Discussion:
Type. VENEZUELA. Territorio Amazonas: Summit, Cerro Moriche, Rio Ventuari, 1250 m alt, 15 Jan 1951, sprawling shrub to 2 m high; young leaves scarlet; flowers scarlet; fruit green, Maguire, Cowan & Wurdack 30945 (holotype NY). Paratypes. VENEZUELA. Amazonas: Cerro Sipapo (Paraque), Cafio Negro, 1630 m alt, 15 Dec 1948, Maguire & Politi 27685; Cerro Sipapo (Paraque), southeast slope Park I, 1500-1820 m alt, 12 Dec 1948, Maguire & Politi 27651; Cerro Sipapo (Paraque), terraces E of Campo Grande, 8 Dec 1948, Maguire & Politi 27563-B; Cerro Sipapo (Paraque), upper Caño Negro, 6 Jan 1949, Maguire & Politi 28196. This taxon has the habit of Thibaudia truncata A. C. Smith, but the filaments are unequal and obviously of two lengths, and the pedicels, calyx, and coroUa are glabrous. Among the species of Orthaea. this taxon is related to other species in the assemblage related to O. apophysata (Griseb.) A. C. Smith.
