In January 2024, the Philippine Taxonomic Initiative announced the publication of two new species descriptions from the Philippines in the Nordic Journal of Botany.

๐˜ฝ๐™ช๐™ก๐™—๐™ค๐™ฅ๐™๐™ฎ๐™ก๐™ก๐™ช๐™ข ๐™—๐™–๐™ง๐™˜๐™š๐™ก๐™ค๐™ฃ๐™–๐™š

Distribution/habitat: Mossy forest areas of the Pantabanganโ€“Carranglan Watershed Forest Reserve, Sitio Binbin, Carranglan, Nueva Ecija, Luzon (holotype discovered in 2021)

Endemic: Yes

Distinctive traits: ๐˜‰. ๐˜ฃ๐˜ข๐˜ณ๐˜ค๐˜ฆ๐˜ญ๐˜ฐ๐˜ฏ๐˜ข๐˜ฆ resembles another native flower, ๐˜‰. ๐˜ค๐˜ฉ๐˜ข๐˜ณ๐˜ช๐˜ด๐˜ข๐˜ฆ, but differs by having smaller vegetative parts, egg-shaped petals with a rounded tip, a labellum with two ridges that are strongly angled outwards the adaxial (upper) surface, rounded crests that are proximal (closer to the point of attachment), and a grooved lower surface. The species flowers in February, March, October and November, and fruits in February and November. When in full bloom, ๐˜‰. ๐˜ฃ๐˜ข๐˜ณ๐˜ค๐˜ฆ๐˜ญ๐˜ฐ๐˜ฏ๐˜ข๐˜ฆ’s flowers produce a woody scent; they open during daytime, and typically survive between 2 and 7 days.

Conservation status: Data deficient (DD)

Described by: Abigail Garrino & Raab Bustamante

Etymology: Named after Dr. Julie Barcelona, a pteridologist (expert on ferns and related plants), Rafflesia expert, and administrator/editor of Coโ€™s Digital Flora of the Philippines.

Distribution/habitat: Mossy forest areas of the Pantabanganโ€“Carranglan Watershed Forest Reserve, Sitio Binbin, Carranglan, Nueva Ecija, Luzon (holotype discovered in 2021)

Endemic: Yes

Distinctive traits: Thriving in moist, humid areas in mid-elevation forests, ๐˜‰. ๐˜ฑ๐˜ฆ๐˜ญ๐˜ด๐˜ฆ๐˜ณ๐˜ช resembles another orchid, ๐˜‰. ๐˜ข๐˜ถ๐˜ณ๐˜ฆ๐˜ฐ๐˜ฃ๐˜ณ๐˜ถ๐˜ฏ๐˜ฏ๐˜ฆ๐˜ถ๐˜ฎ, but with notable differences (including shorter leaves marked with small spots and pseudobulbs with sheaths that are shed early on). ๐˜‰. ๐˜ฑ๐˜ฆ๐˜ญ๐˜ด๐˜ฆ๐˜ณ๐˜ชโ€™s flowers bloom and fruit from October to November.

Conservation status: Data deficient (DD)

Described by: Jayson Mansibang & Raab Bustamante

Etymology: Named after Dr. Pieter Pelser, a biologist specializing in plant systematics, senior Lecturer at the School of Biological Sciences of University of Canterbury (Christchurch, New Zealand), and administrator/editor of Co’s Digital Flora of the Philippines.

Significance

With the discovery and description of ๐˜‰. ๐˜ฃ๐˜ข๐˜ณ๐˜ค๐˜ฆ๐˜ญ๐˜ฐ๐˜ฏ๐˜ข๐˜ฆ and ๐˜‰. ๐˜ฑ๐˜ฆ๐˜ญ๐˜ด๐˜ฆ๐˜ณ๐˜ช, the number of known Bulbophyllum species in the Philippines has increased to 207. In addition to emphasizing the need for further fieldwork and research in protected areas of the Philippines, the two new species highlight the critical, ongoing threats of illegal logging, land conversion, illegal wildlife trading, and poaching in the countryโ€”happening even in forest reserves such as the Pantabanganโ€“Carranglan Watershedโ€”as well as the devastating effects of climate change and deforestation on all species, especially those that are new to science.โ€”MF
