rugose-alveolate in the lower part. [Often met with along 

 the Cooper : 6 to 10 inches tall.] 



Umbelliferae. 



Didiscus glavcifolivs, F. v. M. Tinga-tingana [Found 

 growing in the bed of the creek in damp sand.] 



CONVOLVULACEAE. 



Convolvulus erubescens, Sims. Mount Lyndhurst. 

 [Found growing in centre of bushes ; otherwise it would be 

 exterminated by stock.] 



BORRAGINACEAE. 



Trichodesma Zeylanicum , R. Br. Between Innamincka 

 and Kanowana. [Not a common plant; only seen once or 

 twice ; the larger plants were from 18 inches to 2 feet high.] 



Echinospermum concavum, F. v. M. Lake Perigundi. 

 [There was a quantity of this bush round the edge of the 

 sand at high-water mark ; it was about a foot high, and 

 stuck to the clothing when we passed through it.] 



Verbenaceae. 



Dicrastylis CosteUoi, F. M. Bailey (pi. xlii.). Lake 

 Perigundi. One of Capt. White's specimens was forwarded 

 to Mr. C T. White, Acting Government Botanist of Queens- 

 land, who considers, after comparison with the types, that it 

 differs from D. CosteUoi, especially as regards the clothing of 

 the plant. It is quite true that the clothing of our speci- 

 mens is looser and more woolly, especially on the branches, 

 but desert plants vary so much in this respect, and the flowers 

 are so exactly alike, that I have placed them, at least pro- 

 visionally, under the name quoted above. The plate shows 

 a drawing and details of a small type-specimen kindly given 

 me by Mr. White, also one of the specimens from Lake Peri- 

 gundi, and also one from Lake Eyre, preserved (under the 

 name D. Beveridgei), in the Schomburg Herbarium, which 

 is remarkably like the Queensland type. It is quite possible 

 that B. CosteUoi may ultimately have to be reduced to a 

 white-flowered variety of T) . Beveridgei, F. v. M. Our speci- 

 mens of the latter from Ooldea seem to differ only in the 

 golden tomentum of the flowers, and in the leaves darker 

 above, owing to some of the hairs wearing off. [Some good- 

 sized bushes were met with near Lake Perigundi, and attracted 

 attention by the very light colouration of leaves, flowers, and 

 stems. Grew from 18 inches to 2 feet high.]
