Description:Latin Diagnosis - Suffrutices caulibus viscidis; laminis foliorum ovato-cordatis pilis adpressis simplicibus atque aliquot glandulosis; bracteis involucellorum 7-10 lineari-lanceolatis, quam calyce parum longioribus; calycibus valde ciliatis; corollis albis (erubescentibus) 12 mm longis interne glabris (unguibus includentibus); columna staminalis et stylis et stigmatibus glabris inclusis; fructibus oblatis minute pubescentibus.
Species Description - Subshrubs 1.5 m tall, well branched, the stems viscid, the glandular hairs 0.5 mm long. Leaf blades ovate, cordate, serrate, acuminate, mostly 3-6 x 1.5-4.5 cm, palmately 5-7-nerved, discolorous, with appressed, predominantly simple hairs (0.3-0.4 mm long) on both surfaces, with glandular hairs at least on margin; petioles 1-3.5 cm long, densely glandular-pubescent; stipules subulate, 2 mm long, pubescent. Flowers solitary in the leaf axils, the pedicels 2.5-5.5 cm long, slender, glandular-pubescent; involucellar bracts 7-10, linear-lanceolate, 8-10 x 1 mm, glandular pubescent and with basal cilia 1-2 mm long; calyx 7-9 mm long, prominently ciliate on margins and nerves (hairs 1.5 mm); corolla 12 mm long, white (fading pink), externally pubescent, internally glabrous (including margins of claws); staminal column 6-8 mm long, glabrous, pallid, the filaments 1-1.5 mm long; styles emergent from the staminal column, glabrous; stigmas capitate, glabrous. Fruits oblate, 7 mm diam., minutely pubescent; mericarps dehiscent, 4 mm high; seeds 3 mm long, glabrous, striate.
Discussion:The specific epithet, from the Latin (spurius, false), refers to the close similarity to Pavonia purpusii and the easy confusion with the latter species, as well as with the similar P. fonsecana. However, P. spuria is distinguished from those two species by having claws of the petals that are entirely glabrous.
