Takutu Creek to Puruni River, 7 Nov 1944, Fanshawe 2079 (type of Ixora mazarunensis); Bartica-Potaro road, Fanshawe 5524; upper Demerara River, Davis 2457 (type of Ixora davisii).

Discussion:

Patabea coccinea Aubl. Hist. Pl. Guiane 1: 110, t. 43. 1775, non Ixora coccinea L.. 1753.

Cephaelis sessiliflora Willd., Sp. Pl. 1: 979. 1797, non Ixora sessiliflora Baill. 1876-79, nec I. sessiliflora Kurz, 1872.

Ixora mazarunensis Standley, Bull. Torrey Club 75 : 572. 1948.

Type. Upper Demerara River, about 110 miles south of Georgetown, British Guiana, alt 100 ft, 15 Oct 1935, Davis 2457.

Note: Sandwith has already noted (Kew Bull. 1949 : 260. 1949; 17(2): 257. 1963) that Ixora mazarunensis Standley and Cephaelis sessiliflora Willd., as well as Patabea coccinea Aubl., are synonymous with Ixora davisii, and I agree with his conclusions after careful study of the specimens involved.
