A List of Plants Collected by the Calvert 

 Expedition. 



By Professor Ralph Tate. 

 [Read July 6, 1897.] 



The collection of plants under review is supplemental to the 

 main gathering made by the naturalist to the Expedition (Mr. 

 Keartland) which was abandoned at Joanna Springs. It was 

 made between December 22, 1896, and March 17, 1897; firstly 

 whilst stationed at the junction of the Fitzroy River and 

 Margaret Creek, about 150 miles from Derby ; and secondly, 

 whilst on the search for his missing colleagues, embracing 100 

 miles down the Fitzroy, thence south to near Joanna Springs, 

 and thence to Derby. 



The collection comprises about 100 species, but about a moiety 

 of them is represented by foliage, though of the latter a few admit 

 of assignment to specific denomination. 



The facies is that of the Eremian botanical province, largely 

 comprised of Indo- Australian species, such as prevails over the 

 table-land skirting the littoral tracts of North- Western Aus- 

 tralia. 



The region botanically explored by Mr. Keartland has been 

 somewhat extensively reported upon by the late Baron Mueller 

 through the collections made by himself, Mr. F. Gregory, Sir 

 John Forrest, and lately by Mr. Tepper (" Plants of Roebuck 

 Bay") in Trans. Roy. Soc, S. Aust., 1892. 



Rare or previously unrecorded species are the following: — 

 Capparis umbonata, Hibiscus panduriformis, Polycarpcea 

 violacea, Trichinium arthrolasium, Gomphrena affinis, G. 

 Brownii, Cassia concinna, Indigo/era viscosa, Neptunia gracilis, 

 Acacia suberosa, A. dineura, Melaleuca lasiandra, Gardenia 

 Keartlandi, n.sp., Tragus racemosus, Perotisrara, and Andropogon 

 gryllus. 



Of the various collections made from this region it is note- 

 worthy how few are the species in common, and though the 

 greatest number enumerated in any one collection does not 

 exceed 250, yet in the aggregate the flora numbers over 600.
