精神病亚属精神病（茜草科）在墨西哥和中美洲有61种8变种的下层灌木和小树。该亚属的多样性在巴拿马（40种）和哥斯达黎加（32种）最为丰富，其次是墨西哥南部（26种）和危地马拉（26种）。巴拿马的地方性也最大（15种）。哥斯达黎加和巴拿马的物种丰富地区尤其值得保护。61种可分为8个类群；几个类群和种复合体包含一个范围广泛的种和几个范围小得多的种。只有一个物种丰富的组，P. calophylla组，缺乏一个连续广泛的成员。
Psychotria subgenus Psychotria (Rubiaceae) comprises 61 species and eight varieties of understory shrubs and small trees in Mexico and Central America. The subgenus is most diverse in Panama (40 species) and Costa Rica (32 species), with a secondary center of diversity in southern Mexico (26 species) and Guatemala (26 species). Endemism is also greatest in Panama (15 species). Species-rich regions in Costa Rica and Panama are especially recommended for conservation efforts. The 61 species are grouped into eight species-groups; several group and species complexes contain one wide-ranging species and several species with much smaller ranges. Only one species-rich group, the P. calophylla group, lacks a continuously wide-ranging member.
