ABSTRACT
A new hemiparasitic species, Striga crispata sp. nov., is described and illustrated from Tawu Township, Taitung County, Southern Taiwan. It most closely resembles the Australian species, S. parviflora (R. Brown) Benth, but can be differentiated by longer corollas that are pink or pinkish purple in color, corolla-lobes with crispate margins, and ornamented seed surface that is only covered by the primary ridge. A morphological description, line drawings, photographs, and conservation status are provided to aid identification.
KEY WORDS: Hemiparasite, Orobanchaceae, Striga, Striga parviflora, Taiwan.

Ecology: Striga crispata sp. nov. is only known from the type locality in Taiwan, found on the edge of streams, at altitudes 20–30 m. The host plant is Heteropogon contortus (L.) P. Beauv. ex Roem. & Schult (Poaceae) (Fig. 2), and the other congeners Striga asiatica (L.) Kuntze (Orobanchaceae) are found near this new taxon. The flowering and fruiting occurs from October to November, with it withering in winter.
