numerous; the specimen from Burswood Island, W.A. has 

 as many as 20, and in our South Australian coastal specimens 

 the number of articles in the spike runs up to 30 and 40. The 

 fruit, seed, and the number of bisexual flowers in each triad 

 are quite different in the two species. In Nees' type specimen 

 (Preiss, No. 1910) the seeds, although not quite ripe, show 

 distinctly the characteristic markings of the testa. 



For an explanation of what I believe is the confusion of 

 two species in Bentham's Salicornia tenuis see below under 

 Pachycornia tenuis. 



Var. pergranulatum, n. var. (Tab. xxxiii.) A typo 

 variat semine orbiculari-reniformi circiter 1 mm. diametro, 

 testa brunneo-rubra omnino subconcentrice granulata. 



S. Australia. Salt lands near the Grange and at 

 Birkenhead (Port Adelaide River, J. M. B., Jan. -May, 1919); 

 Noarlunga (J. M. B., Jan., 1905) ; River Frome, near Marree 

 (J. M. B., October, 1917); between Port Elliot and Victor 

 Harbour (H. W. Andrew, Feb., 1919); Mann Crossing, River 

 Murray (H. W. Andrew, Nov., 1915); Lake Hart (Dr. G. 

 Taylor, May, 1919); Cootanoorinna (near Warrina, R. Helms, 

 in Tate Herbarium as Salicornia leiostachya, May, 1891). 



Queensland. Port Alma, C.Q. (L. Hassell, in Queensland 

 Herbarium as S. leiostachya, October, 1917). 



The variety differs from the type in its seed, which is 

 orbicular-reniform, reddish-brown and granular all over. It 

 is usually a lower shrub, more spreading, and 30-50 cm. high. 

 In the specimens from Frome River and Port Alma the 

 position of the pericarp in the perianth is almost horizontal, 

 instead of oblique, and although some of the seeds are ripe, 

 the perianths have not separated -from the article, and the 

 membranous pericarp adheres more or less to the seed. The 

 greater or lesser obliquity of the fruit does not seem to be 

 of much importance, for in the Cootanoorinna specimen the 

 pericarp is horizontal, but the perianths are falling from the 

 spike. The seeds bear considerable resemblance to those of 

 Silene, Calandrinia, and Mesembryanthemum . 



2. A. Lylei, (Ewart et White) combin. nov. (Tab. 

 xxxiv.) Haec species distat ab A. halocnemoidi pericarpio 

 mamilliformi apice crustaceo horizontaliter prominente atque

 Salicornia Lylei, Ewart et White in Jour. Roy. Soc, N.S. 

 Wales, xlii., 195, t. 34 (1908). 



A very distinct species by reason of its ovoid pericarp, 

 which is membranous except near the summit, where it 

 becomes crustaceous and is produced in a nipple-like point 

 (the persistant style) beyond the 3 broad lobes of the perianth ;
