Distribution
Endemic to the Rio Grande valley system in central Bolivia and the adjacent upper Pilcomayo/Cachimayo valley. Almost all collections come from the Chuquisaca Departamento within a 30 km radius of Sucre, Tarabuco and Zudafiez - i.e. south of the Rio Grande - two collections have been made north of the river, from near Pasorapa and Aiquile.
Ecology
Philibertia velutina occurs in dry, frequently degraded bushland on steep slopes at altitudes of c. 2100 - 2600 m.
Morphology General Habit
Perennial herb with stems twining to c. 2 m from a woody base; latex white
Morphology General Indumentum
Whole plant pubescent to densely tomentose
Morphology Leaves
Leaves with petiole 0.4 - 3 cm long, tomentose; lamina 4 - 7(- 9) x 0.7 - 2(- 3.5) cm, lanceolate, narrowly oblong or elliptic with an acute or shortly apiculate apex and a cordate base, pubescent to tomentose adaxially, grey- or white-lanate abaxially
Morphology Reproductive morphology Flowers
Flower buds ovoid, with minute projections from corolla lobe sinuses
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther wings convex in outline, broadest in the middle and running the entire length of the staminal column
Morphology Reproductive morphology Flowers Calyx
Calyx lobes c. 4- 5 mm long, linear, tomentose
Morphology Reproductive morphology Flowers Corolla
Corolla deeply campanulate, united into a tube for 3/4 of its length, tomentose outside, glabrous within; tube 5 - 7 mm long, subcylindrical, greenish yellow, sometimes tinged with dull red; lobes 1 - 2 mm long, broadly triangular and somewhat recurved at the tip, greenish yellow
Morphology Reproductive morphology Flowers Corona
Staminal corona lobes absent
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma head flat, ± level with top of anthers; paired stigma head appendages absent
Morphology Reproductive morphology Flowers Gynostegium
Gynostegium 2.5 - 3 mm long, seated on a weakly pentagonal basal coronal ring
Morphology Reproductive morphology Flowers Pollinarium
Corpusculum c. 0.2 mm long, ± rhomboid; translator arms c. 0.3 mm long, terete proximally but geniculate and flattened distally; pollinia c. 1 x 0.3 mm, flattened, obovate-oblong
Morphology Reproductive morphology Fruits
Follicles solitary, 4.5 - 5 x 1 cm, lanceolate in outline tapering gradually into a broadly truncate apex, weakly ridged longitudinally, and covered entirely in tomentose indumentum
Morphology Reproductive morphology Inflorescences
Inflorescences extra-axillary, umbelliform initially but lengthening to reveal staggered and apparently spirally distributed scars, 2 - 10 nodding flowers present at any one time; peduncle ± as long as petiole of adjacent leaf, tomentose; bracts c. 4 mm long, filiform, tomentose; pedicels c. 4- 10 mm long, tomentose
Morphology Reproductive morphology Seeds
Seeds c. 4- 5 x 2.5 mm, angular, irregularly verrucose; coma of silky hairs c. 2.5 cm long.
Note
This species can be readily recognised by its small greenish yellow tubular flowers with a well- defined basal corona ring, and no staminal corona lobes. The gynostegium is unique with its characteristic convex margin to the anther wings, which run the entire length of the column. Philibertia velutina is probably most closely allied to P. peduncularis and P. stipitata.
Type
