triphylla. The flowers are small, in long spikes of a pale 

 lilac color; the celebrity of the plant is in the delightful 

 odor of its foliage, which is linear, lanceolate, and ternate. 

 It is of very easy culture, and has been known to survive 

 winter in the open air in Philadelphia. Where large plants 

 are desired, they should be planted in the ground during 

 summer, and lifted in November, and put in a dry cellar or 

 under the stage in the green-house. Before they begin to 

 grow in the spring, trim the plants into a neat shape.

Ahfroemerias, about sixteen species, all exceedingly de- 

 sirable, and many of them particularly beautiful ; such are 

 A. diirea, golden flowered ; A. hicolor, salmon and orange ; 

 A. carminafa, carmine-colored; A. Hookeriiy rose-colored; 

 A. pelpjjrina, elegantly spotted ; A. pulcMUa, red-flowered, 

 and will grow six feet high, having its shoots crowned with 

 a profusion of flowers ; A. ])sittacina, red, yellow and green ; 

 A. tricolor, black, white and yellow ; very beautiful. They 

 have, generally, tuberous roots, and should be potted into 

 fresh soil as soon as they show symptoms of growth, and 

 they will require repotting about every month previous to 

 flowering, taking care never to break the ball of earth while 

 they are in a growing state. (Soil No. 10.) 



Amari/Uis. This is a genus of splendid flowering bulbs, 

 containing about eighty species and one hundred and forty 

 varieties. They are natives of South America, but more 

 than one-half of them are hybrids grown from seed by cu-1- 

 tivators. They are generally kept in the hot-house, but in 

 our climate will do perfectly well in the green-house ; and 

 we have no doubt that in a few years many of them w^ill be 

 so acclimated as to keep as garden bulbs, planting about 

 the end of April, and lifting them in October. As the 

 beauty of these plants is in the flowers, it will be proper to 

 give a small description of a few of them. A. lella, pure 

 white striped with rose ; A. Bartonii, creamy white striped 

 with pink ; A. Buistii, large pure white, striped with cherry 

 color ; A. ignescens, bright red, with white at the base of 

 the petals. A. Johnsoni, the flowers are a deep scarlet, 

 with a white streak in the centre of each petal, four bloom 

 on a stem of about two feet, each flower about six inches in 

 diameter ; a bulb well established has two stems. A. reglna, 

 Mexican Lily, has large scarlet pendant flow^ers, tube of tJic
