DESCRIPTIVE LIST OP NEW PLANTS. 
delphicum , from which it is clearly distinguished by its upper 
leaves not being distinctly verticillate, and by its great woolly 
honey-furrow. It is a half-hardy bulb, growing freely in a light 
loamy or peaty soil.— Bot. Reg. 50-46. 
Brassicaceje. —Tetradynamia Siliculosa. 
Tonopsidium acaule. This is a charming, little, hardy annual, 
growing in any rich garden soil, and blooming from April to 
October. It attains a stature of only a few inches, but pro¬ 
duces a profusion of clear lilac flowers during the whole of the 
summer; it requires rather a moist situation, makes a neat 
edging to borders in shaded places, and is a capital rockwork 
plant. It is found wild near Lisbon, in Barbary, and occasion¬ 
ally on the limestone formation of Estramadura. De Candolle 
considered it a kind of scurvy grass, aud referred it to the 
genus CocMearia , but Reichenbach, perceiving that its radical 
lies against the back of the cotyledons, and not the edge, con¬ 
verted De Candolle’s sectional name of Tonopsis into that of 
Tonopsidium. — Bot. Reg. 51-46. 
Magnoliaceje. —Polyandria Polygynia. 
Talauma Candollii. A very charming shrub, whether its 
foliage, or its flowers, or the fragrance of the blossoms be con¬ 
sidered. It is a native of Java, and, therefore, requires the heat 
of a stove, when it flowers annually about the month of June. 
When in perfection the flowers are a cream colour, and more or 
less connivent, but they soon become tawny and more expanded. 
The plant attains, with us, a height of about four feet, the leaves 
are from seven inches to a foot long, and the flowers are large, 
drooping, handsome, and fragrant.— Bot. Mag. 4251. 
S OLANER3. —Pen tandria Monogynia. 
Datura cornigera. This plant is well known as Brugmansia 
Knightii. Dr. Hooker, however, appears to object to the genus 
Brugmansia altogether, and has adopted the above name in the 
Bot. Mag. 4252. 
GesxeriacE-E.-— Didynamia Angiospevmia. 
Diastema ochroleuca. A very pretty and ready-flowering
