It is a biennial green-house plant, and, of course, only to be raised from seeds, which we are sorry to find have not ripened in this country, though they are said to do so in France. [220] ERICA CERINTHOIDES. HONEYWORT-FLOWER'D HEATH. _Class and Order._ OCTANDRIA MONOGYNIA. _Generic Character._ _Cal._ 4-phyllus. _Cor._ 4-fida. _Filamenta_ receptaculo inferta. _Antherae_ bifidae. _Caps._ 4-locularis. _Specific Character and Synonyms._ ERICA _cerinthoides_ antheris muticis inclusis, corollis clavatis grossis, stigmate incluso cruciato, foliis quaternis. _Linn. Syst. Vegetab. ed. 14. Murr. p. 368._ _Ait. Kew. V. 2. p. 22._ The _Erica cerinthoides_ is one of the most magnificent and shewy of the genus, grows wild at the Cape, from whence it was introduced to the royal garden at Kew, by Mr. MASSON, in 1774; it is the more valuable, as it flowers during most of the year: its blossoms are found to vary from a deep to a very pale red. It is a hardy green-house plant, and usually propagated by cuttings. To have this beautiful tribe of plants in perfection, they must be kept in pots proportioned to their size, filled with that kind of bog earth in which our British heaths grow spontaneously, finely sifted; to which it may be necessary sometimes to add a third part of the mould of rotten leaves, or choice loam, partaking more of a clayey than a sandy nature: we must be careful not to let them suffer for want of water in dry hot weather, as such an omission, even for one day, may be fatal; and to give them as much air as possible at all times when the weather is mild. [Illustration: _No 220_] [221] IPOMOEA COCCINEA. SCARLET IPOMOEA. _Class and Order._ PENTANDRIA MONOGYNIA. _Generic Character._ _Cor._ infundibuliformis, _Stigma_ capitato-globosum, _Caps._ 3-locularis. _Specific Character and Synonyms._ IPOMOEA _coccinea_ foliis cordatis acuminatis basi angulatis, pedunculis multifloris. _Linn. Syst. Vegetab. ed. 14. Murr. p. 204._ _Ait. Kew. V. 1. p. 215._ CONVOLVULUS coccineus, folio anguloso, _Plum. Amer. 89. t. 103._ QUAMOLCIT americana, folio hederae, flore coccineo. _Comm. rar. 21. t. 21._ The _Ipomoea_ is very nearly related to the _Convolvulus_, one principal difference consists in the different form of its stigma, which is globular, like that of the Primrose; whereas in the Convolvulus it is divided into two substances, as is obviously shewn in the _Convolvulus arvensis_ and _sepium_, but all the plants of these two genera have not this character marked with equal strength. The present species is a twining plant, will run up a stick to the height of six, eight, or ten feet, and produce an abundance of flowers, of a rich orange colour tending to scarlet, which renders it one of the most ornamental annuals cultivated in our gardens, into which it is not as yet generally introduced, though cultivated by Mr. MILLER, in 1759.
