Short Notes
BRI 182058, status annotated by author
Daviesia quoquoversus is a spreading shrub growing to 2 m high. The branchlets are arching, terete, hispid and ribbed. The phyllodes are spirally arranged along a branchlet. The green phyllodes are divaricate or reclinate, ovate, broad-ovate or cordiform in shape, long-acuminate and pungent at the apex, cordate or truncate at the base, 6 to 9 mm long and 4 to 11 mm wide and green. The mid-rib on the upper phyllode surface is prominent. The venation on the phyllodes is reticulate and usually conspicuous.
The inflorescences occur as racemes with 1 to 2 per axil. The bracts are ascending, broad-to very broad-obovate, with the uppermost bracts 0.3 to 0.5mm long and 0.3 to 0.6 mm broad. The pedicels are 3.1 to 6.2mm long. The flowers are of a typical pea form with a large petal at the back (the standard), two smaller lateral petals (wings) and two inner petals fused together to form the keel, and are 3.1 to 6.2 mm long. The green calyx is 2.8 to 3.1 mm long. The petals are yellow with red markings. The standard is shaped like an ellipse, 5.8 to 6.0 mm by 6.0 to 6.2 mm. The wings are 5.5 to 5.8 mm long by 2.3 to 2.5 mm wide. The sickle shaped keel at the base of the flower is 5.8 to 6.0mm long by 1.4 to 1.5 mm wide. The seed pods are flat, roughly triangular in shape and 9 to 10 mm long by 6 to 7 mm wide (Crisp, 1990; Barker, 1999)
Daviesia quoquoversus appears to be closely related to D. villifera, with which it shares a distinctive beaked, falcate keel-petal. However, D. villifera differs in bearing a hispid indumentum of straight hairs which are usually abundant all over the vegetative parts, including the lamina of the phyllode. Daviesia squarrosa and D. nova-anglica, although possessing a different shaped keel, have a glabrous phyllode lamina, like that of D. quoquoversus. In those species, however, the hairs are straight, quite unlike the bent and twisted hairs of D. quoquoversus (Crisp, 1990; Barker, 199).

Range derivation
Range derived from extent of the taxon's verified records
Daviesia quoquoversus occurs in open forest on sandy soil derived from sandstone. It has been recorded with Corymbia peltata, C. polycarpa, Eucalyptus baileyana and sclerophyllous shrubs and grasses (Banksia, Ricinocarpos and spinifex grasses) (Queensland Herbarium, 2012).
Little is known about the biology and ecology of this species. It flowers from July to September and its fruiting period is from September (Queensland Herbarium, 2012).
Threatening processes
There are no current threatening processes for Daviesia quoquoversus. Current possible threatening processes include inappropriate fire regimes and disturbance of habitat by weeds (e.g. lantana) (Barker, 1995).
Status notes
Daviesia quoquoversus is listed as Vulnerable under the Queensland Nature Conservation Act 1992.
Management recommendations
Management recommendations for Daviesia quoquoversus include: fire management to maintain intervals between fires longer than the minimum age at which the plants set seed, and; control or eradicate weeds, particularly lantana on sites where D. quoquoversus occurs (Barker, 1995).
