LEAVES numerous, standing upright on their footstalks, about a foot in length, and four inches in breadth, ovato-oblong, coriaceous, somewhat fleshy, rigid, smooth, concave, entire on the edges, except on one side towards the base, where they are more or less curled, on the upper side of a deep green colour, on the under side covered with a fine glaucous meal, midrib hollow above and yellowish, veins unbranched, prominent on the inside, and impressed on the outside of the leaf, young leaves rolled up.
LEAF-STALKS about thrice the length of the leaves, upright, somewhat flattened, at bottom furnished with a sheath, and received into each other, all radical.
SCAPUS or flowering stem unbranched, somewhat taller than the leaves, proceeding from the sheath of one of them, upright, round, not perfectly straight, nearly of an equal thickness throughout, of a glaucous hue, covered with four or five sheaths which closely embrace it. Two or more flowering stems spring from the same root, according to the age of the plant.
SPATHA terminal, about six inches in length, of a glaucous hue, with a fine bright purple at its base, running out to a long point, opening above from the base to within about an inch of the apex, where the edges roll over to one side, forming an angle of about forty-five degrees, and containing about six flowers.
FLOWERS of a bright orange colour, becoming upright, when perfectly detached from the spatha, which each flower is a considerable time in accomplishing. In the plant at Chelsea, the two back petals, or, more properly segments of the first flower, sprang forth with the nectary, and while the former became immediately vertical, the latter formed nearly the same angle as the spatha; four days afterwards the remaining segment of the first flower, with the two segments and nectary of the second came forth, and in the same manner at similar intervals all the flowers, which were six in number, continued to make their appearance.
COROLLA deeply divided into three segments, which are ovato-lanceolate, slightly keeled, and somewhat concave, at the base white, fleshy, and covered with a glutinous substance flowing in great quantities from the nectary.
NECTARY of a fine azure blue and most singular form, composed of two petals, the upper petal very short and broad, with a whitish mucro or point, the sides of which lap over the base of the other petal; inferior petal about two inches and a half in length, the lower half somewhat triangular, grooved on the two lowermost sides, and keeled at bottom, the keel running straight to its extremity, the upper half gradually dilating towards the base, runs out into two lobes more or less obtuse, which give it an arrow-shaped form, bifid at the apex, hollow, and containing the antheræ, the edges of the duplicature crisped and forming a kind of frill from the top to the bottom.
STAMINA five Filaments arising from the base of the nectary, short and distinct; Antheræ long and linear, attached to and cohering by their tips to the apex of the nectary.
STYLE filiform, white, length of the nectary.
STIGMA three quarters of an inch long, attached to, and hitched on as it were to the tip of the nectary, roundish, white, awl-shaped, very viscid, becoming as the flower decays of a deep purple brown colour, and usually splitting into three pieces, continuing attached to the nectary till the nectary decays.
