Conservation
Conservation status. Data Deficient. Although known from a single population with an assumed extent of occurrence less than 100 km2 (using criterion B1 of the IUCN (2001) Red List categories and criteria), there is no evidence to suggest the habitat is under threat or that the population is in decline.
Distribution
Only known from the type collected near Villa Serrano in central Bolivia.

Steep mountain slopes with remnants of moist forest and areas of open pasture. Growing in open areas amongst shrubs. Alt. c. 2200 m.

Morphology Leaves
Leaves with petiole 1 – 2 cm long; lamina 3 – 5.5 × 1 – 2.7 cm, ovate, with an attenuate apex and a deeply cordate base
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther wings 1.2 mm long, very slightly triangular, the margins only weakly flared from the column
Morphology Reproductive morphology Flowers Calyx
Calyx lobes 2 – 3 mm long, filiform, pubescent with spreading white hairs
Morphology Reproductive morphology Flowers Corolla
Corolla globose and with lobes ± valvate in bud, pure white, minutely pubescent outside, glabrous within; tube campanulate, 2 – 2.5 mm long; lobes 2.5 – 3 × 1.5 – 2 mm, broadly triangular, margins slightly reflexed
Morphology Reproductive morphology Flowers Corona
Basal coronal ring weakly developed, forming a green, slightly fleshy collar around the base of the gynostegium Staminal corona lobes absent

Stylar head appendages vestigial, paired, extending only shortly beyond anthers, white
Morphology Reproductive morphology Flowers Gynostegium
Gynostegium ± sessile
Morphology Reproductive morphology Flowers Pollinarium
Corpusculum c. 0.2 mm long, broadly ovoid, brown; translator arms c. 0.1 mm long, somewhat flattened; pollinia c. 0.25 mm long, ovoid, not strongly flattened
Morphology Reproductive morphology Fruits
Follicles and seeds not seen
Morphology Reproductive morphology Inflorescences
Inflorescences extra-axillary, with flowers distributed irregularly along the axis; peduncle (to first flower) 1 – 1.5 cm long; bracts 1 – 2 mm long, filiform; pedicels 6 – 10 mm long
Note
This species is similar to Philibertia picta Schltr., but differs in its more broadly ovate rather than triangular leaves, its more deeply divided corolla, the subsessile rather than stipitate gynostegium, the reduced size of the corona around its base, and the absence of staminal corona lobes. The anther wings are also slightly longer than in P. picta.
