Lincoln District, yet it is wanting in several of their salient 

 forms, such as species of GreviUea, Cryptandra, XantJiorrluea,'*' 

 various genera of Myrtacew^ Eucalyptus cory uocalyx, etc. 



Much of Soutliern Yorke-Peninsula is virgin-country, and 

 tliough sheep have been run all over it in past years, yet it is 

 fairly free from alien plant-species. The extra-Australasian 

 species number 31, or about IS-.j per cent, of the total species, 

 the same as for Kangaroo Island ; all the species occur in Kan- 

 garoo Island and at Port Lincoln. Some very wide-spread species 

 have not yet been observed, such as : — Hypericum Japonicutn^ 

 Stellaria gJauca, Lepidiuni ruderah, Solanuni nigrum, Lytlirum 

 hyssop/oHa, Luzida campestris, Juncus bufonius, AntJiistiria 

 ciliata and OpJiioglossum vulgafum. 



The only species whose presence is difficult to account for in 

 the present state of our knowledge of its distribution is Selxea 

 albidijiora, as its western limit was thought to be the Mount 

 Gambier District, where I found it in 1881. 



Acacia anceps is peculiar to the Port Lincoln district, and must 

 be very local, as I have not seen it in life there; in S. Yorke-' 

 Peninsula it is widely spread. 

 Isotoma scapigera extends from King George Sound to Fowler 

 Bay and Streaky Bay, and reaches its eastern limit in S. 

 Yorke-Peninsula. 

 CaUitris verrucosa in a varietal form occurs only between West 

 Cape and Cape Spencer. It is of a regular pyramidal form, 

 attaining to a height of about ten feet, fruiting, however, at 

 eighteen inches to two feet. The cones are slightly under 

 half-inch diameter, quite smooth and racemosely clustered 

 in groups up to five and six : the foliage is a bright green. 



"" An arborescent grass-tree is reported to occur five or six miles north of 

 YorketoMii ; but specimens have not yet reached me ; it is an addition to 

 District Y. Dr. James has forwarded me Thrypfomene Jlique/iana, 

 gathered by him in the scrub six miles from Moonta ; this is the first defi- 

 nite locality in 8. Austi'alia for it, the only record being " Spencer's Gulf," 

 on the authority of Warburton. Ca-ss/a Star til is another addition by the 

 same collector.
