NEW AND RARE PLANTS, 
FIGURED IN THE LEADING BOTANICAL PERIODICALS FOR MARCH. 
CLASS I.— PLANTS WITH TWO COTYLEDONS (DICOTYLEDONEiE). 
THE HEATH TRIBE (Ericacea). 
Erica Florida ; var. campanulata. Drooping round-headed Heath. A 
very charming heath, raised from seeds of E. Jlorida, and communicated from the 
gardens of Bothwell Castle. The plant when figured was only two years old, and 
had attained the height of two and a half feet, producing its beautiful, delicate, 
rose-coloured terminal flowers, three or four together, forming small umbels 
at the extremity of the short lateral spreading branches. The plant flowered in 
May, 1837. Bot. Mag. 3639. 
Erica chloroma. Green-tipped Heath. This pretty heath was communi- 
cated by Mr. J. Young, Nurseryman, Taunton. It forms a handsome, erect, 
spreading bush, with reddish-brown downy branches ; the leaves are in fives, and 
the beautiful crimson and green flowers are produced in clusters at the ends of the 
young shoots, on little downy nodding pedicles. This species is very distinct from 
any found in books. Flowers in November. Bot. Reg. J 7- 
THE BIRTH WORT TRIBE (Aristolockiacece) . 
Aristolochia saccata. Pouch-flowered Birth wort. A singular plant, native 
of Silhet, and imported to the Botanic Garden, Edinburgh, from the Calcutta 
Garden, in 1829. It is a twining shrub, with very long slender stems, and 
scattered ovate-cordate leaves, from twelve to fifteen inches long and about four 
broad ; they are entire in the edges ; when young they are covered with brown 
hairs, when old they are less hairy. The racemes rise from the stem near its 
base ; the membranous pendulous flowers are covered with spreading hairs ; the 
tube is yellowish-white within and without; the circular throat is of a bright 
yellow colour ; the upper surface of the limb is dark purple, covered with warts 
of a similar colour. The plant produced a succession of flowers in September last, 
but Dr. Graham did not perceive that exceedingly offensive smell for which Dr. 
Wallich says its blossoms are remarkable. Bot. Mag. 3640. 
THE INDIAN FIG TRIBE (Cactacece). 
Mammillaria atrata. Dark-green Mammillaria. Another interesting 
species of Mammillaria communicated from the rich collection of the Messrs* 
Mackie, of Norwich ; with them the plant produces its pretty dark-green flowers 
in very high perfection. Sir W. J. Hooker says that Pfeiffer, in his useful 
■ u Enumeratio Cactearum," refers the M. atrata of our gardens to the M. rhodantha 
of Link and Otto, but from that species, says the above gentleman, our plant is 
wholly different, Bot. Mag. 3642.
