Trieenea elsiae Hilliard
LC Indigenous Endemic

Morphological description

Herb, possibly annual, stems well branched from the base, c. 80-200 mm long, erect or sprawling, woody at base and there up to 1.5 mm in diam., pubescent with patent glandular hairs up to 0.5-0.75 mm long, leafy. Leaves opposite, becoming alternate on the inflorescence branches, blade 5-17 x 3-10 mm, elliptic or ovate-elliptic, base cuneate, tapering into a flat petiolar part 2-6 mm long, roughly 1/2-1/3 length of blade, upper margins with 3-5 pairs of coarse teeth, both surfaces glandular-pilose, hairs up to 0.5-0.75 mm long. Flowers few to many in congested rounded heads becoming oblong in fruit, only the lowermost 1-3 flowers distant, each raceme terminating a nude peduncle up to c. 40 mm long, these solitary or in few-branched panicles. Bracts c. 5-8 x 1.5-3 mm, the lowermost leaf-like, smaller and narrower upwards, adnate to pedicel only, hairy as leaves. Pedicels up to 0.5-lmm long. Calyx obscurely bilabiate, tube 0.5-lmm long, anticous lobes 2.5-5 x 0.5-1 mm, anticous lip split 2.5-5 mm, whole calyx glandular-pubescent, hairs up to 0.5-0.75 mm long. Corolla tube 3-4.5 mm long, cylindric in lower half and there c. 0.75 mm in diam., rapidly broadening upwards, c. 1.5 mm across mouth, whole corolla glandular-pubescent outside, limb 2.75-4 mm across lateral lobes, posticous lobes 0.75-1 x 0.75-1 mm, anticous lobe 1-1.5 x 0.75-1 mm, all lobes subrotund, posticous lip bearded at base in all but the smallest (selfed?) flowers, white with an orange patch at base of posticous lip and running down back of tube. Stamens 4, posticous filaments decurrent well down tube, all anthers 0.3-0.5 mm long, shortly exserted. Stigma either exserted or curled round in tiny flowers. Capsules 2.5-4.5 x 2-3 mm Seeds c. 0.5 x 0.4 mm, irregularly wrinkled in longitudinal bands, pallid amber. From: Hilliard, OM. 1994. The Manuleae: a tribe of Scrophulariaceae.

Diagnostic description

Trieenea elsiae is allied to T. schlechteri with which it is at least partly sympatric; they differ in facies (racemes remaining crowded in fruit in T. elsiae, very lax in T. schlechteri) as well as in floral detail: lowermost bracts in T. elsiae more or less leaflike (c. 5-8 x 1.5-3 mm versus 2-5 x 0.3-0.8 mm), calyx mostly larger (anticous lobes 2.5-5 mm long versus 1.75-2.5 mm), and posticous lip bearded at the base in all but the smallest flowers (always glabrous in T. schlechteri).

Habitat

The plants grow in the shelter of big boulders and rock overhangs. From: Hilliard, OM. 1994. The Manuleae: a tribe of Scrophulariaceae. Edinburgh University Press, Edinburgh. [All rights reserved]
