164 HOT-HOUSE OF REPOTTING, &C. [May. 



and deserving attention, are G. campanulata, of a soft 

 woody nature, with ovate, acuminate leaves ; flowers of a 

 straw colour, and solitary ; G. amaena, the flowers are white, 

 tinged with crimson, terminal and solitary, but seldom 

 bloom ; G. costata, admired for its beautiful ribbed foli- 

 age; G. lucida has a handsome, ovate, acuminate, shining 

 foliage, flowers white and solitary ; they require to have 

 the pots well drained. (Soil No. 13.) 



Geissomeria longiflbra. This is a new genus, and 

 closely allied to Ruellia. The species alluded to, is a free 

 flowerer, blooming from January to May, in close spikes of 

 a scarlet colour; leaves opposite, ovate, elongate, and shin- 

 ing ; the plants must be well drained, and in summer kept 

 from the direct influence of the sun. (Soil No. 2.) 



Heliconia braziliensis. This very splendid plant is 

 nearly related to Strelilzia, and in splendour surpasses it. 

 The brilliant scarlet sheath that envelops the flowers, con- 

 trasts most admirably with its rich green leaves. Give 

 plenty of drainage to the pots, and, when the plants are 

 growing, give a liberal supply of water. (Soil No. 17.) 



Helitropiums, about twelve species, of little merit, except 

 H. peruvianum, H. corymbosum, and H. grandiflorum ; 

 these are all very agreeably scented, especially the former, 

 which is a universal favourite. (Soil No. 3.) 



Heritiera littoralis, looking-glass plant. This plant is 

 unisexual, has beautiful large, ovate, veiny leaves ; the 

 flowers are small, red, with male and female on the same 

 plant, but different flowers. It requires a strong heat and 

 plenty of pot-room. How the English name becomes ap- 

 plicable to it, we are not acquainted. 



Hibiscus. This genus affords many fine species and 

 varieties of plants for the hot-house, besides others for 

 every department of the garden. The most popular in our 

 collections of the hot-house, is H. rosa sinensis, with its 

 varieties, which are magnificent, and flower profusely from 

 February to September. The single or original species is 

 also beautiful; the varieties are H. rosa sinensis rubro 

 plenus, double red; H. r. s. cdrnea plenus, double salmon; 

 H. r. s. variegdtus, double striped ; striped on the back of 

 the outside petals ; H. r. s. fldva-plenus, or cornea, double 

 buff; H. r. s. lutea plenus, double yellow, or rather sul- 

 phur. The plants grow freely, and produce their flowers
