Conservation
Conservation status. CR B1ab(iii). Using criterion B1 of the IUCN (2001) Red List categories and criteria, Philibertia zongoensis should be regarded as Critically Endangered as it is known from a single location, with an assumed extent of occurrence less than 100 km2, and some habitat disturbance — the label data refers to remnants of cloud forest.
Distribution
Only known from the type collected in the Zongo valley N of La Paz.

Inflorescences extra-axillary with c. 30 flowers in a sub-umbelliform cluster; peduncle 8 cm long, tomentose with golden hairs; bracts deciduous; pedicels 4.5 – 5 cm long, red, minutely tomentose
Note
Philibertia zongoensis is a very striking plant with its large clusters of red flowers. Leaf, corona and pollinarium morphology are typical of Philibertia but the shape of the flower is more reminiscent of Funastrum. The corolla is much more deeply lobed than in other species of Philibertia and, as a result, the flowers are ± rotate rather than campanulate. However, the annular corona which surrounds the base of the gynostegium in Funastrum is not present in the new species and the leaf shape is quite different. The glabrous outer face of the corolla is unique in Philibertia, but occurs in some species of Funastrum, such as F. gracile Schltr. Recent molecular surveys (Liede-Schumann et al. 2005; Rapini et al. 2006) have placed Funastrum sister to the core Oxypetalinae clade (containing Oxypetalum and Philibertia together with a few smaller genera). It would be interesting to include P. zongoensis in future analyses of this group.
