Habitat

Sophora fraseri is a subtropical shrub, that normally grows in wet sclerophyll forest and a range of rainforest types. It has been reported growing in hilly terrain on hillslopes at altitudes at altitudes from 60 to 660m, mostly shallow stony to shaly soils, of loam to clay texture derived from sandstone or basalt rocks. Associated species include: Corymbia citriodora, Eucalyptus carnea, E. microcorys, E. acmenoides, E. propinqua and Lophostemon confertus. The shrub appears to prefer growing along rainforest margins, in eucalypt forests in the vicinity of rainforests or in large canopy gaps in closed forest communities (Barker and Borsboom, 1997; Queensland Herbarium, 2012).

Description

Sophora fraseri is a softly pubescent, sparsely branched leguminous shrub, growing 1 to 2 m high. The leaves are pinnate and are 6 to 15 cm long with a petiole 10 to 20mm long. The leaves have 21 to 35 oblong to ovate leaflets 5 to 25 mm long by 3 to 10 mm wide, with entire margins, petiolules 1 to 2 mm long, with an obtuse or retuse apex. The flowers occur in terminal racemes, 5 to 13 cm long, with 5 to 10 mm long pedicels. The calyx is 4 to 6 mm long, the corolla is pale yellow and 9 to 15mm long. The pod is moniliform, indehiscent, 3 to 10 cm long, up to 8 mm in diameter, sparsely hairy, irregularly constricted between the seeds. There are 2 to 7 seeds, approximately 6mm long (Stanley and Ross, 1983; Harden, 2002).
Sophora fraseri is a fairly distinctive species with its pinnate leaves with numerous leaflets, yellow flowers, plump seeds and pods which are very constricted between the seeds, giving the appearance of a string of beads (QCRA/RFA, 2008).

Reproduction

Flowering of Sophora fraseri has been recorded in April and from late August to mid November. Fruiting has been recorded in January, April, July-August and November (Barker and Borsboom, 1997; Queensland Herbarium, 2012).

Threatening Processes

The main identified threats to Sophora fraseri are loss of habitat through clearing for agriculture and development; timber harvesting activities; weed infestation, such as Lantana (Lantana camara); grazing by livestock; inappropriate fire regimes as too frequent fire depletes the soil seed banks; and localised extinction of small populations (Forster et al. 1991; Barker and Borsboom, 1997).
