=ÆCHMEA= (from _aichme_, a point; in reference to the rigid points

on the calyces, or flower-envelopes). Including _Pironneaua_. ORD.

_Bromeliaceæ_. Very handsome stove plants. Flowers scapose, panicled;

perianth six-cleft, three outer segments sepaloid, longer than the

three inner or petaloid ones. Leaves ligulate or sword-shaped,

sometimes with marginal spines. The species thrive best in a

well-drained compost of rich fibrous loam and leaf mould. They like

plenty of light, which may be afforded by standing them on inverted

pots, so as to raise their heads well up above the surrounding plants.

Propagation: When the flower-spikes, which are sent up from the heart

or crown of the plant, die away, suckers or offsets are produced near

the base, and from these other flowers appear the year after. If large

plants are desired, these suckers should be left to grow and spread

around; but to produce single plants, the suckers must be taken off

and potted singly, in sharp soil, and then stood where they can get

a moist heat till rooted. To enable them to do this it is necessary

to strip off a few of the lower leaves, and trim the bottom with a

sharp knife, in order that it may heal over and callus more readily

than it otherwise would. When rooted, the plants may be shifted into

larger-sized pots; but for single crowns 32-sized pots are large

enough, as the plants, being epiphytal in their nature, do not require

much soil or any great supply of water, except when growing freely or

sending up their flower-spikes. In winter, they should be kept rather

on the dry side, to induce partial rest; and an important point is to

see that water is not allowed to lie for any length of time in the

crown of the plant, as when that is the case it is likely to cause them

to rot.
