GENUS INDEX

GENUS CODE: HOUST
GENUS SCIENTIFIC: Houstonia
GENUS AUTHORITY: L.
GENUS COMMON: Bluet
GENUS SUMMARY: The generic limits of Houstonia, Hedyotis, Oldenlandia, and Stenaria have been controversial, with much shuffling of generic configuration. It now appears that Houstonia should be recognized as a genus separate from Hedyotis and Oldenlandia, with Stenaria included in Houstonia (Guo et al. 2013; Wikström et al. 2013, and other references).
GENUS IDENTIFICATION: Identification notes: In the key below, all leaf measurements and length/width ratios are based on median cauline leaves.

SCIENTIFIC NAME: Houstonia purpurea
COMMON NAME: Summer Bluet
SYNONYMY: [= F, S; = Houstonia purpurea Linnaeus var. purpurea - G, K, Pa, Va, WV, X, Y, Z; < Houstonia purpurea - Mo, RAB, W, WH3; < Hedyotis purpurea (Linnaeus) Torrey & A. Gray - C, Q; = Hedyotis purpurea (Linnaeus) Torrey & A. Gray var. purpurea]
