C. H. Ostenfeld: Contributions to West Australian Botany. II. 51 



Specimens examined: Carnarvon, common in dune depres- 

 sions: Diels 190 L (No. 3722, herb. Berol.); Dr. I. B. Cleland (ex 

 herb. Mus. Perth); C. H. Ostenfeld (No. 1101, 31. Oct. 1914). In 

 arenosis exsicc. inter Restiones ad ripam fluvii Cygnorum prope 

 Peninsulam, Herb. Preiss No. 1283. 



A coarser, nearly erect form has the same floral characters, 

 but has larger (broader and thicker) calyx and shorter, thicker- 

 leaves (only 3—5 mm long) ; this is, probably, the original form 

 described by De Candolle. It is present in Herb. Berol: (1) Nova 

 Hollandia, Cote occid. Ex Museo Paris 1819, Hb. Kuntze. (2) Inneres 

 West-Australien, Murrin-Murrin, W. J.George 1902, comm. L. Diels. 



2. Frankenia serpyllifolia Lindley, in Mitchel, Trop. Austr. 

 (1848) 305; F. pauciflora, var. serpyllifolia Benth., Fl. Austr. I 

 (1863) 152. 



An erect much branched shrub (20 cm high) with elongated 

 densely pubescent internodes and divaricate dichotomous cymes 

 (Fig. 15). Leaves short and broad, especially the lower, broadly 

 ovate to linear-ovate (the floral ones), with revolute margins (but 

 not so much as in other species), glabrous on both surfaces. 

 Flowers smaller than in F. pauciflora ; calyx hairy. Floral charac- 

 ters otherwise as in F. pauciflora (several ovules etc.). 



In Herb. Berol. a specimen presented by the late F. v. Müller 

 and labelled »West Austr.« has been named F. serpyllifolia by 

 Bray j ), and I think with good reason. It is near F. pauciflora, 

 but the differences in the vegetative parts are so great that I 

 think it a good species. 



3. Frankenia conferta Diels, in Diels et Pritzel, Fragm. Phytogr. 

 Austr. occ, Botan. Jahrb. 35 (1904) 389. 



I have seen part of the type specimen (in Herb. Berol.) and 

 refer to Diels' exhaustive description. No doubt it is near to 

 F. pauciflora, the floral characters of which are the same. 



4. F. Drummondii Benth. in Fl. Austr. I (1863) 152. 



I have not seen any specimens of this species, and have 

 placed it in the key according to the description. 



5. F. ambita Ostf., see above p. 24 (Fig. 9). 



Seems to be restricted to the north-western part of the state.
