important point the description is erroneous, viz. the number of 

 ovules is not several ("ovula plura"), but only two, as in the 

 preceding species. No doubt Preiss's plant is very near his two 

 other species, and the only reason for placing T. intricata under the 

 subgen. Bulliarda (while the two others are placed under Tillæa 

 proper) was the supposed differences in the number of ovules, 

 and this is wrong. 



Near the Ya HingupCaveHousel collected a Crassula on sandy 

 open places (No. 360, 26. Aug. 1914) which is identical with Preiss's 

 plant, and my richer material allows me a fuller conception of 

 the species, which is, in reality, very close to C. colorata. The 

 main differences are the quite different habit, owing to the de- 

 cumbent and rich branching, the solitary or few flowers in the 

 axils, and the recurved beak of the fruiting carpels. A short 

 description runs as follows: 



A much branched annual with decumbent bases of the stem 

 and branches, and ascending upper parts, 2 — 5 cm high. Leaves suc- 

 culent, ovate-oblong, obtuse, 2 — 3 mm long. Flowers axillary, 

 solitary or in few-flowered clusters, sessile or nearly so, 5-merous, 

 forming long interrupted spike-like inflorescences. Sepals broadly 

 ovate, acute-acuminate; petals linear-lanceolate, acuminate, as 

 long as or a little longer than the sepals. Stamens somewhat 

 shorter. Carpels, when ripe, much exceeding the -sepals, oblong- 

 ovate, acute, tapering evenly into a recurved beak; seeds two in 

 each carpel, brown. Nectary scales minute, linear-clavate. 



The species seems to belong to the coastal area and may be 

 a coastal vicarious species for C. colorata. Hitherto known only 

 from Rottnest Island off Freemantle and Yallingup Gave House. 



There are two more species of Crassula recorded for W. 

 Australia, viz. C. bonariensis Cambes (= Tillæa purpurata Hook, f.) 

 and C. recurva (Hook, f.) ; but whether these records are correct 

 or not, I do not know, as I have not seen Drummond's plants, 

 among which they are found (according to Bentham, 1. c. 452). 

 I have included them in the key to the W. Australian species of 

 Crassula given above (see p. 39). In the Eastern states there are 

 further C. Sieberiana (Schultes), mentioned above, and the newly 

 described Victorian species C. (Tillæa) exserta (F. M. Reader in 

 Vict. Naturalist XIV, p. 83) which I have not seen. 



III. Frankenia. 



The Frankenias of West Australia are rather difficult to ex- 

 tricate. The treatments by the different authors (Turczaninow,
