Hypericum phellos
Hypericum phellos is a species of shrub or small tree in "Hypericum" sect. "Brathys". The species is found in Colombia and Venezuela on scrubby slopes and moist woods. Description. "Hypericum phellos" grows tall, with strict and nearly always lateral branches. The yellowish brown, four-lined stems are ancipitous when young and become terete. The internodes are long. The sessile leaves spread from their base or are imbricate. The lamina is long and wide. The leaves are flat or recurved, never concave, and are thinly to thickly coriaceous. The apex of the leaf is acuminate to rounded and the  base is cuneate to angusate. Leaves have three to seven diverging basal veins and obscure tertiary reticulation. The one to five flowered inflorescence is terminal, arising on short lateral shoots. The peduncles and pedicels are long. The star-shaped flowers are wide. The sepals are long and wide, each with five to seven distally branched veins. The bright yellow to occasionally orange-yellow petals are long and wide, about twice as large as the sepals. The forty to two-hundred stamens are, at the most, long. The ovoid ovary is long and wide. The three styles are long. The stigmas  are small or subcapitate. The globose capsules are long and wide. The seeds are about long. "H. phellos" is easily distinguished from close relatives by its corky ridges on its internodes and by its deciduous leaves. When leaves are persistent, they are either marcescent with an acute apex (var. "marcescens"), or broad and appressed, lacking corky emergences (subsp. "platyphyllum"). The other subspecies, "oroqueanum", has appressed leaves that are not persistent. Habitat and distribution. "Hypericum phellos" grows on scrubby slopes and in moist woodlands. It prefers altitudes between . The shrub occurs in Santander, Norte de Santander, and Cesar in Colombia and  in Táchira in Venezuela.
