stem 2–3 ft. high, simple or branching in the upper part, stout, 1 1/2–2 1/2 lin. thick at the basal part, pubescent with minute curved hairs; internodes numerous, 2/3–1 1/2 in. long; leaves ascending or spreading, those at the middle and lower part of the stem 1 1/2–2 in. long, 1/2– 3/4 in. broad, oblong, obtuse or subacute, truncate or truncately subhastate at the base, the upper and those on the branches much smaller and more hastate, minutely scabrous near the margins above and on the veins beneath, otherwise glabrous; petiole 1–3 lin. long; umbels 3–9 to a branch or stem, racemose, pedunculate, 3–15-flowered; peduncles 1/4–1 1/4 in. long, subtomentose; bracts 1 1/2–2 lin. long, subulate or filiform; pedicels 1/3– 1/2 in. long, subtomentose; sepals 1 1/2–1 3/4 lin. long, 3/4 lin. broad, lanceolate or oblong-lanceolate, acute, minutely pubescent; corolla-lobes ascending, 2 1/2–3 lin. long, 1 1/2–2 lin. broad, oblong, very obtusely rounded at the apex, slightly concave, glabrous on both sides, sometimes minutely ciliate at the base, greenish or yellowish-green; corona-lobes much shorter than the staminal column, 1/2– 2/3 lin. long, 1/3– 1/2 lin. broad, ovate-oblong or oblong, obtusely rounded at the apex, with an appendage and 2 distant parallel keels placed near the margins and having a short keel on each side extending from the base of the appendage obliquely downwards and out to the margins on the inner face, so that viewed sideways the margins appear to make a fold at this point; appendage 2/3 lin. long, arising just below the apex of the lobe and usually more than half as broad as it is at the base, linear, deeply bifid or trifid or divided to the base into 2–3 contiguous subulate segments, erect, reaching to or slightly overtopping the style-apex, slightly recurved-hooked at the apex; staminal column 3/4–1 lin. long; anther-appendages subreniform, very obtuse, erect beneath the rim of the broad flat or slightly concave style-apex; caudicles attached to the side of the oblong pollen-masses between the middle and apex. null
