Gary D. Wallace, except as specified

Perennial, shrub, tree
Stem: bark often peeling distinctively
Leaves simple, generally cauline, alternate, opposite, rarely whorled, evergreen or deciduous, often leathery, petioled or not; stipules 0
Inflorescence: raceme, panicle, cyme, or flowers solitary, generally bracted; pedicels often with 2 bractlets
Flower generally bisexual, generally radial; sepals generally 4–5, generally free; petals generally 4–5, free or fused; stamens 8–10, free, filaments rarely appendaged, anthers awned or not, dehiscent by pores or slits; nectary generally at ovary base, disk-like; ovary superior or inferior, chambers generally 1–5, placentas axile or parietal, ovules 1–many per chamber, style 1, stigma head- to funnel-like or lobed

Subfamilies Monotropoideae, Pyroloideae, Vaccinioideae sometimes treated as families. Nongreen plants obtain nutrition from green plants through fungal intermediates.

MONOTROPA

Perennial, nongreen, glabrous to glandular-hairy; roots brittle, main often elongate
Stem 0

Fruit: capsule, loculicidal, erect, dehiscent tip to base
Seeds many per chamber, fusiform
Species in genus: 2 species: n hemisphere
Etymology: (Greek: 1 direction, from 1-sided inflorescence)

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
