one, a Typhonlum^ which forms a subgenus distinct from Sauratium; 

 several Eriocaulons, one Triglochin, Crinum angmtifoliuniy Pandanus 

 pedunculatus, and a species with free drupes, which, if distinct from the 

 Indian kinds, may be called P. aquaticus, as it indicates, and lives per- 

 manently in water, and has been introduced as " Water Pandanus " in 

 Dr. Leichhardt's work. Tacca pinnatifida is common ; Najas Indica^ 

 Potamogeton nutans^ a Ledehouria /, and a new Alisma {A. acantJiocar- 

 pum) remarkable for a limited number of thorny carpels, are our water 

 plants. Typha^ 1 species, Dioscorea bulbiferuy Angiiillaria hidica^ Car- 

 tonema spicatiim^ Aneilema anther icoideB^ Cganotis^ n. sp. {C. canalicii- 

 lata)y Commelgna undulata^ and a species not described by K, Br. Ma- 

 gellaria Indica^ and one Desvauxia^ comprise the rest of Monocotyle- 

 donecBy with exception of Cyperaidece and Grasses. Of the latter I 

 only say, that, to our horses' delight, they prove next Leguminosce to be 

 the largest Order in this part of Australia, and contain a good deal 

 that is new ; for instance, two undescribed A^itJdstirias^ two new spe- 

 cies of CenchruSy several, at least in Australia, unknown ; Andropogons, 

 Neurachne, Oryza^ Lappago^ and Glyceria seem formerly unnoticed within 

 the tropics of Australia. I have recognized Sporobolm Indicus, pul- 

 ckellus, a species of Perotisy several Aristidm^ Poa polymorpha^ P. 

 tenella, Triodia pungem^ Arundo Phragmitesy Eriachne sqitarrosa^ 

 glaucUy avenariay capiUaris, Pappophomm pallidum^ P. purpurascens ,

 semialatuniy P. decomposituniy P. l/Bvinode, P. papposum, P. jspinescens, 

 and several which I consider new. Xerochloa, sp. ; TAouarea, sp. ; Spi-

 is a Scirpus, new for the Australian flora, several Cyperi, Hypaliptum 

 microcephaluniy Fuirena glomeratay Tsolepis barbala^ Hekocharis compacta, 

 IL capUatUy about twenty Fimbrisiylis sp., which I have all ininutely
