Uragoga domingensis Urb., Repert. Sp. Nov. 17: 7. 1921.

Cephaelis domingensis (Urb.) Standl., Field Mus. Publ. Bot. 4: 335. 1929, not Psychotria domingensis Jacq. Enum. Pl. Carib. 16. 1760.

This species has been confused with Psychotria aubletiana var aubletiana (Cephaelis axillaris Sw.), and was not taken up in Molino’s revision of the genus Cephaelis for the West Indies, Mexico, and Central America (Ceiba 4(1): 1-38. 1953).

It may be separated from P. aubletiana var aubletiana by the shorter petioles 3-7 mm long, petioles hirtellous beneath, leaves averaging much smaller (3.5-7.5 × 1-2.5 cm), mainly eciliate calyx lobes with glands frequently at the apices of the lobes, smaller and fewer-flowered heads 0.6-1 cm long by 0.7-1.2 cm broad, shorter internodes, densely hirtellous or hirsutulous stems, smaller stipules 3-6 mm long with triangular-lanceolate, subacute to acute lobes 0.7-2 mm long and hirtellous without on the sheath and lobes, the hairs conspicuous and coarser, and proportionate length of corolla lobes to tube difference. It is named in honor of Dr. Alain H. Liogier, who has so greatly advanced our knowledge of the West Indian flora, especially of Cuba and Santo Domingo.
