Lectotype. Cuba, Jacquin.
I am selecting the plant collected from Cuba as lectotype. Material in the Paris Herbarium from “La Havanne,” Cuba (Herb. Maire) shows the small, glabrous leaves, relatively short, glabrous peduncles, and relatively short corollas characteristic of the West Indian material passing as G. parviflora. Another specimen in the Paris herbarium of the glabrous, small-leaved plant with glabrous peduncles labelled Laugieria odorata Jacq. in Lamarck’s handwriting comes from Martinique, collected in 1792 by Terrasson 106.
The selection of the Cuban plant as lectotype would seem to be more in agreement with two elements in Jacquin’s original description: (1) his pl. 177, fig. 21 of Stirp. Select. Am. shows a corolla tube about 9 mm long and with five lobes about 2.5-2.7 mm long, the complete corolla length of 11.5-12 mm; (2) his reference (Stirp. Select. Am. p. 64) to the leaves as “glabra” fits the Cuban plant.
Since Jacquin indicated both Cartagena, Colombia, and Cuba as type localities for his Laugieria odorata, it should be noted that modern collections made in the vicinity of Cartagena (Dugand 994 and Haught 4174) disagree in several respects from Jacquin’s original description, namely in having mainly tetramerous corollas with longer tubes, leaves generally pubescent beneath on the midrib and nerves, and pubescent peduncles which are frequently as long as the leaf blade. Standley (Field Mus. Publ. Bot. 7: 65. 1930 and N. Am. Fl. 32: 259. 1934) gives Cartagena, Colombia, as the type locality for G. odorata. I have interpreted the Colombian plants as belonging to the taxon with longer corollas and more pubescent leaves and peduncles, treated here under G. divaricata (H. & B.) Standi. Specimens which have previously passed under the name G. parviflora, in accord with my present interpretation, must receive the binomial of G. odorata (Jacq.) Lam.
Topotypical material of G. parviflora Vahl from St. Croix has a tetramerous flower, corollas 12.5 mm long with tube 9.5 mm long, leaves below glabrous on surface with sparse short, strigillose pubescence on the midrib and lateral nerves, 1.8-3.2 × 1-1.8 cm, and a glabrous or sparsely appressed-pubescent peduncle 1.8-2 cm long. This is the taxon represented in all the Lesser Antilles, from which G. parvifolia Sw. was described from the island of St. Bartholomew; it is also represented in Cuba and Puerto Rico. The greater glabrity of its leaves and peduncles contrast with the more pubescent development found in G. elliptica, which is commoner in the Greater Antilles, especially in Cuba, Jamaica, and Hispaniola.
