All the species of Aerides may be grown in pots, crocked from one-half
to two-thirds of the way up, the old stems of the plants, when long,
being placed in the pots before the crocks are filled in. The surface
should be of good living Sphagnum-moss, and the plants should be
liberally watered from the end of February or beginning of March until
autumn, when the supply of water should be restricted according to the
condition of growth of the plants. Those which have finished their
growth and are not showing new leaves in the centre should be given the
least supply, but it is not advisable to dry any off completely, unless
for some reason they have to be kept comparatively cool throughout the
winter, when they are safest if kept tolerably dry. The smaller species
may be grown in baskets with advantage when convenient--indeed, the
true epiphytal character of the whole genus would suggest that method as
the better, but experience has proved that they may be equally well
grown in pots. The warm house, or warm end of the intermediate house,
suits all the species, but _A. japonicum_ may be grown in the cool
house. Most of the species have white and rose-coloured flowers, and
they are very fragrant.

_A. odoratum_, one of the oldest of garden Orchids, is one of the best
and most free-growing species. _A. crispum_, _A. crassifolium_, _A.
Fieldingii_, _A. Houlletianum_, _A. falcatum_, _A. Lawrenciae_, _A.
multiflorum_ in its many forms, _A. quinquevulnera_, _A. suavissimum_,
and _A. virens_ are the best for amateurs.

_A. cylindricum_ and _A. Vandarum_ have terete leaves like _Vanda
teres_, the former with white flowers, having a fleshy yellow and red
lip, and the latter, which is more membraneous in substance, being
white. Although often confused with each other in gardens, there is
little resemblance between these two species.

~Aganisia.~--This genus thrives best in Orchid pans in the intermediate
house, in the ordinary compost used for epiphytal Orchids, with an
addition of leaves. Place the plants in a moist situation.

_A. caerulea_ is of trailing habit, and has blue and white flowers. _A.
ionoptera_ is white and purple, and _A. lepida_ white.

~Angraecum.~--A large genus chiefly from Africa and Madagascar, and
requiring similar treatment to Aerides. Botanists have divided the genus
into Aeranthus, Listrostachys, Mystacidium, &c., but for garden purposes
the one generic title suffices. The flowers of nearly all th
