Taxonomie : "This species has been reported (e.g., Keeley 1982, 2001; Nelson 2008; Turner 2007) in Central America, with
L. canescens in synonymy. Here, following Clewell (1975), Elias (1975), Nash (1976), and Robinson (1990, 1999), I recognize
L. canescens (characterized in part by its usually papillose-setulose or glandular corolla tube) as distinct from
L. arborescens (characterized in part by its glandular corolla lobe apices), the latter being interpreted as endemic to the West Indies."
