324 NORTH AUSTUALIAN BOTANY. 



mistemma 1 ; of Hibbertia several ; of Thotiinia 1 ; of Pitfospo7*um 1 ; 

 oi EloBOcarpus 1. With CocJdospermum Jieteroneurum^ PacTiynema con- 

 planatumy Nymphtjea carulea^ Carapa Moluccensis, and 3 species of 

 Melia, I conclude the remarks on Thalamiflorce as far as they are 

 examined. 



Amongst CalyciJlor(s I noticed 2 sp. of TriantJi^ema^ 1 of Sesuvium, 5 

 of Portulaca^ including the cosmopolitan species, which proved exceed- 

 ingly beneficial to us, 2 sp. of Calandrinia, 2 of Mollugo, Glinm loto- 

 ides, and a new genus amongst Fortulacets. JSttphorbiacete are not so 

 numerous as might be expected, comprising several Phi/llanthiy 4 sp. 

 of Enphorhia, 1 of Rottlera, 1 of Leptoneura, and two new genera, be- 

 sides a few plants unexamined, and Adriana acenfolia. Of Myrtacem 

 I saw a new Lhotzkya {L. cuspidata), 3 sp, of Calycothnx, 1 sp. of 

 Vh'iieordia {V. scariosd), 1 of Bceckea, 1 diKunzea?^ about 12 Huca- 

 lyptiy including E. rostrata, 4 sp. of Melaleuca, 2 sp. of Tristania, 1 sp, 

 of Jamlosa, and a new genus {Xanthostemon), which requires yet to be 

 compared with your Backhousia, of which I have no diagnosis at hand. 

 Barringtonia shows here 2 splendid species, Melastoma 1, Osbeckia L 

 Haloragis 3, including S. glatica and H. aspera. JJmbelUJloriB are re- 

 duced to 3 species ; two of them form a most remarkable genus, He- 

 micarpus, having only 1 mericarp developed ; the third species is of 

 the appearance of a Sison, and bore, on the solitary place where it was 

 seen, neither flowers nor fruits. Lytliracem are more numerous in Aus- 

 tralia than was expected, comprehending 4 species either of Ammannia 

 or Rotala. 1 new genus {Calopeplis), allied to Lythrum and Peplis, Of 

 Cucurbitacea I found 1 Luffa, 1 beautiful Trichosanthes, 2 sp. of Cucur- 

 hita, of which one (C. jucunda) yields eatable fruit, and an unexamined 

 genus. Dr. Leichhardt speaks of several other Cucurbitacea, which 1 

 have evidently not yet seen. Of Stackhozisiece occurs but 1 sp. Legt^' 

 fmnos^e form the largest Order of all, with about a dozen Acacias^ in- 

 cluding A. dimidiata, dolibrata, lycopodifolia ; 8 Camas, all distinct 

 from those in the South, one having only 3 or 4 flowers (C oligandrd)\ 

 a second and very marked species of Petalogyne {Petalostylis, B. Br., 

 non Griesebach) which I named P. cassioides,^ Alms precatorius, Inga 

 moniliformis, Bauhinia Leichhardtii, Erythrina Fe^ertilio, E. hilohat
