E. tetrodonta (see Plate 185, this Part). The stamens are in four bundles, but 

 are disposed round the staminal ring , which is not undulate in this case. 



E. tetragona (see Plates 188, 189, Part XLVI). The stamens are in four bundles 

 on an undulating staminal ring, mth a distinct gap between the four clumps. This 

 species is especially interesting because it is that on which the genus Exdesmia was 

 founded. 



E. eudesmioides (see Plate 189, Part XLVI). The stamens are in four bundles 

 on an undulating shallow staminal ring. There is a gap without stamens between 

 each pair of bundles. 



As regards E. tetragona and E. eudesmioides, the stamens appear to have thinned 

 out or disappeared where the staminal ring becomes narrowest at the troughs. Speaking 

 generally, as regards the Eudesmiese, whether the ring is of varying thickness or not, 

 the stamens appear to thin out at four parts of the periphery. 



E. Baileyana (see Plate 182, Part XLIV, where, however, the stamens are not 

 shown in the mass). The stamens are in four distinct bundles right roimd the staminal 

 ring, although more deciduous between the bundles. 



RANGE. 



It is confined to Western Australia. The type was collected " at the Murchison 

 River, towards Shark's Bay, in rocky plains," by Oldfield. 



In " Eucalyptographia " its range is defined as "In stony undulating bushy 

 country between the Irwin River and Shark Bay, rather rare." " Not observed nearer 

 (to Shark's Bay) than 20 miles south of Freycinet Harbour. The plants indigenous 

 around Shark's Bay and its vicinity." (Mueller, Parliamentary Paper, W.A., 1883, 

 p. 14.) 



. This would bring it not many miles north of the Murchison River, and it would 

 be desirable to enquire into its limits more accurately, which are at present recorded 

 as 10 miles south of Dongarra (which is at the mouth of the Irwin River) on the Arrow- 

 smith road in the south, and 20 miles south of the Freycinet estuary in the north. We 

 do not know its eastern boundary. If Drummond's Dundaragan be identified, as it 

 seems to be, with the modern Dandaraga, then the southern boundary is removed to 

 say, the Moora district, Moora being a railway station 108 miles north of Perth. It 

 would be very desirable to obtain more accurate information in regard to the range 

 of one of the most interesting species of the genus. 



I have seen specimens of Drummond's No. 70 (6th Coll.) in Herb. Calcutta and 

 Herb. Cant. " Limestone Hills, west of the Valley of the Lake," which is, of course, 

 near Dundaragan, as already quoted from Drummond's original letter. This place 

 has been already referred to. I have also seen it from the Murchison River, in Herb. 

 Barbey-Boissier, collected by Oldfield.
