Stachytarpheta jamaicensis is a species of plant in the family Verbenaceae, native throughout the Caribbean, [3] including Florida. [4] It has many common names including blue porterweed, blue snake weed, bastard vervain, Brazilian tea, Jamaica vervain, [5] light-blue snakeweed, [6] and, in St. Croix, worryvine.source? It usually is found along country roadsides, and it also grows well as a ruderal plant on disturbed terrain.

Contents

A similar plant, Stachytarpheta cayennensis , which is an invasive species in Florida, [7] is sometimes mistaken for S. jamaicensis. [8]

It is unclear whether S. indica is a separate species. [9]

Medicinal Uses

The fresh leaves are consumed in bush tea as a “cooling” tonic and blood cleanser, to treat “asthma” and “ulcerated stomachs”. [10]

Tea brewed from this species has been shown to cause a dose-dependent "fall in [the] blood pressure" of normal rabbits. However, the tea has also been observed to cause a "mild non-dose dependent systematic toxicity" in various tissues throughout the body, "such as congestion, fatty changes, and necrosis in liver, blood vessels, kidney, lung and testis, but the brain, eyes, intestines and heart were essentially normal." [11]

<i>Junonia evarete</i> Species of butterfly

Junonia evarete, the tropical buckeye or South American tropical buckeye, is a South American butterfly of the nymphalid (Nymphalidae) family. It has characteristic eye spots on the wings, which have a wingspan between 4.5 and 6.5 cm. This butterfly is easily confused with Junonia genoveva, the mangrove buckeye. Not only have the common names mangrove and tropical buckeye been confused, but the butterflies themselves have been sometimes misidentified in past literature because the two species have many variations, subspecies and seasonal forms, which makes them difficult to identify or differentiate. Phylogenetic studies demonstrate the separation of evarete and genoveva, but evidence suggests that subspecies and perhaps more species await their descriptions within this group.
