“…Didactyle, embora ambas compartilhem o mesmo hábito. Dentre as Orchidaceae, o mesofilo varia entre homogêneo e heterogêneo (Kurzweil et al 1995, Morris et al 1996, Oliveira & Sajo 1999, Pires et al 2003, Silva et al 2006, Carlsward & Stern 2009, Aybeke et al 2010, Aybeke 2012, bem como dentro do gênero Bulbophyllum (Gravendeel et al 2014). Essa característica está claramente associada às espécies que toleram grande exposição ao sol, como registrado para Cymbidium (Yukawa & Stern 2002).…”

Bulbophyllum sect. Didactyle e B.sect. Xiphizusa são grupos monofiléticos irmãos, inseridos no clado neotropical do gênero. As espécies ocorrem como epífitas ou rupícolas em áreas montanhosas com predomínio dos campos rupestres. O objetivo foi descrever comparativamente a anatomia dos órgãos vegetativos de 13 espécies dessas seções. O trabalho evidencia pela primeira vez a secreção lipofílica dos tricomas na folha jovem; caracteres xeromorfos uniformes entre as duas seções, como a cutícula espessa, presença de idioblastos, parênquima aquífero e fibras junto aos feixes vasculares; a ausência de cristais prismáticos na raiz e bulbo nas espécies de B.sect. Didactyle e a ausência de idioblastos com espessamento espiralados na raiz, espessamento na parede epidérmica do pseudobulbo e predomínio de mesofilo heterogêneo nas folhas das espécies de B. sect. Xiphizusa podem ser considerados estados de caractere sinapomórficos para as seções mostrando a importância da anatomia em estudos sistemáticos.

“…Most orchid species have 1 layer of exodermis. The number of exodermal layers can be more than one layer, such as in some Ophrys ranged from 1 to 4 (Aybeke et al 2010). Orchids of Sempu Island in the present study exhibited exodermis cell wall thickening with various patterns of exodermis cell wall thickening.…”

“…Terrestrial orchids also have various number of velamen layers: No velamen in Zeuxine gracilis (Muthukumar et al 2011), single layer of velamen, but was partly replaced with an exodermis in Neottia nidus-avis, Limodorum abortivum, Serapias orientalis (Aybeke 2012). Ophrys iricolor and O. morio have epivelamen without any velamen (Aybeke et al 2010). Other terrestrial orchids have a uniseriate velamen, such as Habenaria rhodocheila (Stern 1997) Cranichis cochleata, Ponthieva ephippium, Goodyera brachyceras, and Ludisia discolor (Figueroa et al 2008).…”

“…The presence or absence of tilosomes was also reported in other orchid species. Tilosomes were present in Prescottia tubulosa and Prescottia stachyodes (Prescottiinae) and in many species of Spiranthinae (Figueroa et al 2008; some Ophrys (Aybeke et al 2010), while tilosomes were absent in some species of Goodyerinae, Cranichidinae and Manniellinae (Figueroa et al 2008).…”

Morphology, anatomy, and mycorrhizal fungi colonization in roots of epiphytic orchids of Sempu Island, East Java, Indonesia

Roots of orchids have important role for survival, adaptation, water and nutrient absorption, and as a place of symbiosis with mycorrhizal fungi. The present study aimed to investigate the morphology, anatomy, and mycorrhizal status in roots of orchids of Sempu Island, Indonesia (Ascochilus emarginatus, Taeniophyllum biocellatum, and Thrixspermum subulatum), in relation to their adaptation to their habitat of coastal forests of Sempu Island. These orchids have different morphological characters; Ascochilus emarginatus and Thrixspermum subulatum are leafy orchids, while Taeniophyllum biocellatum is a leafless orchid. The results showed that all orchids have small number of velamen layers (1-2 layers) as an adaptation to the relatively humid condition. Cell wall thickenings of velamen, exodermis, and endodermis are structural adaptation of all orchids to the relatively high intensity of illumination, to reduce water loss because of transpiration. Mycorrhizal fungi colonization which is important for nutrient acquisition occurs in cortical cells. All orchids have differences in their cell shape, size, and specific characters, such as chloroplasts. The leafless Taeniophyllum biocellatum has many chloroplasts in the cortical root cells that support the photosynthesis process, while A. emarginatus and T. subulatum are lack of chloroplasts in their cortical root cells.

“…Orchidaceae is one of the most successful plant families in evolution and speciation, resulting in approximately 25.000 species across the world with highly various morphological and anatomical characters (Dressler 1993). Anatomical characters of orchids have been widely studied in a wide range of species within tribes, subtribes, and genera levels, such as tribe Calypsoeae (Stern and Carlsward 2008); subtribes Laeliinae (Stern and Carlsward 2009); Aeridinae, Angraecinae and Aerangidinae (Carlsward et al 2006); Stanhopeinae (Stern and Whitten 1999), Orchidinae ; Habenariinae , Oncidiinae (Stern and Carlsward 2006); and genera Caladenia (Pridgeon 1993), Dendrobium sections Aporum and Rhizobium (Carlsward et al 1997), Ophrys, Orchis and Dactylorhiza (Aybeke et al 2010).…”

Abinawanto, Sophian A, Effendi PS, Siswantining T. 2018. Short Communication: Variation in vocal cord morphometric characters among dangdut type and the slow type Gaga Chicken. Biodiversitas 19: 1902-1905. Gaga chicken is one of the ornamental chicken originating from Sidendreng and Rapang (South Sulawesi). Gaga chicken has a unique crowing sound, like people laugh. Gaga’s chicken which has a long and fast crowing sound known as the dangdut type, while those with short and slow crowing sound are known as slow type. Study was conducted in Pinrang (South Sulawesi), where one of the pure strains are located. Samples were collected from Kanie, Bullo, Macege, Rappang, and Sidenreng. The purpose of study was to determine the characteristics of the vocal cord morphometric among the dangdut type and the slow type of Gaga’s chicken. All of the morphometric data were recorded and analyzed by Mean Test, using SPSS (version 22). The results showed that there was no significant difference ( = 0.010) among the dangdut type and the slow type based on syrinx morphometric. Meanwhile, according to the trachea muscle morphometric the results showed that the trachea muscle of dangdut type was longer than the slow type ( < 0.010). In addition, either the right or the left trachea muscle of dangdut type was longer than either the right or the left trachea muscle of the slow type ( < 0.010).
