4); slightly protuberant before anterior margins of eyes, fastigio-facial angle rounded subobtuse
; frontal costa as seen in cephalic aspect relatively narrow, longitudinal sulcus deeply narrow, the sulcus width about two-third times the width of the antennae base.
Conidia solitary, thin and smooth walled, cylindric to cylindro-obclavate, 0-8 septate, obconic base, subobtuse

11 am to 19 pm, with a weak odor, strongly downwardly secund at anthesis (in lateral braches) to divergent (in the terminal branch), densely arranged, 42-43 mm long (not including the stamens); pedicels stout, 5-6 mm long, 7-8 mm in diameter at the apex, green, glabrous; sepals elliptic, apex obtuse and slightly emarginate, 27-28 x 13 mm, inconspicuously white-lepidote inside, glabrous outside, free, ecarinate, yellow, distinctly convex, thinly coriaceous toward the apex, thick at the base; petals narrowly elliptic, apex narrowly emarginate, 35 x 13-14 mm, yellow, erect to slightly suberect and forming a tubular corolla ca.10 mm in diameter at the apex, bearing at the base 2 suboblong to obovate, acute, subobtuse
to obtusely and irregularly bidentate, ca.
Inflorescence subcylindric, simple, umbellate, sunk in the center of the rosette, 50-55 mm long (excluding the petals), 22-27 mm in diameter, 11 to 16-flowered; floral bracts entire, subobtuse
and minutely apiculate, cucullate, white-hyaline except for the red apex, membranous, finely nerved, ecarinate, inconspicuously and sparsely white-lepidote inside, the outer ones subspathulate, 20-22 x 4-5 mm, equaling to slightly exceeding the ovary, the inner ones sublinear-lanceolate, acute, 15-17 x 2.5-3 mm, equaling the pedicels to slightly shorter than the ovary.
Flowers all perfect, sessile, 38-41 mm long (with extended petals), fragrant; sepals ovate-lanceolate, subobtuse
and distinctly apiculate, 7 x 2-2.5 mm, connate at base for 2-3 mm, entire, greenish, subdensely and coarsely white-lepidote, the posterior ones carinate with keel slightly decurrent on the ovary, the anterior one obtusely if at all carinate; petals broadly spatulate, 31-33 x 9 mm, connate at base for 2-4 mm in a common tube with the filaments and style, white, the free lobes broadly obovate, obtuse to slightly emarginate, suberect at anthesis, distinctly exceeding the stamens, bearing 2 longitudinal callosities ca.
9 x 7 mm, subcylindrical, green, glabrous; sepals slightly asymmetrical, subelliptic-obovate, apex subacute, 35-36 x 12-13 mm, glabrous, free, ecarinate, yellowish-green, thin in texture; petals sublinear, apex narrowly obtuse-cucullate, 81-82 x 7-8 mm, bright yellow, strongly recurved at anthesis, completely exposing the stamens, becoming pendent-flaccidescent afterwards, bearing at the base 2 linear, prevailingly acuminate, but sometimes subobtuse
or bidentate, entire, ca.
Inflorescence simple, densely cylindrical, erect, 11-14 x 2.8-3 cm, shorter than the leaves; floral bracts ovate, apex broadly acute to subobtuse
and minutely apiculate, erect, densely imbricate, entire or remotely denticulate at apex, undulate toward the base, completely hiding the calyx but slightly shorter than the corolla, 35-40 x 18-22 cm, ecarinate, pale rose and soon paleaceous, submembranaceous, densely white-lanate mainly near the base and along the basal margins.
