162 HOT-HOUSE — OF REPOTTING, ETC. [May. 
the flowers are mellifluous, five-parted, and in pendulous 
bunches, slightly bearded, and have every appeartmce of a 
composition of the finest wax ; of a blush colour. H. cras- 
sifblia, H. grandiflora, brown flowered, H. bella, variegated, 
H. Cunningham ii and IT. imperialis are all well worthy of 
cultivation. (Soil No. 2.) 
Ipomseas, a genus of tropical climbing plants, nearly allied 
to Convolvulus, but of greater beauty. I. Jdlcepa is the 
true jalap of the druggists, but not worthy of any other re- 
mark. I. Horsfdllia has brilliant rosy crimson flowers, 
which it is almost entirely covered with from December to 
May. I. rugosa has a profusion of large rosy lilac flowers. 
I. multiflbra, blush and lilac. I. Learii produces a profu- 
sion of large blue flowers; they are all very showy and 
beautiful ornaments for either the hot-house or the flower- 
garden. (Soil No. 13.) 
Ismene amdncaes, or Panaritium amdncaes. This pro- 
fuse yellow-flowering bulb is richly deserving of cultivation, 
and should be kept in the house all summer, repotting it as 
often as the roots touch the interior side of the pot, giving it 
plenty of water when in a growing state ; but when dormant, 
it must be kept dry till it offers to grow : when well treated, 
it will bloom repeatedly during summer. (Soil No. 12.) 
Ixbras, a genus of fine flowering plants, and does extremely 
well in our collections in comparison to the state they are 
grown in England. The genus specifically is much confused 
among us, either from error originating with those who 
packed them for this country, or after they have arrived. I. 
purpurea, leaves oblong, ovate, blunt; flowers crimson: I. 
crocdta, leaves oval, lanceolate, narrowing toward the stem, 
smooth underside of the leaf; the nerves are very percep- 
tible ; flowers saffron-coloured, and very profuse. I. rosea, 
leaves large, regular oblong, a little acute, very distant on 
the wood, central nerve strong; flowers rose-coloured in large 
corymbs, branching finely; 1. bandhiica, leaves very close to 
the stem, ovate, acuminate ; nerves straight, middle nerve 
stronger than any other of the genus; flowers scarlet. I. 
bldnda, leaves small, lanceolate, ovate ; flowers red, cymes 
branching in three. I. dichotbna, leaves largest of the genus, 
ovate, acuminate, undulate footstalk three-eighths of an 
inch long ; whereas, none of the leaves of the other species 
have footstalks of any length; it is now called /. unduldta;
