AB -<i>Palmatiboea curvituba</i> and <i>P. recurva</i> are described and illustrated here. Both species resemble <i>P. heucherifolia</i> in having the calyx divided to the base, palmately veined leave blades with eglandular hairs on both surfaces, and a pink, externally puberulent corolla. However, <i>P. curvituba</i> differs from <i>P. heucherifolia</i> in that its corolla tube curved-funnelform-tubular (vs. funnelform-tubular), ratio of the corolla tube length to the orifice diameter ca. 2.62–2.92 (vs. ca. 1.4–1.74); leaf blade abaxially glabrous between veins (vs. pubescent); calyx lobes margins entire (vs. denticulate). P. recurva differs from <i>P. heucherifolia</i> by: corolla tube with a distinct pit on the middle of adaxial lip (vs. without a pit), ratio of the corolla tube length to the orifice diameter ca. 2.82–3.17 (vs. ca. 1.41—1.74), upper half part of corolla tube slightly upward-curving (vs. not upward-curving); peduncle, abaxial surface of bracts and abaxial surface of calyxes villous and mixed glandular-pubescent (vs. villous mixed eglandular-pubescent). Based on the IUCN Red List Categories and Criteria, the conservation status of both new species is assessed as Data Deficient (DD).
