In its cephalic morphology Omegops tilabadensis shows similarity to the topotypes of Omegops accipitrinus accipitrinus as revised by Richter & Richter (1933), including the characteristic ornament of the postocular area of fixigena, which is smooth
adaxially and covered with eight large tubercles abaxially.
7g, 8b, g-i), or these sheaths extensions connect the vascular bundles abaxially to the epidermis and
adaxially to the hypodermis (Figs.
Pinnate leaves bearing leaflets,
adaxially inserted, departing from the rachis at an angle of 78[degrees]-80[degrees], regularly spaced 1.15 mm, straight or slightly falcate near the subacute apex; 13.05 to 13.64 mm in length and 2.8 mm in width.
In adult plants, stipes are nearly circular in section,
adaxially sulcate, with one deep groove, and abaxially rounded; below the epidermis there is a wide hypodermic zone of fibers, 8-10 layers thick and a leaf trace with 3 strands included in a massive parenchymatic central area (Fig.
The occipital furrow curves
adaxially forward to meet S1, giving a trapezoidal shape to LO.
Leaves 12 to 14 in number, suberect-recurved, forming a broadly crateriform rosette; sheaths broadly elliptic, 19-25 x 17-20 cm, subdensely pale-brown lepidote on both sides, greenish or sometimes reddish near the apex; blades linear, not narrowed toward the base, 30-44 x 11-14 cm, glabrescent abaxially, inconspicuously and sparsely white lepidote
adaxially, rose-red throughout, more so
adaxially or green toward the base and reddish near the apex, bearing dark green, sparsely arranged irregular spots, apex broadly acute to rounded and apiculate, apiculous ca.
1 mm, ovate to lanceolate, orange to reddish-brown, marginally ciliate, deciduous
adaxially, more dense in the margin; blade surface darker
adaxially; veins evident, free, 1-2-forked, ca.
Sepals abaxially densely tomentose and
adaxially glabrous, incurved in anthesis, the 4 lateral sepals abaxially biglandular, the anterior sepal eglandular.
The occipital furrow is distinctly indicated abaxially, directed inwards and backwards,
adaxially becoming shallower.
