Storozhenkotettix, a new genus of Trusmaditetrigini (Orthoptera: Tetrigidae) from Mindanao, with notes on Bolivaritettix.

The Philippine archipelago houses an incredibly diverse biota, among which are 122 species of pygmy grasshoppers (Orthoptera: Tetrigidae). Many of them belong to genera without proper taxonomic assignment and some genera, e.g.

A DNA barcode reference of Asian ferns with expert-identified voucher specimens and DNA samples.

Ferns belong to species-rich group of land plants, encompassing more than 11,000 extant species, and are crucial for reflecting terrestrial ecosystem changes. However, our understanding of their biodiversity hotspots, particularly in Southeast Asia, remains limited due to scarce genetic data. Despite harboring around one-third of the world's fern species, less than 6% of Southeast Asian ferns have been DNA-sequenced.

A leading-edge scenario in the phylogeography and evolutionary history of East Asian insular in Taiwan and the Philippines.

The cool temperate origin of gymnosperm species in East Asia is specifically diverse and widespread. Certain lineages have managed to extend their distribution further south to subtropical and tropical islands such as Taiwan and the Philippines. To address questions including whether these insular lineages, recently identified as , have become genetically distinct from each other and from their continental relatives, and when and how they colonized their residing islands, we sampled over 11 populations, covering 179 individuals from Taiwan and the Philippines.

Comparative Morpho-Anatomical Studies of Two Philippine Endemic Species of . (Loranthaceae).

are epiphytic hemiparasitic plants on different types of woody host plants and are abundant in temperate, subtropical, and tropical regions. In Marilog Forest Reserve, Southern Philippines, two Philippine endemic species of were recorded, ., (Merr.

Horned and spiky: Tegotettix derijei sp. n. (Orthoptera: Tetrigidae) is a peculiar new pygmy grasshopper species from Mindanao.

A new peculiar, spiky, and yellowish species of the genus Tegotettix Hancock, 1913 is described from the Davao region of the island of Mindanao (the Philippines)-T. derijei sp. n.

, a new species of grass fern from Mindanao, Philippines.

Amoroso & Coritico (Schizaeaceae), from Mindanao, Philippines, is described herein as a new species. This species is distinguished from all other species of (grass ferns) by its notably short and narrow fronds, distinct triangular stipe, and bifid apex of the sorophore lamina with profuse white long hairs. This species is distinct from the other known Philippine species of by its diminutive epiphytic habit and a habitat restricted to the trunks of the tree fern (Baker) R.

Yellow Striped Giraffehopper Spartolus pugionatus Stål, 1877 comb. resurr. (Tetrigidae: Ophiotettegini) inhabits Mindanao Island of the Philippines' archipelago.

The genus Threciscus Bolívar, 1887 (Tetrigidae: Ophiotettigini) was a monotypic genus endemic for the Philippines and included only T. pugionatus (Stål, 1877). Here, after examination of series of specimens, we conclude that T.

(Orchidaceae), a new species from Mindanao, Philippines.

A new species, Tandang & Galindon (Orchidaceae), from Mindanao Island, Philippines is described and illustrated herein. This species is distinct from other known Philippine species by its terrestrial habit and is distinguished from all known species by its monopodial inflorescence, rarely branching in two, and a pale yellow to dull orange or brownish-yellow labellum devoid of purple spots.

(Ericaceae), a new species from Mindanao, Philippines.

P.W.Fritsch, a new species from Mindanao Island, Philippines, is described and illustrated.

Two New Nepenthes Species from the Philippines and an Emended Description of Nepenthes ramos.

With 50 species of the genus Nepenthes L. currently described from the Philippines, it is without doubt that the country, along with the islands of Sumatra (Indonesia) and Borneo (Indonesia, Malaysia, Brunei), should be considered the center of diversity of the genus. In this work, we describe two new species.

Molecular phylogeny and biogeography of the fern genus Pteris (Pteridaceae).

Background And Aims: Pteris (Pteridaceae), comprising over 250 species, had been thought to be a monophyletic genus until the three monotypic genera Neurocallis, Ochropteris and Platyzoma were included. However, the relationships between the type species of the genus Pteris, P. longifolia, and other species are still unknown.

Hamiguitan Range: A sanctuary for native flora.

Hamiguitan Range is one of the wildlife sanctuaries in the Philippines having unique biodiversity resources that are at risk due to forest degradation and conversion of forested land to agriculture, shifting cultivation, and over-collection. Thus, it is the main concern of this research to identify and assess the endemic and endangered flora of Hamiguitan Range. Field reconnaissance and transect walk showed five vegetation types namely: agro-ecosystem, dipterocarp, montane, typical mossy and mossy-pygmy forests.
