164 HOT-HOUSE — OF REPOTTING, ETC. [May. 
pandursefblia have the handsomest foliage, and both have 
scarlet flowers : the appearance of the foliage of this genus 
is the only object; the flowers are small, in coarse disfigured 
panicles, and several of the species have not been known to 
flower in artificial cultivation. The seeds of J. ciircas are 
often received from the West Indies ; the leaves are cordate, 
angular and smooth. J. mant'hot, now Manihot cannab\na, 
is the Cassada root, the juice of which, when expressed, is 
a strong poison. Tbey 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. 17.) 
Justicia. A few species of this genus are fine showy hot- 
house plants. J. eamea, flesh-colour flowers in large spikes, 
very fine, blooming nearly the whole season. 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 spindly, if not kept near the glass. /. picta, with its 
varieties, I. lucida, and /. calyctricha , are fine shrubby spe- 
cies. I. specibsa is a beautiful profuse, purple flowering 
plant. (Soil No. 11.) 
La ii tan a, 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 changeable colours; 
principally of a rough, straggling growth, and are not es- 
teemed. However, L. scl/bi, light purple ; L. mutdbilis, 
yellow, orange, and pink; L. bicolor, wbitc and pink, and L. 
fardta (or Donylasii of some), lilac and white; L. rosea, 
white, changing to rose; L. Mexicana, very rich orange, one 
of the finest. 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 ope- 
ration, they must be set down in the pathway, or other low 
part in the house. (Soil No. 9.) 
Lasiandra, a genus related to melastoma, of which there 
are several very handsome species. L. splendem with 
hirsute rich crimson foliage and brilliant purple flowers, 
blooming from January to May. L. Bentliamiana with very 
elegant foliage and rich bluish purple flowers, grows freely 
in Soil No. 1. 
Latdnias. This genus contains three species of handsome
