Aizoaceæ. 



Trianthema crystallinum Vahl, Symbol. I (1790) 32 et in D. C. 

 Prodr. III, 352; Benth. FL Austr. III (1866) 330. 



Of this variable species (or aggregate of species) a form with 

 long, linear, semiterete leaves was found along the jetty at Derby 

 (No. 1173, 7. Nov. 1914). Another form was collected in a dune 

 depression at Port Hedland (No. 1152, 3. Nov. 1914); it has 

 oblong-linear succulent leaves. (Both determined by Dr. 0. Paulsen). 



Trianthema turgidifolium F. v. Müll., Fragm. Phytogr. Austr. 

 X (1876) 83. 



This interesting succulent species was well described by F. 

 v. Müller (1. c.) upon specimens collected "in plagis sinum Nichol's 

 Bay versus" by M. Crouch. From the same area, 

 Point Samson (near Cossack) I have brought 

 home specimens (No. 1153, 2. Nov. 1914) which 

 agree well with Mtiller's description. 1 The leaves 

 are very succulent, globose-clavate, downwards 

 attenuated into a short petiole (see Fig. 4). The 

 flower is whitish, sepals long-triangular, acute, 

 stamens 10 with red-brown anthers, ovary nearly 

 globose with one somewhat excentric filiform style ; 

 the membranous capsule contains several seeds 

 (somewhat more than "circiter 5", as F. v. Müller 

 says). 



The species has, as pointed out by F. v. Müller, 

 a striking resemblance to small-leaved succulent 

 forms of Sesuvium portulacaslrum, and I must 

 admit that I think the two genera ought to be 

 united, or Trianthema split up into several genera; 

 the present delimitation at least is very arti- 

 ficial and unsatisfactory. 

 T. turgidifolium was found inside the mangrove in a salt-pan 

 together with Frankeniæ and Salicorniæ. 



In F. v. Muller's 2nd Census (p. 52) the species is given for 

 S. A., Q. and N. A., not for W. A., but there must be some mis- 

 take here (printer's error ?) as Nichols Bay is in W. A., and it is 

 doubtful if the species has been recorded from other states.
