    Tipo y Observaciones

    Material Tipo: Basónimo: Cleome psoraleifolia DC.
    Observaciones: Phenology.- Tarenaya psoraleifolia is collected with flowers and fruits throughout the year. Discussion.- Tarenaya psoraleifolia resembles T. parviflora and it is very difficult to distinguish them by vegetative features. However, T. psoraleifolia has obovate white petals, 5–6 × 2.5–3 mm (vs. oblanceolate, white to deep purple, 3–4 × 1.5 mm), a conic nectary (vs. disciform), filaments 20–23 mm long (vs. 10–16 mm), and capsules on gynophores 21–25 mm long (vs. 5–15 mm).
