A detour among the sandhills was now made, wlien Mr. J. 

 O. 0. Tepper, F L.S., explained their formation and the fixing 

 of the loose sand by the roots of various peculiar plants, such 

 us Spinifex hirsutus — (the "Spinifex" of explorers is a grass, 

 Triodia irritans) — Scirpus nodosus, Lepidosperma gladiatura, 

 Aster axillaris, Styphelia australis, Kunzea pomifera, Myopo- 

 rum parvifolia, &c., all of which were indicated. Other 

 plants collected were Banksia marginata, Calocephalus 

 Browni, Tetragonia implexicome, Atriplex cinerius, and Sali- 

 •cornia australis. Attention was directed to the uniform 

 «lope of the sheaoaks, indicating the prevalence of south- 

 west winds. 



Teis^th Excuesiox — Mo^^DAY, September 1, 1884. 



Thirty members started at 8.30 a.m. per special coach for 

 •Clarendon. The morning promised fair weather, but a heavy 

 shower on arrival and the prospect of more to follow made it 

 unadvisable to proceed, as was contemplated, to the botanically 

 rich scrublands between Clarendon and Kangarilla. It was 

 therefore decided to inspect and examine the river scenery 

 along the Onkaparinga, east of the bridge, instead. After 

 lunch a meeting was held, presided over by Mr. J. Gr. O. 

 Tepper, F.L.S., at which one new member was elected ; and 

 then the members proceeded up the right bank under the guid- 

 ance of Mr Tepper and Dr. Schmid. At the first bend it was 

 observed that all the pines peculiar to the valley of the river 

 — Callitris cupressiformis — had been cut down, and thereby 

 the beauty and interest of the place much marred. 



Attention M'as directed to the unequal denuding action of 

 the atmosphere upon the alternating texture of the rocks, viz., 

 micaceous and talcose shales and quartzites. The following 

 were the more remarkable plants gathered (mostly in flower), 

 the names of which, with a running commentary, were fur- 

 nished by Mr. Tepper: — Styphelia virgata, serrulata, australis, 

 fasciculiflora, Callistemon saliguus, Melaleuca decussata, 

 Accacia melanoxylon (the Blackwood, occasionally overloaded 

 by the parasitic Loranthus linophyllus or Preissii), verniciflua, 

 retinodes and obliqua, Auguillaria dioica. Cassia vittata, Cym- 

 bonotus Lawsouianus, Microseris Forsteri, Spyridium micro- 

 carpum, Correa decumbens, Adriana quadridentata (female 

 flowers just opening, male blossoms still immature), Grlycine 

 clandestiua, Kennedya j^rostrata and monophylla, Hibbertia 

 stricta, acicularis and fascicularis, Logania loDgifolia, Mesem- 

 brianthemum aequilaterale (depending in long festoons from 

 :Some of the inacessible rockwalls), and Cassytha melautha, 

 which spread over Avhole shrubs in an intricate network of
