Hedyotis is a very problematic genus or group of genera. Neither the overall identity and limits of this lineage, nor the evolutionary patterns within it, are at all understood or delineated. Widely differing treatments have long been used in different regions and floras. The situation is far from resolution or even general consensus, and so many authors treat the genus very broadly[
]. In line with several recent (up to 2013) molecular and phylogenic studies, the Kew â€˜World Checklist of Selected Plant Familiesâ€™ has recognised a number of distinct genera and this is the treatment we are adopting here[
To complicate matters further, various authors have treated this species either as a synonym of Exallage costata (Roxb.) Bremek. (native from the Himalayas to west Malesia), or as a synonym of Hedyotis prostrata Blume (native from Indo-China to west Malesia)[
Exallage philippensis (Willd. ex Spreng.) Bremek.
Spermacoce philippensis Willd. ex Spreng.
Hedyotis philippensis is an open-branched, spreading, perennial plant with erect ot even clambering stems that bcome more or less woody. It can grow up to 120cm tall[
The plant is harvested from the wild for local use as a medicine.
E. Asia - southern China, Philippines.
Open forest areas, along streams and seasonally boggy localities, usually on sandy soils; at low to medium elevations[
The plant is found in the wild on sandy soils[
The roots are stomachic. A decoction is used in the treatment of dysentery, colic and stomach aches[
A decoction of the root is used externally as a wash for listless children[
]. The root is used as a poultice, specifically on scalds, and generally on any painful part of the body[
The aerial parts of the plant are eaten with a bitter gourd (Momordica sp.) after childbirth[
