their continued healthful developments, and the profusion of flowers they will 
produce. 
They are propagated by cuttings of the half-ripened wood, which, although they 
do not strike very quickly, are nevertheless not difficult to root. Plant them in 
pots of sand, and cover with a glass, but do not subject them to a moist heat, or 
they will soon disappear : select a cool, and rather dry part of the propagating-house, 
take off the glass occasionally, to allow the cuttings to dry ; and in watering be careful 
never to wet the foliage, and allow them to stand exposed for a time until they are 
partially dried again before the glass is replaced. When struck, pot them off in 
sandy heath-mould, disturbing the roots as little as possible, and keep them in rather 
a close place until they have begun to grow ; then remove them to the greenhouse, 
and treat as before directed for the parent plants. 
The next group in order is Eudiosme^ ; it includes a number of African genera, 
chiefly from the neighbourhood of the Cape of Good Hope. In this tribe are some 
splendid ornamental plants. Calodendron capense is perhaps one of the handsomest 
deciduous flowering trees the Cape affords ; it grows from twenty to thirty feet high, 
and bears large panicles of rich flesh-coloured flowers. All the others are shrubs, 
varying in growth from one to three feet, with a habit not unlike Erica, and bearing 
white or rose-coloured flowers. The various species of Barostna, but especially 
crenata and punctata, are called by the Hottentots Bucku, The leaves are dried, 
powdered, and mixed with grease, and with this unpleasant-smelling unction they 
anoint their bodies. The names of the genera are Acmadenia, Adenandra, Aga- 
thosma, Barosma, Calodendron, Coleonema, Diosma, EuchcBtis, Empleurum, Gym- 
nonychium, Macrostylis, and Pachystigma. 
With the exception of Calodendron, which is a little difficult to propagate, all 
these genera are very easy of culture. To be successful with the former, the cuttings 
must be made immediately on the wood becoming matured; for — as the plant is 
deciduous — if the wood is allowed to become too old before the cuttings are made, the 
leaves fall before roots are protruded, and success is very doubtful. 
The soil in which the whole of the plants in this group will grow best, is sandy 
heath-mould, with a small portion of light turfy loam. 
Pot them after the manner of other plants with heath-like habit ; give plenty of 
drainage, and treat them in every respect like common greenhouse plants. 
Propagation is effected by taking off the extremities of the young shoots, and 
planting them in pots of sand under a glass, but without heat. 
Tribe 5 — Dictamne^e — has but one genus, Dictamnus, or Fraxinella, a hardy 
herbaceous plant, of the easiest culture in the open borders. 
Tribe 6 — RuTEiE — embraces Biebersteinia , Boenninghausenia, Haplophyllum,
