NORTH AUSTRALIAN BOTANY. 323 



which and Moreton Bay in all likelihood the principal harvest of plants 

 will be reaped. 



Impossible as it is to send at present extensive copies of my writings 

 home, I will endeavour to furnish you with a hasty review of my notes. 

 Amongst Thalamijlorce occur 2 species of lonidiiim new to Australia 

 (/. purpureum and aurantiacuni) ; of Gi&siis also 2 species, as I have 

 been obliged to refer the Vitis mentioned by Captain Stokes (C. acidd) 

 also to this genus. Of Cappans I have 3 species, of Cleome also 3, 

 one having pink flowers and the habit of an Oxalis {C.jlava^ C. tetrandra^ 

 C, oxalided), Sapindacece comprise Cardiospermum^ several fine new 

 Dodonceas^ and a new genus, DistichostemoUy allied to DodoncBa, Zy~ 

 gophyllecB are, even in the interior, destitute of the genus which forms 

 the type of the Order ] but I discovered a new Tribulus (T. rammculi- 

 Jloriis) remarkable for having 1-2-seeded carpels, so that, with its 

 upper leaves alternate, it comes into close contact with Tribulopsis^ 

 which furnished a beautiful new species, Tribulopsis lieter anther a ^ ad- 

 vancing the genus again to 3 species, since T, angtistifoUa has been 

 reduced to T, Solandri^ which, with T. pentayidra, is very common 

 even in the interior. Tribulus acaiitJiococcits has been also seen, like 

 Brosera angustifolia^ from the Murray. B. petlola7ns is common, and 

 occasionally accompanied by other species, of which one produces beau- 

 tifully blue petals. Pohjgala, mentioned by E. Brown as existing in 

 the tropics of Australia, is represented by 3 or 4 species distinct from 

 the southern one, but Comesperma is wanting, or at least not found. 

 Corchorus and Triumfetta, both with 4 species, augment their small 

 Order considerably in Australian botany* One species of Trinwfetta 

 {T, phmigera) is remarkable for a capsule which is not woody, and long 

 plumose setse of the fruit, characters that may entitle it to generic dis- 

 tinction. Dr. Steetz's excellent paper on Australian Buettneriace<B will 

 receive a supplement in 1 sp. of Seringia, 1 sp. oi Melochia, 1 sp. of 

 Melhania, 1 sp. of Rulingia, 1 sp. of Waltheria, mentioned by All. 

 Cunningham, and 1 of RidUya. Maltacem form a predominant family 

 with many species of Sida and Hihhcm; one species of the former 

 genus, Sida {Abulilon) leucopetala, having fine white flowers. Gossy- 

 pium AuMraU is common as far as we went, and an Abeltmschun {A. 

 atbo-ruher) diflFers from Ab. aplendens. A new Soulhwellia has quadrifid 

 flowers, and also 2 sp. of Brachychiton have been seen. Of MMormm 

 I met 1 sp. ; of Frankenia 1 ; of Boronk 3 ; of Volycarprm 4 ; of /A-
