Flora of Denmark WA - Styphelia

Stpyhelia from the Greek styphos tough, harsh.

The following table lists the Styphelia species which are shown by Florabase to have been collected in Denmark Shire. The second column shows whether the species was included in the book Flora of the South West and under what name if different. If the species was described after Flora of the South West was published, the paper describing the species is noted. Where a species is not included in Flora of the South West I have endeavored to provide some sort of description after the table.

S. flavescens

When the book was published there were no collections identified as this species (which was then known as Leucopogon flavescens) in the area covered by the book. Two collections have since been so identified one of which is in Denmark Shire.

The following description is from Flora Australiensis by George Bentham (1868) vol. 4 page 212.

A shrub of 2 to 4 ft. (60–120cm), with erect branches, minutely pubescent, the foliage of a pale yellowish hue when dry. Leaves rather crowded, erect, oblong-linear, obtuse or with a minute callous point, flat or nearly so, contracted into a very short petiole, 1/4 to 1/2 in. (6–12mm) long. Flowers axillary, solitary on an exceedingly short pedicel, the subtending bracts and rudimentary flower of the other species entirely wanting. Bracteoles broad, ciliate, about half as long as the calix. Sepals under 1 line (2.5mm) long, almost acute, with thin, ciliate margins. Anthers attached above the middle, obtuse, without sterile tips. Hypogynous scales shortly acuminate, free or slightly cohering. Ovary oblong, 2-celIed; style rather long. Fruit oblong, flat, nearly 3 lines (7.5mm) long, with 3 to 5 raised ribs on each side, and contracted into a stipes at least as long as the calyx.

S. inframediana

It is likely that the only areas this species occurs within Denmark Shire are Mount Lindesay and Little Lindesay (an iNat observation further west has been made since I wrote this). It mainly flowers April to June. Shrub to about 90cm, single stemmed at ground level. Leaves 3.5–9mm long 1–2.5mm wide, convex (upper surface rounded) top surface shiny, lower surface paler, matt and with clearly visible veins, sharp point on tip. Flowers pendulous, corolla tube shorter than lobes but generally longer than sepals, style exserted well beyond the erect portion of the corolla lobes.

S. madida ssp madida

Flowers mainly January to April. Shrub to about 1.5m, single stemmed at ground level. Leaves 8–21 mm long, 0.8–3.8 mm (ususally less than 1.8mm) wide, convex (upper surface rounded), sharp point on tip. Flowers pendulous (unlike S. propinqus and S. racemolus where they are spreading), corolla tube shorter than lobes but generally longer than sepals, style exserted beyond the erect portion of the corolla lobes.
