Since 1870, the year when Vol. V of Bentham's Flora ap- peared, no original treatment of Australian Salicornieæ has been published. Only some of Bentham's species have been given generic rank by Hooker (Teclicornia, Pachycornia) who adds "analysis florum ob mollitiem organorum difficillima". It is true that it is a difficult tribe, and it seems to be disliked by systema- tists. In trying to identify the species collected by Dr. Ostenfeld I have been able to compare them with Australian specimens, from the Berlin Museum, kindly placed at my disposal by Pro- fessor Diels. For the rest, no material was at hand for com- parison, so I had to name the plants mostly after descriptions. Allthough some of the species are not known to belong to the genus named above, they are enumerated here; when their seeds become known they may, if needed, be removed to other genera. 20. A. Arbuscula (R. Br.) Moq., Chen. mon. enum. (1840) 113; D. G. Prodr. XIII 2 (1849) 152; Salicornia arbuscula R. Br. Prodr. (1810) 411 ; Benth. Fl. Austr. V (1870) 203. (PI. VI, fig. 1). A shrub forming do- me-like cushions. Spikes short; the fruiting peri- anths are horizontally emerging, free, and den- tate above (Fig. 23). Peri- carp thin and membra- naceous, radicle below, al- bumen lateral and embryo curved. Fruiting, only No. 330 not, this was apparently dying. Kalgoorlie (No. 330, 7. Oct. 1914); Carnarvon (No. 351, 31. Oct. 1914); Port Hedland, in dune pans (No. 1142, 3. Nov. 1914). 21. A. lciostachyum (Benth.) comb, nov.; Salicornia leiostachya Benth. Fl. Austr. V (1870) 203. (PI. V., fig. 2). Shrubby, articles thickened upwards, shortly and bluntly bidentate, with scarious margins. Even between the nodes bearing ripe spikes the internodes are still covered by assimilatory Fig. 23. Arthrocnemum Arbuscula. a, ripe perianths with seeds, b, s
