of Three New Species ; on the Genus Colletia, discovered by Dr. 
Gillies ; a Notice of some Species of the Genus Verbena, disco- 
vered by the same gentleman in the extra tropical parts of South 
America ; of Macrwa, a new genus from Chile ; and Remarks on 
the Structure and Germination of the Lemna Gibba, by Wm. 
Wilson, Esq. of Warrington. ‘Two most important communica- 
tions complete the part ; the first, which we are sorry that we can- 
not lay at length before our readers, is the Sketch of a Journey to 
the Rocky Mountains, and to the Columbia River in North Ame- 
rica, by Thomas Drummond, full of interesting information ; and 
the second, Remarks on the Botany, &c. of the Banks of Swan 
River, Isle of Buache, Bay Geographe, and Cape Naturaliste, by 
Charles Fraser, colonial botanist. This is a garden from which we 
have also culled many pretty flowers for our account of the Swan 
River given in the present Number. 
_ We have now come to the third and concluding part of the first 
volume, and are glad to find an ever-increasing interest in its pages. 
The leading article is a Journal of 'wo Months Residence on the 
Banks of the Rivers Brisbane and Logan, on the east coast of New 
Holland, by Mr. Frazer. The country is new, and the information 
new ; but we can only refer our readers to the original. It really 
grieves us sorely to pass over the descriptions of so many new genera, 
and so many interesting species adapted toour gardens and hot-houses, 
and not be able to enter with scientific minuteness on their history ; 
but the remembrance that they are accessible to the public, and that 
we have called their attention to them, takes away from the bitter- 
ness of the consideration. There is a monegraph on a new genus 
of the natural order of Tiliacew, from the island of Madagascar, 
communicated by Professor Bojer of the Mauritius,—description 
of Malayan Plants, from Jack’s Malayan Miscellanies,—some Re- 
marks on the Species of the Genus Crtrus, which are cultivated in 
Jamaica, by Dr. James MacFadyen,—on the Plants of the natural 
order Umbellifere, detected by Dr. Gillies in the extra-tropical _ 
parts of South America, by the Editor,—on a New Genus of 
Plants of the natural order Cruciferw, from the Andes of Chili and 
Mendoza, &c. &c. 
There are further some interesting notices of the botany of the 
Philippine and Marian (Ladrone) islands ; also of the peninsula of 
Kamtschatka, and neighbouring archipelago, translated from Cap- 
tain Kotzebue’s voyage of discovery. ) 
The beautiful woods which clothe the mountains and vallies of the 
former district with luxuriant green, descending to the very brink of 
the sea in groves of mangle trees, (Rhizophora,) consist principally 
of fig-trees, and numerous genera of leguminous plants. Palms are 
more numerous than at St. Catherine’s: the slender prostrate Ro- 
tang is the most interesting. Amongst the Aroidez is the Pothos 
scaudens. ‘The graceful bamboo cane grows abundantly on the 
banks of brooks. The plains consist alternately of woods and sa- 
vannahs: the vegetables of the latter are chiefly two species of 
grass, which grow about eight feet high. |
