168 HOT-HOUSE OF REPOTTING, &C. \_May. 



nihot cannablna, is the Cassada root, the juice of which, 

 when expressed, is a strong poison. They are all easy of 

 culture: want of strong heat in winter will make them 

 cast their leaves, but does them no other injury. (Soil No. 



Justida. A few species of this genus are fine showy 

 hot-house plants. J. coccinea has large terminal spikes of 

 scarlet flowers, blooming from December to March, and is 

 a very desirable plant, of easy culture, and should be in 

 every collection; it is apt to grow spindley, if not kept 

 near the glass. L picta, with its varieties, /. ludda and 

 /. calyctricha, are fine shrubby species. /. speciosa is 

 a beautiful profuse purple flowering plant. (Soil No. 11.) 



Ksempferia, an Asiatic genus of tuberose rooted plants ; 

 none of them in our collections, except K. rotunda; the 

 flowers come up a few inches above the pot, without the 

 leaves, in April and May, and frequently sooner; they are 

 purple and light blue, partially streaked and spotted ; leaves 

 large, oblong, purplish-coloured beneath. The roots, when 

 dormant, ought to be kept in the pot without watering, 

 otherwise they will not flower freely. No bulbs nor strong 

 tuberose rooted plants will flower in perfection if kept moist 

 when they are not growing. (Soil No. 17.) 



Lantana, a genus of twenty species, all free-flowering 

 shrubs; the flowers are small, in round heads blooming 

 from the axils, in yellow, orange, pink, white and changea- 

 ble colours; principally of a rough straggling growth, and 

 are not esteemed. However, L. selldi, light purple; L. 

 mutabilis, yellow, orange and pink ; L. bicolor, white and 

 pink, and L. fucdta (or Dougldsii of some), lilac and 

 white. These are very handsome growing plants, and 

 will even keep in a good green-house ; but in such case 

 will only bloom in summer. They will not bear a strong 

 fumigation; therefore, when the hot-house is under that 

 operation, they must be set down in the pathway, or other 

 low part in the house. (Soil No. 9.) 



Latanias. This genus contains three species of hand- 

 some palms. L. barbonica is one of the finest of the 

 Palmse, not growing to great magnitude ; the leaves or 

 fronds are plaited flabelliform, leaflets smooth at the edge, 

 footstalk spiny, and the plant spreading. L. r libra, fronds 

 same as the former, but leaflets more divided and serru- 

 late ; footstalk unarmed : foliage reddish. L. glattcophylfa,
