Cuscuta japonica, an
annual satellite vine occurring in sunny locations in fields and
mountains, is parasitic on various plants; extending long vines, it
twines around host plants, emerges parasitic roots, and absorbs
nutrients from them. The vines are wire-like and tinged yellow or
purple-brown. Leaves measure less than 2mm long and are squamous.
Short inflorescences set many small white flowers; corollas measure
4mm long and cleft in five. Bloom time: August-October. |
