Plant 6-10 in. high, branched at the base; branches ascending, more or less curved or decumbent at the base, unifariously pubescent; leaves ascending or somewhat spreading, 1 1/2-2 1/2 in. long, 1/2-1 1/3 lin. broad, linear, acute, narrowed or rounded into a short petiole at the base, glabrous or sometimes shortly and sparsely subhispid on the midrib beneath; umbel terminal, solitary, 4-6-flowered; peduncle 2-10 lin. long, unifariously puberulous; bracts about 2 lin. long, subulate; pedicels 3-8 lin. long, unifariously puberulous; sepals 2-2 1/2 lin. long, linear-lanceolate, very acute, subhispid on the back, ciliate at the base; corolla-lobes spreading or ascending, 4-5 lin. long, 1 1/2-2 1/2 lin. broad, oblong-lanceolate or broadly ovate-lanceolate, subacute, reflexed along the margins, glabrous on the back, minutely papillate-puberulous on the inner face; corona-lobes arising at the base of and equalling the staminal column, 1 1/2-2 lin. long, erect, distant, alternating with a short flat broadly rounded lobule at their base, cucullate, oblong in outline, tapering into the column at the base, scarcely broader at the oblique apex than elsewhere, 2/3-1 lin. broad, viewed sideways, with the top margins slightly ascending to the dorsal apex, not produced into teeth at inner apical angles, which are much infolded forming a somewhat boat-shaped concavity on the inner face and when dorsally flattened in drying boat-shaped in outline, without oblique keels or wings on the sides, but with a transverse shelf-like flap or fold within a little below the apex; staminal column about 1 3/4 lin. long; anther appendages rather large, elliptic-ovate or transverse, with their obtuse tips inflexed over the margin of the style-apex, which is variable in size and concavity; anther-wings rather long and broadly rounded.
