TUE FLORAL WORLD AND GARDEN GUIDE. 
273 
specimens about a foot in height. A few of the Aloes are desirable ; 
the best for a small collection being A. glauca, A.mitrceformis, and A. 
rahro-cincta. 
The Beaucarneas are of comparatively tall growth, with grace- 
fully drooping leaves. In some respects they may be likened to a 
slender-growing, green-leaved Dracicna, excepting that tlie leaves 
droop in a very graceful manner. B. glauca, and B. recurvata are 
both good, but the latter is the most desirable of the two. Bona- 
j)artea juncea is another very elegant-growing subject, with deep 
green leaves. 
Several of the free-growing Cactus are desirable, for they have a 
distinct appearance, and the majority bloom very freely. They differ 
considerably in character, and the most distinct and desirable are— 
Cereus azureus, G. Dr. Andre, C. ehurneus, G- flagelUformis, G. gran- 
dijlorus (commonly known as the night-blooming Cactus), C. 
MDonaldi, C. peruvianus, G. ScJiotti, G. speciosissimus, and C. Vic- 
toria. Cotyledon Iloolceri and G. marginatum are both distinct and 
good. Crassula Gooperi, G. ericoides, G. lactea, C. perfoliata, and 
C. verticillata present us with a distinct type of vegetation, and 
are very desirable in collections. 
Echeverias are most useful, and, from the large number in cul- 
tivation, I have selected the undermentioned as being the best, 
namely, E. atropurpurea, E. Californica, E. macrophylla, E. metalliea, 
E. metalliea glauca, E. navicularis, E. pubescens, E. pulverulenta, 
very beautiful, but rather scarce and expensive, E. retusa, E. retusa 
major, E. retusa splendens. Retusa and its varieties are all valuable 
for flowering in early spring. Euphorbia splendens is useful for 
training up pillars and walls. The Kalosanthes bloom most pro- 
fusely with ordinary management. The most showy are — K. 
coccinea superba, K. Madame Celeste Wynans, and K. Otto Deines, 
all of which have richly-coloured flowers. Kleinia repens is inte- 
resting and ornamental. 
The Mesembryauthemums are remarkable for the peculiarities of 
their growth and their showy flowers. The most useful are — M. 
hlandum, M. coccineum, M. cordifolium variegatum {useful for baskets), 
M. formosum, M. polyantlium, and M. tigrinum. Mamillaria elon- 
gatais very striking in appearance, and in every way desirable. 
The Optunias are valuable for the variety they afford, and a few 
should be grown. The most distinct are — O. clavarioides, 0. cylin- 
drica, 0. imbricata, 0. Bafinesguiana, O. tunicata ; FacJiypliiton 
bracteosum is very beautiful, and should be in every collection. 
A few of the Sedums are useful, especially S. Sieboldi, 8. Sieholdi 
variegata, and 8. spectabilis purpureum. Rocliea falcata is very 
interesting in appearance at all times, but when in bloom in the 
autumn it is exceedingly beautiful. The Sempervivums, which can 
be the most strongly recommended, are — 8. azoideum variegatum, a 
neat, small grower, forming miniature trees. 8. arboreum, a tall 
grower, forming bushes several feet in height. 8. arboreum varie- 
gahim, a beautifully variegated variety of the preceding, which 
should be one of the first to be purchased. 8. arboreum atro- 
purpureum has dark purplish leaves when the plants are fully exposed 
Sepetmber. 18
