Gaultherieae

Salal Gaultheria shallon, photographed by Mrs W. D. Bransford.


Belongs within: Vaccinioideae.

The Gaultherieae is a clade of plants in the Ericaceae containing the wintergreens (Gaultheria) and related species. The clade as a whole is not strongly supported, but a derived subgroup including Tepuia, Diplycosia, Pernettya and Gaultheria includes many species producing the fragrant compound methyl salicylate (Kron et al. 2002). Oil of wintergreen is used as a flavouring in products such as toothpaste and mouthwash. The type genus, Gaultheria, is characterised by having fruit surrounded by a persistent fleshy calyx, and stamens with flattened filaments and awned anthers (D. K. Trock).

Characters (from Kron et al. 2002): Shrubs, rarely lianas. Leaves evergreen or deciduous, entire, serrulate, or serrate, non-ericoid, convolute in bud. Leaf epidermal cells not lignified. Indumentum of multicellular, multiseriate glandular and non-glandular hairs. Inflorescence usually axillary, rarely terminal, racemose, paniculate, or fasciculate, occasionally reduced to a solitary flower; bracts present, bracteoles usually paired, variable in position; calyx articulated with pedicel. Flowers usually pentamerous, actinomorphic. Calyx lobes small to enlarged, often fleshy and colourful in fruit, persistent; corolla sympetalous, usually urceolate to tubular, lobes small. Stamens usually ten, filaments more or less straight, unicellular-pubescent, roughened, or smooth, lacking projections, or with four minute to conspicuous awns arising from dorso-apical portion of anther; anthers slightly to definitely roughened, occasionally with tubules, with or without a white deposit of disintegration tissue dorsally, dehiscing by terminal pores. Ovary usually pentalocular, with axile placentation, superior, rarely half inferior; style impressed; stigma more or less truncate. Fruit a loculicidal capsule or indehiscent berry, often associated with fleshy calyx; seeds usually with more or less isodiametric testa cells; embryo with two cotyledons.
