Homalomena brachygyna, a new species from the riparian forest of San Vicente, Palawan, is herein described. This novel addition to the Homalomena species of the Philippines bridges the gap of more than 100 years since the last described species from the country. It is also the second endemic Homalomena species in the island of Palawan. Descriptions, photographs, as well as notes on its habitat and ecology, phenology, and preliminary IUCN conservation assessment are provided.

In documenting the flora of Mt. Malinao, Albay Province, Bicol region, Philippines an unknown Begonia from section Petermannia was discovered in the higher altitudes. Further study of relevant specimens and protologue identified it as Begonia jagori, a species endemic to the Philippines. Begonia jagori was known from a single collection in 1861 and since then, it has not been recollected or redocumented again. The collection locality was listed broadly as Luzon, and the protologue lacked some details. Using the materials from Mt. Malinao, the plant was redescribed and lectotypified. A note comparing its affinity to B. cumingiana is provided.

Begonia masilig and Begonia akaw, both endemic to Aurora Memorial National Park, Luzon, Philippines, are described as species new to science. Begonia masilig is similar to B. droseroides in its rhizomatous habit and glandular trichomes on the inflorescence, but differs in lamina shape and overall size, and the vestiture of stipule, lamina margin, and outer tepals of staminate flowers. Begonia akaw is similar to B. ramosii in its short erect habit, ovate lamina and congested terminal inflorescence with 2-tepaled staminate flowers, but differs in inflorescence size and arrangement, and bract and ovary shape. Both new species are here proposed to be Endangered (EN) as per IUCN criteria.
