The leaves are variously lobed and entire, Fruits are oblong-ovate
or elliptic, about 5 mm long, with two seeds per pods, seeds are reddish brown, oblong and wingless, .
Basal leaves pinnatifid with (2 or)3-8 lateral lobes on each side; middle cauline leaves serrate or laciniate; fruits narrowly oblong-ovate
to oblong, 2-2.3 mm wide L.
Plant terrestrial or saxicolous, forming sparse groups hanging in a perpendicular-ascending angle in very steep to nearly vertical shaded slopes, long caulescent and propagating by short aggregated shoots sparsely distributed along the naked portion of the stem, flowering 140-250 cm tall, including the naked portion of the 60-180 x 1-1.5 cm stem solely covered by disintegrated old fragments of the leaf sheaths; Leaves fasciculate, persistent and concentrated in the distal portion of the stem, apparently monomorphic except for the shortly triangular, spinose, paleaceous reduced leaves of the renovation shoots; sheaths narrowly oblong-ovate
Species of Didymaea are characterized by their procumbent or climbing stems, opposite leaves with ovate, oblong-ovate
, lanceolate, elliptic, or rarely linear blades, small, shallowly to deeply bilobed or geminate interpetiolar stipules, axillary inflorescences with small, bisexual homostylous flowers with calyces reduced or absent, small, white to purple corollas with short tubes and 4-valvate lobes, 4 stamens with dorsifixed anthers, 2-locular ovaries with one axillary ovule per locule, and black, drupaceous fruits that are dimidiate and deeply bisulcate or sometimes subglobose.
Rhizomes short, covered with brown scales; fronds 25-50 cm long; blades pinnate, 15-40 cm long, oblong-ovate
; pinnae 4-10 pairs, alternate; sori round, scattered; indusia peltate.
Stem leaves [+ or -] concave, either straight, oblong-ovate
with abruptly acute or obtuse and apiculate or rounded apex, or falcate, ovate to oblong-ovate
with gradually and shortly to longly acuminate apex; erect-spreading to imbricate, usually complanate; margin plane, entire or slightly denticulate near apex; costa short and double, occasionally absent; median lamina cells linear-flexuose, becoming shorter and wider towards apex and slightly shorter, wider and porose towards base; marginal cells similar or slightly shorter and wider than adjacent median lamina cells; alar cells numerous, hyaline, inflated, forming a well delimited group, slightly or longly decurrent.
LEAF DESCRIPTION: SIMPLE, 2" to 3" long and half as wide, ovate to oblong-ovate
shape with coarsely serrated margins.
Growing up I never thought of it by name nor thought of it at all till it began to die, though even that took time, slow meditating time, in which the seasons failed, as always, to arrive except in fragments, moments, snow piled up on rain, summer like a drill, each oblong-ovate
Stem leaves differentiated in size on the same stem, generally larger in the lower parts and smaller in the upper parts of the stems, 1.0-1.5 x 0.4-0.7 mm, oblong-ovate
to oblong-isosceles-triangular, upper margins involute to a nearly cucullate apex; borders narrow above, clearly widened below; hyaline cells broad-rhomboidal in the upper parts of leaves, mostly divided, narrow-rhomboidal below, less divided, with large pores on both surfaces.
Flowers 28-30 mm long, sessile, densely and polystichously arranged, suberect, odor not detected; sepals oblong-ovate
, strongly asymmetric with a subrounded wing distinctly exceeding the midnerve, ca.
