the acliene have small hooked branches near their extremities, 

 and the hairs on the outer face have the faculty of coiling. 



Angianthus brachy pappus, F. v. M. Ooldea, half-mile 

 west of the siding and on the edge of the Nullarbor Plain 

 (Dist. W; J. M. B.). My field note says: "Plant with 

 prostrate stems and short ascending branches; leaves rather 

 thick, compressed horizontally; compound heads conical, 

 yellowish, the vertical rows of partial heads usually twisted 

 spirally as flowering proceeds." In comparing this species 

 with A. tomentosus, Wendl., it should be noted that while 

 the latter has 2 conduplicate and 2 inner flat sessile 

 bracts to each partial head, A. brachypappus has 3 outer 

 bracts, subherbaceous and rigid in the lower half and placed 

 on the lower or outer side of the partial head, and 1 flat 

 sessile hyaline bract, after which come the 2 lateral con- 

 duplicate bracts and 2 inner clawed flat bracts, or 8 bracts 

 in all to each partial head. The anthers have no tails. This 

 species is recorded in Tate's Flora only for his S district, and 

 in these Trans, iv., 107 (1882), he gives the localities as 

 Kanyaka, Wonoka, and Edeowie, but there is no specimen 

 in the Tate Herbarium. In the Flora Australiensis the only 

 locality given for South Australia is "North-West interior, 

 MacDouall Stuart's Expedition." The name does not appear 

 in either of Mueller's lists of the plants collected on that 

 expedition, but the site was probably near the MacDonnell 

 Ranges, N.T. Mueller (Report Babbage's Expedition, 13) 

 gives for this species the locality of Stuart Creek; D. Her- 

 golt, collector. This creek is a little south-west of Lake Eyre 

 and in Tate's Dist. C. 



Gnephosis shirrophora, Benth. Ooldea (Dist. W; 

 J. M. B.). 



Helichrysum Lawrencella, F. v. M., var. Davenportii, 

 Benth. Specimens collected by me at Ooldea have ripe achenes 

 distinctly beaked and varying from pubescent to scabrous 

 with short stiff hairs, most of which wear off in time. The 

 pappus bristles of the outer fertile flowers are forked, some- 

 times twice, plumose from the base but merely barbellate 

 towards the summit; those of the inner sterile flowers are 

 similarly plumose and barbellate, but are not branched. 



H. MeMorianum, J. M. Black. East- West Railway, 407- 

 mile Station, near Ooldea. The number of heads in the 

 cluster varies from 4 to 12. 



Helipterum roseum, (Hook.) Benth., var. patens (Ewart), 

 combin. nov. Variat parvitate omnium partium plantae, 

 caulibus circiter 8 cm. longis, involucri bractearum intimarum 

 laminis albis tantum 4-5 mm. longis ovatis potius quam 

 lanceolatis.
