Description:Adromischns filicaulis (A.fragilis) is a highly variable and very slow growing adromischus usually with shiny grey-green leaves and rust coloured spots and margins. Note: Two subspecies are recognized, the nominate form and subsp. marlothii (A. marlothii, A. tricolor), but much variation has been recorded for this species that it might seem unnatural to divide it into two subspecies. The main difference is the presence or absence of stiff stilt roots. Stems: Branchlets simple, stout, elongate, erect or decumbent, 7-12 mm across up to 35 cm long, rarely with stilt adventitious roots. Roots: Fibrous. Leaves: 2-8 cm long, 5-15 mm broad, oblanceolate, elliptic to oblong, or linear-elliptic and almost terete (cylindrical), often spindle-shaped, narrowed on both sides, often distinctly flattened above grey-green to greyish brown,with or without dark spots. Moreover seedlings often begin with flat leaves. After the plant ages, the leaves will become terete. Tip acute or obtuse; base abruptly wedge-shaped. Margin horny, slightly expanded. Inflorescences: The flowering spike is 200-350 mm tall. Buds terete. abruptly narrowed towards tip, spreading. Flowers 1-1.3 cm, yellowish green, corolla tube yellowish-green tinged pink, lobes broadly triangular, white or pale yellow, tinged from pink to deep red with mauve mucro, rough, without club-shaped hairs. Anthers protruding from corolla-tube.
