Anthurium watermaliense

Anthurium watermaliense can be recognized by the ovate-triangular to sub-3-lobed leaf blades, the broad, frequently dark purple spathe, green to purple, stipitate spadix with long-exscrted stamens, and yellow to orange berries.

Araeococcus flagellifolius

Araeococcus looks more like an exotic grass than the bromeliad it really is.

Arfeuillea arborescens, Koelreuteria arborescens

It produces fragrant small flowers with a very strong perfume. The compound leaves are spirally arranged around the branches.

Arisaema speciosum

Arisaema speciosum has medium-sized chocolate-maroon coloured spathes with white stripes arranged in a vertical fan-shape. The tip of the spathe hood is elongated and often droops down and together with the long attenuated spadix appendage gives this Arisaema one of its common names, the Double Whip Cobra Lily. Before the spathe fully opens it often resembles the beaked silhouette of a long-beaked bird.

The leaves are dramatically exotic and have three large segments that are heavily rugose underneath and margined with red.

Arisaema tortuosum, Arum tortuosum

Arisaemas resemble carnivorous plants, but in fact they attract flies and other insects as pollinators, not food. Their leaves are divided into three or more leaflets. Their fascinating "flower" a pulpit-like hooded spathe enclosing a fleshy, erect spadix usually rises in spring. Scarlet berries by late summer or autumn enclose seeds that are scattered by birds and other creatures.

They prefer a rich but well drained neutral to acid soil that does not dry out in the growing season.

The plant contains calcium oxylate crystals. These cause an extremely unpleasant sensation similar to needles being stuck into the mouth and tongue if they are eaten but they are easily neutralized by thoroughly drying or cooking the plant or by steeping it in water. Tuber - it must be thoroughly dried or cooked before being eaten. The roots are buried in masses in pits until acetous fermentation takes place, they are then dug up, washed and cooked, by which means their acrimonious principles are in part dispersed.
