Yandanooka Mallee A mallee to 5m tall, erect or spreading, with smooth grey bark on the upper parts but with the basal bark persistent as peeling flakes. The juvenile leaves are dull and bluish in colour. The pith of the branchlets is glandular. The adult leaves are up to 1.5 cm wide and 9 cm long, lanceolate to sickle-shaped, green in colour and glossy. The vein network is dense and there are numerous oil glands. The inflorescences have up to 13 flowers, and have peduncles up to 16 mm long. The buds are 10 x 4 mm long, the operculum is cylindrical to conical. It is the same width as the hypanthium at the join on the mature buds. The fruit has a short stalk and is conical to cup-shaped, with a thin rim, a descending disc and 3 or 4 valves below the level of the rim. The seeds are pale grey-brown, almost spherical or cuboid in shape. This species is similar to
shaped operculum, which is narrower than the hypanthium. It is also related to E. accedens which is a tree with smooth, powdery bark. There is some variation in E. crispata in the form of buds and fruit and in the overall appearance. Both E. arachnaea and E. accedens occur with the species at most populations except one which has been partially cleared. It is thought that E. crispata may be of recent hybrid origin with these species as parents. Flowering Period: April-June Distribution and Habitat in the Moora District Occurs in the Yandanooka-Eneabba area and south to Boothendarra, a range of ca. 90 km. A total of less than 150 plants have been estimated and only two populations occur on conservation reserves, one of ca. 30 plants, the other at present known from one plant. E. crispata grows on clayey soils of shallow gullies, or on lateritic or granitic breakaways and slopes. Associated species include Eucalyptus arachnaea, E. accedens, E. wandoo, Santalum acuminatum, Allocasuarina campestris and Melaleuca sp.

(1988a). 61 Eucalyptus dolorosa Brooker & Hopper MYRTACEAE Dandaragan Mallee A low mallee to 2.5 m tall with stout stems and rough grey bark on the older stems. The juvenile leaves are broadly falcate, light bluish-grey in colour. The adult leaves are slightly glossy, green in colour, lanceolate to falcate, 10 x 2 cm. They have a moderately dense vein network and numerous oil glands. The inflorescences are axillary, but are clustered at the leafless ends of branchlets, appearing apparently terminal. There are 7 flowers in each, the buds have pedicels up to 1 cm long, and are rhomboid in shape, 9 x 6 mm with a slightly beaked operculum. The stamens are very numerous. The fruits have stalks to 7 mm long, and are cup-shaped to globose, 1 x 1.4 cm, with four valves. The seeds are brown, pyramidal and winged. This species is distantly related to Eucalyptus todtiana and E. lateritica, but differs in the small falcate leaves, apparently terminal inflorescences, long pedicels and glaucous juvenile leaves. The winged seed places the species in this group which also includes
in the late Pleistocene period. Flowering Period: March Distribution and Habitat in the Moora District Known from a single population on the slopes and summit of a lateritic hill east of Cataby. The population comprises eight ‘clumps’ over a few hectares on private property, which has been left uncleared by the owners for soil and nature conservation. Although the species has flowered each year for four years following its discovery in 1987, it was not found in fruit until February 1991. It grows in mallee heath in association with Eucalyptus gittinsii, E. pluricaulis and E. abdita amongst massive ironstone blocks over low scrub with associated species including Hakea lissocarpha, H. undulata, H. obliqua, Calothamnus quadrifidus, Acacia pulchella and Scholtzia sp.

Eneabba Mallee Eucalyptus impensa was found at the type locality in 1987, but was not seen in flower until July 1991. It is a straggling mallee to 1.5 m tall, with smooth stems, which are grey over pale copper in colour. The shoots of the new growth are green, not glaucous. The leaves on the mature plant are pale green to yellow-green (not glaucous), on short, stout petioles to 1 cm long. They are usually opposite, ovate in shape, to 14 x 8 cm. The inflorescence is single-flowered, in the axil of a leaf, the flower with a thick peduncle to 2 cm long. The bud has a hemispherical hypanthium and beaked operculum, which is slightly ribbed. It is up to 5 x 2.5 cm, including the pedicel length. The flowers are pink in colour. The fruit is sessile on a thick pedicel to 2 cm long. It is hemispherical in shape, to 2.5 x 6 cm, with a conspicuous raised disc and five exserted valves. The seeds are brown and asymmetrically pyramidal in shape. The large fruits are similar to those of E. macrocarpa, but E. impensa is distinguished by the non-glaucous leaves which have short stalks. It is also a much smaller mallee than E. macrocarpa. Flowering Period: June-July Distribution and Habitat in the Moora District E. impensa is restricted to six populations with a total of less than eighty individuals growing over a range of ca. 3 km to the south-east of Eneabba. Five of these populations are on a nature reserve and the sixth on private property. The species has also been recorded from ca. 70 km to the south-east of the known populations, but was not refound during this survey, although remnant woodland of Eucalyptus macrocarpa occurs at the recorded location. It grows in very open shrub mallee over low heath on grey, gravelly sand on undulating plains and low breakaway slopes. This species occurs in association with other mallees,
other species including Xanthorrhoea sp., Hakea incrassata, H. conchifolia, H. obliqua, Banksia grossa, B. chamaephyton, B. lanata, Calothamnus quadrifidus and Verticordia grandis.

Cooper (in Brooker and Hopper 1993). 65 Eucalyptus johnsoniana Brooker & Blaxell MYRTACEAE Johnson's Mallee A small, spreading mallee to 2 m tall, forming dense clumps to several metres across. It has a dense crown of glossy, dark green to blue-green leaves, which often extends to the ground. The bark is grey-brown below, smooth, grey-brown to cream above and slightly rough and flaky at the base. The leaves are lanceolate, to 12 x 1.5 cm with numerous oil glands. There are 7 flowers in each unbranched, axillary inflorescence. The buds are club to pear-shaped, with a hemispherical to slightly conical cap. The fruits are globular, ca. 1 x 1 cm with a small opening and thick rim, the disc sunken with three or four valves which may protrude slightly. The seeds are brown and pyramidal. Occurs often in association with a mallee form of
may be confused also with E. lateritica and E. suberea, both of which have double conic buds with conical opercula and E. lateritica has cup-shaped fruits. E. suberea has falcate adult leaves and up to 20 buds per inflorescence. Flowering Period: July-January Distribution and Habitat in the Moora District Occurs between Eneabba and Badgingarra over a geographic range of ca. 30 km. The largest number of populations occurs in an area north of Warradarge Hill, extending north to a few kms south of Eneabba and south to the Coomallo area. When described in 1978 by Brooker and Blaxell, E. johnsoniana was known from only three populations along the Brand Highway. A total of ca. 27 populations are now known with about 300-350 plants. There has been difficulty in resolving the total number of populations found in the past owing to their scattered nature in relatively large areas of uncleared native heath. Grows as an emergent over dense low heath as small populations or as isolated plants on undulating sandplains, lateritic mesas and uplands. Grows in association with Eucalyptus todtiana, E. tetragona, E. impensa, E. macrocarpa, E. drummondii and E. pendens in grey or white sand over laterite. Associated heath species include
Dryandra armata, Lambertia multiflora, Hibbertia hypericoides, Hakea conchifolia, Allocasuarina humilis and Xanthorrhoea sp. An unpublished survey (Lievense 1981) reported that the species occurred in the Lesueur area, but a voucher specimen from the survey and Beard 7814, from Mt Lesueur, identified at that time as
