1	"Leaves flat or convex, margins often recurved"	3
2	"Leaf-bases conspicuously cordate, ± stem-clasping at base, palmately 5–7-veined; localized in the north-west on mallee sandhills"	"Leucopogon costatus"
2	"Leaf-bases tapered to obtuse, rarely slightly cordate, ± parallel-veined; very widespread, except in further north-west"	"Leucopogon virgatus"
3	"Procumbent shrubs; leaf margins with relatively long, thready hairs, leaf surfaces otherwise glabrous; uncommon species of moist subalpine or alpine, treeless heaths and grasslands"	"Leucopogon pilifer"
3	"Erect shrubs; leaves glabrous, or with hairs either short (less than 0.5 mm long) or not confined to margins"	4
4	"Corolla lobes distinctly shorter than to subequal to tube; montane to subalpine shrubs"	"Leucopogon gelidus"
4	"Corolla lobes longer than or equal to tube; lowland or lower montane species"	5
5	"Leaves small (up to 12 mm long) with margins recurved to some extent, or if flat, then leaves spirally twisted to some degree"	6
5	"Leaves at least 12 mm (and normally 15 mm) long, more or less flat, never spirally twisting"	9
6	"Leaf surfaces pubescent; sepals distinctly hairy, obtuse to broadly acute"	7
6	"Leaves glabrous, or very shortly ciliate on margins only; sepals glabrous or nearly so, acute"	8
7	"Flower spikes very short (up to c. 7 mm long), usually 2–5-flowered; sepals 2.2–3 mm long, dark-tipped; ovary 2- or 3-locular; leaves to 6 mm long; mainly eastern, with outlying populations in and near the Brisbane Ranges"	"Leucopogon microphyllus"
7	"Flower spikes generally 1 cm long or more, mostly 7–13-flowered; sepals 1.6–2.2 mm long, not dark-tipped; ovary 3–5-celled; leaves commonly 1 cm long or more; Grampians only"	"Leucopogon thymifolius"
8	"Leaves usually with margins recurved, not spirally twisted, usually widely spreading or reflexed, at least on lower parts of branches; eastern"	"Leucopogon collinus"
8	"Leaves flat in cross-section, but spirally twisted to some degree, erect to ascending on stem; western"	"Leucopogon glacialis"
9	"Leaves rather rigid, prominently lined on both surfaces by 3–7 translucent veins; endemic on mountains of the Grampians and nearby ranges to the east"	"Leucopogon neurophyllus"
9	"Leaves mostly thin, the veins neither particularly conspicuous nor translucent; mostly foothills and near coasts, not in Grampians"	10
10	"Leaves distinctly coumarin-scented; flowers 15 or more in spikes mostly longer than 30 mm; slender shrubs to c. 2 m high, of near-coastal heaths"	"Leucopogon australis"
10	"Leaves not coumarin-scented (practically odourless); flowers mostly fewer than 15 on spikes mostly less than 30 mm long; shrubs often with spreading branches, often higher than 2 m"	11
11	"Leaves usually widest about midway; flowers distinctly separated on spike; ripe fruit red (rarely merely yellowish); ovary 2 (rarely 3)-locular; lowland forests, rarely truly coastal"	"Leucopogon affinis"
11	"Leaves widest above midway; flowers crowded on spike; ripe fruit white; ovary 4–5-locular; mainly coastal"	"Leucopogon parviflorus"
