240 HOT-HOUSE OF REPOTTING, &c. [MAY. 



. Ipomceas, a genus of tropical climbing plants, nearly 

 allied to Convolvulus, but of greater beauty. /. panicu- 

 Idta has large purple flowers in panicles, with large 

 palmated smooth leaves. /. Jdlapa is the true jalap of 

 the druggists, but not worthy of any other remark. /. 

 grandiflora, large white flowers, with acute petals; leaves 

 large, cordate, ovate. /. pukhella has flowers of a hand- 

 some violet colour. They are all easily cultivated. It 

 is said that /. tuberbsa is much used in the West Indies 

 to cover arbours, and will grow three hundred feet in 

 one season ; the flowers are purple striped with yellow, 

 leaves palmated. We are not certain but the roots of 

 this kind may be kept like the sweet potato, and be- 

 come a useful ornament to our gardens. 



Ixoras, a genus of fine flowering plants, and does ex- 

 tremely well in our collections in comparison to the 

 state they are grown in England. The genus specifi- 

 cally is much confused amongst us, either from error 

 originating with those who packed them for this coun- 

 try, or after they have arrived. /. purpiirea, leaves ob- 

 long, ovate, blunt ; flowers crimson ; it is now called 

 /. obovata. /. crocdta, leaves oval, lanceolate, narrowing 

 towards the stem, smooth, underside of the leaf the 

 nerves are very perceptible ; flowers saffron coloured. 

 /. rbsea, leaves large, regular, oblong, a little acute, 

 very distant on the wood, centre nerve strong ; flowers 

 rose coloured in large corymbs, branching : /. Band- 

 huca, leaves very close to the stem, ovate, accumulate; 

 nerves straight, middle nerve stronger than any other of 

 the genus ; flowers scarlet, corymbs crowded. /. Bldn- 

 da, leaves small, lanceolate, ovate ; flowers blush, cymes
