tions to perfection, but seeing all the species of a genus growing 

 together in the same garden, and studying them thex-e for several 

 years. Things, however, must go on as they are for a long 

 time; but, however impracticable the possibility of studying all 

 the species of a genus in die same garden may seem at present, 

 it is an object that, with the progress of civilisation and science, 

 will certainly be ultimately attained. When there shall be bo- 

 tanists and botanic gardens established in almost every country, 

 and a universal intercourse among botanists, it will then be a 

 comparatively easy matter to assign to each garden the genus or 

 genera which it ought more particularly to contain. 



To return to the figures in the Botanical Register : they are 

 most beautifully executed; and, being of the natural size, and 

 coloured, and of species more absolute and limited in their forms 

 than most others of the genus, they cannot fail to enable any one 

 instantly to recognise the species they represent.

 *lepida Lindl. pretty O pr 1| au.s Pis California 1835 S lt.l Bot. reg. 1849 



" A pretty new annual, found in California by Mr. Douglas, 

 and raised in the garden of the Horticultural Society, in July, 

 1835. In some respects, especially in the spots on its petals, 

 it resembles Godet/« (ffinothera) quadrivulnera, but is more 

 handsome than that species : in reality, it is more nearly allied 

 to Godet/a (6Enothera) decumbens ; but that species, independ- 

 ently of its glaucous leaves, decumbent habit, and whole- 

 coloured flowers, has less shaggy and more linear fruit." {Bot. 

 Reg., April.) 



The genus Godet/a has been formed from certain species of 

 6Enothera, by M. Spach, a German botanist resident in Paris, 

 who has published several monographs of both herbaceous and 

 ligneous genera, in the Annates des Sciences Natiirelles. Copies 

 of several of the latter M. Spach has been kind enough to send 

 us, together with dried specimens illustrative of his names, and 

 for which mark of attention and kindness we take this oppor- 

 tunity of returning M. Spach our best thanks. We shall notice 

 M. Spach's arrangement of the hardy ligneous genera, to which 

 he has directed our attention, in the Arboretum Britamiicum.

An extremely beautiful melastomaceous plant, raised in the 

 Glasgow Botanic Garden, from seeds received from the col- 

 lector, Mr. Tweedie, who sent them from South Brazil. It 

 requires the heat of a stove, and blossoms in June. [Bot. Mag.f
