18th December, 1831, and named it on the following day; though 

 after whom he named it is not stated. On this journey, he followed 

 tlie right bank of the Namoi River, and also of the lagoon or billa- 

 bong, just east of Boggabri. Mitchell clearly shows that Namoi, 

 which he spelt "Nammoy," is the native name of the river below 

 the junction of the Conadilly. Special mention is made of a 

 remarkable peak, which he had first seen from a distance of about 

 '25 miles, the native name of which is Tangulda, and which is now 

 identified as Barber's Pinnacle, north of Wilberoi House (Plate 

 Ixvi.).* A list of the flora on this peak is given in this paper. 



After proceeding north-east by north from Barber's Lagoon, for 

 over 20 miles towards the Nandewars, Mitchell found the country 

 beyond Maule's Creek almost inaccessible for horses, and returned. 

 He then continued his journey down the Namoi, passing eastward 

 of Narrabri, and thence northerly, until reaching the Gwydir some 

 G-8 miles above Moree. 



On the 2nd January, li>32, somewhere to the eastward of Narra- 

 bri, Mitchell discovered the species which was afterwards named 

 Capparis MitchelU, and specially remarks that he only saw one 

 tree of it during the whole of the expedition. He next found 

 it on the Lower Bogan in 1835 (Vol. i., p. 284). The species is 

 nut uncommon in the Boggabri district. 



Tlie following plants were found chiefly between the head of 

 Maule's Creek and Boggabri, by far the greater number occurring 

 below an altitude of 1,200 feet:— 



RANUNCULACE.E : Clematis arislata R.Br., C microphylla DC, 

 Rammculus lap paceus {Buitercwp) . 



DiLLKNiACKiE : Ilibhertia linearis., var. ohtusifoiia. 



Papaverace^ : Argemone nifxicana L., (Mexican Poppy. 

 Naturalised), Papaver horridum DC. 



Crucifer.e : Capsellahursa-pastoris .\Icench(Shepherd"s Purse), 

 Lcpidium pseudo-ruderale Thell., Senebiera didyma Pcrs., (Pep-

Capparide^/e : Capparis MitchelU Lindl.,(Wild Orange), Apo- 

 phyllum anomalum F.v.M.,( Warrior or Currant-bush).
