Description:Latin Diagnosis - Frútices caulibus dense stellato-pubescentibus; laminis foliorum late ovatis plus minusve obtusis insigniter discolorous; floribus solitariis in axillis foliorum; bracteis involu-cellorum ca. 12 copiose setosis (pilis 4-5 mm longis) 16-18 mm longis; calycibus profunde parritis, lobis 3-costatis; corollis rubris 4 cm longis; fructibus ignotis.

Species Description - Shrubs 1 m tall, the stems with setae 5 mm long on lower stem and otherwise densely stellate-pubescent, the hairs <1 mm diam., the arms arching and overlapping. Leaf blades broadly ovate, 4-5 x 4-5 cm, deeply cordate, obscurely undulate-crenate to subentire, obtuse or subacute, notably discolorous, palmately 7-nerved, stellate-pubescent above and beneath (the indumentum beneath similar to that of stem, but sparser above); petioles often equaling or exceeding the blade, densely stellate-pubescent; stipules subulate, ca. 3 mm long. Flowers solitary in the leaf axils, the pedicels ca. 3 cm long, stellate-pubescent like stem and in distal portion densely setose with ferruginous setae 4-5 mm long; involucellar bracts ca. 12 (?), linear-lanceolate, 16-18 x 1 mm, copiously setose with ferruginous setae 4-5 mm long (radiating outward), with underlying stellate-pubescence; calyx 12-13 mm long, deeply divided, the lobes 3-ribbed, 10 mm long, 4 mm wide, densely stellate-pubescent; petals 4 cm long, red, minutely and obscurely stellate-pubescent externally; genitalia not seen. Fruits unknown.

Discussion:Pavonia longitricha is distinctive for the remarkable long setae on the involucel. Its more or less obtuse leaves are also notable.
