NEW AND RARE PLANTS, 
FIGURED IN THE LEADING BOTANICAL PERIODICALS FOR AUGUST. 
CLASS I. — PLANTS WITH TWO COTYLEDONS (DICOTYLEDONEJE). 
THE EUPHORBIUM TRIBE (EuphorMacece). 
Euphorbia rigida. Double-glanded Euphorbia. A hardy perennial species, 
of prostrate habits, and interesting chiefly on account of its thickly-set, rigid, 
glaucous foliage, and the contrast between the bright crimson and yellow colour of 
its floral envelopes, the latter being the internal, and the former the external colour. 
The Hon. F. Strangways brought this species from Italy, and it has endured the 
late severe winter in the garden at Abbotsbury, producing its flowers in March of 
the present year. It thrives well on rockwork if protected from wet, and partially 
sheltered from cold in the winter, and may be propagated by separating the under- 
ground shoots, or planting pieces of the roots with the thickest extremity slightly 
above the surface of the soil. Bot. Reg. 43. 
Euphorbia jacquiniflora. Jacquinia-flowered Euphorbia. It is curious to 
observe the striking difference in the appearance and habits of this species to that 
above noticed. This is a most beautiful stove species with brilliant scarlet flowers, 
greatly resembling the E.fulgens, figured vol. iv, p. 31 of this Magazine, and only 
distinguishable from it (as far as we can discern) by the less brilliant colour of its 
flowers, its leaves being of a lighter green, and particularly by the latter being 
destitute of the fine purple colour on the under surface which is so conspicuous in 
E. fulgens. Nothing is known with respect to its native country, it having been 
received at Glasgow from the Berlin Botanic Garden, where it flowered during the 
winter months. Bot. Mag. 3673. 
THE HEATH TRIBE {Ericacece). 
Rhododendron albiflorum. White-flowered Rhododendron. A remarkably 
distinct and well-characterised species, growing from two to three feet high, 
producing leaves only at the extremities of the branches, and these being deciduons. 
The flowers are smaller than those of most other species, cream-coloured, and 
pendent. It was found by Mr. Drummond in the woody districts of the Rocky 
Mountains, and seeds were communicated to Dr. Graham of Edinburgh, plants 
from which flowered in July 1837- Bot. Mag. 3670. 
THE LOBELIA TRIBE (Lobeliacece). 
Lobelia Bridgesii. Mr. Bridges' Lobelia. This is a very elegant and highly 
ornamental plant, first discovered by Mr. Bridges near El Castello de Amorgos, 
Valdivia, in the south of Chili. It grows to the height of three or four feet, with 
leaves occasionally more than six inches long, and the large blossoms are of a
