinalis L. covers a great variety 

 of forms. 



Myoporaceæ. 



Myoporum acuminatum R. Br., Prodr. Fl. Nov. Holl. (1810) 515; 

 Benth. Fl. Austr. V (1870) 3. 



Point Samson (Cossack), a bright-green shrub with white 

 flowers and purple drupes; near the shore (No. 1132, 2. Nov. 1914). 



I follow Bentham (1. c.) in his treatment of the many closely 

 allied forms of Myoporum. The specimens collected answer well 

 to his var. angustifolium Benth. (1. c. 4) = M. Cunninghamii Benth. 

 in Hügel, Enum. (1837) 78, which latter name ought to be used 

 as it has the priority. 



Goodeniaceæ. 



Scævola sericopkylla F. v. Müll., in Bentham, Fl. Austr. IV 

 (1869) 102; K. Krause, Goodeniaceæ in Das Pflanzenreich IV. 277 

 (1912) 162. 



Point Samson (Cossack) (No. 1154, 2. Nov. 1914). 



A shrub with unarmed rather long branches and dwarfy 

 rosulate side-branches bearing silver-clothed leaves and the in- 

 conspicuous white flowers. It was the dominating species in a 

 sparsely covered sand-dune area near the jetty. 



Compositæ. 



Pterocaulou sphacelatus (Labill.) Benth. et Hook. Gen. pi. II 

 (1873) 94; F. v. Müll. Sec. Census (1889) 134; Monenteles sphace-
