Cassia Cookii, sp. nov. 
Plate YI, Fig. 19. 
Sp. Char. — C. foliolis coriaceis sessilibus (?), oblongo-ellipticis, basi 
rotundatis, insequilateris, apice acuminatis, margine integerrimis ; ncrvationo 
camptodroma ; nervo primario valido, prominente, recto apicem versus 
angustato; nervis secundariis tenuissimis, sub augulis G5-75° orientibus; 
nervis tertiariis obsolctis. 
Ohs. — A leaflet which in its peculiarities resembles most nearly those 
of Cassia naseolites, Ung., but appears to have weaker secondary veins than 
the fossil plant named, so widely distributed in the Tertiary Flora of Europe. 
At the present time there are twenty-one species of Cassia endemic in 
Australia ; it may therefore be assumed that Cassia existed there even during 
the Tertiary Epoch, and for these reasons the described leaflet may with so 
much the more probability be referred to that genus. So far, only one specie, 
of Cassia* is known from the Tertiary Flora of North America. 
I name this species, which appears to be distinct from Cassia phascolilcs , 
after the British Navigator, Captain Cook, who on behalf of the lloyal Society 
of London, it is well known, made most inqiortant discoveries in Australia, 
Localihj and Horizon. — With the preceding species. 
Cassia Flixdeesi, sp. nov. 
Plate VI, Fig. 18. 
Johnston, Notes, etc., Papers and Proc. R. Soc. Tasmania, for 1881 [7th Plate], fig. 13. 
Sp. Char. — C. foliolis subcoriaceis petiolatis ovato-ellipticis, basi 
imequalibus, apice obtusis, margine integerrimis ; nervationc camptodroma ; 
nervo primario distincto recto excurrente ; nervis secnndariis tenuissimis ; 
tertiariis inconspicuis. 
Ohs . — The occurrence of the genus Cassia in the Tertiary Flora of 
Australia is again made evident from this leaflet, which is similar to those of 
* Cassia podogoniuides, sp. nov. ( Potlononium amtricanum, Lesquereux, loc. cit., p. 280, PI. LIX, tier. 5 ; 
PI. LXIII, fig. 2 ; and pi. LXV, fig. G). 
Obs . — The leaflets of Lei/uminosce figured by Lesquereux in the work quoted, have not the venation of 
Podogoninm, but of Cassia. They want the acrodromic secondary veins at the base of the leaflets, which are 
characteristic of Podogonium. On the other hand, the venation of the leaflets shows more correspondence with 
those of Cassia Zephyri, Ett. , and C. Fischeri, Heer, which also have a somewhat narrowed base. In form, and 
as regards the approximate secondary veins, the leaflets are certainly somewhat similar to those of Podogonium.
