| description | Recollection of Ooia grabowskii at the Type locality in Kalimantan Selatan,
Indonesian Borneo, has revealed the name to have been comprehensively misapplied to
five taxonomically new Bornean Ooia species, here described as: Ooia altar S. Y. Wong
& P. C. Boyce, sp. nov., O. basalticola S. Y. Wong & P. C. Boyce, sp. nov., O. glans S. Y.
Wong & P. C. Boyce, sp. nov., O. secta S. Y. Wong & P. C. Boyce, sp. nov., and O. suavis
S. Y. Wong & P. C. Boyce, sp. nov. Ooia grabowskii is endemic to the southern portion of
the Meratus Mountains, Kalimantan Selatan. Clarification of O. grabowskii additionally
reveals that Rhynchopyle havilandii Engl. [≡ Piptospatha havilandii (Engl.) Engl.;
Schismatoglottis havilandii (Engl.) M. Hotta], until now treated as a heterotypic synonym
of O. grabowskii, to be a distinct species of Ooia: the combination Ooia havilandii (Engl.)
S. Y. Wong & P. C. Boyce, comb. nov. is made. Newly observed spathe senescence
mechanics of O. grabowskii and O. basalticola are strikingly in agreement with those
of Piptospatha manduensis Bogner & A. Hay. Combined with the highly atypical (for
Piptospatha) fragrant inflorescences, pubescent staminate flowers, and deciduous
non-pistillate flowers, and typical (for Ooia) creeping/rooting stems and pendulous
infructescences occurring in P. manuduensis prompts removal of P. manduensis from
Piptospatha and incorporation into Ooia – the combination Ooia manduensis (Bogner &
A. Hay) S. Y. Wong & P. C. Boyce, comb. nov. is made. These novelties and transfers,
taken together with pre-existing species, brings Ooia to 10 species. All species are
illustrated from living plants, with Ooia grabowskii additionally figured from the Berlin
Holotype, and from Engler’s Araceae Exsiccatae et Illustratae No. 196. An identification
key to all described Ooia species is provided. |
