SYNOPTIC K E Y TO AUSTRALASIAN ASTELIADS
1
Main stem and leaves brittle, leaf lamina breaking cleanly if folded transversely towards the adaxial side; leaf sheath open upwards forming a water-holding container, the long scales confined to a well defined zone at the extreme base; abaxial leaf scales with peltate platelets; perianth tube deeply cupshaped, membranous; ovary trilocular; funicle hairs long and mucilaginous
Main stem and leaves tough with strong fibres except in very small plants; leaf sheath usually keeled, in old leaves rarely containing water, long scales over whole sheath, occasionally very sparse; abaxial leaf scales without peltate platelets; perianth tube, if membranous, so short as to be hardly visible, if appreciably long or deep, then ± fleshy; ovary tri- or unilocular; funicle hairs, if present, very short
2
Ovary unilocular; seeds ± globose to terete, with thickened or projecting funicle
Ovary trilocular; seeds usually with some flattened faces; funicle little if at all thickened
4

Leaf with a close group of 3 lateral nerves extending well above mid-length; outer tepals externally scaly to tip; fruit red with distinct style; ♀ inflorescence stiffish; usually terrestrial and tall
Leaf without a close group of 3 lateral nerves in upper half; outer tepals glabrous at tip; fruit yellow-green to dark brown; style very short; ♀ inflorescence lax; usually epiphytic, but often growing on ground
8
Inflorescence many-branched, standing well up within or drooping out from tuft of leaves; fruit white flushed with magenta, seated on membranous remnants of perianth; seeds not shining, with many flat faces meeting along rather sharp edges; leaf just above the sheath tightly folded about a strong keel, the lamina covered adaxially with a silvery pellicle, abaxially showing a number of subequal nerves
Inflorescence few- to many-branched, standing stiffly erect, the peduncle usually hidden within the tuft of leaves; fruit strong orange to yellow, ± flushed with red, the persistent perianth ± fleshy and brightly coloured; seeds shining, rounded, inner faces ± flattened by mutual pressure; leaves various, but none with the same combination of characters as in A. banksii

Inflorescence much reduced, racemes represented mostly by only 1-2 flowers; fruit obconic, fleshy proximally with loculecavities confined to distal half
Inflorescence with definite racemes, though sometimes congested; fruit broadest about or below the middle, locule cavities in proximal part
17
Leaf lamina narrow, mostly ± 1 cm wide, dull brown adaxially, nerves on each side of midrib usually <6; habit diffuse and grasslike owing to lateral shoots developing in axils of many leaves; panicle simple, each spathe subtending only 1 raceme; fruit nearly twice as long as broad
Leaf lamina broader, brownish adaxially only on extreme margin, nerves on each side of midrib usually > 6; leafy tufts well defined, lateral shoots mostly developing only in axils of 1—3 subfloral leaves; panicle usually more compound; fruit less elongate
