A revision of the Puerto Rican species of lepanthes (Orchidaceae)

Six species of the orchid speciesLepanthes are described as new. A seventh species,L. sanguined, previously known only from Jamaica, is reported from Puerto Rico. The current misspelling ofL. selenitepala, the only species of the genus previously reported from Puerto Rico, is corrected. A key to the eight Puerto Rican species ofLepanthes is presented, and the value of several interesting taxonomic characters is discussed. The possibility of apogamy in this genus is raised, and detailed biosystematic investigations are indicated as necessary for a complete understanding of the group.     

Lepanthes variabilis (Orchidaceae: Pleurothallidinae), a new endemic species from Costa Rica

Lepanthes variabilis, a new species from Costa Rica, is described and illustrated. It is endemic to the northern part of the Talamanca mountain range, from 2750–2850 m. It is compared to the similar L. minutilabia, which also occurs in Costa Rica.     

New species of Peruvian Orchidaceae III

Sixteen new species are proposed in the generaAckermania, Dressleria, Epidendrum, Maxillaria, Oncidium, Rodriguezia, Sigmatostalix, andTrigonidium. All new species are illustrated.Maxillaria vittariifolia L. O. Williams is newly recorded for Peru. A key is provided forTrigonidium of Peru.Trigonidium loretoense Schltr. andT. peruvianum Schltr. are lectotypified.     

A revision of epidendrum subgenus epidanthus (Orchidaceae)

Epidendrum subgenusEpidanthus (L. O. Williams) Barringer (Orchidaceae) is a group of small, slender-stemmed epiphytes formerly classified in the genusEpidanthus L. O. Williams. The seven species are distributed from southern Mexico to Columbia in wet forests, usually above 1000 m in elevation. Species of subgenusEpidanthus are distinguished from the rest ofEpidendrum by their linear leaves, slender stems, and two pollinia. The new speciesEpidendrum aurigineum is described and the new nameEpidendrum, insolatum is created forE. crassum (Dressler) Mora-Retana & J. García.     

A revision of Habenaria section Macroceratitae (Orchidaceae) in Brazil

Habenaria sect.Macroceratitae from Brazil is revised, and seven species are recognized:H. bractescens, H. gourlieana, H. johannensis, H. longicauda, H. macronectar, H. nabucoi, and the newly describedH. paulistana. A main feature of these species is the presence of long, separated, involute stigmatic processes.Habenaria bractescens, H. gourlieana, H. johannensis, andH. macronectar are distributed mainly from central and southeastern Brazil to southern Brazil and southern South America, whereasH. longicauda andH. nabucoi are distributed mainly from west central, southeastern and northeastern Brazil to northern South America.Habenaria paulistana is restricted to the state of São Paulo.Habenaria bradei, H. juergensii, andH. sartoroides are lectotypified, andH. kleyi is neotypified. The identity ofH. fastor is discussed andH. nabucoi is recognized as the valid name for this species. Seven other species previously placed in sect.Macroceratitae are sufficiently distinct and are removed from the section.     

New species and records of West Indian Alleculidae (Coleoptera)

Lobopoda wittmeri n. sp. is described from the Dominican Republic; the male of L. notapuncta Campbell is described for the first time. Lobopoda haitensis, L. notapuncta, and Hymenorus haitius previously known only from Haiti are reported from the Dominican Republic; Allecula ramosi previously known from Puerto Rico is also reported from the Dominican Republic. Hymenorus convexus and H. jamaicensis known previously from the Bahama Islands and Cuba and from Jamaica respectively are reported for the first time from the Cayman Islands.

A key is presented to aid in identification of the Alleculidae of the Cayman Islands and Hispaniola.     

A new species ofLiparis (Orchidaceae) from India

Liparis indiraii spec. nova from India is close toL. alata A. Rich. andL. atropurpurea Lindl.     

The genus Panisea (Orchidaceae), a taxonomic revision

The genus Panisea is revised. A total of 13 taxa have previously been described. In the present revision 7 species are recognized: P. albiflora, P. apiculata, P. demissa, P. distelidia sp. nov., P. tricallosa, P. uniflora and P. yunnanensis. A new variety, P. tricallosa var. garrettii is proposed.     

A new species of Omphalanthus (Lejeuneaceae) from Cuba

Abstract

The new species Omphalanthus baracoensis, from the Yunque de Baracoa plateau, southeastern Cuba, is described and illustrated. The species is related to the widely distributed Omphalanthus filiformis, but differs in the presence of a large tooth at the lobule apex.     

A new species of Bursera (Burseraceae) from Cuba

A revision of Bursera in the Greater Antilles has revealed the first new species of the genus to be described from the Caribbean in almost 45 years. Bursera gibarensis is known only from coastal scrub on dogtooth limestone near Gibara in Holguín Province.     

A newZornia species in the Flora of Cuba

A newZornia species from Cuba, the endemicZornia arenicola sp. nova, is described. It was found on moving sand dunes between the town of Guane and the village of Cortes (Pinar del Rio province).
