572 Floristik und Systematik der Phanerogamen. 



Part I.: The districts concerned include low-lying warm and 

 upland (3300 feet) colder country, Eucalyptus hemiphlola var. albens 

 Miq. definitely marking the dividing line between the two and being 

 an undoLibted sign of warmer temperature. Starting from Wagga 

 Wagga (600 ft.) and travelling to Tumbarumba via Kyamba 

 the trees at first belong to forms usually found in the low country, 

 but gradually give way to those, occupying the areas on the western 

 slopes. After leaving Kyamba the Vegetation immediately changes 

 with the considerable ascent; the species of Eucalyptus above men- 

 tioned soon disappears, whilst E. tecticornis (var. clealbataf) is 

 found on the granite hüls; other common forms are E. macror- 

 rliyncha, E. polyanthemos, Sterculia diversifolia G. Don., Lepto- 

 spermum scoparium Forst., etc. From Tumbarumba onwards to 

 Laurel Hill (3300 feet) the common Eucalypts are: E. dives, E. 

 campliora, E. Bridgesiana, E. amygclalina, etc. The Vegetation of 

 Laurel Hill itseif bears a resemblance to that of parts of Tas- 

 mania, which is due to similarity of climate (common plants are: 

 Cleniaiis aristata R. Br., Drimys aromatlca F. v. M., Acacia slculi- 

 fonnis, etc.). No. species of Grevillea was noticed throughout the 

 Tumbarumba district. Some way beyond Laurel Hill the 

 country again falls considerably and the same zone of trees is 

 passed through, as was found when ascending from Kyamba 

 Tumbarumba. 



Part 11 deals with the country from Boggabrito Narrabri 

 and Morce to Inverell and Tingha. From Boggab ri to 

 Narrabri forms such as Eucalyptus populifolia Hook., E. melano- 

 pkloia F. V. M., Callitris robusta R. Br., Eremophila Mitclielli Benth. 

 etc. were noticed, whilst an area of sandstone bore E. trachypliloia 

 and Angophora lanceolata Cav. Between Narrabri and Morce 

 the country is one vast (black soll) piain, long Stretches being 

 without trees; the Eucalypts are few in number of species. Tra- 

 velling from Morce to Warialda the country rises to an ele- 

 vation of 1230 feet at the latter place, which has a distinct flora 

 (e. g. Eucalyptus melliodora, Angopliora intermedia, Capparis Mit- 

 clielli, etc.), though many western plants are found. Other charac- 

 teristic features of the country between Boggab ri and Warialda 

 are the absence of Acacia homalophylla, A. Cambagei R. J. Baker, 

 Flindersia maculosa F. v. M., Hakea leucoptera R. Br. and of every 

 species of Malle e. East of Warialda the country rises fast and 

 Tingha is about 2600 ft. above the sea; the flora is composed of 

 plants such as (Eucalyptus sideroxylon, E. Andrewsii, Acacia undu- 

 lifolia Fräser, A. venulosa Benth., Discaria australis Hk., Hibbertia 

 stricta R. Br., Olearia ramulosa Labill. etc. Beyond Tingha the 

 country rises to 4300 ft. at Guyra and a successive of Eucalypts 

 is noticed during the gradual ascent; the formation round Guyra 

 is chiefly basaltic with forms, such as Eucalyptus viminalis, E. ru- 

 bida, Clematis glycinoides, Discaria australis, Acacia melanoxylon, 

 Leucopogon lanceolatus, etc. F. E. Fritsch.
