28 July 2016 New combinations in Ovieda (Lamiaceae) for Cuba and Hispaniola
Author Affiliations +
Abstract

All endemic species of Hispaniola and Cuba that were formerly assigned to Clerodendrum, with the exception of Volkameria aculeata (or C. aculeatum), are transferred to Ovieda, based on morphological and phytogeographical evidence. A full synonymy, with citation of types, is given for all of them, and the necessary seven new combinations are validated.

Introduction

The name Ovieda L. was validly published by Linnaeus (1753) for a genus with a single species, O. spinosa L., from “America meridionali” (in fact from the Caribbean island of Hispaniola). Subsequently, several additional species were added to Ovieda, some newly described (e.g. O. mitis L. 1763; O. ovalifolia Juss. 1806; O. verticillata Roxb. ex D. Don 1825), some transferred from other genera (e.g. O. inermis (L.) Burm. f. 1768 and O. aculeata (L.) Baill. 1891 [non (Sweet) Klatt 1864], both from Volkameria L.). All were later included in Clerodendrum L. (e.g. by Briquet 1894).

The wide circumscription of Clerodendrum prevailed until recently, when molecular evidence showed it to be unnatural. Using chloroplast DNA sequence data, Yuan & al. (2010) restricted the genus Clerodendrum to Old-World taxa, placing the New-World representatives formerly assigned to it in two other Linnaean genera, Ovieda and Volkameria. The former they considered as unispecific: O. spinosa, the species providing its type and the only one they had used in their analysis, being endemic to Hispaniola. The remaining New World species they placed in what Steane & al. (1997) had identified as a clade of “pantropical coastal Clerodendrum” species, now assigned to Volkameria, a genus represented on the Caribbean islands by its nomenclatural type, V. aculeata L. (Yuan & al. 2010).

Yuan & al. (2010) did not mention the remaining autochthonous Caribbean Clerodendrum species, which were not studied by them. By implication, one might conclude that they were considered as belonging to Volkameria. However, they appear to be closely related to, and in my opinion congeneric with, Ovieda spinosa rather than V. aculeata. This conclusion is not only supported by similarity of general habit and habitat, but also by details of morphology. In major characters considered by Yuan & al. (2010) as distinguishing Volkameria and Ovieda, the Caribbean island endemics agree with O. spinosa. The young branches are tuberculate by prominent lenticels; the leaves are large, often with a ± spinulose-denticulate margin and with a reticulum of abaxially prominent veins.

According to Yuan & al. (2010), the fruit is a drupe in both genera, but has four one-seeded locules in Volkameria and only two one-seeded locules in Ovieda (however, elsewhere in the same paper, they state that the fruit was “not recorded recently”).

Material and methods

The present revision is based on field observations in different places of Cuba and the study of herbarium material with the aid of a binocular dissecting microscope Wild M5A at up to 100× magnification. Fruits were soaked in tap water and boiled until mollified. Specimens were studied at, or obtained on loan from, the following herbaria (abbreviated in conformity with Thiers 2016+): A, B, BM, F, G, GH, HAC, HAJB, HIPC, JE, K, MO, NY, P, PAL-Gr, S and US. Digital images available via the Internet (A, F, G, P, K, KW, NY, S, YU) and in microfiches (G in B) were also studied.

Results and Discussion

Recent studies on Ovieda spinosa (e.g. García & al. 4890, PAL-Gr) and the other Caribbean island endemics species lead the author to the conclusion that they all have drupes with two one-seeded pyrenes.

Morphological and phytogeographical evidence is sufficiently conclusive to justify inclusion in Ovieda of all endemic species of Hispaniola and Cuba that were formerly assigned to Clerodendrum. During preparation of the Lamiaceae treatment for the Flora de la República de Cuba these species were recently revised by me, and their synonymy established. This revision results in the need for seven new combinations, validated as follows:
