Begonia fritschiana from Mindanao Island is described as a new species endemic to the Philippines. This is the latest addition to the species-rich Begonia section Baryandra. It resembles Begonia caramoanensis but is distinguished by the consistent obliquely ovate leaves with shorter petioles, lamina glaucous abaxially and with marginal hairs, mostly solitary to singly-branched inflorescences with shorter white-glandular hairs on the pedicels and peduncle, one of the outer tepals pink, and glabrous ovary and ovary wings. Begonia fritschiana is known only from the type locality with one population and less than 100 individuals. The area is not currently protected under the country’s National Integrated Protected Areas System by the Department of Environment and Natural Resources. Because of ongoing threats such as illegal logging, poaching, and over collection of biological resources, the single area of occurrence with estimated extent < 10 km2, and the small number of < 100 individuals, we recommend a classification of B. fritschiana as Critically Endangered. 

Hypericum perryongii, from Mindanao Island, Philippines, is herein described and illustrated. This new taxon closely resembles both H. geminiflorum and H. formosanum but can be easily distinguished from the former by its larger corolla and calyx lobes and higher number of stamens per fascicle, and from the latter by its terminally 1-flowered inflorescences and the subsessile and abaxially glaucous leaves. 

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