parentage (C. speciosissimus at d C. grandiflorus) being half a night 
bloomer already, remaining open three nights, and if shaded from 
bright sun two days, so that recrossing with C. grandiflorus may 
not only add another part to .vards making it a true night flowerer 
but may have the scent transmitted to C. Maynardi. 
Raising seedlings, although so interesting, is a somewhat slow 
process, as, provided they thrive well, four or five years must 
elapse before any flowers appear, and in many cases a more ex¬ 
tended length of time is necessary before the plants can be induced to 
that in spite of all endeavours to induce it to bloom it persistently 
refuses to do so. Many more varieties of Cereus might be noticed, 
and they are all more or less beautiful, and well worthy of more 
extended cultivation. 
The Echinocereus should receive a passing notice ; some of the 
varieties being very beautiful when in bloom, and when not in 
flower their remarkable appearance are always objects of attraction. 
E. Blanckii is very handsome, and also very free both in habit of 
growth as well as flowering. E. Fendleri is a very desirable sort to

bloom. The seedlings mentioned above number between 200 and 
300, and during the last four seasons we have had the pleasure of 
seeing many of them bloom. They include several new shades of 
colour, and the majority of them are considered to be improve¬ 
ments on the old forms, having larger blooms of more substance, 
an 1 are altogether a most interesting young family. Another very 
beautiful Cereus is C. tuberosus, a variety obtained from the Con¬ 
tinent a few years ago. It bears a most beautiful flower of bright 
rosy pink colour, and is sweet-scented. It is of small cylindrical 
growth, and is well worthy of notice. Amongst others might he 
named C. canaicans, which, although being in the collection some 
thirty years, is only remarkable for its slowness of growth, and 
grow, and it is said that in suitable positions is quite hardy, as are 
some others of the Echinocereus. The blooms of Echinocereus 
are more lasting than most other Cactus flowers. Some of them 
will open every day for a week, and in some instances loilger than 
that. 
Echinocactus, known as the Hedgehog Cactus, contains some 
very remarkable forms of growth and very beautiful flowers of 
various colours, and a few should be grown in every collection of 
plants of this description. Echinopses and Mamillarias are closely 
allied to the above, and contains amongst their number some of the 
most curious forms of vegetable life. These all thrive in a satis¬ 
factory manner if potted in a thoroughly porous soil. The pots
