Type. “In sylvis montosis Martinicae,” West Indies, Jacquin.

This is primarily a species of the AVest Indies, specimens having been seen from the islands of Martinique, St. Kitts, Nevis, Cuba, Montserrat, Virgin Islands, Hispaniola, Grenada, Puerto Rico, St. Vincent, St. Thomas, St. Jan, Tortola, Dominican Republic, Dominica, and Guadeloupe. The AVest Indian material has mainly white corollas, as in the specimen from Venezuela, cited above, although fleshy-colored and pink corollas have also been recorded on the specimens examined.

Jacquin’s plate shows nearly sessile or very shortly pedunculate inflorescences. This species has the primary peduncles much shorter than in Ixora agostiniana Steyermark, and the common peduncle is practically not developed.

The Fendler specimen cited is a fragment within a packet showing three fruits on pedicels ranging from 1.5 mm long (central fruit) to 7 mm long on a lower singly produced fruit; the common peduncle is 4 mm long, and the rachis between the lowest and highest fruit is 6 mm long; one of the spreading bracts is lanceolate and 5 mm long.
