with the same materials, and as roots were made they were 

 covered with more moss ; it was then suspended over tlie flue 

 where the fire comes into the house, and a large water-pot, 

 with a syringe, was always ready to give the plant a plentifi.d 

 supply of water at every opportunity, by which means that 

 part of the house was kept moist. I should add, that the 

 young roots in winter time ought to be well covered from a 

 strong fire-heat, as they may dry up too quickly. The east 

 end of the house is to be preferred for suspending the baskets, 

 boxes, or pots, in which the plants are grown : the water can 

 be applied to them there both in the morning and in the 

 afternoon ; and they can be kept more moist there than if 

 they were on the west side. The plants may be also placed 

 on the flues, but in all cases it is necessary to keep them 

 damp ; and care must be taken to surround them with suffi- 

 cient moss to retain the moisture." 



52. Upon the Cultivation of the Souvdrdia triph^lla. By Mr. John 

 Mearns, F.H.S. Read April 21. 1829. 



" About the middle of April I collect all my bouvardias 

 together, from the places where they have been kept through 

 the dormant season ; some among my orange tubs, others in 

 cold frames, and others under the stage of the green-house. 

 I turn them all out of their pots, shaking the soil completely 

 from their roots ; 1 thin off" most of the large roots, yet retain 

 as many of the fine fibrous ones as possible. I likewise, at 

 the same time, cut down all the former year's shoots, retain- 

 ing only two, three, or four eyes on each, according to the 

 strength and age of the plants. I then plant them in pots 

 suitable to the size of the plants, taking care neither to over- 

 pot them, nor to cramp the roots by confinement. When I 

 have got all potted, and watered to settle the earth about 

 their roots, I place them in a cold frame, which I cover with 

 hay and mats at night; I keep the lights close during the 

 night, and even in the day, unless the sun is very strong upon 

 them, till they begin to grow, when I give them portions of 

 air, according to the day, and their advance in growth. Sub- 

 sequently I leave the lights off" during the day ; and, lastly, 

 put them on at night. In about a week after they have been 

 exposed I plant them finally out for the season, either in 

 clumps by themselves, or distributed among other plants, 

 when they are soon in fine bloom, and continue to flower till 

 Christmas. By the autumn, some of the year's shoots will 

 have attained nearly a yard in length, and will be crowned 

 with fine luxuriant clusters of their splendid trumpet-like 

 flowers.
