Calysterrja pubiscens. — This beautiful plant, which we 

 have already described, (p. 358,) and which has recently 

 flowered in our collection, will probably prove a most valu- 

 able summer flowering plant. M. Van Houtte states that 

 the mere figure of the plant does not give scarcely any idea of 

 the " floral luxury which is developed under good culture. 

 The little roots or rhizomes were left in ihe open ground, only 

 protected with a good covering of leaves, and this year they 

 flourished in a most remarkable manner. The branches were 

 more than six feet long, and much ramified, gracefully i win- 

 ing round the branches of trees which had bien placed in the 

 form of a hedge, and entirely covering them with their leave's. 

 They flowered splendidly all sunmier, and were, as late as 

 Sept. 1.5th, covered with a multitude of blossoms, nnich larger 

 in size, and more brilliant in coloring, than the English fig- 

 ure. The flowers are quite full and double, of a beautiful 

 rose, and, in their form, resemble large, irregular roses, which 

 have been fixed upon the stem of a Convolvulus. Experi- 

 ence proves that if will be a fine acquisition to summer flow- 

 ering plants in the open air." From the success which has 

 attended the culture of Ipomaeas in the open ground, we sus- 

 pected that the Calystegia would thrive well ; but it nas hith- 

 erto been rather too rare to spare the plants for this purpose. 

 Another year, we shall try M. Van Houttes plan. — Ed.

A very showy and beautiful shrub, attaining the height of 

 four or five feet, with branches clothed with immense clus- 

 ters of yel'ow and scarlet tubular flowers, somewhat resem- 

 bling the larger heaths. The flowers appear only on the two 

 year old wood, in pendent fascicles of from twelve to twenty 

 each, in all the stages of development, and, from their peci.liar 

 striated aspect, present a remarkably gay appearance. It 

 was found in the north of India, by Dr. V\ allicli, and it has 

 recently been introduced to Englan<i by Messrs. Lucombe,
