description
Juanulloa mexicana is a semi- epiphytic growing shrub or a vine whose branches take on a green-sand paint dry and irregularly striped and shingled. The leaves are elliptical or elongated, up to 20 cm long, the widest point is above the center. The leaves are leathery and smooth, but covered with sea urchin-like or tree-shaped trichomes , which are isolated on the leaf veins and the leaf surfaces of the surface and densely on the entire lower surface. The petioles are channel-shaped on the upper side, hairless to densely hairy.
The inflorescences are contracted, almost umbellate to umbelliferous panicles that stand at the ends of the branches. The petioles are finely tomentose and about 8 to 12 mm long. The flowers have a 12 to 15 mm wide calyx , which is dense yellowish, orange or brownish hairy on the outside. It is divided up to about half into five egg-shaped to elongated lobes that have a pointed tip and are covered with some hair on the inside. The crown is about 3.5 to 4 cm long and thus about three times as long as the calyx. It is tubular, conspicuously five-ribbed or folded and somewhat expanded in the upper area. The outside is covered with fine felted yellowish, star-shaped trichomes, the inside is hairless except for an area around the starting point of the stamens. The corolla lobes are egg-shaped, about 5 mm long.
The slender stamens are fixed about 5 to 8 mm above the crown base and are hairless except for a dense tuft of hair at the base. The anthers partly protrude slightly over the crown, are 10 mm long and 1.5 mm wide, at the base they are spear-shaped, on the opposite side there is a short point. They open longitudinally, the connective tissue between the theca is marked by a narrow purple line. The stylus is slender and flattened the small scar is elliptical and is located on the height of the peaks of the dust bag.
The fruit is a soft, conical or egg-shaped berry with a length of about 2 cm. It is not completely enclosed by the adjoining calyx tips, at the tip is an elongated, non-sloping stylus. The kidney-shaped seeds are 4 to 5 mm long.
Occurrence
The distribution area of the species extends from Mexico to Colombia , many of the specimens collected were in very sunny locations.
