Monotropa uniflora is a species of plant from the genus Monotropa in the subfamily Monotropoideae within the heather family(Ericaceae). In the genus Monotropa there are only two types, the second type, the spruce asparagus ( Monotropa hypopitys L.) also occurs in Central Europe. Originally the genus Monotropa was placed in its own family of spruce asparagus plants (Monotropaceae).

Macro shot of the flower

Vegetative characteristics

Monotropa uniflora is a perennial, herbaceous plant that forms a rhizome for perpetuation . The plants do not contain any leaf green , but rather parasitize on their root fungi (myco heterotrophy ). This species differs from almost all other vascular plants by the white to pink color of the fleshy, waxy stems and inflorescences . Strong red specimens are rare. The aboveground plant parts are mostly bare. The plant parts turn black as they dry.

The leaves are reduced to 5 to 10 millimeters long scales.

Generative characteristics

At the end of the 10 to 30 centimeter long stem there is only one flower , which shows a certain similarity to the closely related species Monotropastrum humile and the distinction to the sister species Monotropa hypopitys . The flowers are usually 10 to 15 millimeters long and three to eight fold.

The upright capsule fruit is 1 to 1.5 centimeters long and ellipsoidal-spherical and contains several thousand seeds.

The seeds, which are about 0.1 millimeters long, are very small and elongated. The embryo is greatly reduced and consists of only four cells; the endosperm consists of only nine cells.

Chromosome set

The basic chromosome number is x = 8; it comes tetraploidy or Hexaploidie before, with a chromosome number of 2n = 32 or 48th

ecology

In contrast to most other plants, Monotropa species do not form chlorophyll . As an epiparasite , it gets its nutrients from mycorrhizal fungi on trees and bushes nearby. Monotropa species are not dependent on sunlight and can therefore grow in very dark locations in the undergrowth . Often near beeches .

Like most mycoheterotrophic plants, Monotropa uniflora only ever occurs in connection with a few specific hosts , all of which belong to the Russulaceae family .

English-language common names

English Ghost Plant, Ghost Pipe, Indian Pipe, Corpse Plant

distribution

The distribution area of Monotropa uniflora is disjoint . It occurs in Udmurtiya in the European part of Russia , in Asia (China, Tibet, Bangladesh, Bhutan, Nepal, Sikkim, India, Japan, Korea, maybe Myanmar) and is widespread from North to Central to northern South America .

Monotropa uniflora is generally rare.
