備註: COL, POWO 已合併. 大帽山耳草=粵港耳草 GBIF: Hedyotis bodinieri is syn of Hedyotis loganioides 大帽山耳草同粵港耳草根本分不出, 建議合併 (info from 柴娃娃植物網) Taxonomic notes on the genus Hedyotis sensu lato (Rubiaceae) in China: The type specimens of H. loganioides Bentham (1861: 149) [粵港耳草]and H. bodinieris Léveillé (1912: 64)[大帽山耳草] were both collected from Hong Kong. Léveillé (1912) didn’t compare with the sympatric conspecific species, H. loganioides, while describing his new species. The difference between the two species only limits to the density of pubescence at the young shoots and peduncles, according to the original description, that is, glabrous in H. loganioides and puberulent in H. bodinieris. Field observation on the different populations at all known localities showed that this feature varies a little with the changing of habitats. The young shoots are slight hairy when the habitats are opened and sunny but glabrous when shady and humid. All stems and shoots become glabrous with aging. The species grows uncommonly in the mountainous slope, near summit or under the forest, of the Pearl River Delta district of Guangdong province. TBC: 大帽山耳草同粵港耳草好相似, 不掛除是粵港耳草, 或根本大帽山耳草沒此品種 FOC(ENG) Herbs or subshrubs; stems pilosulous. Leaf blade drying membranous, margins not revolute when dry. Inflorescence shortly cymose. Flowers pedicellate. Calyx lobes sublinear, acute, as long as corolla tube. Corolla white; tube slightly longer than lobes. Anthers included. Fl. May. ● Mountaintops. Hong Kong (Damao Shan). This very poorly known species is not included in the key to species here. It may will turn out to be an older name for an otherwise-known species. --17a.小灌木,小枝及總花梗被微毛--大帽山耳草 --17b.多年生草本或基部多少木質,小枝及總花梗無毛 ---18a.托葉全緣;三歧聚傘花序具10-20花--粵港耳草 ---18b.托葉具腺齒或裂片; 二聚傘花序具數朵花--疏花耳草 2015.2.28 FoHK info Small shrubs, to 50 cm tall.
