Sci. 32(1):137-150. 138 BULLETIN FLORIDA STATE MUSEUM VOL. 32(1) INTRODUCTION In the course of field work in Parc National Pic Macaya, Massif de la Hotte, Haiti (Judd 1987), the following three undescribed species were collected, and are described below. Other new angiosperm taxa resulting from field work in connection with a recent biogeophysical inventory of Morne la Visite and Pic Macaya National Parks have been (or are being) described elsewhere ; these include: Wallenia formonensis Judd (Judd f986a), Micropholis polim (Griseb.) Pierre subsp. hotteana Judd (Judd 1986b),Ila blancheana Judd (Judd 19860, Mecranium revolutun Skean & Judd (Skean & Judd 1986), Duranta arida Britton & Wilson subsp. serpentina Sanders & Judd (Judd & Sanders 1986), Meriania brevipedunculata Judd & Skean and M. panifolia Judd & Skean (Judd & Skean 1987), and Salvia sp. nov. (Skean & Judd, manuscript). In addition undescribed species of Pilea, Rhytidophyllum, and Ditta were collected. The highly endemic flora of the high elevations of the Massif de la Hotte is poorly known, and our knowledge of the region's flora is based mainly on the extensive collections of E. L. Ekman (see Ekman 1928, and Ekman's unpublished field notes). Continued botanical exploration will likely reveal additional undescribed taxa. ACKNOWLEDGEMENTS Special thanks are due Charles A. Woods, who organized the field trips on which these plants were collected; it is a pleasure to name one of the new species, Ossaea woodsii, in recognition of his significant contributions to the knowledge and preservation of the flora and fauna of Haiti. We thank Rogers McVaugh for his helpful comments concerning the specimens of Lobelia hotteana. Thanks are also due the curators of the herbaria (DUKE, JBSD, NCU, NY, US) from which comparative material of Lobelia, Ossaea, and/or Miconia was borrowed. We are grateful to Kent D. Perkins, registrar of the University of Florida Herbarium, for his help in processing specimen loans, and to Norris W. Williams, keeper of the University of Florida Herbarium, for making available the computer facilities of the herbarium. We also thank Richard A. Howard, Carroll E. Wood, Jr., Michael Canoso, and Walter Kittredge for their assistance during the visit of the first author to the Harvard University Herbaria (A, GH). Finally, we thank Wendy Zomlefer for her fine illustrations and David W. Hall for his helpful comments on the manuscript.

Type: Haiti. Departement du Sud: Massif de la Hotte, Parc National Pic Macaya, moist forest of Pinus occidentalis Sw., open rocky areas, ravine on south slope of Morne Formon, at 1650-1730 m alt., just east of"1650 camp," locally common, 28 January 1984 (flowers) Walter S. Judd 3790 (Holotype, FLAS; isotypes, NCU, NY). The species was also seen (but not collected) at ca 2200 m alt. on open rocky ridge just south of Pic Macaya. Lobelia hotteana probably is related to Lobelia sm'cta Sw., a species restricted to the Lesser Antilles. It differs from this species in its often smaller and less crowded leaves, shorter and fewer-flowered inflorescence, and flowers with smaller corolla lobes and the two smaller anthers with much shorter hair-tufts at the apex (see diagnosis, and McVaugh 1943). This species is also similar to L. christii Urb. (also of the Massif de la Hotte) in that its two smaller anthers are only minutely pubescent at the apex (compared with "very minutely beaded" in L. ch,istii, see McVaugh 1943). Affinity may also exist with L. robusm Graham and L. asswgens L. (R. McVaugh pers. comm.). This new species has been seen only in open rocky areas of moist high- elevation forests of Pinus occidentalis Sw. Associated species include: Agave annWamm Desc., Andropogon glomerams (Walt.) BSP. subsp. pumilus Vasey, Bacchaifs myrsinites (Lam.) Pen, CastiUeja arvensis Schlecht. & Cham., Chaptalia albicans Urb. & Ekm., Eupatoiium,#avidulum Urb. & Ekm., Ganya fa*enii Hook., Gyromenia mynocatpa Griseb., Isachne nkidtfolia (Poir.) Urb., Pteris longifolia L., Rhytidophyllum auriculatum Hook., Rubus spp., Senecio stenodon Urb., and Weinmannia pinnata L. At higher elevations near Pic Macaya the species occurs with some of the above species along with Gaultheria domingensis Urb., Miconia spp., Myrica picardae Krug & Urb., Temstroemia barkeri Ekm. & Schmidt, and Wallenia aqu#blia Urb. & Ekm. Three other members of the Lobeloideae were also collected in the park; these are: Lobelia robusm Graham, L. ronmdifolia Juss., and Siphocampylus sonch(folius (Sw.) McVaugh.

Inflorescences axillary fasciculate cymes, ca 0.4-0.8 cm long, bearing (1)3 to 7 flowers, the axes densely covered with ferrugineous, sessile to short-stalked, globular to irregularly branched or stellate, multicellular hairs. Flowers 4-merous, sessile or nearly so, each associated with 2 linear to narrowly triangular and sparsely pubescent bracteoles, ca 0.7-1.5 mm long, 0.1-0.2 mm wide, with acute apices, and subtended by a narrowly triangular and densely pubescent bract to ca 2 mm long.

Departement du Sud: Massif de la Hotte, Parc National Pic Macaya, cloud forest/ moist pine forest on southern slope of Morne Formon, 1620-1660 m alt., uncommon, 28 January 1984 (old flowers) Walter S. Judd 3802 (A, EHH, FLAS, S, US). Ossaea woodsii probably is related to several morphologically similar species of Ossaea with axillary cymes and small 4-merous flowers, such as 0. scalpm (Vent.) DC., 0. bamhonensis Urb. & Ekm., 0. cun*ila Urb. & Ekm., and 0. semlosa Urb. It differs from these species in indumentum characters (see diagnosis). Ossaea woodgii can be separated easily from 0. barahonensis, 0. semlosa, and 0. curvipila by its lack of stout conical multicellular hairs (i.e. strigose indumentum) on the twigs and abaxial leaf surfaces and shorter hypanthial hairs, and is differentiated from 0. scalpta by its more or less sessile, irregularly stellate hairs on the twigs (vs long-stalked, terminally branching hairs), glabrous petals, and longer external calyx lobes. All of the above mentioned species are endemic to Hispaniola (Moscoso 1943). Ossaea curvipila and 0. setulosa also have been collected in the park, and both are restricted to the high elevations of the Massif de la Hotte. The only other Ossaea known from the Morne Formon region is 0. alloeotricha Urb., which was collected by Ekman near the summit of Morne Formon (see E. L. Ekman H7473, NY!, S!). This distinctive terminal-flowered species is known only from the type gathering. Ossaea woodsii is known only from cloud forests and moist forest with Pinus occidentalis Sw. from ca 1450 to 1780 m on Morne Formon.

Departement du Sud: Massif de la Hotte, Parc National Pic Macaya, ibid., locally common, 6 February 1984 (flower buds) Walter S. Judd 4125 (EHH, FLAS, S , US). Miconia macayana is clearly a member of Miconia Sect . Chaenopleura Benth. & Hook., as indicated by its anthers with elongate slits. This section is extremely diverse in the Greater Antilles, and contains many narrow endemics. Close relatives of M. macayana are not known; however, it is 148 BULLETIN FLORIDA SrATE MUSEUM VOL 32(1) similar to Miconia nkidissima Urb. & Ekm. in indumentum characters and inflorescence structure. Miconia macyana is easily distinguished from the other species of Miconia occurring in the Massif de la Hotte by its combination of fairly small, ovate, extremely coriaceous, and conspicuously crenate leaves, with a characteristic dense covering of ferrugineous, fasciculate-sinuous multicellular hairs, and inflorescences composed of condensed cymose heads. The discovery of this species brings to ten the number of species of Miconia known from the Morne Formon-Pic Macaya region, Massif de la Hotte. These species are: M. apiculam Urb. & Ekm. (ind. M. niedenzuana Urb. & Ekm.), M. barked Urb. & Ekm., M. hypioides Urb. & Ekm., M. laevigata (L.) DC., M. mimbilis (Aubl .) L. 0. Williams, M. ossaeifolia Urb. & Ekm., M. subcompressa Urb. (ind. M. plumien' Urb. & Ekm.), M. tetrastoma Naud., M. xenomcha Urb. & Ekm., and M. macayana Judd & Skean. All have been collected recently by the authors. Seven of these species are endemic to Hispaniola, and six are endemic to the Massif de la Hotte. Miconia macayana is endemic to the Massif de la Hotte of Haiti where it is known only from exposed ridges in moist forests of Pinus occidentalis Sw. and adjacent cloud forests on the southern slope of Pic Macaya at ca 2150- 2200 m alt. Associated species in this area include: Agave antillarum Desc., Bacchan's myrsinites (Lam.)
