Siphocampylus sulfureus

Siphocampylus sulfureus is a species of plant in the family Campanulaceae. It grows as an annual herbaceous shrub to 3 m (occasionally 4 m) tall. It has tubular yellow flowers arranged in whorls around the vertical stems. The flowers emit a pungent musky smell reminiscent of foxes, particularly at night. In the day, white-throated hummingbirds ("Leucochloris albicollis"), Brazilian rubies ("Clytolaema rubricauda") and purple-breasted plovercrests visit the flowers while at night the tailed tailless bat ("Anoura caudifer") visits.
