NEW AND RARE PLANTS, 
FIGURED IN THE LEADING BOTANICAL PERIODICALS FOR JULY. 
CLASS I. — PLANTS WITH TWO COTYLEDONS (DICOT YLEDONEiR). 
COMPOSITE. 
Centaurea depress a. Prostrate Centaury. A hardy species, with brilliant 
blue flowers, much resembling the common " corn blue-bottle" of this country, but 
far superior to it in the colour of its blossoms, and likewise less strong and vigorous 
in its habits. It is a native of dry, hilly places in Iberia, and seeds of it were 
communicated to the Glasgow Botanic Garden, by Dr. Fischer. It appears to 
thrive well in the open border, and blossoms in the month of August. Bot. 
Mag. 3662. 
THE BINDWEED TRIBE (Convolvulacea). 
Ipomcea bonariensis. Buenos Ayres Ipomcea. A beautiful new climbing 
species resembling /. HorsfallicR in habit, but having pale purple-coloured flowers, 
and the whole plant being clothed with a downy pubescence. Seeds of it were 
introduced to this country by Mr. Tweedie, from Buenos Ayres, where it is stated 
by him to be common on ditch banks, and to possess naturally a large tuberous 
root. It is a stove species, of easy culture, and flowers about the month of August 
in this country. Bot. Mag. 3665. 
THE FIG WORT TRIBE (Scrophulariacece). 
Nemesia floribunda. Many-flowered Nemesia. An interesting little annual, 
growing from nine inches to a foot high, and producing an abundance of its pretty 
blossoms in the open ground from June to August. It grows nearly erect, is dis- 
posed to branch, the leaves are opposite and much serrated, and the flowers are of 
a very pale, bluish-white colour, with a deep yellow spot at the mouth. Requires 
the same treatment as the common hardy species of Linaria, to which this genus is 
nearly allied. Bot. Reg. 39. 
THE MINT TRIBE (Labiata). 
Salvia canescens. Hoary Sage. Seeds of this pretty herbaceous plant were 
transmitted to the gardens of the Horticultural Society, by Dr. Lebedour, of 
Dorpat, where it has been raised, and proves to be a hardy perennial. Its leaves 
are clothed with a whitish woolly substance, and the flowers are of a showy purple 
colour. It is found on rocks, in that part of the Caucasian chain which runs into 
the west of the Caspian Sea ; hence it is a suitable plant for rock-work. Increases 
readily by seeds or cuttings, plants raised by the former method not flowering till 
the second season. The month of June is its usual time of flowering. Bot. Reg. 36,
