CERATIOLA. 



A little-grown, half-hardy, Heath-like shrub (ord. 

 l'jn]>ctracea!), of evergreen habit and producing 

 brownish flowers in June, followed by yellow 

 berries. The needle-shaped leaves are about i" 

 long and generally close together. It likes sandy 

 peat soil, and is propagated by cuttings placed in 

 slight heat, with a bell-glass over them. 



Only Species : 

 ericoides, 2', Je., br. 



CERATOLOBUS. 



A small genus (ord Palmre) of slender, graceful 

 Palms, seldom grown but very beautiful, glaucescens 

 being especially useful as a table plant. They 

 require a stove temperature and a good compost of 

 loam and peat. 



Principal Species : 



concolor, 6'. glaucescens, 10', Ivs. up 



to 2' loug. 



CERATONIA. 



This evergreen tree (ord. Leguminosae) has great 

 economic value in the lands to which it is indig- 

 enous. It produces brown pods of sweet mealy 

 matter, which has medicinal properties. They are 

 eaten largely with a view to improving the voice, 

 and also used in the preservation of other fruits. 

 The horses of the British army were fed upon them 

 in the Peninsular War. They have been called the 

 St. John's Bread, from the supposition that they 

 were the locusts upon which St. John the Baptist 

 fed in the wilderness. They are also supposed to 

 be the "husks" of which the prodigal son was 

 obliged to eat. The seeds are said to have been 

 the original carat weights used by jewellers. The 

 tree succeeds best in the greenhouse, but is hardy 

 in favoured localities. It thrives best in fibrous 

 loam and sand, and may be propagated from 

 cuttings of ripe wood in sandy soil under a bell- 

 glass. 



Only Species : 



Wliima, !.">', Sep., yel., red. (The Carob.) 



CERATOPETALUM. 



Tin-so are the red gum trees (ord. Saxifrages) of 

 Xew South Wales, and should be grown in rich 

 loam and sand in the greenhouse. Cuttings root 

 readily in sandy soil under a bell-glass.

Principal Species :

CERATOPTERIS. 



A most remarkable aquatic Fern (ord. Filices), 

 an annual, or at most biennial. It is best grown 

 in good loam, the pot being wholly submerged in a 

 tank of warm water in a stove temperature. There 

 is no difficulty in propagating the species, either 

 from spores or by means of the young plants that 

 form on both fertile and unfertile fronds. It is an 

 elegant and distinct Fern, popularly known as the 

 Water Elk's Horn. 



Only Species : 



thalictroides, 2J', fronds bright grn. 



CERATOSTEMA. 



These greenhouse evergreen shrubs (ord. Vac- 

 ciniacex) thrive best in peat and sand, and may 

 be propagated by cuttings inserted in sandy soil 

 beneath a bell-glass. 



Principal Species : 



hirsutum, 4', My., sc. 

 longiflorum, 3', My.,crim. 



spcciosum, 3', Je., red, 



yel. 



CERATOSTIGMA. 



An obscure genus of greenhouse or hardy per- 

 ennial herbs or shrubs (ord. Plnmbagincic). The 

 species mentioned below is the only one of note ; 

 it will grow in any fairly good garden soil, and 

 may be increased by root division. 



Principal Species : 



plumbaginoides, 1', Oct., hdy., vio. (syn. Plumbago 

 Larpentie). 



CERATOTHECA. 



The species in cultivation is a half-hardy annual 

 (ord. Pedalinese), but it is best grown in the green- 

 house, unless a favoured position can be afforded 

 out of doors. It is raised from seeds, and prefers 

 a sandy loam. 



Only Cultivated Species : 

 triloba, 3', Sep., vio., bl. 



CERBERA. 



Stove shrubs and trees (ord. Apocynaceze), 

 thriving in fibrous loam and leaf mould. Cuttings 

 in sand under a bell-glass over bottom heat root 

 with proper care. Some are poisonous. 



Principal Species : 

 Odollum, 20', Jy., wh. Tanghin, 20', Je., pk. 



CERCIDIPHYLLUM. 



In the south of England and Ireland this shrub 

 (nrrf. Magnoliacea 1 ,) is hardy, but in cold districts 

 it should have greenhouse protection. Propagation 

 by cuttings. 



Only Species : 



japonicum, 5'. sum., grn. 



CERCIS. (JUDAS TREE.) 



Singularly pretty hardy deciduous trees (ord. 

 Loguminosse), which are less frequently grown 

 than they deserve. They are suitable for either 

 the garden or the shrubbery, and are of much effect 

 with their branches crowded with flowers before 

 the leaves appear. They are raised from seeds 

 sown in sandy soil in March or April, or by layers. 



Principal Species :
