Sinningia lutea (Gesneriaceae), a new species from Southern Brazil
Brittonia, 2012Co-Authors: Cristiano Roberto Buzatto, Rodrigo B. SingerAbstract:Sinningia lutea (Gesneriaceae) is described and illustrated as a new species from the Pampa Biome, in Southern Brazil. In the literature, this species has hitherto been confused with S. allagophylla from which it can be easily separated using a set of floral and vegetative features (especially corolla color and size and leaf shape). An Artificial Key to separate S. lutea from S. allagophylla and S. curtiflora (another sympatric species, with some morphological similarities) is presented. Some ecological remarks on the differential distribution of S. lutea and S. allagophylla are also made.

Sinningia lutea (Gesneriaceae), a new species from Southern Brazil
Brittonia, 2012Co-Authors: Cristiano Roberto Buzatto, Rodrigo B. SingerAbstract:Sinningia lutea (Gesneriaceae) é descrita e ilustrada como uma espécie nova para a ciência, provinda do Bioma Pampa, no Sul do Brasil. Na literatura local precedente, esta espécie tem sido confundida com S. allagophylla , espécie da qual pode ser facilmente separada utilizando um conjunto de caracteres de morfologia floral e vegetativa (especialmente a cor e o tamanho da corola e o formato das folhas). Se fornece uma chave dicotômica Artificial para separar S. lutea de S. allagophylla e S. curtiflora (outra espécie simpátrica com algumas semelhanças morfológicas). Efetuam-se também algumas considerações ecológicas sobre a distribuição geográfica diferenciada de S. lutea e S. allagophylla .

New records of lichen genus thelotrema ach. (Thelotremoid graphidaceae) from South Korea.
Mycobiology, 2012Co-Authors: Santosh Joshi, Udeni Jayalal, Jung Shin Park, Jae Seoun HurAbstract:This study illustrates the status of thelotremoid Graphidaceae in South Korea. The taxonomy and systematics of thelotremoid lichens in the country have recently advanced greatly. Following the earlier known taxa from the group, four new records of the genus Thelotrema are reported and described briefly. An Artificial Key for all known species under thelotremoid group of Graphidaceae from South Korea is also provided.

Notes on Species of the Lichen Genus Canoparmelia Elix & Hale in South Korea
Mycobiology, 2012Co-Authors: Udeni Jayalal, Santosh Joshi, Jung Shin Park, Jae Seoun HurAbstract:Detailed descriptions of five species of the lichen genus Canoparmelia Elix & Hale. are presented. Until now, three species of the genus Canoparmelia, including C. apata (Krempelh.) Elix & Hale, C. owariensis (Asah.) Elix, and C. texana (Tuck.) Elix & Hale have been reported in South Korea. Canoparmelia carneopruinata (Zahlbr.) Elix & Hale, C. crozalsiana (de Lesd.) Elix & Hale, and C. ecaperata (Mull. Arg.) Elix & Hale are new to the South Korean lichen flora. An Artificial Key is provided for all species of Canoparmelia, including the three new records.

The Journal of Indian Botanical Society, 2012Co-Authors: D. Sheela, AvitaAbstract:Achene morphology of five species of Spilanthes Jacq. is investigated by light microscopy and scanning electron microscopy.
