Notes
Loher 12914 & 14901, from Luzon, confused by Foxworthy with H. plagata Vidal, appear to belong to this species, though the leaves are narrower and the nerves less prominent beneath.
H. ovoidea closely resembles H. semicuneata Sym. when sterile, but can nevertheless be distinguished by its brown, rather than grey-brown, drying leaves and small, canaliculate rather than pustular domatia which are at times absent; the pubescent ovoid ovary and rather stout connectival appendages (slender and thrice as long as the anthers in H. semicuneata) define this species.
