Orchidaceae Em Um Fragmento De Floresta Semidecídua De Encosta Na Região Sul Do Estado Do Espírito Santo, Sudeste Do Brasil
Hoehnea 41(2): 247-268, 5 fig., 2014 Orchidaceae em um fragmento de Floresta Semidecídua de encosta na região sul do Estado do Espírito Santo, Sudeste do Brasil Amauri Herbert Krahl1,4, Antônio Jesus Dorighetto Cogo2 e Jefferson José Valsko3 Recebido: 7.05.2013; aceito: 9.01.2014 ABSTRACT - (Orchidaceae in a fragment of semideciduous slope forest in the southern Espírito Santo State, Southeastern Brazil). The present study aimed to inventory and elaborate descriptions and illustrations for the species of Orchidaceae found in a forest located in the southern Espírito Santo State, a region of few botanical studies, featuring a poorly known flora. During the study, 25 species were found and distributed into 21 genera. The majority of the species were epiphytic, represented by 16 species, followed by rupiculous, terrestrial, and mycoheterotrofic species. Most species flourished during the hot and humid period. Furthermore, the study revealed the presence of an endemic species and three new records for the State. Keywords: Atlantic Forest, conservation, orchids, taxonomy RESUMO - (Orchidaceae em um fragmento de Floresta Semidecídua de encosta na região sul do Estado do Espírito Santo, Sudeste do Brasil). O presente trabalho teve como objetivo inventariar e elaborar descrições e ilustrações para as espécies de Orchidaceae encontradas em um fragmento de Floresta Semidecídua localizado no sul do Estado do Espírito Santo, região de poucos estudos, caracterizando uma flora ainda pouco conhecida. Durante o estudo, 25 espécies distribuídas em 21 gêneros, foram registradas. A forma de vida predominante foi a epifítica, caracterizada por 16 espécies, seguida pela rupícola, terrícola e micoheterotrófica. A maior parte das espécies floresceu no período quente e úmido. -

Mating Systems in the Pleurothallidinae (Orchidaceae): Evolutionary and Systematic Implications
LANKESTERIANA 11(3): 207—221. 2011. MATING SYSTEMS IN THE PLEUROTHALLIDINAE (ORCHIDACEAE): EVOLUTIONARY AND SYSTEMATIC IMPLICATIONS EDUARDO LEITE BORBA*, ARIANE RAQUEL BARBOSA, MARCOS CABRAL DE MELO, SAMUEL LOUREIRO GONTIJO & HENRIQUE ORNELLAS DE OLIVEIRA Departamento de Botânica, Instituto de Ciências Biológicas Universidade Federal de MinasGerais, Belo Horizonte, MG, 31270-901, Brazil * Corresponding author: [email protected] ABSTRACT. We developed a project addressing the determination of the reproductive system through experimental pollinations of species in the major genera representing all major lineages of Pleurothallidinae in order to determine occurrence of self-incompatibility in the subtribe, in which group it has possibly appeared for the first time, and how many times it has evolved. Additionally we surveyed the floral biology of species ofOctomeria , a genus with morphological characters typical of bee-pollinated flowers that was previously regarded as mellitophilous. At the moment, all but one of the species studied in selected large genera of the major lineages (Acianthera, Anathallis, Masdevallia, Octomeria, Specklinia, and Stelis) are self-incompatible. The species studied may possess complete, strong or partial self-incompatibility. We found two different sites where self-incompatibility reactions occur, the stigma and the stylar channel, and both sites were not found in the same genus except for Anathallis. In Anathallis, the two groups that differ morphologically (formerly Pleurothallis subgen. Specklinia sect. Muscosae -

Ackerman Tag der mündlichen Prüfung: 06.02.2004 Pleurothallis obliquipetala Acuña & Schweinf. Für Jakob und Julius, die nichts unversucht ließen, um das Zustandekommen dieser Arbeit zu verhindern. Zusammenfassung Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba z.B. mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der antillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba – Jamaica – Hispaniola, einer Region, die 95 % der antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind. -

Lycaste Lye-KASS-Tee
Lycaste lye-KASS-tee Lycastes are deciduous in various degrees, from the strongly deciduous, yellow-flowered species like Lycaste aromatica that flowers from leafless pseudobulbs to the evergreen types like Lycaste skinneri with pseudobulbs that retain their leaves at flowering. This genus produces large, long-lasting, showy, triangular flowers that are waxy. The plants are distinctive for their roundish pseudobulbs and broad, plicate (pleated) leaves. Culture for the hybrid genus Angulocaste (Lycaste ϫ Anguloa) follows the culture for the Lycaste parent. LIGHT requirements vary. Deciduous recommended during active growth species require light conditions as for cat- (usually summer); some growers spread tleyas — 2,000 to 4,000 foot-candles or 50 blood meal on the top of the potting medi- to 70 percent shade.

The study area is located in the southwestern Colombia and it covers about 22 140 km2 of land across 4 physiographic units. All analysis are based on the fieldwork and on the revision of the herbarium material. A list of 572 orchid species occurring in the department of Valle del Cauca is presented. Two species, Arundina graminifolia and Vanilla planifolia, are non-native elements of the studied orchid flora. The greatest species diversity is observed in the montane regions of the study area, especially in wet montane forest. -
