190 BOTANY OF THE INTERIOR OF NEW SOUTH WALES, 



points of geological interest. Plants are very plentiful, and many 

 are met with here which do not occur to the eastward, but extend 

 across into South Australia. The localit}- may be regarded as 

 being on the eastern boundary of the true interior flora. 



Various trees and shrubs noticed around Wyalong and tov. ards 

 Barmedman were : — Bertya Cunninghamii, Sterculia diversifoJia, 

 Myoporum deserti, Melaleuca parvijlora, J/, uncinata, Olearia 

 phneloides, A. Cunn., 0. lepidopht/lla, Benth., Eriostemon difformis, 

 Philotheca ciliata, Hook., Bursaria spinosa, Pittosporum phiHy- 

 rceoidesy Fxocarpus aphylla, Phehalium glandidosum, P. ohcorda- 

 tum, A. Cunn., Callit7'is robusta, C. calcarata, Halea leucopdera, 

 Cassia eremophila, Calythrix tetragona^ Casuarina Luehmaiini, 

 C. Cambagei, Cassytha sp., Dodonce.a sp., Heterodendron olecefolium, 

 Templetonia egena, Benth., Fusanus acuminatus, Thryptomene 

 Tninutiflora, F.v.M., Lissanthe strigosa, R.Br., Prostanthera 

 coccinea, F.v.^l., Solanuin simile, F.v.M., Helichrysum obcordatum, 

 F.v.M. , and Leptospermum myrsinoides, Schl. This last-named 

 species was also found north of the Lachlan, and was previously 

 mentioned as Tea-tree (Part iv., p. 325), but not then definitely 

 identified. 



The species of Cassytha growing at AVyalong is found as a 

 parasite clinging to and often almost smothering the top of the 

 Mallee or other bushes, the leafless vines being so numerous as in 

 many cases to form quite a canopy. They are often known as 

 Mallee-vines, and are useful as a fodder. The fruits are con- 

 sidered edible by children. 



Eriostemon difformis flowers profusely around Wyalong ■ in 

 September, and contributes much to the beauty of the flora. 



Pliebalhtm obcordatum was found at Wyalong only, and, 

 judging by its absence from herbaria, is evidently a plant not 

 often met with by the collector. It is somewhat difl'use in its 

 habit, and when covered w^ith yellow flowers is an ornamental 

 little shrub. Usually the colour of a flower is decided by the 

 colour of its petals, but in this species it is from the anthers that 

 the yellow appearance emanates, a feature, of course, not confined 

 to this genus. I have noticed these flowers apparentl}^ change
