Abstract
ybianthus pittierianus Pipoly & Ricketson (Myrsinaceae) is described from Tobago, and its taxonomic relationships are discussed. This species is often confused with C. rostratus (Hassk.) G. Agostini owing to its free portions of the filaments being longer than the anthers, and leaves with similar elliptic shapes and with petioles less than 1.2 cm. However, C. pittierianus is easily distinguished from C. rostratus by the former's leaf blade apices abruptly acute to short-acuminate (vs. long-acuminate to caudate), with secondary veins in 18 to 24 pairs (vs. 28 to 32 pairs), corollas 2.4–3 mm (vs. 2.1–2.5 mm), and corolla lobes chartaceous (vs. carnose) and adaxially glabrous (vs. densely glandular-granulose). Cybianthus pittierianus is known from the Coastal Cordillera of Venezuela and Tobago, in cloud forests on potassium- and magnesium-rich but nitrogen- and organically poor soils over metamorphic gneiss or schist rocks.
