258 GREEN-HOUSE REPOTTING. [March. 



they are not neglected in water, for if they are suffered to 

 droop, they seldom recover. For this reason the pots ought 

 not to stand in the strong sun ; the plants can bear it, but 

 to the roots it is injurious. (Soil No. 9.-) 



Pultenssas, about forty species, pretty little dwarf grow- 

 ing shrubs of New South Wales ; flowers small, legumi- 

 nose, all yellow, with a little red outside of the petals. P. 

 subumbetlcita, P. villosa, P. obcorddta, P. argentea, P. 

 plumosa, P.Jlexilis, shining leaved, fragrant ; P. Candida, 

 and P. stricta, are all fine species, and esteemed in collec- 

 tions. The leaves are all small; they require an airy ex- 

 posure, and the pots drained. (Soil No. 6.) 



Rhodochiton voliibile, or Lophospermum rhodochlton : 

 this is a very fine climbing plant, with large tubular dark 

 brown flowers, blooming from July to October ; it is of 

 rapid growth, and is an excellent plant for the flower-gar- 

 den. The plant must have frequet repottings to make it 

 grow rapidly, for the finer it grows the more profuse will it 

 flower. (Soil No. 12.) 



Rhododendrons, (Rose tree,) a magnificent genus, and 

 contains some of the most superb and gigantic plants that 

 adorn the green-house. At present the most admired is 

 R. arboreum with its varieties. It has deep crimson flow- 

 ers, with dark spots and flakes campanulated, and in large 

 clusters ; leaves lanceolate, acute, rough and silvery be- 

 neath, ft. arboreum album is very rare. R. arboreum 

 superbum, flowers same shape as arboreum, colour bright 

 rosy scarlet; foliage one-third larger, but not silvery be- 

 neath; grows freely, and generally thought the finest 

 variety. R. arborea dlta-Clarence is also very. superb. 

 R. arborea Russelidnum, pictum, venustum, guttdtum, 

 tigrinum, noblednum, grandi/lorum, spcctdbile, are all 

 very distinct; but there are so many other varieties from 

 seed that they Avill soon be so much amalgamated, that the 

 named sorts will not be distinguished. A green-house 

 without some of the choice varieties of this plant, is defi- 

 cient of a flower whose beauty and grandeur are beyond the 

 highest imagination. It is a native of Nepaul, in India, 

 and, when found by Dr. Wallach, awakened the ambition 

 of every cultivator and connoisseur in Europe.* There 



* Mr. Hogg, the eminent horticulturist of New York, raised the 

 first plant of arboreum from seed in England.
