description
Campsidium valdivianum is a liana , the branches of which reach a diameter of 2.5 cm. The branches have an irregular, almost square cross-section and are not hairy apart from a few fine scales. The leaves are opposite and are divided into five to 17 pinnate-shaped leaves. These are seated, with entire margins or slightly jagged towards the tip, elliptical in shape, rounded at the tip or somewhat pointed and rounded at the base or obliquely wedge-shaped. They are membranous, reach a length of 0.8 to 3.7 cm, a width of 0.5 to 1.5 cm and are covered with scattered red scales on both sides. The main axis of the leaf is edged to narrow wings between the partial leaves. The petiole is 1 to 3 cm long and only inconspicuously covered with scales.
The inflorescences are made of a few flowers composite grapes that are terminally and are hairless or only slightly fine scales. The calyx is bell-shaped, 6 to 12 mm long and 7 to 9 mm wide and evenly covered with five approximately 2 to 3 mm long, triangular and somewhat pointed teeth. The crown is tubular, red in color and slightly narrowed at the tip. It is 3 to 3.5 cm long, the crown throat has a diameter of 0.5 to 0.8 cm, the corolla tube is 2.5 to 3 cm long and covered with 0.3 to 0.5 cm long corolla lobes. The corolla tube is only hairy at the attachment points of the four stamens , the corolla lobes are ciliate and hairy on the inside with short, pearl-like trichomes . The anthers protrude only slightly over the crown, they consist of two parallel, not forked counters that are partially fused with the tip of the stamen. They are 4 to 5 mm long; the connecting fabric between the counters (connective) is slightly enlarged. The stamp is 3 to 3.5 cm long. The ovary is ovate, 3 mm long, 1.5 mm wide and some drüsig- papillous but otherwise hairless. The ovules are in several rows in the ovary chambers. The flower base is very thin, cup-shaped, 1 mm long and 1.5 mm wide.
The fruit is a narrow elliptical capsule 5.5 to 8.5 mm in length and 2.3 to 3 cm in diameter. It stands on a permanent calyx, is petiolate, blunt or slightly pointed at the tip. Their surface is slightly covered with inconspicuous, fine scales. The seeds are thin, elliptical, 7 to 10 mm long and 12 to 15 mm wide. The small body of the seed is clearly set off from a brownish-veined and translucent wing surrounding it.
distribution
The species occurs in the region around Valdivia in Chile and southern Argentina and grows at altitudes between 0 and 800 m.
