Kalanchoe integra

A perennial succulent herb 0·3-2 m. high. Stem erect or ascending, fleshy, terete, up to 2 cm. in diameter at the base, usually simple, sometimes branched, glabrous or glabrescent towards the base, more or less pubescent-glandular above (hairs of the indumentum short, usually not longer than 0·5 mm., hyaline or pale tawny, spreading, thin, capitate-glandular) or also glabrous. Leaves decussate, horizontal to deflexed, petiolate, not very crowded below; lamina 4·3-25(30) x 1·5-12(20) cm., ovate or oblong-ovate to spathulate, usually with the breadth subequalling or less than half the length, the median passing gradually (in shape & size) into the bract-like upper ones, rounded at the top, irregularly doubly crenate to sometimes sublobed at the margin, sometimes edged with red, cuneate at the base and decurrent along the petiole, all glabrous or sometimes the upper ones sparsely pubescent-glandular, fleshy (but less thick than the majority of other species), flattish, concave, pale green changing to dark green or brownish on drying and then rather thin to membranous; petiole up to 4 cm. long, flattened and grooved above, broadened and ± embracing the stem at the base but not or slightly connate with the opposite one. Flowers in many-flowered cymes, grouped in corymbs forming terminal, usually large (up to 40 cm. or more long) panicles, sometimes only the terminal corymb present; branches of the panicle at ± 45° with the axis, ± pubescent-glandular or glabrous, the lower ones up to 35 cm. long, floriferous only in the terminal 1/4-1/3; pedicels 2-7(10) mm. long, glabrous or ± glandular-pubescent; bracts linear, very attenuate and acute to nearly filiform. Calyx 2·4-10 mm. long; tube 0·1-1(1·5) mm. long; sepals 1-1·5 mm. broad at the base, lanceolate to linear-lanceolate, ± attenuate, very acute, rather scattered between them, green, sometimes lineolate with red, pubescent-glandular to glabrous, thin on drying. Corolla 11·5-22 mm. long; corolla-tube papery and somewhat rigid in fruit, white below, coloured ± like the lobes upwards, glandular-pubescent or glabrous; corolla-lobes 4·5-7·5 x (2·5)3·5-5 mm., oblong-lanceolate to elliptic, acute or subacute and with a somewhat long apiculum (up to 1 mm. long) at apex, sulphur-yellow to bright or deep yellow, or bright salmon to red, deep red, orange or brick. Anthers 0·5-0·7(1) mm. long, all included or the upper ones ± exserted. Follicles 6-8·5 mm., fusiform, attenuate; styles 0·75-2(2·5) mm. long. Scales 2·5-3·5 mm. long, linear. Seeds c. 0·75 mm. long, oblong, ribbed.
