Boschniakia is a genus of parasitic plants in the family Orobanchaceae. They are known commonly as groundcones and they are native to western North America and extreme northeastern Asia. Some taxonomists consider Boschniakia to be three separate genera: Boschniakia, Kopsiopsis , and Xylanche . [1] [2] When the genus is split, only a single species remains: Boschniakia rossica, the northern groundcone. [1] [3]

Groundcones are holoparasitic, meaning they depend entirely on a host plant for nutrients and contain little or no chlorophyll. These plants often parasitize alders but they are found on many other plants. Groundcones often look at first glance like pine cones lying on the ground, especially when they are brown in color. They may also be shades of yellow, red, and purple. Each plant may be a few inches tall, and pine-cone-shaped or cylindrical. The plant above ground is almost entirely made up of its inflorescence, a tightly packed column of thick cup-shaped flowers. The groundcone produces haustoria which penetrate the roots of its host and provide it with water and nutrients.

The type species for Boschniakia is Boschniakia glabra, a species which is no longer considered valid. Instead, it is now included in Boschniakia rossica. [4]

A pine is any conifer tree or shrub in the genus Pinus of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. Pine may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars recognized by the ACS.

Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta, also known as Coniferophyta or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews. The division Pinophyta contains seven families, 60 to 65 genera, and more than 600 living species.

<i>Rhinanthus minor</i> Species of flowering plant in the broomrape family Orobanchaceae

Rhinanthus minor, known as yellow rattle, is a herbaceous wildflower in the genus Rhinanthus in the family Orobanchaceae. It has circumpolar distribution in Europe, Russia, western Asia, and northern North America. An annual plant, yellow rattle grows up to 10–50 centimetres (3.9–19.7 in) tall, with upright stems and opposite, simple leaves. The fruit is a dry capsule, with loose, rattling seeds.

Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera were formerly included in the family Scrophulariaceae sensu lato. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing Orobanche major and relatives, but neither Paulownia tomentosa nor Phryma leptostachya nor Mazus japonicus.

Melampyrum is a genus of about 20 species of herbaceous flowering plants in the family Orobanchaceae known commonly as cow wheat. They are native to temperate regions of the Northern Hemisphere. They are hemiparasites on other plants, obtaining water and nutrients from host plants, though they are able to survive on their own without parasitising other plants.

Malpighiaceae is a family of flowering plants in the order Malpighiales. It comprises about 73 genera and 1315 species, all of which are native to the tropics and subtropics. About 80% of the genera and 90% of the species occur in the New World and the rest in the Old World.

<i>Conopholis americana</i> Species of flowering plant

Conopholis americana, the American cancer-root, bumeh or bear corn, is a perennial, non-photosynthesizing parasitic plant. It is from the family Orobanchaceae and more recently from the genus Conopholis but also listed as Orobanche, native but not endemic to North America. When blooming, it resembles a pine cone or cob of corn growing from the roots of mostly oak and beech trees.

<span class="mw-page-title-main">Closed-cone conifer forest</span>

A Closed-cone conifer forest or woodland is a plant community occurring in coastal California and several offshore islands. The forests typically have a single-aged single-species conifer overstory with dense ladder fuels. Overstory species include coulter pine, monterey pine, bishop pine, shore pine, and several endemic cypresses, species which generally rely on fire to open their cones and release seeds. Closed-cone forests often grow in low nutrient and/or stressed soils, which can lead to slow growth.

<i>Boschniakia rossica</i> Species of plant

Boschniakia rossica, commonly known as the northern groundcone, is a holoparasitic plant that lives in the northern latitudes of the northern hemisphere. In the Pacific Northwest Temperate Rainforest, it does not grow south of Prince of Wales Island, beyond that boundary is the Vancouver groundcone habitat. It does not contain chlorophyll, so it must be parasitic to obtain nutrients. It specializes on Alnus species, but can parasitize off of other trees and shrubs such as on Betula (birch), Salix (willow), Vaccinium (blueberry), Picea (spruce), and Chamaedaphne. This organism is likely to be found at mid elevations alongside rivers and streams, where moisture is abundant. This species propagates itself through water flow. In some places bears are known to have eaten the starchy roots, or tubers, of this plant.
