A new species of Cyanea (Campanulaceae, Lobelioideae) from Maui, Hawaiian Islands.

ABSTRACT: Cyanea kauaulaensis H. Oppenheimer & Lorence, sp. nov., a new, narrowly endemic species from Maui, Hawaiian Islands is described, illustrated with field photos, and its affinities and conservation status are discussed. It is currently known from 62 mature plants and is restricted to Kaua`ula and Waikapu valleys on leeward western Maui. It differs from all other species of Cyanea by its combination of many-branched habit; glabrous, unarmed, undivided leaves; small, narrow, glabrous corollas with small calyx lobes that do not persist in fruit; and bright orange, subglobose to obovoid fruits.

Clermontiahanaulaensis (Campanulaceae, Lobelioideae), a new, critically endangered species from Maui, Hawaiian Islands

Project description:Abstract Clermontiahanaulaensis H.Oppenheimer, Lorence & W.L.Wagner, sp. nov., a newly discovered, narrowly distributed endemic species, is herein described based on its morphological characteristics and illustrated with field photos and a line drawing. It is currently known only from the slopes of Hana‘ula, in Pōhākea Gulch, Mauna Kahālāwai, west Maui, Hawaiian Islands. It differs from all other species of Clermontia Gaudich. by the combination of its (2)3–4(–5) flowered inflorescence, violet colored perianth often suffused with creamy white streaks or sometimes creamy white with violet-purple irregular veins, (30)35–45(–50) mm long, perianth tube 15–25(–27) mm long, 9–10 mm wide, the lobes 20–26 mm long, (2–)3–3.5 mm wide, with petaloid calyx lobes 1/2–4/5 as long as the petals. A key to the Clermontia species and subspecies occurring on Maui is provided. Its habitat is described. Its conservation status is proposed as critically endangered (CR), and conservation efforts are discussed.

Two new species of Siphocampylus (Campanulaceae, Lobelioideae) from the Central Andes.

Project description:Two species of Siphocampylus (Campanulaceae: Lobelioideae) from the Central Andes of Peru and Bolivia are described, illustrated, and discussed with reference to related species. One species, Siphocampylus antonellii, is endemic to high elevation grasslands of Calca, Peru, while the second, Siphocampylus siberiensis, is endemic to cloud forests of Cochabamba, Bolivia. Both species are robust shrubs that produce tubular pink flowers that are likely pollinated by hummingbirds.

Primers for low-copy nuclear genes in the Hawaiian endemic Clermontia (Campanulaceae) and cross-amplification in Lobelioideae.

Project description:UnlabelledPremise of the studyPrimers were developed to amplify 12 intron-less, low-copy nuclear genes in the Hawaiian genus Clermontia (Campanulaceae), a suspected tetraploid. •Methods and resultsData from a pooled 454 titanium run of the partial transcriptomes of seven Clermontia species were used to identify the loci of interest. Most loci were amplified and sequenced directly with success in a representative selection of lobeliads even though several of these loci turned out to be duplicated. Levels of variation were comparable to those observed in commonly used plastid and ribosomal markers. •ConclusionsWe found evidence of a genome duplication that likely predates the diversification of the Hawaiian lobeliads. Some genes nevertheless appear to be single-copy and should be useful for phylogenetic studies of Clermontia or the entire Lobelioideae subfamily.

Melicope oppenheimeri, section Pelea (Rutaceae), a new species from West Maui, Hawaiian Islands: with notes on its ecology, conservation, and phylogenetic placement.

Project description:Melicope oppenheimeri K.R. Wood, Appelhans & W.L. Wagner (section Pelea (A. Gray) Hook. f., Rutaceae), a rare endemic tree from West Maui, Hawaiian Islands, is described and illustrated with notes on its ecology, conservation, and phylogenetic placement. The new species differs from Hawaiian congeners by its carpels basally connate 1/5, narrowed into a strongly reflexed beak 10-15 mm long. It also differs in a combination of leaves with 7-10 pair of secondary veins; cymes to 3 cm long; peduncles 5-6.5 mm long; flowers perfect; capsules 4-9 × 40-52 mm; and a densely appressed short-sericeous ovary. Melicope oppenheimeri is known only from an isolated cliff-base plateau in upper Waihe'e Valley, West Maui. Its discovery brings the number of recognized Melicope J.R. Forst. & G. Forst. species in the Hawaiian Islands to 49. A table is included indicating the conservation status of Hawaiian Melicope and Platydesma H. Mann., which is nested within Melicope sect. Pelea. Melicope oppenheimeri falls into the IUCN Critically Endangered (CR) Red List category.

New and resurrected Hawaiian species of pilo (Coprosma, Rubiaceae) from the island of Maui.

Project description:Two species of Coprosma (Rubiaceae) J.R.Forst. & G.Forst. are described from the island of Maui of the Hawaiian Archipelago. A newly described taxon, Coprosma cordicarpa J.Cantley, Sporck-Koehler, & M.Chau, sp. nov. is locally common in medium to high elevation dry forests and shrublands of leeward East Maui. The second taxon is resurrected from the synonymy of Coprosma foliosa A.Gray as Coprosma stephanocarpa Hillebr. and occurs in mesic to wet rainforests of both East and West Maui. Both taxa are segregated from Coprosma foliosa, with which they share similar morphological characters. A conspicuous and persistent calyx of the fruit and various floral characters most easily differentiate both taxa from other Hawaiian taxa. The newly described Coprosma cordicarpa is further distinguished from Coprosma stephanocarpa by a central constriction of the fruit with a depressed apex, which gives it a characteristic heart shape. Furthermore, the taxa are largely separated phenologically, ecologically, and geographically. Descriptions, conservation status, and specimens examined for the new species are included.

<i>Athyrium haleakalae</i> (Athyriaceae), a new rheophytic fern species from East Maui, Hawaiian Islands: with notes on its distribution, ecology, and conservation status.

Project description:Athyrium haleakalae K.R. Wood & W.L. Wagner (Athyriaceae), a small lithophytic fern from East Maui, Hawaiian Islands, is described and illustrated. Notes on its distribution, ecology, and conservation status are also presented. The new species appears to be an obligate rheophyte, preferring sites of fast moving water along concave walls of streams and waterfalls. Athyrium haleakalae differs from the only other known Hawaiian Athyrium, Athyrium microphyllum (Sm.) Alston, in having rhizomes 1-3 cm long and lanceolate blades 1- to 2-pinnate-pinnatifid, 3-8(-11) × 1-3(-4) cm, as compared to Athyrium microphyllum having rhizomes (10-)15-30 cm long and ovate to ovate-triangular blades 3-pinnate-pinnatifid to 4-pinnate, 30-82 × 20-50 cm.
