Scientific name: Notelaea lloydii

Common name: Lloyd's Olive

Conventionally accepted as Notelaea lloydii (CHAH 2010).

Lloyd's Olive is a shrub, growing to 1–4 m in height with many smooth, pale grey barked stems arising from the base. Stems are approximately 2–4 cm in diameter. The hairless leathery leaves are linear or slightly sickle-shaped, 7–14 cm long and 2–5.5 mm wide with the main veins clearly visible, and slightly raised on the upper leaf surface. Up to 20 flowers grow in groups in leaf axils (upper angle between leaf stalk and stem). Flowers are pale yellow or cream, up to 2 mm in diameter, and on stalks that are 3–5 mm long. The fruits are spherical to ovoid, 5–8 mm in diameter and consist of a hard woody nut with a thin, dark blue skin (Guymer 1987; Halford 1998).

Lloyd's Olive is known from eight sites at five locations within south-east Queensland (SE QLD). The following is a list of the species' known locations (Guymer 1987; Qld DNR 2000):

  • Mt Crosby area, on the western outskirts of the city of Brisbane
  • the Boonah district, south-west of Brisbane
  • Moggill State Forest (SF 494), west of Brisbane
  • State Forest 637 (unnamed)
  • Moogerah Peaks National Park, approximately 100km south-west of Brisbane.

The extent of occurrence of Lloyd's Olive is approximately 3700 km² (Qld CRA/RFA Steering Committee 1998).

There is no quantitative data available on population sizes. However, Lloyd's Olive has been reported as being rare or only a few plants seen at collection sites (Queensland Herbarium n.d.).

The species occurs on undulating to hilly terrain either in moist gullies or on gentle to steep dry slopes, but is rarely found on rocky outcrops. Soil types are mostly shallow, well drained and stony to very rocky in texture (Guymer 1987; Qld CRA/RFA Steering Committee 1998).

Lloyd's Olive is found in the ecotone between eucalypt open forests and vine thickets (Guymer 1987) at 80-480 m above sea level (asl) (Qld CRA/RFA Steering Committee 1998). The more frequent tree species recorded with this species are Narrow-leaved Ironbark (Eucalyptus crebra), Spotted Gum (Corymbia maculata), White Mahogany (E. acmenoides), Lemon-scented gum (C. citriodora) and Curracabah (Acacia concurrens) with associated trees and shrubs of Kurrajong (Brachychiton populneus), Red Ash (Alphitonia excelsa), Brown Salwood (A.aulacocarpa), Burra (A. falcata) and Ebony (Diospyros ferrea var. geminata) (Guymer 1987; Qld CRA/RFA Steering Committee 1998).

Adult plants are capable of resprouting from the base after fire has killed the above-ground structures (Bird pers. comm. in QDNR 2000). Lloyd's Olive is believed to form a lignotuber. It is estimated that the plant requires at least five years between fires to successfully regrow to flowering stage (Qld CRA/RFA Steering Committee 1998; Harris pers. comm. in QDNR 2000).

Lloyd's Olive is closely related to the Native Olive (N. microcarpa), from which it is recognised by its linear leaf shape, multi-stemmed habit and height to 4 m. Comparatively, the Native Olive has linear-lanceolate leaves, and reaches a height to 15 m (Qld CRA/RFA Steering Committee 1998).

The main threat to Lloyd's Olive is habitat loss and degradation due to urban development. The current fragmented, rare and isolated nature of the species means it is more vulnerable to loss of remaining habitat.

In addition, inappropriate fire regimes are a potential threat to the species as frequent hot fires are known to kill young seedlings and suppress recruitment. Mature plants, however, can survive fires.

Road maintenance activities potentially threaten the species as some populations grow on roadsides. 

Weed invasion is a potential threat, especially by Lantana (Lantana camara). This weed is capable of invading forest margins and smothering plants which reduces light for the Lloyd's Olive and increases fire fuel loads (Halford 1998; TSSC 2008aal).

The Department of Sustainability, Environment, Water, Populations and Communities (DSEWPaC) outline the following actions for protection of Lloyd's Olive in the Approved Conservation Advice for Notelaea lloydii (TSSC 2008aal):

Habitat Loss, Disturbance and Modification

  • Monitor known populations to identify key threats.
  • Identify populations of high conservation priority.
  • Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary.
  • Ensure road widening and maintenance activities (or other infrastructure or development activities) involving substrate or vegetation disturbance, in areas where Lloyd's Olive occurs, do not adversely impact on known populations.
  • Minimise adverse impacts from land use at known sites.
  • Investigate formal conservation arrangements, management agreements and covenants on private land, and for crown and private land investigate inclusion in reserve tenure if possible.

Invasive Weeds

  • Develop and implement a management plan, in conjunction with existing local and national weed management plans, for the control of Lantana.
  • Identify and remove weeds in the local area, which could become a threat to Lloyd's Olive, using appropriate methods.
  • Manage sites to prevent introduction of invasive weeds, which could become a threat to the species, using appropriate methods.
  • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on Lloyd's Olive.


  • Develop and implement a suitable fire management strategy for Lloyd's Olive.
  • Provide maps of known occurrences to local and state Rural Fire Services and seek inclusion of mitigative measures in bush fire risk management plans, risk register and/or operation maps.

Conservation Information

  • Raise awareness of Lloyd's Olive within the local community.
  • Maintain liaisons with private landholders and land managers of land on which populations occur.

Enable Recovery of Additional Sites and/or Populations

  • Undertake appropriate seed collection and storage.
  • Investigate options for linking, enhancing or establishing additional populations.
  • Implement national translocation protocols (Vallee et al. 2004 cited in TSSC 2008aal) if establishing additional populations is considered necessary and feasible.

Management documents for the Lloyd's Olive can be found at the start of the profile. Other documents relevant to the species include:

  • Weeds of National Significance: Lantana (Lantana camara) Strategic Plan (ARMCANZ 2001a).
  • Management Program for Protected Plants in Queensland 2011-2015 (Qld DERM 2011b).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
