Quercus vacciniifolia
''Quercus vacciniifolia'' (sometimes spelled ''Q. vaccinifolia''), the huckleberry oak, is a member of the ''Protobalanus'' section of genus ''Quercus''. It has evergreen foliage, short styles, very bitter acorns that mature in 18 months, and a woolly acorn shell interior.
==Description==
''Quercus vacciniifolia'' is a shrubby evergreen of the oak family, which grows generally less than 1.5 m (5 feet) tall and spreads horizontally, never becoming a tree. In the field, it is best identified from its clustered terminal buds, which is characteristic of all plants of the genus. Species are more easily identified in the presence of acorns. Acorns of ''Q. vacciniifolia'' mature in 2 years (biennial maturation) after pollination. Flowers and inflorescence characteristics are not used to significant extend in this genera. ''Quercus vacciniifolia'' can be easily confused with ''Quercus cedrosensis'', which grows in dry chaparrals, such as California-Mexico border south, forests of Baja California and at higher elevations on Cedros Island.〔Kevin C. Nixton (2002) ''The Oak (Quercus) Biodiversity of California and Adjacent Regions'', USDA Forest Service Gen. Tech. Rep. PSW-GTR-184.〕 Morphologically, the two species differ in their leaf margins: while ''Q. vacciniifolia'' leaves are entire to mucro-toothed, ''Q. cedrosensis leaves'' are entire or have irregular spine-tipped teeth.〔〔(Flora of North America, ''Quercus vaccinifolia'' )〕
