[Botany • 2018] Sciaphila lambirensis (Triuridaceae) • A new mycoheterotrophic plant from Sarawak, Borneo, Malaysia

 

Sciaphila lambirensis Suetsugu, 

in Suetsugu. 2018.  

Borneo is known to harbor the greatest species diversity of the mycoheterotrophic genus Sciaphila (Triuridaceae) and is home to 11 species, including five endemics. Here, another undescribed Sciaphila species, Sciaphila lambirensis, which was discovered during a botanical survey in Lambir Hills National Park (Sarawak, Borneo, Malaysia) is reported along with a detailed morphological account. Sciaphila lambirensis is similar to S. brevistyla in having six equal perianth segments with a swollen apex bearing long hairs in both staminate and carpellate flowers. However, it is easily distinguishable by the secund arrangement of the flowers and the pedicel slightly recurved at its apex. A key to the species of Sciaphila in Borneo is provided.

Key words: Lambir Hills National Park, mycoheterotrophy, new species, taxonomy

[Botany • 2020] Sciaphila atra (Triuridaceae) • A New Mycoheterotrophic Species from Borneo


Sciaphila atra   

in Dančák, Hroneš & Sochor, 2020.

 Abstract
Sciaphila atra (Triuridaceae) from northern Borneo is described and illustrated. This species is similar to Sciaphila thaidanica from northern Thailand, but differs in distinctly darker stem and flowers, lower number of flowers, larger female flowers which usually have more tepals and wider tepals of male flowers. Taxonomy of Sciaphila secundiflora species complex is discussed in the paper. Key to currently accepted species of Sciaphila in Borneo is included.

Keywords: Malesia, rainforest, Sarawak, Sciaphila secundiflora complex, taxonomy, Monocots

[Botany • 2017] Sciaphila sugimotoi • A New Mycoheterotrophic Plant (Triuridaceae) from Ishigaki Island, Japan


 Sciaphila sugimotoi Suetsugu & T. Nishioka


Abstract

A new species of Sciaphila (Triuridaceae), Sciaphila sugimotoi Suetsugu & T. Nishioka, is described and illustrated from Ishigaki Island, Okinawa Prefecture, Japan. The new species is similar to S. arfakiana in having a stipitate globose to ellipsoid knob without hairs in apices of all male perianth segments. However, it is clearly distinguishable by its shorter pedicel, filament-connective not extended and thick stem. A key to the Japanese Sciaphila based on the whole flower characteristics and stylar characteristics, are provided for easy identification of these rare mycoheterotrophic plants.

Sciaphila sugimotoi Suetsugu & T. Nishioka, sp. nov.

 Type:— JAPAN. Ryukyu. Okinawa Pref., Ishigaki City, Hirae, alt ca. 180m, 18 October 2016, T. Sugimoto s.n. (holotype KYO!; isotype OSA!). 

Diagnosis:— Sciaphila sugimotoi is similar to Sciaphila arfakiana Beccari (1890: 337), but it differs by its shorter pedicel, its filamentconnective not extended and its thick stem.

 Etymology:— The new species is named after Mr. Takaomi Sugimoto, who collected ample specimens of this new species for the comparative study.

[Botany • 2016] Sciaphila yakushimensis • A New Mycoheterotrophic Plant (Triuridaceae) from Yakushima Island, Japan


Sciaphila yakushimensis
Suetsugu, Tsukaya & H. Ohashi 



A new species of Sciaphila (Triuridaceae), Sciaphila yakushimensis Suetsugu, Tsukaya & H. Ohashi, is described and illustrated from Yakushima Island, Kagoshima Pref., Japan. The new species is similar to S. nana, but it is clearly distinguishable by the blackish purple aerial parts, the clavate style with dense papillae, and the filaments not longer than the anthers. A key to the Japanese Sciaphila based on total flower characteristics and another based primarily on stylar characteristics are provided for convenience of easy identification of these rare mycoheterotrophic plants.

Key words: Distribution, Japan, mycoheterotrophic plants, new species, Sciaphila, Triuridaceae, Yakushima Island.
