I'HE PLANTS OF THE ENCOUNTER BAY DISTRICT. 
Bv J. Burton Cleland and J. M. Black. 
One of us (J. B. C.), having spent various holidays at En- 
counter Bay, determined to collect as far as possible all the plants 
of this locality. To ensure accuracy his determinations have 
been checked by the other of us (J. M. B.) or the unindentified 
plants have been determined. Mr. J. H. Maiden has seen and 
identified specimens of all the Eucalypts, whilst Dr. R. S. Rogers 
has identified or confirmed the orchids and has added personal 
records of his own. The area embraced in this survey extends 
from Middleton on the east to Tunkalilla Reach and Road, more 
than halfway between Encounter Bay and C. Jervis, on the west. 
The Inman Valley to the Bald Hills is included, as well as the 
Upper Waterfall in the Hiridmarsh Valley, within two miles of 
Hindmarsh Tiers School. The Mount Compass and Myponea 
districts are excluded. Occasional records of plants In adjacent 
areas are included in heavy brackets 
To make the list complete, plants previoush' recorded for the 
district, but not collected by us, have been included. These are 
few in number (about 21) and such previous record is indicated. 
In Dr. Rogers^ list of orchids are a further 20 species which 
we have not yet collected ourselves. The total number of plants 
in this list is approximately 603 (excluding 10 varieties), of which 
about 100 (104) are introduced species (indicated b\^ before 
the name). 'Fhe surve}' has resulted in the finding of an orchid 
new to science (Microtis sp.), to be named by Dr. Rogers, <me 
species (Schoe?ius fluitans) new for the mainland, and one of us 
(J. M. B.) has named one new variety (Cyperus Kragrotis var. 
pauperata). Daviesia pectivaia, a Port Lincoln plant, was found 
at Waitpinga. Pultenaea teretijolia, another Eyre Peninsula 
plant, was also collected here for the first time. Kucalyptus 
cneorifolia, the Kangaroo Island oil-mallee, given b\' ATaiden for 
Kangaroo Island only, was met with. Correa reftexa was found 
at Waitpinga sufficiently early to be included in Black’s ‘‘Flora 
of South Australia.” The Porcupine Grass (Triodia irritans) was 
noticed at Waitpinga, a considerable distance from other known 
occurrences. It is hoped that later this list may be supplemented 
by some ecological notes.
