We have seldom had the satisfaction of publishing a more charming greenhouse 
>lant ; the prevailing colour of its flowers is of so delightful a description, and they 
re so freely produced in spring and early summer, its branches slender, and the 
labit of the plant elegant and quite in accordance, renders it particularly desiiable. 
for our figure we are under obligation to the kindness of Mr. Low, of Upper Clapton , 
t represents the plant rather more attenuate in growth than it naturally is, scaicely 
a full conveys an idea of how abundantly it blossoms, and does not exactly show the 
•eal colour of the flowers ; all in consequence of the plant from which it was taken 
laving been accidentally grown and flowered in too warm a temperature. 
Of the history of the species we have not much intelligence ; it is new, in a flow- 
ing state, at least, to our collections this season. The plant previously spoken of 
vas raised from seeds collected at the Swan Liver by Drummond, in Mr. Lows 
rnrsery, and flowered there in February, bearing the name of Tetratheca speciosa. 
)ther establishments have bloomed the plant under the name of Tremandra 
wrticillata, a title that has, we imagine, come with it from the collection of Laron 
Efugel, of Vienna. That it is a Tetratheca there can be no question, but as far as 
ve are able to learn, it is an unfigured and an undescribed one. Of the origin of 
he specific appellation we are also ignorant, but nevertheless give the name it now 
miversally and appropriately bears. A pleasing property distinguishing it fiom T. 
lirsuta, is, that its flowers remain expanded after once opening, and not like those 
>f that species, close in the absence of sunshine. 
The stream of floral attention, so to speak, has of late years, and is strongly at 
>resent diverted from the class of plants of which this is an individual, by the splcn- 
lour of the Orchid family, and the more gorgeous, more easily managed inmates of
