Chenopodiaceae. 



Enchylaena villosa, F. v. M. Warramboo (Dist. L). 



Bassia Birchii, F. v. M. Minnipa (Dist. L). A small 

 undershrub about 20 cm. high; branches erect or spreading; 

 the fruits in the Minnipa specimens have six rather unequal 

 spreading spines, two of them connate towards the base and 

 with a ridge on the perianth between them. B. uni flora, 

 F. v. M. Murat Bay and north thereof. Stems procumbent, 

 Momentum hoary, fruit oblique at base with a very short 

 spine at one side of the summit and a hard tubercle at the 

 other. Agrees exactly with specimens gathered at Port Vin- 

 cent (Dist. Y). Of the form with fulvous tomentum I have 

 a, specimen from Port Lincoln (Dist. L; H. H. D. Griffith). 

 B. tricornis, F. v. M. Renmark. Bentham gives the number 

 of style-branches as three : in all the flowers examined I found 

 only two. 



Kochia decant era, F. v. M. A few miles north of Murat 

 Bay. An erect shrub about 1 m. high ; stem and branches 

 densely white-tomentose, as also the raised summit of the 

 fruit ; leaves linear, thick, green, 5-10 mm. long. Specimens 

 from Dublin (Dist. A; H. H. D. Griffith) have the horizontal 

 wing pink ; linear-ciavate glaucous leaves and tomentose stem 

 and branches. This probably represents Tate's K. pent a - 

 tropis, which he afterwards reduced to a form of A', decaptera. 

 Specimens from Arkaringa (Dist. C; Miss Staer) have the 

 stem and branches glabrous; leaves cylindrical, 10-13 mm. 

 long. In drying, all the leaves turn black. 



Threlkeldia diffusa, R. Br. Althorpe Island (Dist. Y; 

 S. A. White). Th. inchoata. This is the correct name of 

 Th. obliqua (these Transactions, xxxix.. p. 94), as it appears 

 imperative, under article 48 of the Vienna rules, to retain 

 the original specific name, even if somewhat inappropriate, 

 when a species is transferred to another genus. 



Atriplex paludosa, R. Br., var. appendiculata , Benth. 

 Both the type and the variety are found on Thevenard Penin- 

 sula. Flowers dioecious in my specimens and the small 

 bladdery appendage of the variety occurs near the base of 

 each valve (not of one only, as stated by Bentham), although 

 frequently one falls off before maturity. Some specimens of 

 A. vesicaria, Hew., brought by Captain White from the 

 Musgrave Ranges, show the same caducity of the appendage, 

 and unquestionably there is a close relation between the two 

 species. A. halimoides, Lindl. Goat Island (Dist. Y: S. A. 

 White); Telowie (Dist. N). A. campanulata, Benth. Berri ; 

 Mann Flat : Carrieton ; Gladstone : Moolooloo. This species 

 was united by Mueller with A. angulata, Benth., but in the
