inches high. Wherever a stove plant of any sort can be grown, 

 there should be found this splendid species. 



P. Benlhamiana is a fine free-growing species with purple flowers, 

 worth a place in a collection, but less desirable than others we 

 recommend. 



P. sarmentosa, the plant here figured, may be grown to perfection 

 in a warm greenhouse. It was discovered by Humboldt and 

 Bonpland in the cool valleys of Peru, near Cuenca, and has since 

 been found by Dr. Jameson on the same spot, at an altitude of 8000 

 feet, sufficient proof of its comparative hardiness. It is a rather 

 slender, half-climbing shrub, producing abundance of flowers, two to 

 two and a-half inches in diameter, the colour deep violet, shading 

 into deep blue, and varying slightly, perhaps, according to the degree 

 of light they are produced in, and the state of the plant as to health 

 and vigour. IS. H. 



ORNAMENTAL LEAVED PLANTS EOE THE 

 GREENHOUSE.

PLANTS with ornamental leafage that thrive well in a 

 greenhouse temperature are not so plentiful as those 

 which require the warmth of a stove. Nevertheless, they 

 exist in larger numbers than is commonly supposed to 

 be the case ; and for the help of those who have only a 

 greenhouse or conservatory, I intend pointing out a few that are well 

 suited for growing in these structures. Many of the subjects that I 

 shall enumerate grow with a greater vigour in the warmth of a 

 stove or vinery, particularly the palms ; therefore, when the latter 

 come to hand in a young state, or are raised from seed, it will be 

 well to give them a little warmth for a year or two to enable them 

 to develope the beauty of their leafage earlier than they do when 

 growu in the greenhouse from the first. If there is no heat to put 

 them in, never mind, as the growth will be equally good, though 

 comparatively slow. 



To avoid repetition, here I may be allowed to remark, that 

 nearly the whole of the subjects that I shall name will thrive well 

 in a mixture of sound turfy ioam.'fibry peat, and silver sand. When 

 preparing it for potting, break the loam and peat up rather roughly, 

 according to the size of the plants it is intended for. Mix in the 

 proportion of two parts loam to one of peat, and then add about a 

 sixth part of sharp silver sand. All will require potting moderately 

 firm, and the assistance of a thorough drainage. The foliage must 

 be kept clean either by sponging, or washing it with the syringe, 

 according to its nature. In the winter, where practicable, the 

 sponge should be used in preference to the syringe, as very few 

 plants, especially those with variegated foliage, will stand the pro-
