[Read October 2, 18S8.] 



A hurried excursion, occupying a few days in the early part of 

 NoA'ember, 1887, in tlie Port Lincohi district, brought to my 

 knowledge the occurrence of 51 species not hitherto known there. 

 The country traversed is well within the wettest part, and is 

 therefore the most typical portion of the phytographic district of 

 Southern Eyre Peninsula. The route was from Port Lincoln by 

 way of Little Swamp, tlie Fountain, to Lake Wangary, to Marble 

 Range, to Kellidie Bay (an extension of Coffin Bay), to Straw- 

 berry and Winter's Hills on the west slope of the coast range, 

 which extends north from Port Lincoln, and back to the seaport. 

 The leading physical features are — 



1. The coast range, consisting of metamorphic rocks, is 

 clothed with open forests of Casuarina, and Eucalypts according 

 to the nature of the soil. 



2. A low depressed "area, to the west, extends to the coast 

 line on the south-west, and is interrupted on the north-west by 

 isolated peaks of metamorphic rocks, as Marble Range (a mis- 

 nomer, as the rock is a hard highly metamorphic quartzite), 

 North Block, «tc. Towards the sea-coast much of this depressed 

 country is occupied by swamps, whilst the relatively high ground, 

 or rises, constitutes heath lands, or grass lands interspersed with 

 thickets and light timber, particularly of Eucalyptus corynocalyx. 

 Ranunculus aquatilis. Swamps at Little Swamp and near 



Kellidie Bay. 



Ranunculus lappaceus. Thickets near Fountain.

 This new species is a low diffuse under-shrub, with the

 reduced cyme, only one or two flowers as a rule being 

 developed."
