description
Description. Annual herb 4 - 35 cm high, usually with a well-developed tap root. Glandular hairs 0.1 - 0.3 mm long. Stem pale, green or reddish brown, much-branched near the base (rarely simple), with spreading or ascending branches, glandular-hairy. Leaves basally clustered and cauline, pale green; lamina oblanceolate or lanceolate, often narrowly so, 5 - 30 mm long including the petiole, 0.7 - 5 mm wide, acute to subacute, glandular-hairy abaxially and on the margins and sometimes on the adaxial surface towards the base. Flowers in racemes, sometimes in umbels or corymbs, 5 - 500 + per plant; bracts lanceolate to linear, 1.8 - 25 mm long, glandular-hairy like the leaves; pedicels 5 - 30 mm long, sparsely glandular-hairy. Hypanthium depressed globose or globose, 0.6 - 2 mm long, 0.6 - 2.5 mm wide, glandular-hairy. Calyx lobes equal or subequal (with the anterior pair scarcely longer than the rest), 1.2 - 2.5 mm long, acute, sparsely to moderately glandular-hairy. Corolla pink with a dark pink midvein and a white or yellow throat; lobes + / - evenly arranged, slightly recurved, obovate with an attenuate base, rounded or scarcely apiculate, glabrous or sparsely glandular-hairy on the abaxial surface along the midvein; anterior (lower) lobes slightly shorter and narrower than the posterior pair, 3 - 6.5 mm long, 1.9 - 3.2 mm wide; posterior (upper) lobes 3.5 - 7.5 mm long, 2 - 3.8 mm wide; tube white, 0.5 - 1.5 mm long, shorter than the calyx lobes, glabrous or with a few glandular hairs distally. Labellum ventral, 4 - 6.5 mm long including a 1 - 1.5 mm long claw; hood pink with purplish maroon markings, sparsely glandular-hairy abaxially, papillae absent; appendage at the cleft apex pink with a yellow or white base, 1.8 - 3.5 mm long, incised or emarginate, glabrous; basal appendages oblong-clavate, 0.8 - 1.2 mm long, revolute distally, white with a yellow, papillate tip. Column sheath white, glabrous, 0.5 - 0.7 mm high with a thickened rim on the posterior side and 3 pendulous appendages on the inner surface towards the throat. Column whitish tipped pale pink, free, slender, 2.5 - 3.8 mm long, glabrous; stigmatic lobes to 1.5 mm long, incurved, the lowermost developing while the column is hooded, the uppermost developing later. Capsule depressed globose to globose or ovoid, 1.5 - 3 mm long excluding calyx lobes. Seeds 0.5 - 0.8 mm long, 0.3 - 0.4 mm wide.
distribution
Distribution. Levenhookia chippendalei is widespread in the arid zone in Western Australia and the Northern Territory (Fig. 7 E), occurring from near Meekatharra to the Dulcie Range, north-east of Alice Springs.
etymology
