Plants bear more or less clustered unifoliate pseudobulbs ( rarely bifoliate ), coriaceous dark-olive leaves, and possess long inflorescences with successive flowering.
22.
"D . falcata " bears grey barks, thick coriaceous leaves variable in shape with stout flowers ( Wealth of India . 2002 ).
23.
The plant has long leaves, with a tough ( coriaceous ) consistency because of the aridity in the canopy of trees, due to a short dry season.
24.
Leaves 4-whorled, simple, irregularly serrulate, glaucous, coriaceous, sessile, with a broad asymmetrical base, 8-30 x 2-8 mm.
25.
Very early Blattopterans had a large, discoid pronotum and coriaceous forewings with a distinct CuP vein ( a unbranched wing vein, lying near the claval fold and reaching the wing posterior margin ).
26.
The lamina are 16 30 mm long and 4 6 mm wide, narrowly oblong to narrowly elliptic, plane, not cucullate or carinate, concolorous, not or slightly glaucous and chartaceous to thinly coriaceous.
27.
The mature tree is 15-25 m in height, with a 0.5 m pinnately compound leaves bear three to five opposite to sub-opposite pairs of coriaceous leaflets, glabrous above and covered with minute scales below.
28.
Its leaves are odd-pinnate, coriaceous, 15-50 cm long, comprising 9-17 leaflets, each of which is 3-15 cm long by 1-5 cm wide, and ovate to elliptic-lanceolate in shape.
29.
Like other orchid species in " Eulophia " and " Oeceoclades " that are adapted to arid climates, " O . beravensis " has narrow and coriaceous ( leathery and stiff, but flexible ) leaves with minute serrations.
30.
Apex is acute to acuminate with blunt tip, base is acute to attenuate, coriaceous, glabrous; midrib of the leaf is canaliculate above, stout beneath; secondary nerves usually 5-9 pairs, where lower pairs closer than above ones; tertiary nerves are strongly reticulate on both surfaces.
